Play a success sound ONLY when Activity is complete

I have created an app that you could share images with them. I have set a notification sound when the sharing process is done. However, if I hit Cancel/Back buttons, the sound still plays.
In my code below, I have set a share button, once you click on it, you can share a bitmap of the image through the basic sharing app of android.
How can I set the sound to ONLY play when the sharing is complete.
Thanks,
Safi
Here's my code:
shareBtn = findViewById(R.id.shareButton);
shareBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.startAnimation(animTranslate);
shareDigitalCard();
}
});
private void shareDigitalCard() {
if (ActivityCompat.checkSelfPermission(MyMenu.this,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
try {
makeStorageRequest();
} catch (Exception e) {
e.printStackTrace();
}
}else {
Bitmap viewBmp = Bitmap.createBitmap(mPager.getWidth(),
mPager.getHeight(), Bitmap.Config.ARGB_8888);
viewBmp.setDensity(mPager.getResources().getDisplayMetrics().densityDpi);
Canvas canvas = new Canvas(viewBmp);
//mPager.layout(0, 0 , mPager.getLayoutParams().width, mPager.getLayoutParams().height);
mPager.draw(canvas);
path = String.valueOf(saveTempBitmap(viewBmp));
shareImage(path);
}
}
private void shareImage(String file) {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Intent share = new Intent(Intent.ACTION_SEND);
// If you want to share a png image only, you can do:
// setType("image/png"); OR for jpeg: setType("image/jpeg");
share.setType("image/*");
File imageFileToShare = new File(file);
Uri uri = Uri.fromFile(imageFileToShare);
share.putExtra(Intent.EXTRA_STREAM, uri);
try {
startActivityForResult(Intent.createChooser(share, "Share Image!"),123);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 123){
if (isSoundEnable) {
MediaPlayer player = null;
if (player == null) {
player = MediaPlayer.create(this, R.raw.success);
final MediaPlayer finalPlayer = player;
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
stopPlayer(finalPlayer);
}
});
}
player.start();
}
} else {
Toast.makeText(this, "An Error Has Occured !", Toast.LENGTH_SHORT).show();
}
}

You cannot get this event. The sharing procedure depends on the other App and you haven't any control or result from it. What you know is just you have send an Intent to a specific App, but what it does it's all up to it.

Qr code scan from gallery but just scanned qr with black and white color

I have project, I make scan Qr code from gallery image. it works fine. But my problem is my app scanned only qr with black and white color. when I trying to add others qr image with blue and white, it can't read.
This is my code
//call the onactivity result method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch (requestCode) {
case SELECT_PHOTO:
if (resultCode == RESULT_OK) {
//doing some uri parsing
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream = null;
try {
//getting the image
imageStream = getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
Toast.makeText(getApplicationContext(), "File not found", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
//decoding bitmap
Bitmap bMap = BitmapFactory.decodeStream(imageStream);

//copy pixel data from the Bitmap into the 'intArray' array
bMap.getPixels(intArray, 0, bMap.getWidth(), 0, 0, bMap.getWidth(), bMap.getHeight());

making submit button clickable and not clickable

im trying to have my apps submit button not clickable until the user takes a picture. so initially the button will be not clickable and then when the person takes a picture the submit button becomes clickable so they can move on. problem is i cant get it to work properly. as of right now the submit button is not clickable (which is what i want) when it first loads. but if i hit the camera button then press the back button the submit button becomes visible(i want it to be unclickable). how can i correct this so that it doesnt show the submit button during this situation? o far i have tried to set not clickable in the oncreate method , and i set to clickable when the image file is made in the photobutton. which didnt work.

move this line
btnSubmit.setEnabled(true);
to onActivityResult() method after this line
imageView.setImageBitmap(photo);

your code looks fine but i think it would look better if you just played with the visibility of the button:
btnSubmit.setVisibility(View.GONE);
btnSubmit.setVisibility(View.VISIBLE);
and you have to to add :
btnSubmit.setEnabled(true);
into your onActivityResult() method

Take the screenshot at a time to be display the image to image viewer app

I have screenshot button and when i take screenshot, image should be stored in the sd card and when i going to see the gallery they display the image.
But, I want to when i take screenshot at a time, to be display in the image viewer app.

Button captureImage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
captureImage = (Button)findViewById(R.id.captureImage);
captureImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Bitmap bitmap = takeScreenshot();
saveBitmap(bitmap);
}
private void saveBitmap(Bitmap bitmap) {
// TODO Auto-generated method stub
File imagePath = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/"+"MyProfile.JPEG");
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(imagePath)));
FileOutputStream fos;
try {

bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
Toast.makeText(getApplicationContext(), "Screen short saved", Toast.LENGTH_SHORT).show();

Store the taken picture from ImageView to the phone storage

After I take a picture I store the picture into ImageView, So if anyone has an idea or suggestion in how to store the picture after it shown on the ImageView into phone stage without user interaction
Thanks in advance
public class MainActivity extends Activity {
ImageView viewpict;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpict=(ImageView) findViewById(R.id.pict_result);
Button btn= (Button)findViewById(R.id.camera);
btn.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0) {
Intent intent = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
// Intent intent = new Intent (getApplicationContext(),MainActivity2.class);
//startActivity(intent);
startActivityForResult(intent,0);
}
});
}
protected void onActivityResult( int requestCode, int resultCode,Intent data)
{
if (requestCode==0)
{
Bitmap theimage = (Bitmap) data.getExtras().get("data");
viewpict.setImageBitmap(theimage);
}
}
}

Try:
viewpict.buildDrawingCache();
Bitmap bm=viewpict.getDrawingCache();
And save:
OutputStream fOut = null;
Uri outputFileUri;
try {
File root = new File(Environment.getExternalStorageDirectory()
+ File.separator + "folder_name" + File.separator);
root.mkdirs();
File sdImageMainDirectory = new File(root, "myPicName.jpg");
outputFileUri = Uri.fromFile(sdImageMainDirectory);
fOut = new FileOutputStream(sdImageMainDirectory);
} catch (Exception e) {
Toast.makeText(this, "Error occured. Please try again later.",
Toast.LENGTH_SHORT).show();
}
try {
bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
} catch (Exception e) {
}
And permission in AndroidManifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
