Deploy XAP without Visual Studio

Is it possible to deploy my XAP file without using Visual Studio in either hacked or original emulator image?

With XNA tool WP.exe you can install .xap to Emulator or Device WITHOUT VisualStudio.
On my machine, XNAGSv4=C:\Program Files\Microsoft XNA\XNA Game Studio\v4.0\Tools
Command:
wp install [options] <xap> <app id> <icon> <xapcache>
Example:
%XNAGSv4%\Tools\wp.exe install HellpWP7.xap 71f6d153-0759-4d6e-9bcd-de9a49d8f232 ApplicationIcon.png XapCacheFile.xml
* app id: The GUID found in Propeties\AssemblyInfo.cs
* ApplicationIcon.png: Found in the output directory.
* XapCacheFile.xml: Found in the intermediate (obj) directory.

I have read that the approach using wp.exe from XNA only works for XNA apps. Here is another approach which makes use of CoreCon API: h**p://justinangel.net/WindowsPhone7EmulatorAutomation

Nice, and only your second post.. Where did you get this?

That's reflected from XapDeploy

You will have to use XapDeploy tool. It requires Zune running on the same environment. You can also use WPConnect, a console tool, if you have Zune installed, see msdn.microsoft.com/en-us/library/gg180729(VS.92).aspx

[Q] Developing app that requires root - freezes after asking for su

I am new to android development and am having an issue. I am working on an app that requires root and when I request it using this code:
Code:
Runtime.getRuntime().exec(new String[] {"su"});
I get the request, Allow it then the app locks up and doesn't go to the next item. I am trying to figure out the debugging environment in eclipse, but have not figured out a way to debug this. Is there something I need to do after acquiring root? The next line of code is a simple Toast, so I know it is locking up at the su command. Is there any documentation on writing root apps anybody can point me to? Or is there a simple answer? Thanks in advance.
EDIT: Just in case the whole code will help, here it is:
Code:
public class toggle extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);
String[] results = executeShellCommand(new String[] {"su"});
Toast toast = Toast.makeText(this, results[0], Toast.LENGTH_SHORT);
toast.show();
finish();
}
public String[] executeShellCommand(String[] args) {
Process mLogcatProc = null;
BufferedReader reader = null;
BufferedReader errorReader = null;
String logResult = null;
String errorLogResult = null;
String separator = System.getProperty("line.separator");
try
{
mLogcatProc = Runtime.getRuntime().exec(args);
reader = new BufferedReader(new InputStreamReader(mLogcatProc.getInputStream()));
errorReader = new BufferedReader(new InputStreamReader(mLogcatProc.getErrorStream()));
String line;
final StringBuilder log = new StringBuilder();
while ((line = reader.readLine()) != null)
{
log.append(line);
log.append(separator);
}
logResult = log.toString();
String errorLine;
final StringBuilder errorLog = new StringBuilder();
while ((errorLine = errorReader.readLine()) != null)
{
errorLog.append(errorLine);
errorLog.append(separator);
}
errorLogResult = errorLog.toString();
if((logResult.length() == 0) || (errorLogResult.length() > 0))
{
if(errorLogResult.length() > 0)
{
return errorLogResult.split(separator);
}
else
{
return (new String[] {"null_result"});
}
}
else
{
return logResult.split(separator);
}
}
catch (Exception e)
{
return (new String[] {e.toString()});
}
finally
{
if (reader != null)
try
{
reader.close();
}
catch (IOException e)

Need Developer Help - Form Refreshing

Hello,
i started to wrote my first WO7 applicatin.
I got following code:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
...
}
...
}
My Problem is that the content of the Button doesn't change to "Calculating". Even my Progressbar:
Code:
private void PbStep()
{
if (Pb1.Value == Pb1.Maximum)
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
else
{
Pb1.Value = Pb1.Value + 1;
}
}
It is wrapped in s loop, and the bar begins with 0 and then switsch to 100%, but i cant see the steps between.
I think i need a refresh command. in visual basic it is Me.Update();.
I tried many codes from google, but nothing helped. I hope some1 can help me.
many thank

