In my application when I get position latitude and longitude from GPS, I am downloading bing map to a picture box. I've been trying now to protect my application in case there is no internet connection. I've done that in the GetMap function and it works fine. After that I want to close gps - the problem is that I'm trying to do that in gps event handler - it is so because I update the picture box constantly:
Code:
void UpdateData(object sender, System.EventArgs args)
{
menuGPS.Text = "Enable GPS";
menuZoom.Enabled = false;
menuView.Enabled = false;
}
void gps_LocationChanged(object sender, Microsoft.WindowsMobile.Samples.Location.LocationChangedEventArgs args)
{
if (args.Position.LatitudeValid && args.Position.LongitudeValid)
{
if (isCameraEnabled == false)
{
try
{
pbMap.Invoke((UpdateMap)delegate()
{
pbMap.Image = bingMap.GetMap(args.Position.Latitude,
args.Position.Longitude,
zoom,
mapStyle);
});
if (pbMap.Image == null)
{
Invoke(updateDataHandler);
gpsData.gps.LocationChanged -= gps_LocationChanged;
gpsData.closeGPS();
}
}
catch (ArgumentException ex)
{
MessageBox.Show("An error has occured:" + ex.Message , "Error");
}
}
else
{
}
}
}
So after the gpsData.gps.LocationChanged -= gps_LocationChanged; and gpsData.closeGPS(); are being called in the event handler the gps gets stuck in the WaitForGpsEvents() method in GPS.cs in the while loop because bool lisening value is not changed to false.
If I put gpsData.gps.LocationChanged -= gps_LocationChanged; and gpsData.closeGPS(); to the void UpdateData(object sender, System.EventArgs args) then it stops in the Close() method on the lock condition:
// block until our event thread is finished before
// we close our native event handles
lock (this)
How can I close the GPS?
hello guys and girls,
I have a very peculiar problem with my application (two actually, working together to make a bigger problem)
I have a resume tile, which allows the users to resume working on the picture they were working after navigating away from the game.
Now, the users can choose pictures in their media lib to use in the game.
However, after i sync my phone to laptop, unplug it, then try to use the resume tile, it simply brings me to main page and does not continue doing the resume as it should do. This only happens with pictures from photochooser task: the ones integrated in the app work fine.
The photochooser task also refuses to work properly until i start the app "the usual way" and not from the resume tile. It basically goes back to the MainPage no matter what.
So, what's with all this? I think it has something to do with the syncing messing up isolated storage and phone storage.
here's some code:
MainPage:
Basically, I'm using some messages to know from where i navigated to the MainPage. The "resumeTile" message is obviously coming from the resume tile, whereas "FromPlay" means the player just left the play page.
App.IsFirstLoaded is used to known that it loaded already and should ignore the "ResumeTile" message and continue with the resume, but not to repeat the same feat in case the user navigates from any page in the game.
Code:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
string msesage = null;
try
{
NavigationContext.QueryString.TryGetValue("message", out msesage);
if (msesage == "resumeTile")
{
App.isFirstLoaded = true;
}
if (msesage == "FromPlay")
{
NavigationService.RemoveBackEntry();
}
if (App.isFirstLoaded == true)
{
resume_SubmitResume();
App.isFirstLoaded = false;
msesage = null;
}
else
{
//NavigationService.RemoveBackEntry();
base.OnNavigatedTo(e);
if (msg == "openPlay")
{
string msggs = msg;
msg = null;
if (portrait)
{
NavigationService.Navigate(new Uri("/PlayPage.xaml?msg=" + msggs, UriKind.Relative));
}
else
{
NavigationService.Navigate(new Uri("/PlayPageLandscape.xaml?msg=" + msggs, UriKind.Relative));
}
}
}
}
catch (NullReferenceException)
{
}
}
and here is the photochooser task completed event handler
Code:
void photochoser_Completed(object sender, PhotoResult e)
{
string path = "mhgcjtcthgg.jpg";
if (e.TaskResult == TaskResult.OK)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream fs = new IsolatedStorageFileStream(path, FileMode.Create, FileAccess.Write, FileShare.ReadWrite, IsolatedStorageFile.GetUserStoreForApplication()))
{
if (e.Error == null)
{
if (App.AutoSave == true)
{
MediaLibrary ml = new MediaLibrary();
ml.SavePicture("CountlessPuzzles" + DateTime.Now.ToShortTimeString(), e.ChosenPhoto);
}
BitmapImage bi = new BitmapImage();
bi.SetSource(e.ChosenPhoto);
WriteableBitmap wb = new WriteableBitmap(bi);
if (wb.PixelHeight <= wb.PixelWidth)
{
Extensions.SaveJpeg(wb, fs, DHeigh, DWidth, 0, 100);
//NavigationService.Navigate(new Uri("/PlayPageLandscape.xaml?msg=" + msg, UriKind.Relative));
}
else
{
Extensions.SaveJpeg(wb, fs, DWidth, DHeigh, 0, 100);
//NavigationService.Navigate(new Uri("PlayPage.xaml?msg=" + msg, UriKind.Relative));
portrait = true;
}
}
}
}
msg = "openPlay";
}
else
{
isDataSavedInIsolatedStorage = false;
}
// e.ChosenPhoto.Close();
}
So, any ideas?

