WARN/ActivityManager(78): Launch timeout has expired, giving up wake lock! -> what is this

Question

As the title indicates i get this \"error\" when running my little app:

WARN/ActivityManager(78): Launch timeout has expired, giving up wake lock!
         


        

Answer 1

This error means your Activity is taking to long to start. If you are doing a lot of processing on the UI thread, Android kills your application. You should use AsyncTask for any processing intensive stuff.

If you could post your code and your SDK version, I can provide more help. There is also another thread on stackoverflow about this. Activity idle timeout for HistoryRecord?
