Android - Picker to select multiple videos

Question

I've tried using a simple Activity to select multiple videos, but the file paths I get are always null. Even though I get the URI like :

"content://com.android.providers.media.documents/document/video%3A86935"

I cannot convert this into a filePath. With the code below, "videoPath is null" will be always printed.

public class VideoPickerActivity extends Activity {

    private static final String TAG = "VideoPickerActivity";

    private static final int SELECT_VIDEO = 1;

    private List<String> selectedVideos;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent();
        intent.setType("video/mp4");
        intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select videos"), SELECT_VIDEO);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_VIDEO) {
                selectedVideos = getSelectedVideos(data);
            }
        }
        finish();
    }

    private List<String> getSelectedVideos(Intent data) {

        List<String> result = new ArrayList<>();

        String[] filePathColumn = { MediaStore.Video.Media.DATA };

        // Single video selected
        if(data.getData() != null){

            Uri mImageUri = data.getData();

            // Get the cursor
            Cursor cursor = getContentResolver().query(mImageUri,
                    filePathColumn, null, null, null);
            // Move to first row
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String videoPath  = cursor.getString(columnIndex);
            if(videoPath == null)
                Log.e(TAG, "videoPath is null");
            result.add(videoPath);
            cursor.close();
        }
        // Multiple videos selected
        else {
            ClipData mClipData = data.getClipData();
            if (mClipData != null) {
                for (int i = 0; i < mClipData.getItemCount(); i++) {

                    ClipData.Item item = mClipData.getItemAt(i);
                    Uri uri = item.getUri();
                    // Get the cursor
                    Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
                    // Move to first row
                    if (cursor == null)
                        Log.e(TAG, "cursor is null");
                    else {
                        if (cursor.moveToFirst()) {
                            int columnIndex = cursor.getColumnIndex(MediaStore.Video.Media.DATA);
                            String videoPath = cursor.getString(columnIndex);
                            if(videoPath == null)
                                Log.e(TAG, "videoPath is null");
                            result.add(videoPath);
                        } else {
                            Log.e(TAG, "cannot use cursor");
                        }
                        cursor.close();
                    }
                }
            }
        }

        return result;
    }
}

Any help would be appreciated, thanks !

You can avoid intent.addCategory(Intent.CATEGORY_OPENABLE); if you want to open straight into the gallery. — DragonFire, Aug 05 '20 at 01:32

This is also working

// Start The Mutli Image Picker Intent
Intent intent = new Intent(Intent.ACTION_PICK,
                           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

intent.setType("video/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE,
                true);

final int RESULT_LOAD_IMAGE = 206;

activity.startActivityForResult(Intent.createChooser(intent,
                                                     "Select Picture"),
                                RESULT_LOAD_IMAGE);

mime types play a role here – DragonFire Jan 28 '20 at 13:12 — DragonFire, Jan 28 '20 at 13:12
