Android unregister receiver error when choosing image using intent

To solve error like following

Activity com.android.internal.app.ChooserActivity has leaked IntentReceiver com.android.internal.app.ResolverActivity$1@417ffc78 that was originally registered here. Are you missing a call to unregisterReceiver()?

To solve above error make sure your activity is not "singletask". please check your manifist. if activity is "singletask" then remove it and try.
