Hi Everyone,
What I want to do: I want to setup some routes overlay on google map in android !
What I have done so far: I have parsed the file (geo points) and have them ! I am using asynctask. My overlay class has a custom draw method. I have used destroyDrawingCache () in my draw function.
Problems I faced: While running the app, it gets size exceed error. I can see that the heap size is about 12mb at the time of the error.
Can anyone please help me out ? Thanks!