Try
Code:
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});

i did already try this. but now when i press the button, while calculation nothing happens, and after the calculation is finished, the button content changes to "calculating" and don't changes back to "start".
so i put the code in both parts and now i got the same as before. the button did not change its content
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "";
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});
Pb1.Value = 0.0;
Pb1.Maximum = Max;
DateTime StartZeit = DateTime.Now;
for (int i = 0; i < Pb1.Maximum; i++)
{
PbStep();//Count Up PorgressBar
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Start";
});
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
But thank you for your help. any other ideas?

you really need to be looking at a background thread (background worker control may allow you do do this)
any tight loop like that will freeze the UI until the loop has finished
in the 'old days' a doevents within the loop itself would have been suffice but this is not good practice
HTH

Try this one, it does what you've trying to implement but using a correct way:
Code:
using System.Windows.Threading;
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(100);
timer.Tick += (_, __) =>
{
// Here is replacement of your PbStep()
Pb1.Value++;
};
timer.Start();
}

i got it now this way:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "Duration: Calculating...";
BtnStart.Content = "Wait";
DateTime StartZeit = DateTime.Now;
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(1);
timer.Tick += (_, __) =>
{
for (int i = 0; i < Pb1.Maximum; i++)
{
Pb1.Value++;
}
timer.Stop();
LblDuration.Text = "Duration: " + (DateTime.Now - StartZeit).ToString();
BtnStart.Content = "Start";
};
timer.Start();
}
It is half working. When i press Start, the button changes its content imediatly and after finishing the loop it return to its default content.
now i got 2 problems:
1. the progressbar isnt smooth jet
and the bigger one:
2. i wanted to create a benchmark programm an measure how long it takes to count a progressbar from 0 to 1million. now with the timer i dont have the real cpu speed because it is always waiting for the timer to tick. so the benchmark is sensless
@ cameronm:
I know the DoEvent command from other languages, but i wans able to use this in c#. i mainly programm in visual basic, cause this seems to be easy (In this case i would use Me.Update). I have heard from the Background worker, but never tried it. Maybe this can help.
I will do some google search and try to use the Background worker. I'll post again if i got new code
Thanks you all !

hello again
im now that far:
Code:
public partial class MainPage : PhoneApplicationPage
{
//Globale Variablen
private BackgroundWorker bw = new BackgroundWorker();
public int Max = 0;
// Konstruktor
public MainPage()
{
InitializeComponent();
Max = 500000;
bw.WorkerReportsProgress = true;
bw.WorkerSupportsCancellation = true;
bw.DoWork += new DoWorkEventHandler(bw_DoWork);
bw.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);
bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);
}
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
if (bw.IsBusy != true)
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
Pb1.Value = 0.0;
Pb1.Maximum = Max;
bw.RunWorkerAsync();
}
}
private void BtnStop_Click(object sender, System.Windows.RoutedEventArgs e)
{
if (bw.WorkerSupportsCancellation == true)
{
bw.CancelAsync();
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
DateTime StartZeit = DateTime.Now;
//Failure by any deklarion
//like int i = 0 or BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
if ((worker.CancellationPending == true)) //Abbruchbedingung
{
e.Cancel = true;
break;
}
else //Progressbedingung
{
PbStep();//Count Up PorgressBar
}
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
BtnStart.Content = "Start";
}
private void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if ((e.Cancelled == true))
{
this.LblStatus.Text = "Canceled!";
}
else if (!(e.Error == null))
{
this.LblStatus.Text = ("Error: " + e.Error.Message);
}
else
{
this.LblStatus.Text = "Done!";
}
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
In the DoWork Function i receive an error when i try to set a variable like int i=0.
The Failure:UnauthorizedAccessException: Invalid cross-thread access
i followed this instruction: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
but there they did the same. why did i have the error?

The exception you've got show exactly what's wrong: you are trying to access GUI thread variables from another (BackgroundWorker) thread.
Use Dispatcher.Invoke as I recommended to you a few posts above.

thank you sensboston. id dont understand why, because i just have one bgworker, but now it works
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
if (bw.IsBusy != true)
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
Pb1.Value = 0.0;
Pb1.Maximum = Max;
bw.RunWorkerAsync();
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
DateTime StartZeit = DateTime.Now;
Dispatcher.BeginInvoke(() =>
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
if ((worker.CancellationPending == true)) //Abbruchbedingung
{
e.Cancel = true;
break;
}
else //Progressbedingung
{
Pb1.Value = Pb1.Value + 1;
//PbStep();
}
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
BtnStart.Content = "Start";
});
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
Just my progressbar isnt running fluently. still just 0% (before calc) or 100% (after calc) and no steps between

It's simple, dear Watson: your code updating progress bar too fast, without delays needed for GUI updates

yep agree with this .. what you are actually doing in the loop is not enough for you to acutally see the progressbar update .. fast little things these phones of ours

yeah, this was the first i tryed, before posting in this forum.
delay() did not work in c#.
Application.DoEvents() should work if i can believe google, but visual studio says there is no definition for doevents().
So i used
Code:
Pb1.Value++;
System.Threading.Thread.Sleep(1);
after each progressbar.value++, but this either didnt work...
what is the secret?

