Add code for Android 8.1:

    public static Intent getPickImageIntent(Context context) {
        StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
        StrictMode.setVmPolicy(builder.build());
        Intent chooserIntent = null;

WHY are you removing an item from the intent list after having added it??? Doesnt that defeat the purpose???
