E/NMGDevice(1619): Exception:Attempt to invoke virtual method 'java.lang.String java.lang.String.trim()' on a null object reference

I can not find anymore information about this question. only i know when i load image will crash. my app is ok on other version, but on 5.0. i guess is ART and Dalvik, or something worng about "NMGDevice" class?

Why is the program crashing on Android 5?

Answer 1

From this, you ran out of memory:

 E/AndroidRuntime(1564): java.lang.OutOfMemoryError: Failed to allocate a 14908018 byte allocation with 10763166 free bytes and 10MB until OOM 

Then, you tried to access the null reference you got back:

E/NMGDevice(1619): Exception:Attempt to invoke virtual method 'java.lang.String java.lang.String.trim()' on a null object reference

Validate your return values. Stop swallowing exceptions.
