App flicks or twinkles at some point on android 4.2.2

I have spent long time on this, this is driving me craze.

My app works all fine on android 4.1 and below. But it have a big problem running on android 4.2.2

At some point the app just start a endless flicking or twinkling, until it eat up all memory of the phone, then the phone died.

I have no idea where this problem is triggered, i don't know which line of code cause this strange problem. Because it has not bad log at all, it runs from onCreate to the final line of onResume and its all fine, but after that it just jumped in to onDestroy automatically, then run into onCreate again, it's an endless loop.

During the loops, all logs i have got is like this:

Any words or recommendations to help me find out where the problem is are appreciated. Thanks in advance.

Solution

  • Finally i solved this problem by myself.

    In my case, it caused by the abuse of 

    updateConfiguration()

    i use it to manage language in each activity inside

    onConfigurationChanged()

    Once the change of the orientation triggered the onConfigurationChanged(), inside it will call updateConfiguration() which will trigger onConfigurationChanged() again, that will running into an endless loop.

    So carefully review your use of these two functions, you will find something.
