[Q] Writing in an XML File Problem

Hey Guys!
I'm sitting in front of an XML-Problem for five days now and really don't know what's to do. Expect of asking you.
I want to write a small shopping list application that manages the data in an XML-File looking like that:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
(...)
I have a ListBox called ItemShowcase that I fill with instances of my ShowCaseEntry-Class
Reading Data from the FIle works perfectly with this code:
Code:
private void updateItemList()
{
// load XML-File
var items = XElement.Load("MissingItems.xml");
foreach (var a in items.Elements())
{
ShowCaseEntry sce = new ShowCaseEntry(a.Element("Name").Value, "Store: " + a.Element("Store").Value, false);
ItemShowcase.Items.Add(sce);
}
}
No Problem until here.
But now I want to add a new Iem to my XML-File.
I have 2 Textfields in what I ask for the Item-Name and Store-Name. Repeat is always true.
I tried that:
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
// XML-Datei Laden
var items = XDocument.Load("MissingItems.xml");
// neues Item erstellen
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat) );
// Hinzufügen und spreichern
items.Root.Add(newItem);
FileStream F = new FileStream("MissingItems.xml", FileMode.Open);
items.Save(F);
}
The last line give me the following Error:
Attempt to access the method failed: System.IO.FileStream..ctor(System.String, System.IO.FileMode)
Is anyone here who would help me?
You would save my weekend!
Thank you so much!
Best wishes and greets
Robby

Try something like this:
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
xml.Save(isoStream);
isoStream.Close();

First of all thanks for your answer.
Unfortunately I don't really know how to add the XML-Items.
Like this?
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
var items = XDocument.Load("MissingItems.xml");
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat));
items.Root.Add(newItem);
items.Save(isoStream);
isoStream.Close();
}
Another answer would be very nice
Best regards
Robby

I don't have time to test it but hopefully this works for you.
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
XDocument items = XDocument.Load(isoStream);
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat)));
items.Save(isoStream);
isoStream.Close();
}

Thank you really much for your engangement, but there is still one problem.
In this line the program throws an XML-Error called "root element is missing":
XDocument items = XDocument.Load(isoStream);
How to explain the Load-Method that "Items" is my root Element?

Sorry my code had errors. This is tested and working.
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument items = XDocument.Load(isoStream);
isoStream.Close();
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat.ToString())));
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
items.Save(isoStream);
isoStream.Close();
That code results in this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
<Item>
<Name>Test Name</Name>
<Store>Test Store</Store>
<Repeat>False</Repeat>
</Item>
</Items>

I really, really thank you for your anxiety. Thank you for your time, but I just have one more error.
This line throwes an Isolated Storage Exception called "Operation not permitted on IsolatedStorageFileStream.":
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
You would save my week with a short answer!
Thank you so much till yet
Robby

It sounds like the file stream is already open somewhere else. If you are doing any other reads or writes to the file prior to your addxmlitem method you need to close the stream before calling addxmlitem.

Not really
Sorry, I am sure that I'm annoying but I really need to fix that problem.
My last try to solve ist is to send you the full code:

public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument items = XDocument.Load(isoStream);
isoStream.Close();
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat.ToString())));
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
items.Save(isoStream);
isoStream.Close();
}
/// <summary>

foreach (var a in items.Elements())

ItemShowcase.Items.Add(sce);
}
}
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
}
private void btnAdd_Click(object sender, RoutedEventArgs e)
{
addXMLItem(tBoxAddItemName.Text, tBoxAddItemStore.Text, false);
//updateItemList();
}
}
}
Can you find any mistakes?
I'm getting desperate...
Thanks a lot for your engagement!

