Question

I’m trying to find out the maximal image resolution for processing photos in my app.
The first version of it is already online, and I got several OutOfMemoryError exception reports already.

Is there a way to determine the available memory, or is there some other strategy to find the best solution (in fact the maximum image resolution) for processing images on different phones?

Answer 1

You can get your approx. memory limit for your app (in megabytes) by using the activity managers getMemoryClass() method:

ActivityManager am = (ActivityManager)getSystemService(Service.ACTIVITY_SERVICE);
int maxMemoryInMb = am.getMemoryClass();

You can use that and calucate the maximum sizes of your image(s), this depends on the internal image format of course (see Bitmap.Config).
