problemi proguard in studio Android

Question

Ho sviluppato un'applicazione in Android Studio. Funziona bene nella versione di debug ma quando provo a creare una versione di rilascio con proguard, vengono visualizzati centinaia di avvisi e non riesco a sbarazzarmene usando l'opzione -keep.

mio build.gradle è

apply plugin: 'com.android.application' 
apply plugin: 'maven' 
apply plugin: 'com.google.gms.google-services' 


android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "com.ruben.xradar" 
     minSdkVersion 19 
     targetSdkVersion 23 
     versionCode 22 
     versionName "0.22" 
     multiDexEnabled true 
    } 

    dexOptions { 
     javaMaxHeapSize "4g" 
    } 
    packagingOptions { 
     exclude 'META-INF/NOTICE.txt' 
     exclude 'META-INF/LICENSE.txt' 
    } 

    buildTypes { 
     release { 
      //Esto es para oscurecer y minificar el código 
      minifyEnabled true 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
     debug { 
      debuggable false 
     } 
    } 
} 

dependencies { 
    compile(project(path: ':backend', configuration: 'android-endpoints')) { 
     exclude group: 'com.google.guava' 
    } 
    compile fileTree(dir: 'libs', include: ['*.jar'])

etc, etc... 

Non so perché, ad esempio, l'aggiunta di -keep classe jp.wasabeef * * {*;} non scompaiono gli avvisi relativi a jp.wasabeef.

Qualcuno può aiutarmi?

è necessario gestire ciascuna libreria importata (in app.gradle) utilizzando le regole proguard.

Answer 2

È necessario escludere questo codice libreria aggiunto esternamente dall'offuscamento. Quindi è necessario trovare compatibile -dontwarn.

se si utilizza qualsiasi POJO allora è anche necessario escludere usarli:

-keepclassmembers class yourpackage. {< campi>; } **
