INTENT.ACTION_VIDEO_CAPTURE does not save file in user location Uri

I created such an application. The button has a button, when you click the button, video capture starts.

I now have this code for this: -

public class VideoCaptureComponentActivity extends Activity implements View.OnClickListener { VideoView vv; ImageButton ib; TextView tv; Intent i; final static int cameraData=0; File path = null; Uri myVideo; private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200; private Uri fileUri; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); vv= (VideoView) findViewById(R.id.vvVideoCapture); ib=(ImageButton) findViewById(R.id.btnVideo); ib.setOnClickListener(this); tv= (TextView) findViewById(R.id.tvFilePath); } @Override public void onClick(View v) { switch(v.getId()) { case R.id.btnVideo: Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); fileUri = getOutputMediaFileUri(); // create a file to save the video intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0); // set the video image quality to high // start the Video Capture Intent startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE); break; } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) { if (resultCode == RESULT_OK) { myVideo= data.getData(); tv.setText(myVideo.toString()); vv.setVideoURI(myVideo); vv.setMediaController(new MediaController(this)); vv.requestFocus(); vv.start(); } } } /** Create a file Uri for saving an image or video */ private static Uri getOutputMediaFileUri() { return Uri.fromFile(getOutputMediaFile()); } /** Create a File for saving an image or video */ private static File getOutputMediaFile() { File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES), "MyCameraApp"); if (! mediaStorageDir.exists()){ if (! mediaStorageDir.mkdirs()){ Log.d("MyCameraApp", "failed to create directory"); return null; } } File mediaFile; mediaFile = new File(mediaStorageDir.getPath() + File.separator + "VID_CAPTURED" + ".mp4"); return mediaFile; } }

Now after I captured the video, the application crashes.

basically the problem is that in the code

 Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); fileUri = getOutputMediaFileUri(); intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);

here it doesn’t save the file in the set location, I don’t know what the problem is. I took this code from this link http://developer.android.com/guide/topics/media/camera.html

No, if you pass Uri to save an image or video using putExtra(MediaStore.EXTRA_OUTPUT, fileUri); , then you always get data.getData(); in onActivityResult as NULL . therefore, use Uri images or videos transmitted with the intention, such as:

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) { if (resultCode == RESULT_OK) { // myVideo= data.getData(); tv.setText("Video"); vv.setVideoURI(fileUri);//set Uri here which you passed with Intent vv.setMediaController(new MediaController(this)); vv.requestFocus(); vv.start(); } } }

delete aim.putExtra (MediaStore.EXTRA_OUTPUT, fileUri); from intention

I use this code to record and save videos:

 private String name_vid; private static int REC_VIDEO = 1; public void rec_vid(View v) { //set name & path to vid name_vid = Environment.getExternalStorageDirectory()+"/videos/myvid.mp4"; //check if folder exists, else, create it File path = new File(Environment.getExternalStorageDirectory()+"/videos/"); if (!path.exists()) path.mkdirs(); //create the intent Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); int code = REC_VIDEO; Uri output = Uri.fromFile(new File(name_vid)); //Add extra to save video intent.putExtra(MediaStore.EXTRA_OUTPUT, output); startActivityForResult(intent, code); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == REC_VIDEO) { if (resultCode == -1) { //create a MediaScanner to save the vid into the indicate path new MediaScannerConnectionClient() { private MediaScannerConnection msc = null; { msc = new MediaScannerConnection( getApplicationContext(), this); msc.connect(); } public void onMediaScannerConnected() { msc.scanFile(name_vid, null); } public void onScanCompleted(String path, Uri uri) { msc.disconnect(); } }; Toast.makeText(this,"Video saved succesfull", Toast.LENGTH_SHORT).show(); } } }

Remember that you need to set the use of permissions in the manifest:

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