Answer 1

I think, if you are using intent from fragment and if your using getActivity() make sure you have attached your fragment to your activity otherwise it may throw you null pointer. therefore in my case i used a workaround to get the context, which you can use it

create a gobal variable View rootView and initialize it OnViewCreated() method and you can use accordingly.

public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_OK) {
    return;
}

if (requestCode == REQUEST_IMAGE_CAPTURE) {
Log.d(UploadPicturesFragment.class.getSimpleName(),
            "IMAGE URI NOT NULL: " + (mHighQualityImageUri == null));
    try {
        Bitmap bitmap = MediaStore.Images.Media.getBitmap( rootView.getContext().getContentResolver(),
                mHighQualityImageUri);
        DroomUtil.beginCrop(mHighQualityImageUri, rootView.getContext(), this, true, bitmap.getWidth(),
                bitmap.getHeight());
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}}

Answer 2

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.net.Uri.getScheme()' on a null object reference

That means mHighQualityImageUri is null, in all likelihood. This will occur if you failed to hold onto that Uri using onSaveInstanceState(). It is entirely possible that your process will be terminated while your app is in the background and the camera app is in the foreground.
