Select image from gallery in Android Fragment

Question

I want to choose the gallery’s intent in the fragment. When the user selects an option to select an image from the gallery, then the gallery opens, and onActivityResult fragment immediately appears. And when the user selects the image, then onActivityResult () is not called. So I'm not able to select images from the gallery. Belo - my code to open the gallery -

Intent intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    intent.setType("video/, images/");
    startActivityForResult(intent, 2);

and here is my onActivityResult -

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult"); // not printed
    Toast.makeText(mContext, "aaaa"+requestCode, Toast.LENGTH_SHORT).show();
}

What a problem in my code.

Thanks in advance.

Use this to open the image selection for Android:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), GALLERY_INTENT_CALLED);
} else {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/*");
    startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
}

and for onActivityResultuse this:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    Cursor cursor = null;
    if (resultCode != Activity.RESULT_OK)
        return;
    if (data == null)
        return;
    Uri originalUri = null;
    if (requestCode == GALLERY_INTENT_CALLED && data != null) {
        originalUri = data.getData();
        String[] filePathColumn = {MediaStore.Images.Media.DATA};

        cursor = getActivity().getContentResolver().query(originalUri,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        filePath = cursor.getString(columnIndex);
        cursor.close();
        Log.d("path of uri", filePath);

    } else if (requestCode == GALLERY_KITKAT_INTENT_CALLED && data != null) {
        originalUri = data.getData();

        final int takeFlags = data.getFlags()
                & (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        // Check for the freshest data.
        getActivity().getContentResolver().takePersistableUriPermission(
                originalUri, takeFlags);
        Log.d("Uri: ", originalUri.toString());

        filePath = getPath(getActivity(), originalUri);

        Log.d("filepath", filePath);

    }
