[configuration] Configure Proguard Rules to compile working release apk

[nijuyonkadesu]

Description

• With minifyEnabled true, the application crashes
• Need to configure proguard.txt to exclude obfuscation of certain classes
• Neet to identify the exact reason of crash

Error insights

• (k7.u.b(Unknown Source:2490) in the stack trace) and make sure that you are casting the correct type and that the casting operation is valid
• Trying to cast a parameterized type that has been erased at runtime due to Java's type erasure. In such cases, casting to ParameterizedType may not be possible

Gets more annoying !

tried excluding com.google.android.material, entire retrofit and coil too, the minify build doesn't work.

Having this,

• -keepclasseswithmembernames class one.njk.sao.models.** { *; }
• -keepclasseswithmembernames class one.njk.sao.data.ApiResult { *; }

or @Keep annotation at dataclass, it fails either way.

Error happens at

It happens on WaifuApiRepositoryImpl. Just remove try {..} catch {...} block when testing
