Set Wallpaper in whatsapp after getting the path

Question

I am following this answer to accomplish my task. Everything works well except the last part,

if(result!=null)
{

    Toast.makeText(getApplicationContext(), "Image saved in Gallery !", Toast.LENGTH_LONG).show();

    if(isinint) //check if any app cares for the result
    {
        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND, Uri.fromFile(new File(result.toString()))); //Create a new intent. First parameter means that you want to send the file. The second parameter is the URI pointing to a file on the sd card. (openprev has the datatype File)

        ((Activity) ImageListActivity.this).setResult(Activity.RESULT_OK, shareIntent); //set the file/intent as result
        ((Activity) ImageListActivity.this).finish(); //close your application and get back to the requesting application like GMail and WhatsApp
        return; //do not execute code below, not important
    }
}

At last nothing crash but wallpaper is also not set in whatsapp.

Can anyone please let me know why it is not working?

Any help is appriciated.

Thanks

Where do you set isinint? Did you debug the code and checked at what point it stops working? Please edit your question and give more informations. — James Cameron, Mar 21 '15 at 11:45
@JamesCameron Yes, I already debug it, it executes all the lines, no error & then I go to whatsapp chat where wallpaper doesnt set — Vivek Warde, Mar 30 '15 at 03:09
Found an answer yet? I imagine that the ACTION_SEND Intent may be wrong as it may be called with another intention. Please debug the Intent you get when the app is called. — James Cameron, Jul 15 '15 at 13:16

You can use the following code..

OnButtonClick(){
ImageProcessing imageProcessing = new ImageProcessing();
            Bitmap bitmap = imageProcessing.takeScreenshot(getWindow().getDecorView().findViewById(R.id.view_thought));
            imageProcessing.saveBitmap(bitmap);
            Intent intent = imageProcessing.setAsOption(this,imageProcessing.getSavedImagePath());
            startActivityForResult(Intent.createChooser(intent, "Set image as"), 200);
}

And Implement a new class ImageProcessing

public class ImageProcessing {
private File imagesPath;
public void saveBitmap(Bitmap bitmap) {
    imagesPath = new File(Environment.getExternalStorageDirectory() + "/screenshot.jpg");
    FileOutputStream fos;
    try {
        fos = new FileOutputStream(imagesPath);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        Log.e("POS", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("POS", e.getMessage(), e);
    }
}
public File getSavedImagePath(){
    imagesPath = new File(Environment.getExternalStorageDirectory() + "/screenshot.jpg");
    return imagesPath;
}

public Bitmap takeScreenshot(View rootView) {
    rootView.setDrawingCacheEnabled(true);
    return rootView.getDrawingCache();
}
public Intent setAsOption(Context cntxt,File imagesPath){
    /*File imagesPath = new File(Environment.getExternalStorageDirectory() + "/screenshot.jpg");*/
    Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
    if(imagesPath.exists()){
        Uri contentUri = FileProvider.getUriForFile(cntxt, BuildConfig.APPLICATION_ID+".Utility.GenericFileProvider",imagesPath);

        intent.setDataAndType(contentUri, "image/jpg");
        intent.putExtra("mimeType", "image/jpg");
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    }else {
        Toast.makeText(cntxt,"Not a wallpaper",Toast.LENGTH_SHORT).show();
    }
    return intent;
}

}

And in menifest add :

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.SET_WALLPAPER" />
