Take a screenshot of your Android app and email it somewhere (no root access required)

gistfile1.java

  public static void sendFeedbackScreenshot(final Activity activity) {
    try {
      final View rootView = activity.getWindow().getDecorView().findViewById(android.R.id.content);
      rootView.setDrawingCacheEnabled(true);
      Bitmap bitmap = rootView.getDrawingCache();
      // Activity.getCacheDir() won't work here, because the email intent can't
      // access your app's internal storage. So you need to find a good temporary
      // location in SD card storage.
      File outputDir = new File(android.os.Environment.getExternalStorageDirectory(), "tmp");
      File outputFile = new File(outputDir, "screenshot.png");
      FileOutputStream fileOutputStream;
      fileOutputStream = new FileOutputStream(outputFile);
      bitmap.compress(Bitmap.CompressFormat.PNG, 100, fileOutputStream);
      rootView.setDrawingCacheEnabled(false);
      startEmailActivity(activity, Uri.fromFile(outputFile));
    }
    catch(Exception e) {
      // Show error message, etc.
    }
  }

  public static void startEmailActivity(Context context, Uri attachment) {
    Intent sendEmailIntent = new Intent(Intent.ACTION_SEND);
    sendEmailIntent.setType("message/rfc822");
    sendEmailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{TO_EMAIL_ADDRESS});
    sendEmailIntent.putExtra(Intent.EXTRA_SUBJECT, YOUR_EMAIL_SUBJECT);
    sendEmailIntent.putExtra(Intent.EXTRA_STREAM, attachment);
    context.startActivity(Intent.createChooser(sendEmailIntent, "Send email"));
  }

Sir, Thanks for posting this code. Can you share the complete android project code?