1 millisecond will not be enough to slow it down either
Maybe try 1000 instead ..

something else i thought of too ..
you may want to think about your design
If a progress bar is going to just flash up and complete as what you are doing is too fast .. you need to think 'is a progress bar the right control to use'
if you are going to increase the amount of work your background thread is going to do then I would say keep the progress bar
If the background thread is going to be this quick always .. then maybe a label saying 'please wait' ... and then hide the label when done .. or something similar

i tried with 1000 ms but this progress bar isnt running.
@cameronm: i want to create a "benchmark app" where the cpu counts the progressbar to 1million and measures the time. the time measuring is working correctly. i just want to get a nice GUI with a running bar, like it runs when you download and install apps from the market.
i was very long googling and found commands like progressbar.PerfomStep(); like described here http://www.java2s.com/Code/CSharp/GUI-Windows-Form/ProgressBarinC.htm
this is also c#, but i cant perfom this command. did i miss some assembly, headers or so? or is it because im doint a windows phone form and that there are less command than in a normal windows application?

You want to make a Benchmark app and you actually used :System.Threading.Thread.Sleep(*int)...!
This is not Benchmarking.
Background Worker like any other ThreadTypeClass should report it's progress via the BackgroundWorker_ProgressChanged_Event(..args).
Inside the Event either u PerformStep() either you implement your own code logic.
If even after this the worker fills instanly like "cameronm" said above then consider making the backgroundworker's Job a bit heavier or leave the progressBar and even the seperated background thread Idea cause it is not Needed.

yes, i am not luck with using a sleep command
PerformStep() is not accepted by the compiler
so you mean just counting up is to "easy". what progress could be "heavier". now i understand what cameronm meant^^
in the evening i will try more difficult calculations like sqare and multiplication of integers. would that be heavy enough?

Typing from LG quantum
Try this: make your calculations in a for loop 1-100..at each loop make progressbar.value++ .

You should be calling ReportProgress and then updating the Progress Bar in the Progress Changed function.
See: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx

@PG2G
the link you posted was exactly the source where i learned to implement the bw_worker. but with the command you told me i got an failure in the marked line (see source code comment). It says: InvalidOperationException: Operation has already been completed.
Code:
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
double a, b, c;
DateTime StartZeit = DateTime.Now;
Dispatcher.BeginInvoke(() =>
{
LblDuration.Text = "";

for (int i = 0; i < Pb1.Maximum/100; i++)
{
if ((worker.CancellationPending == true))
{

break;
}
else
{
for (int m = 0; m < 10; m++)
{

b = 2354.15; //double
c = (a * b) * (a * a * b);
}

Boolean Replacement

Hey Guys..
I have a problem with my xposed module.
I will a class to boolean false not true if rooted device..
Code:
public static boolean isRooted()
This to return false if rooted device..
Code:
XposedHelpers.findAndHockMethod("com.example.utils.RootCheck", lpparam.classLoader, "isRooted", boolean.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
param.args[0] = false;

Xposed say me nosuchmethoderror com.example.utils.RootCheck#isRooted(boolean)..
Can help me..
Thanks
Sorry for my bad English i m a german.

what class is it, is it your own?
are you filtering by package name?

Is not my own class..
From another Application..