I'n not really sure why that's happening. The only thing I can think of is XElement.Load() is causing the problem so here's how to use XDocument.Load() instead. I really hope this works for you because I'm out of ideas.
Code:
private void updateItemList()
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument xml = XDocument.Load(isoStream);
var items = from c in xml.Elements("Items").Elements("Item")
select new {
name = c.Element("Name").Value,
store = c.Element("Store").Value,
repeat = c.Element("Repeat").Value
};
foreach (var item in items)
{
ShowCaseEntry sce = new ShowCaseEntry(item.name, "Store: " + item.store, false);
ItemShowcase.Items.Add(sce);
}
isoStream.Close();
}

Same Error on this line:
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
Operation not permitted on IsolatedStorageFileStream.
I'm at the end of my motivation
I really tried everything, you really tried everything and I cannot find anything helpful to this error message..
Does anyone has an idea?
Does this line works for you?
Big Thanks to Ren13B till yet!

Attached is my working test project. Maybe it will help you.

If you are accessing the Isolated Storage from within a referenced assembly, you will need to access the IsolatedStorageFile for that assembly

Thanks for your reply but how to do that?

[Q] WP7 - Removing an XElement from an XML file

In short, I can add or edit, but cannot DELETE an XElement...
Any ideas?
Thanks in advance!

Can you post the code you are using for XElement.Remove and use code tags so the formatting is right. Its the # button on the post toolbar.

Well, I did nothing special, just the XML_Element.remove, instead of adding a new xelement.
Then the error raises whenever I try to reopen the XML file.
My point is, how can I delete an specific xelement?
As far as I know, the following code should work
Code:
Dim XML_XElement As XElement = XML_Document.Descendants("Carts").Where(Function(c ) c.Element("CART_NAME").Value.Equals("First")).Firs tOrDefault()
If XML_XElement IsNot Nothing Then
XML_XElement.SetElementValue("CART_NAME", "Third")
Else
' remove the selected record
XML_XElement.Remove
End If
Honestly I don't know if the foregoing code is correct or if the issue is related to how WP7 handles the removal thus corrupting the original file.
Please let me know if you need anything else.
Any help is very appreciated!
PS: Thanks for the other replies, helped a lot!

Here's how I did it in c#. My xml file is very different than yours so the query will be different but the important parts are where you load and close the file streams and then write.
Code:
//Get users private store info
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
//open selected file
isoStream = new IsolatedStorageFileStream(list, System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument xml = XDocument.Load(isoStream);
isoStream.Close();
//Find section
XElement sectionElement = xml.Descendants("section").Where(c => c.Attribute("name").Value.Equals(groupn)).FirstOrDefault();
//Find item and remove it
sectionElement.Elements("setting").Where(c => c.Attribute("name").Value.Equals(litem)).FirstOrDefault().Remove();
isoStream.Close(); //Seems unnecessary but it's needed.
//Write xml file
isoStream = new IsolatedStorageFileStream(list, FileMode.Create, FileAccess.Write, isoStore);
xml.Save(isoStream);
isoStream.Close();

Thanks again for your help, greatly appreciated.
However I'm still getting the same error.
Sorry for asking, but are you getting any errors when deleting in WP7 ?
My knowledge on XML is extremely new and I'm sure that I'm making some mistakes somewhere...
But so far, I cannot get past the same exception.
Seems that the XML gots "corrupted" after the delete operation.
On the other hand, if is not too much to ask for, using my current code, how will handle the delete of the selected record?
Thanks!

I have no problem at all removing elements in c#. I don't have vb support even installed right now. If you think it's a bug you should post on the forums at http://forums.create.msdn.com/forums/98.aspx

