Cannot fit requested classes in a single dex file (# methods: 90221 > 65536)

Question

Each time I compile my android studio app to an APK I get this error message. My android studio version:

Error Messages:

How do you fix this error? It would be greatly appreciated if someone told me how to fix it.

Answer 1

It appears that you must enable multiDexEnabled just beneath your minSdkVersion in the build.gradle(:app).

multiDexEnabled = true;

The background reason for this I have not yet fully investigated since in some instances, it will only fail during the building of the app-bundle and not on emulator.

Answer 2

You need to make

minSdkVersion 21

At least 21.
