Out of Memory : android.support.v7.app.AppCompatActivity.onCreate

Question

we recently switched to using AppCompatActivity instead of FragmentActivity and now some devices are randomly crashing with the following error. No idea why this is happening.

Fatal Exception: java.lang.OutOfMemoryError: Failed to allocate a 16008012 byte allocation with 4277152 free bytes and 4MB until OOM

Answer 1

You are trying to load an image using the BitmapFactory right?

I assume that your image is too big:

16008012 byte allocation with 4277152 free bytes and 4MB until OOM

Your image is 16008012 but you only have 4277152 bytes free. Try using a smaller image.

Answer 2

This happened to me when I set a rather large drawable as the windowBackground property of the activity's theme. Reducing the size of the image should fix it