Problem is my country is not listed so I cannot register...
Here is the C# version of my current code for adding/editing
Code:
public static void ADD_XML_Record()
{
string File_to_Create = "Tracks.xml";
var XML_IsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
// Check that the file exists if not create it
if (! (XML_IsolatedStorage.FileExists(File_to_Create)))
{
return;
}
StreamReader XML_StreamReader = new StreamReader(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Read));
XDocument XML_Document = XDocument.Parse(XML_StreamReader.ReadToEnd());
XML_StreamReader.Close();
// Update the element if it exist or create it if it doesn't
XElement XML_XElement = XML_Document.Descendants("Carts").Where((c) => c.Element["CART_NAME"].Value.Equals("dd")).FirstOrDefault();
if (XML_XElement != null)
{
XML_XElement.SetElementValue("CART_NAME", "bbbbb");
}
else
{
// Add new
XElement newProgress = new XElement("Carts", new XElement("CART_NAME", "dd"), new XElement("CART_COLOR", "ff"));
XElement rootNode = XML_Document.Root;
rootNode.Add(newProgress);
}
using (StreamWriter XML_StreamWriter = new StreamWriter(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Write)))
{
XML_StreamWriter.Write(XML_Document.ToString());
XML_StreamWriter.Close();
}
}
I tried your code but I'm having a bad time making it to work.
If not a big deal, please could you tell me how to modify it ?
I mean, if a record is found, instead of editing, to remove it?
Honestly I'm stuck and any help is more than apprecisted!

[CODEPLEX PROJECT] HTC RomUpdateUtility in .NET 4

Hi everyone,
Today i come here with ideas.....
which is
HTC RUU in .NET Flavour
you can browse for nbh file, not locked at current folder with this tool
the project has its site located at: http://htcruunet.codeplex.com
i hope anyone want to collaborate in this project, because, my c# skill is SEVERLY WEAK.
Dev. Status:
-Prototype (UI Design)

Something like that:
Whitestone Advanced ROM Update Utility
Kovsky Advanced ROM Update Utility
Topaz Advanced ROM Update Utility
Blackstone Advanced ROM Update Utility
Mozart Advanced ROM Update Utility
LEO Advanced ROM Update Utility
by Barin????....
The main benefit is .Net 4 (Barin used 3.5) and possibility not to put nbh to one folder with the flasher?
Or again - adding "eye candy" features? Maybe pink dots on main window?
Funny

don't talk sinister here
---------------------------------------------------------------------------
ok, the differences is, i aimed to make it open source, but, barin's closed
so, the benefit is, people can learn how RUU works, not just a frickin' eye candy.
that's it
---------------------------------------------------------------------------
come on, grow up, we're here to learn, develop, share, not to talk sinister

Useless guy, but actually the idea is cool - kinda: "guys, I will start VS project and make interface. The rest is almost nothing - code and full functionality - should be done by you guys - and you will be co-authors... Maybe....". Nice!

well, i'm not spamming, i have a working program (WPE4), but, in this case, i only can design the program, but, i got stuck when thinking about SPL commands, so, this is why i made it in codeplex, to make it open source, and collaborate, if you like to collaborate in this project, you're welcome
and, if you think that my project(s) is totally USELESS, then, do not use it, easy, right

@aramadsanar
If you want an advice:
1. Do not import all available assemblies into your project, just use only neccesery.
2. Use "Public" definition only if you want to provide access to your functions or variables from external programs.
3. Avoid default naming of controls - after a few weeks you will forget what is your button for (for example), especially if you plan to change some of its properties programmatically later.
4. If you want to write RUU try to use stock RUU as external executable in your program at first
Good luck!

Need help for a simple text app

I was wondering, if someone can guide to create a simple app which simplly displays some text on the middle of the screen and 2 buttons (Left and right arrow) to switch to the next or previous text.
I think someone just helped another user who was looking for help for something similar like me but I cannot find it.
Thanks

