Android activity runs twice

I was running my app on a Nexus 7 2013 and in the logcat I noticed some logs are running twice. After writing several magazines, I came to the conclusion that each action is performed twice on the tablet. It is strange to think that on a phone (LG G3 or Samsung galaxy s4 mini) magazines are printed only once.

After some research, I tried to add android:launchMode="singleTop"

either singleTask

or singleInstance

, but none worked. Also I have some intentions in flag actions: intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

and 2 AsyncTasks

.

Is there a way that causes problems or asynthesis?