Photochooser does not work when the phone is syncing via zune, maybe once the app is running and you try to sync, PhotoChooser crashes or something.
http://www.codeproject.com/Articles/342149/Using-WPConnect-instead-of-Zune-for-Windows-Phone
I figured that when synced, the photochooser instantiated inside the app is turned off or something, and stays so until the constructor is called again, which would happen if the app is re-launched.
Kinda peculiar though...
Does anyone know where I can find code handling the current live wallpaper engine / view? I am trying to extract the live wallpaper for further processing (e.g. blurring).
I already found an entrance point: If the LWP used the standard com.android.internal.view.BaseSurfaceHolder supplied by the base class android.service.wallpaper.WallpaperService.Engine i can hook into lockCanvas and unlockCanvas to grab the image. But most LWPs do not use this, so I need another (more general) solution.
I thought about hooking all subclasses of android.service.wallpaper.WallpaperService, but AFAIK that's not possible without loading every single class and check if it's a subclass.
Any ideas?
Implementation for reference:
Code:
public class Hook implements IXposedHookLoadPackage {
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
final Class<?> engingeClass = findClass("android.service.wallpaper.WallpaperService.Engine", loadPackageParam.classLoader);
final String packageName = loadPackageParam.packageName;
final Class<?> surfaceHolderClass = findClass("com.android.internal.view.BaseSurfaceHolder",loadPackageParam.classLoader);
findAndHookMethod(engingeClass, "getSurfaceHolder", new XC_MethodHook() {
private boolean isFirstCall = true;
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
Field field = findField(param.thisObject.getClass(), "this$0");
WallpaperService service = (WallpaperService) field.get(param.thisObject);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(service);
if (isFirstCall && wallpaperManager.getWallpaperInfo().getPackageName().equals(packageName)) {
isFirstCall = false;
XposedBridge.log("Got context. Set up hooks...");
hook(surfaceHolderClass,service);
}
}
});
}
Bitmap bitmap;
Canvas internalCanvas;
Canvas originalCanvas;
private void hook(Class<?> clazz, final Context context) {
hookAllMethods(clazz, "lockCanvas", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
originalCanvas = (Canvas) param.getResult();
bitmap = Bitmap.createBitmap(originalCanvas.getWidth(),originalCanvas.getHeight(), Bitmap.Config.ARGB_8888);
internalCanvas = new Canvas(bitmap);
param.setResult(internalCanvas);
XposedBridge.log("Locked Canvas");
}
});
findAndHookMethod(clazz, "unlockCanvasAndPost", Canvas.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
originalCanvas.drawBitmap(bitmap,0,0,null);
param.args[0] = originalCanvas;
Intent intent = new Intent("com.faendir.lwpextractor.WALLPAPER_CHANGE");
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG,100,bs);
intent.putExtra("bmp",bs.toByteArray());
context.sendBroadcast(intent, "com.faendir.lwpextractor.RECEIVE_WALLPAPER_CHANGE");
XposedBridge.log("Unlocked Canvas");
}
});
}
}

So, I'm getting fairly good at hooking and modifying classes, but this one is so unique, I'm not quite sure how to approach hooking it to do what I want. Code for the method/class I want to attack:
Code:
private class CreateLaunchPointListTask
extends AsyncTask<Void, Void, List<LaunchPoint>>
{
private CreateLaunchPointListTask() {}
protected List<LaunchPoint> doInBackground(Void... paramVarArgs)
{
paramVarArgs = mContext.getString(2131558445);
