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.

How do I set the Camera Intent as the Main Activity

I want to launch the camera once a user opens up my application.
Right now I have this, and it works fine. When the user launches my application, it automatically opens up the camera. However, then the user hits the "back" button after taking an image, it opens up a blank activity.
How do I get it to go back to the camera?
public class MainActivity extends AppCompatActivity {
private static final int REQUEST_TAKE_PHOTO = 0;
// The URI of photo taken with camera
private Uri mUriPhotoTaken;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
takePhoto();
}
// Deal with the result of selection of the photos and faces.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri imageUri;
if (data == null || data.getData() == null) {
imageUri = mUriPhotoTaken;
} else {
imageUri = data.getData();
}
Intent intent = new Intent(MainActivity.this, Result.class);
intent.setData(imageUri);
startActivity(intent);
}
}
// Launch the camera to allow the user to take a photo
public void takePhoto(){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(intent.resolveActivity(getPackageManager()) != null) {
// Save the photo taken to a temporary file.
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
try {
File file = File.createTempFile("IMG_", ".jpg", storageDir);
mUriPhotoTaken = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mUriPhotoTaken);
startActivityForResult(intent, REQUEST_TAKE_PHOTO);
} catch (IOException e) {
Log.d("ERROR", e.getMessage());
}
}
}
}

Try to call takePhoto() method in the onStart() instead of onCreate() and then call the finish() method into the onStop().

Try it.
#Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent(this, ActivityYouWantToOpen.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
finish();
}

java.net.MalformedURLException trying to retrieve a photo saved on my Android device

I am trying to add in my App a function to use the camera to store photos in my device.
At the beginning i use the camera like this:
mButtonCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
count++;
String file = dir+prova+".jpg";
File newFile = new File(file);
try {
newFile.createNewFile();
}catch (IOException e){}
Uri outputFileUri = Uri.fromFile(newFile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,outputFileUri);
Log.v("CameraDemo", "Pic savedNO");
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}
});
And then for the OnActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Log.v("CameraDemo", "Pic saved");
Log.v("Salva Foto", dir+prova+".jpg");
myDBHandler.addPhoto(prova,dir+prova+".jpg");
}
}
Until here evrything is ok but when I try to retrieve the photo using this:
InputStream URLcontent = null;
try {
URLcontent = (InputStream) new URL(fotoSI).getContent();
} catch (IOException e) {
e.printStackTrace();
}
Drawable image = Drawable.createFromStream(URLcontent, fotoSI);
mImageCamera.setImageDrawable(image);
It doesn´t return any photo that is what the Log says me:
java.net.MalformedURLException: Protocol not found: /storage/emulated/0/Pictures/
I am trying everything but without results.

create intent from thread

I need to create intent from thread:
final Runnable installapps = new Runnable() {
public void run() {
String[] fnames = appsPath.list();
for (String curfile : fnames) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)),
"application/vnd.android.package-archive");
startActivity(intent);
}
}
};
I tried using runOnUiThread but it's still cant be done (app crashed).
Thanks

You need to start the new Intent from within an Activity class. Then simply invoke:
Intent intent = new Intent(this);

Made it with a handler and StartActivityForResult(). It starts installation Intent, waits for any result (just closing of intent), and executes next one.
handler.sendEmptyMessage(0);
private Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
appcounter++;
if (appcounter < fnames.length) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(appsPath + "/" + fnames[appcounter])), "application/vnd.android.package-archive");
startActivityForResult(intent, req);
}
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("CheckStartActivity","onActivityResult and resultCode = "+resultCode);
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
// appcounter++;
handler.sendEmptyMessage(0);
}

capturing image using camera in Android

Hi stackoverflow friends,
I need to take a picture using camera and after takin the picture go to next activity without showing the first activity. And display it in an imageview.
Below is the flow of my application
first activity-> there is button for camera intent->go to the next activity(without showing the fist activity) second activity->there i need to show the image in imageview.
I saw a lot of examples of camera intent nobody explains how to go to the next activity without showing the first and display it in imageview of second.
Any outofmemeory problem occurs while displaying images in imageview repeatedly?
Thanks in advance

In First activity :
Button b=(Button)findViewByid(R.id.button);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
doTakePhotoAction();
}
});
private void doTakePhotoAction() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"pic_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, CAMERA_RESULT);
// finish();
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == CAMERA_RESULT) {
Intent intent = new Intent(this, nextimage.class);
// here you have to pass absolute path to your file
intent.putExtra("image-path", mUri.getPath());
intent.putExtra("scale", true);
startActivity(intent);
finish();
}
}
In nextimage.class you can set one image view and get the imagepath from putExtra and place it in imageview.
String mImagePath = extras.getString("image-path");
Bitmap mBitmap = getBitmap(mImagePath);
private Uri getImageUri(String path) {
return Uri.fromFile(new File(path));
}
private Bitmap getBitmap(String path) {
Uri uri = getImageUri(path);
InputStream in = null;
try {
in = mContentResolver.openInputStream(uri);
return BitmapFactory.decodeStream(in);
} catch (FileNotFoundException e) {
Log.e(TAG, "file " + path + " not found");
}
return null;
}
place the bitmap in the imageview.you have to create imageview in secondActivity.

use a camera intent....here's a simple code
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.widget.ImageView;
public class CameraIntent extends Activity {
final static int CAMERA_RESULT = 0;
ImageView imv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_RESULT);
}
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK)
{
Get Bundle extras = intent.getExtras();
Bitmap bmp = (Bitmap) extras.get("data");
imv = (ImageView) findViewById(R.id.ReturnedImageView);
imv.setImageBitmap(bmp);
}
}
}

Use Following Code for that, it will solve your problem.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
onActivityResult() Method:-
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_PIC_REQUEST) {
bmpImage = (Bitmap) data.getExtras().get("data");
drawable = new BitmapDrawable(bmpImage);
mImageview.setImageDrawable(drawable);
}
}
}
