Been trying to figure out this issue. I'm a bit of an Android noob, I can handle code but when it comes to configuration issues I'm a bit lost. I've inherited this project and haven't found a solution yet.
I'm getting a vague proguard issue when building the APK. If I remove proguard and minifyEnabled from the Gradle config for the release build variant, the APK builds fine, although it's larger than it should be by 10 mb.
release {
debuggable false
//minifyEnabled true
//proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
signingConfig signingConfigs.release
zipAlignEnabled true
multiDexEnabled true
}
Some more background, this project hasn't been updated for about two years, and now I've updated some tools to the latest (Gradle, Android Studio, Android 7).
One of the warnings I'm getting is about deprecations. Would that be able to cause this proguard issue? I've looked at some of the deprecation issues and they're not something I can fix fast, so I am skipping that for now, unless someone is sure this will lead me to some sort of solution.
If you need more information let me know, but there's a lot here already, I think. I'm not posting the proguard file because I've tried using the minifyEnabled setting and commenting out proguardFiles getDefaultProguardFile... and the error still occurred. I might be wrong, but I assume this runs proguard without the config file. Anyway, let me know if you need that too.
Error messages below.
Notes:
1 - No idea where the okio.Okio issue is coming from, since I can't find a trace of that library and I did clean the build folder several times. It must be part of one of the project dependencies !?
2 - *** means I've removed some text to keep the name of the company I work for annonymous.