Object localObject = new Intent("android.intent.action.MAIN");
((Intent)localObject).addCategory(paramVarArgs);
paramVarArgs = new LinkedList();
PackageManager localPackageManager = mContext.getPackageManager();
localObject = localPackageManager.queryIntentActivities((Intent)localObject, 129);
int j = ((List)localObject).size();
int i = 0;
while (i < j)
{
ResolveInfo localResolveInfo = (ResolveInfo)((List)localObject).get(i);
if (activityInfo != null) {
paramVarArgs.add(new LaunchPoint(mContext, localPackageManager, localResolveInfo));
}
i += 1;
}
return paramVarArgs;
}
public void onPostExecute(List<LaunchPoint> arg1)
{
synchronized (mLock)
{
mAllLaunchPoints.clear();
mAllLaunchPoints.addAll(???);
synchronized (mCachedActions)
{
LaunchPointListGenerator.access$502(LaunchPointListGenerator.this, true);
if (!mCachedActions.isEmpty()) {
((LaunchPointListGenerator.CachedAction)mCachedActions.remove()).apply();
}
}
}
LaunchPointListGenerator.access$602(LaunchPointListGenerator.this, true);
Iterator localIterator = mListeners.iterator();
while (localIterator.hasNext()) {
((LaunchPointListGenerator.Listener)localIterator.next()).onLaunchPointListGeneratorReady();
}
}
}
So, while this is a big chunk of code, everything I want to do is really in the first few lines:
Code:
paramVarArgs = mContext.getString(2131558445);
Object localObject = new Intent("android.intent.action.MAIN");
((Intent)localObject).addCategory(paramVarArgs);
So, string 2131558445 is a specific intent. What I would like to do is add *another* category after 2131558445 is added to localObject.
That would be the simplest implementation.
A more advanced implementation would be to actually and return a second LinkedList, paramVarArgs2, that only matches up to the second intent category that we're inserting.
Any help would be greatly appreciated.
Hello, I have made this code
Link : http://hastebin.com/hiyupafibi.java
Duplicated here :
Code:
//In my module, I have this activity MainActivity, which has a function to generate random number
private int randomNumber() {
return (new Random()).nextInt(3);
}
//Toast this random number somewhere in the main activity
Toast.makeText(MainActivity.this, " " + randomNumber(), Toast.LENGTH_LONG).show();
//In XposedMod, make a hook
public class XposedMod implements IXposedHookLoadPackage {
private TextView tv;
public static final String PACKAGE_NAME = ".......";
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
if (lpparam.packageName.equals(PACKAGE_NAME)) {
Class<?> MainActivityClass = XposedHelpers.findClass(PACKAGE_NAME + ".MainActivity", lpparam.classLoader);
XposedHelpers.findAndHookMethod(MainActivityClass, "randomNumber", new XC_MethodReplacement() {
@Override
protected Object replaceHookedMethod(MethodHookParam methodHookParam) throws Throwable {
try {
tv.setText("No NPE");
return 45;
} catch (NullPointerException e) {
return 44;
}
}
});
} else if (lpparam.packageName.equals("com.android.systemui")) {
Class<?> someClass = XposedHelpers.findClass("com.android.systemui.SomeClass", lpparam.classLoader);
XposedHelpers.findAndHookMethod(someClass, "someMethod", Context.class, new XC_MethodHook() {
@Override
protected Object beforeHookedMethod(MethodHookParam methodHookParam) throws Throwable {
tv = new TextView((Context) param.args[0]);
if (tv==null)
XposedBridge.log("tv is null, apologies!");
}
});
}
}
}
Everytime that toast is supposed to be shown, I get the answer to be 44 (that is, tv is null), but that should not be the case, because the log statement when tv is null is not shown. What am I doing wrong?
Thanks for the help, I appreciate it.
Cheers!
