ChooserActivity has leaked IntentReceiver com.andr

Question

I'm trying to open a xml file with default application on the phone when clicking a button of my app. after google i found and followed this: http://www.androidsnippets.com/open-file-with-default-application-using-intents , my code is just as:

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(_file), "application/*"); 
startActivity(intent);

it works on my phone, but the logcat got some errors:

I didn't register anything, and don't know how to fix that "Are you missing a call to unregisterReceiver()", how can i change my code?

Answer 1

I'm not 100% sure but if it works fine AND throws the exception probably you need do nothing about it. It can be problem of your device, for example, error in customised by vendor Android OS. Try to test it on emulator, if it wouldn't throw an exception, just leave it as is. I think your code is fine.