You can try out this sample code, starting from an empty silverlight project:
In the MainPage.xaml, add the following snippet inside the Grid element named "ContentPanel".
<TextBlock Name="tblkDisplay" Width="360" Height="100" VerticalAlignment="Top" Margin="0,200,0,0" TextAlignment="Center"></TextBlock>
<Button Name="btnBack" Width="160" Height="80" VerticalAlignment="Top" Margin="-200,308,0,0" Click="btnBack_Click">Back</Button>
<Button Name="btnForward" Width="160" Height="80" VerticalAlignment="Top" Margin="200,308,0,0" Click="btnForward_Click">Forward</Button>
This markup adds a TextBlock, and Forward and Back buttons to the page.
In the in the code-behind (MainPage.xaml.cs), use the following code:
Code:
private int _displayIndex; //position in list of text items to display
private List<string> _textItems; //List of text items to display
// Constructor
public MainPage()
{
InitializeComponent();
}
//Code that get called when the page is navigated to
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
_textItems = new List<string>();
//Add ten items to text list to display
for (int i = 0; i < 10; i++)
{
_textItems.Add("Item" + i.ToString());
}
//For the default, set to first position and display it
_displayIndex = 0;
tblkDisplay.Text = _textItems[_displayIndex];
}
//If not at the first position of the list decrement by one, otherwise move to end of the list
private void Back()
{
if (_displayIndex > 0)
{
_displayIndex--;
}
else
{
_displayIndex = _textItems.Count - 1;
}
}
//If not at the last position of the list increment by one, otherwise move to start of the list
private void Forward()
{
if (_displayIndex < _textItems.Count - 1)
{
_displayIndex++;
}
else
{
_displayIndex = 0;
}
}
private void ShowText()
{
if ((_textItems.Count > 0) //Make sure there are items in the collection to display
&& (_displayIndex < _textItems.Count) // Make sure the index is not higher than how many items in the collection
&& (_displayIndex >= 0)) //Make sure the index is zero or greater
{
tblkDisplay.Text = _textItems[_displayIndex];
}
else
{
tblkDisplay.Text = "No Items.";
}
}
private void btnBack_Click(object sender, RoutedEventArgs e)
{
Back();
ShowText();
}
private void btnForward_Click(object sender, RoutedEventArgs e)
{
Forward();
ShowText();
}

