[android] when app use mapbox sdk, how to config proguard-rules.pro file for app release

[tobrun]

@Larnoo thank you for this question, we package a proguard configuration file in the SDK. You activate it with using the following in your build.gradle:

release {
   minifyEnabled true
   proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}

Just for clarification - 5.0.2 works like a charm (proguard).
Actually I've tried last beta version 5.1.0-beta.1 and there was a problem on start (crash) - are you sure nothing has changed? If it's required I can check for logs.

Thank you for the report @mpuchala, going to use this issue to track it for 5.1.0 release.

pinpointed the native crash to ConnectivityReceiver.instance(appContext); in Mapbox.java.

Looking at the mapping.txt, currently nothing from our proguard configuration is picked up anymore.
This was a misconfiguration in gradle, consumer proguard was only activated for release builds.
