android android.provider.MediaStore.ACTION_VIDEO_CAPTURE return null onActivityResult with nexus 7

Question

I am using intent for record video.

so i use following code on recordVideo button's click

Videofilepath = "";
Intent intent = new Intent(android.provider.MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(intent,REQUEST_VIDEO_CAPTURED);

and in onActivityResult

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (resultCode == Activity.RESULT_OK) {
            switch (requestCode) {
            case IMAGE_PICK:
                this.imageFromGallery(resultCode, data);
                break;
            case IMAGE_CAPTURE:
                this.imageFromCamera(resultCode, data);
                break;
            case REQUEST_VIDEO_CAPTURED:
                this.videoFromCamera(resultCode, data);

                break;
            default:
                break;
            }
        }
    }


private void videoFromCamera(int resultCode, Intent data) {
        uriVideo = data.getData();


        uploadedFileName="";
        Constant.IS_FILE_ATTACH = true;

        Toast.makeText(PDFActivity.this, uriVideo.getPath(), Toast.LENGTH_LONG)
        .show();
        String[] filePathColumn = { MediaStore.Video.Media.DATA };

        Cursor cursor = getContentResolver().query(uriVideo, filePathColumn,
                null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String filePath = cursor.getString(columnIndex);
        Videofilepath = filePath;
        System.out.println("Videofilepath filepath from camera : "
                + Videofilepath);
        cursor.close();
        File f = new File(filePath);
        System.out.println("file created ? : " + f.exists());

        Bitmap bMap = null;
        do {
            try {
                // Simulate network access.
                Thread.sleep(3000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        } while (!f.exists());
        bMap = ThumbnailUtils.createVideoThumbnail(filePath,
                MediaStore.Video.Thumbnails.MICRO_KIND);
        do {
            try {
                // Simulate network access.
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        } while (bMap == null);
        imageOrVideo = "video";
        attachmentvalue.setImageBitmap(bMap);
    }

This code is working fine with samsung galaxy Tab. But not working with Nexus 7. May be Nexus 7 have front camera. but i got resultant data intent is null onActivityResult.

so in my Logcat i got the following exception :-

08-08 12:51:31.160: E/AndroidRuntime(10899): FATAL EXCEPTION: main
08-08 12:51:31.160: E/AndroidRuntime(10899): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=200, result=-1, data=Intent {  }} to activity {com.example.activity/com.example.PDFActivity}: java.lang.NullPointerException

Answer 1

Finally I resolved this issue. Nexus 7 Stores the videos in DCIM directory but onActivityResults it returns null. Its an documented issue with Nexus 7 device.

so fix this issue with intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
the code is as :-

code on record button click:-

  intent = new Intent(android.provider.MediaStore.ACTION_VIDEO_CAPTURE);    
   fileUri = getOutputMediaFile(MEDIA_TYPE_VIDEO);  // create a file to save the video in specific folder (this works for video only)
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high

    // start the Video Capture Intent
    startActivityForResult(intent, REQUEST_VIDEO_CAPTURED_NEXUS);

code inside switch - case block of onActivityResult :-

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (resultCode == Activity.RESULT_OK) {
            switch (requestCode) {
    case REQUEST_VIDEO_CAPTURED_NEXUS:
    this.videoFromCameraNexus(resultCode, data);
    break;

default:
                break;
            }
        }
    }

// videoFromCameraNexus method

private void videoFromCameraNexus(int resultCode, Intent data) {

        if(fileUri != null) {
            Log.d(TAG, "Video saved to:\n" + fileUri);
            Log.d(TAG, "Video path:\n" + fileUri.getPath());
            Log.d(TAG, "Video name:\n" + getName(fileUri)); 
    // use uri.getLastPathSegment() if store in folder
    //use the file Uri.
        }
    }

Get the output Media file uri with the following Method

public Uri getOutputMediaFile(int type)
    {
        // To be safe, you should check that the SDCard is mounted

        if(Environment.getExternalStorageState() != null) {
            // this works for Android 2.2 and above
            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES), "SMW_VIDEO");

            // This location works best if you want the created images to be shared
            // between applications and persist after your app has been uninstalled.

            // Create the storage directory if it does not exist
            if (! mediaStorageDir.exists()) {
                if (! mediaStorageDir.mkdirs()) {
                    Log.d(TAG, "failed to create directory");
                    return null;
                }
            }

            // Create a media file name
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            File mediaFile;
           if(type == MEDIA_TYPE_VIDEO) {
                mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                "VID_"+ timeStamp + ".mp4");
            } else {
                return null;
            }

            return Uri.fromFile(mediaFile);
        }

        return null;
    }

Its works for me.

Answer 2

Thanks for the workaround!

Here is more brushed and copy-paste usable code:

/**
 * Create intent to take video.
 */
public static Intent createTakeVideoIntent() {
    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    Uri uri = getOutputVideoUri();  // create a file to save the video in specific folder
    if (uri != null) {
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
    }
    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high

    return intent;
}


@CheckForNull
private static Uri getOutputVideoUri() {
    if (Environment.getExternalStorageState() == null) {
        return null;
    }

    File mediaStorage = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "YOUR_APP_VIDEO");
    if (!mediaStorage.exists() &&
            !mediaStorage.mkdirs()) {
        Log.e(YourApplication.TAG, "failed to create directory: " + mediaStorage);
        return null;
    }

    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(new Date());
    File mediaFile = new File(mediaStorage, "VID_" + timeStamp + ".mp4");
    return Uri.fromFile(mediaFile);
}