This is the class. i have decoded.
I want replace "public static final String" , public static boolean isRooted() to ever false and private static boolean a(String str) to ever false..
can help me?
Code:
public final class RootCheck {
public static final String VALUE_DEVICE_FLAG_SU = "su";
public static final String VALUE_DEVICE_FLAG_SUPER_USER_APK = "superuser.apk";
public static final String VALUE_DEVICE_FLAG_TEST_KEYS = "testkeys";
private RootCheck() {
}
public static boolean isRooted() {
BuildConfig.IS_PROD.booleanValue();
return false;
}
public static Object[] getFlags() {
int i;
int i2;
List arrayList;
Object[] objArr;
int i3 = 1;
String str = Build.TAGS;
if (str == null || !str.contains("test-keys")) {
i = 0;
} else {
i = 1;
}
try {
if (new File("/system/app/Superuser.apk").exists()) {
i2 = 1;
if (!(a("/system/xbin/which su") || a("/system/bin/which su") || a("which su"))) {
i3 = 0;
}
arrayList = new ArrayList();
if (i3 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SU);
}
if (i2 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SUPER_USER_APK);
}
if (i != 0) {
arrayList.add(VALUE_DEVICE_FLAG_TEST_KEYS);
}
objArr = new Object[0];
if (arrayList.isEmpty()) {
return arrayList.toArray(objArr);
}
return objArr;
}
} catch (Exception e) {
}
i2 = 0;
i3 = 0;
arrayList = new ArrayList();
if (i3 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SU);
}
if (i2 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SUPER_USER_APK);
}
if (i != 0) {
arrayList.add(VALUE_DEVICE_FLAG_TEST_KEYS);
}
objArr = new Object[0];
if (arrayList.isEmpty()) {
return objArr;
}
return arrayList.toArray(objArr);
}
private static boolean a(String str) {
try {
Runtime.getRuntime().exec(str);
return true;
} catch (Exception e) {
return false;
}
}
}

oh wait, isRooted doesn't take any arguments and you're trying to hook isRooted with a boolean argument, which would be a different method
return values are called result here (getResult, setResult.) args is only for arguments

Oh thx

Code:
06-17 22:21:05.373: E/Xposed(30470): java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference
06-17 22:21:05.373: E/Xposed(30470): at de.bozja.hrh.Hidder$1.beforeHookedMethod(Hidder.java:22)
Error why?
class
Code:
findAndHookMethod("com.example.RootCheck", lpparam.classLoader, "isRooted", new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult(); //Error on this line
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult();
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
});

beforeHookedMethod is called before the method is executed, so there can't be any result. so it's null

Just setresult to false in beforehooked dont add extra junk
And dont hook method afterhook no need before will do what u need

i am also facing the same issue today when trying to hook some certain method that doesnt take in any argument. And i really didnt get the answer you gave. Could you be more elaborate please?

that was a long time. necrobumping from Google?
I think I meant to use param.setResult instead of param.args[0] to set the return value

this is the method i want to hook. I want it to return false
public boolean vpn() {
try {
Iterator it = Collections.list(NetworkInterface.getNetworkInterfaces()).iterator();
String str = "";
do {
if (!it.hasNext()) {
return false;
}
NetworkInterface networkInterface = (NetworkInterface) it.next();
if (networkInterface.isUp()) {
str = networkInterface.getName();
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("IFACE NAME: ");
stringBuilder.append(str);
Log.d("DEBUG", stringBuilder.toString());
if (str.contains("tun") || str.contains("ppp")) {
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
}
} while (!str.contains("pptp"));
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
return true;
} catch (SocketException e) {
e.printStackTrace();
}
}
and this is my kotlin class
package app.devzeus.yesvpn.hook
import de.robv.android.xposed.IXposedHookLoadPackage
import de.robv.android.xposed.XC_MethodHook
import de.robv.android.xposed.XposedHelpers
import de.robv.android.xposed.callbacks.XC_LoadPackage
class hook: IXposedHookLoadPackage {
override fun handleLoadPackage(lpparam: XC_LoadPackage.LoadPackageParam?) {
val pakage = "com.eclipse.gamonyapp"
val className = "com.eclipse.gamonyapp.Fragments.OffersFragment"
val method = "vpn"
if (lpparam?.packageName == pakage){
XposedHelpers.findAndHookMethod(className, lpparam.classLoader, method, object: XC_MethodHook(){
override fun beforeHookedMethod(param: MethodHookParam?) {
super.beforeHookedMethod(param)
param?.result = false
}
})
}
}
}
am i doing it wrong? it still doesnt work. The class and method locations are correct

this should be a separate thread imo
XC_MethodHook | Xposed Framework API
api.xposed.info
in Java there would be no need for the super call and the syntax is .setResult, but I'm not sure in Kotlin

about the .setResult(false) the compiler suggests .result = false
