I think I see what the problem is.
It doesn't like you doing those file operations on the UI thread because of
something called *strict mode*. You can tell it to turn that off by
modifying the onCreate method in ImageGridActivity like so:
@Override
protected void onCreate(Bundle savedInstanceState) {
* // if (BuildConfig.DEBUG) {*
* // Utils.enableStrictMode();*
* // }*
* StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()*
* .permitAll().build();*
*
*
* StrictMode.setThreadPolicy(policy);*
super.onCreate(savedInstanceState);
if (getSupportFragmentManager().findFragmentByTag(TAG) == null) {
final FragmentTransaction ft = getSupportFragmentManager()
.beginTransaction();
ft.add(android.R.id.content, new ImageGridFragment(), TAG);
ft.commit();
}
}
Thanks.