Development Guide for Integrating Share Kit on Huawei Phones

View attachment 5209541
What is Share Engine
As a cross-device file transfer solution, Huawei Share uses Bluetooth to discover nearby devices and authenticate connections, then sets up peer-to-peer Wi-Fi channels, so as to allow file transfers between phones, PCs, and other devices. It delivers stable file transfer speeds that can exceed 80 Mbps if the third-party device and environment allow. Developers can use Huawei Share features using Share Engine.
The Huawei Share capabilities are sealed deep in the package, then presented in the form of a simplified engine for developers to integrate with apps and smart devices. By integrating these capabilities, PCs, printers, cameras, and other devices can easily share files with each other.
Three SDK development packages are offered to allow quick integration for Android, Linux, and Windows based apps and devices.
Working Principles
Huawei Share uses Bluetooth to discover nearby devices and authenticate connections, then sets up peer-to-peer Wi-Fi channels, so as to allow file transfers between phones, PCs, and other devices.
View attachment 5209543
To ensure user experience, Huawei Share uses reliable core technologies in each phase of file transfer.
Devices are detected using in-house bidirectional device discovery technology, without sacrificing the battery or security
Connection authentication using in-house developed password authenticated key exchange (PAKE) technology
File transfer using high-speed point-to-point transmission technologies, including Huawei-developed channel capability negotiation and actual channel adjustment
For more information you can follow this link.
Let’s get into codding.
Requirements
For development, we need Android Studio V3.0.1 or later.
EMUI 10.0 or later and API level 26 or later needed for Huawei phone.
Development
1 - First we need to add this permission to AndroidManifest.xml. So that we can ask user for our app to access files.
XML:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
2 - After let’s shape activity_main.xml as bellow. Thus we have one EditText for getting input and three Button in UI for using Share Engine’s features.
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp"
tools:context=".MainActivity">
<EditText
android:id="@+id/inputEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="32dp"
android:hint="@string/hint"
tools:ignore="Autofill,TextFields" />
<Button
android:id="@+id/sendTextButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:onClick="sendText"
android:text="@string/btn1"
android:textAllCaps="false" />
<Button
android:id="@+id/sendFileButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:onClick="sendFile"
android:text="@string/btn2"
android:textAllCaps="false" />
<Button
android:id="@+id/sendFilesButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:onClick="sendMultipleFiles"
android:text="@string/btn3"
android:textAllCaps="false" />
</LinearLayout>
3 - By adding the following to strings.xml, we create button and alert texts.
XML:
<string name="btn1">Send text</string>
<string name="btn2">Send single file</string>
<string name="btn3">Send multiple files</string>
<string name="hint">Write something to send</string>
<string name="errorToast">Please write something before sending!</string>
4 - Later, let’s shape the MainActivity.java class. First of all, to provide access to files on the phone, we need to request permission from the user using the onResume method.
Java:
@Override
protected void onResume() {
super.onResume();
checkPermission();
}
private void checkPermission() {
if (checkSelfPermission(READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
String[] permissions = {READ_EXTERNAL_STORAGE};
requestPermissions(permissions, 0);
}
}
5 - Let’s initialize these parameters for later uses and call this function in onCreate method.
Java:
EditText input;
PackageManager manager;
private void initApp(){
input = findViewById(R.id.inputEditText);
manager = getApplicationContext().getPackageManager();
}
6 - We’re going to create Intent with the same structure over and over again, so let’s simply create a function and get rid of the repeated codes.
Java:
private Intent createNewIntent(String action){
Intent intent = new Intent(action);
intent.setType("*");
intent.setPackage("com.huawei.android.instantshare");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
return intent;
}
We don’t need an SDK to transfer files between Huawei phones using the Share Engine, instead we can easily transfer files by naming the package “com.huawei.android.instantshare” to Intent as you see above.
7 - Let’s create the onClick method of sendTextButton to send text with Share Engine.
Java:
public void sendText(View v) {
String myInput = input.getText().toString();
if (myInput.equals("")){
Toast.makeText(getApplicationContext(), R.string.errorToast, Toast.LENGTH_SHORT).show();
return;
}
Intent intent = CreateNewIntent(Intent.ACTION_SEND);
List<ResolveInfo> info = manager.queryIntentActivities(intent, 0);
if (info.size() == 0) {
Log.d("Share", "share via intent not supported");
} else {
intent.putExtra(Intent.EXTRA_TEXT, myInput);
getApplicationContext().startActivity(intent);
}
}
8 - Let’s edit the onActivityResult method to get the file/s we choose from the file manager to send it with the Share Engine.
Java:
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && data != null) {
ArrayList<Uri> uris = new ArrayList<>();
Uri uri;
if (data.getClipData() != null) {
// Multiple files picked
for (int i = 0; i < data.getClipData().getItemCount(); i++) {
uri = data.getClipData().getItemAt(i).getUri();
uris.add(uri);
}
} else {
// Single file picked
uri = data.getData();
uris.add(uri);
}
handleSendFile(uris);
}
}
With handleSendFile method we can perform single or multiple file sending.
Java:
private void handleSendFile(ArrayList<Uri> uris) {
if (uris.isEmpty()) {
return;
}
Intent intent;
if (uris.size() == 1) {
// Sharing a file
intent = CreateNewIntent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_STREAM, uris.get(0));
} else {
// Sharing multiple files
intent = CreateNewIntent(Intent.ACTION_SEND_MULTIPLE);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
}
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
List<ResolveInfo> info = manager.queryIntentActivities(intent, 0);
if (info.size() == 0) {
Log.d("Share", "share via intent not supported");
} else {
getApplicationContext().startActivity(intent);
}
}
9 - Finally, let’s edit the onClick methods of file sending buttons.
Java:
public void sendFile(View v) {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.setType("*/*");
startActivityForResult(i, 10);
}
public void sendMultipleFiles(View v) {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
i.setType("*/*");
startActivityForResult(i, 10);
}
We’ve prepared all the structures we need to create, so let’s see the output.
