Good afternoon, in my application I shoot video with a mobile camera, then I launch this video thanks

@Override

public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height)

{

    Surface s = new Surface(surface);



    try

    {

        mp = new MediaPlayer();

        mp.setDataSource(getVideoFilePath());

        mp.setSurface(s);

        mp.prepare();



        mp.setOnBufferingUpdateListener(this);

        mp.setOnCompletionListener(this);

        mp.setOnPreparedListener(this);

        mp.setOnVideoSizeChangedListener(this);



        mp.setAudioStreamType(AudioManager.STREAM_MUSIC);

        setPreviewSize(true);

        mp.start();

    }

    catch (IllegalArgumentException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

    } catch (SecurityException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

    } catch (IllegalStateException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

    } catch (IOException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

    }

}

I implemented a method that takes a screenshot and saves it to the gallery,

  public void getBitmap(TextureView vv)

{

    String mPath = getAndroidImageFolder().getAbsolutePath() + "/" + new SimpleDateFormat("yyyyMM_dd-HHmmss").format(new Date()) + "cameraRecorder.png";

    Toast.makeText(getApplicationContext(), "Capturing Screenshot: " + mPath, Toast.LENGTH_SHORT).show();



    Bitmap bm = vv.getBitmap();

    if(bm == null)

        Log.e(TAG,"bitmap is null");



    OutputStream fout = null;

    File imageFile = new File(mPath);



    try {

        fout = new FileOutputStream(imageFile);

        bm.compress(Bitmap.CompressFormat.PNG, 90, fout);

        fout.flush();

        fout.close();

    } catch (FileNotFoundException e) {

        Log.e(TAG, "FileNotFoundException");

        e.printStackTrace();

    } catch (IOException e) {

        Log.e(TAG, "IOException");

        e.printStackTrace();

    }

}

But the screenshot does not appear in the gallery and knocks out an error.
That's what produces in Logcat

 E/TextureViewActivity: FileNotFoundException

Here on what part of the code knocks an error

at com.camera.VideoProcessor.getBitmap(VideoProcessor.java:247)  ->  fout = new FileOutputStream(imageFile);

I would be very grateful for your help)

It sounds like you don't have the right permissions.

Add <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> to AndroidManifest.xml if it isn't already there.
