Browse Source 
This change adds annotation in the generated code. If the flag is read
only, annotations @com.android.aconfig.annotations.AssumeTrueForR8 or
@com.android.aconfig.annotations.AssumeFalseForR8 will be added in to
the corresponding methods in the interface FeatureFlags, and class
Flags.

Test: atest aconfig aconfig.test.java
