Android Studio - Le regole di 'mantenimento' di Proguard vengono ignorate?

Question

Recentemente ho migrato il mio progetto Android da Eclipse ad Android Studio.

La versione di debug dell'app creata da Android Studio funziona correttamente su un dispositivo, ma la versione di rilascio si arresta in modo anomalo all'avvio.

Ecco build.gradle fascicolo di mio app:

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

android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "com.example.myapp" 
     minSdkVersion 15 
     targetSdkVersion 23 
     versionCode 49 
     versionName "1.3.1" 
    } 
    buildTypes { 
     release { 
      minifyEnabled true 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
    packagingOptions { 
     //exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/LICENSE.txt' 
     exclude 'META-INF/NOTICE.txt' 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile 'com.android.support:design:23.1.1' 
    compile 'com.android.support:support-v13:23.1.1' 
    compile 'org.apache.httpcomponents:httpmime:4.2.3' 
    compile 'org.twitter4j:twitter4j-core:4.0.2' 
    compile 'com.facebook.android:facebook-android-sdk:4.8.2' 
    compile 'ch.acra:acra:4.7.0' 
    compile 'com.google.android.gms:play-services-analytics:8.3.0' 
    compile 'com.google.android.gms:play-services-ads:8.3.0' 
    compile 'com.google.android.gms:play-services-plus:8.3.0' 
    //compile 'com.google.android.gms:play-services:8.3.0' 
    compile 'com.google.android.gms:play-services-gcm:8.3.0' 
} 

Ecco il mio proguard-rules.pro di file:

01-06 11:48:58.503 1038-1476/? W/ActivityManager: Force finishing activity com.example.myapp/.SplashActivity 

così sembra le keep regole Ho specificato nel mio proguard-rules.pro f non vengono utilizzati come classe com.example.myapp.SplashActivity impossibile trovare.

Ho controllato la pagina Android Developers ProGuard e sembra che ho impostato tutto correttamente, quindi non ho idea del motivo per cui non funziona.

Qualcuno può consigliare cosa devo fare per finire con un apk offuscato che funziona?

Answer 1

ho trovato il problema. E 'stato nel file di build.gradle del mio progetto:

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 
    repositories { 
     jcenter()  // This is the default repo 
     mavenCentral() // This is the Maven Central repo 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:1.3.0' 
     classpath 'com.google.gms:google-services:1.5.0-beta2' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     jcenter()  // This is the default repo 
     mavenCentral() // This is the Maven Central repo 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

La soluzione era quella di cambiare il classpath 'com.android.tools.build:gradle:1.3.0' a classpath 'com.android.tools.build:gradle:1.5.0'.

(Ho scoperto questo con la creazione di un nuovo progetto di test e confrontando i valori nei rispettivi file build.gradle.)

Per inciso, il contenuto del mio file proguard-rules.pro ora è solo ...

# 
# Twitter - start 
# 

-dontwarn twitter4j.** 
-keep class twitter4j.** { *; } 

# 
# Twitter - end 
# 


# 
# Support library/ShareActionProvider - start 
# 

-keep class android.support.v7.internal.** { *; } 
-keep interface android.support.v7.internal.** { *; } 
-keep class android.support.v7.** { *; } 
-keep interface android.support.v7.** { *; } 

# 
# Support library/ShareActionProvider - start 
# 


# 
# ACRA - start 
# 

#ACRA specifics 
# Restore some Source file names and restore approximate line numbers in the stack traces, 
# otherwise the stack traces are pretty useless 
-keepattributes SourceFile,LineNumberTable 

# ACRA needs "annotations" so add this... 
# Note: This may already be defined in the default "proguard-android-optimize.txt" 
# file in the SDK. If it is, then you don't need to duplicate it. See your 
# "project.properties" file to get the path to the default "proguard-android-optimize.txt". 
-keepattributes *Annotation* 

# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'. 
# Note: if you are removing log messages elsewhere in this file then this isn't necessary 
-keep class org.acra.ACRA { 
    *; 
} 

# keep this around for some enums that ACRA needs 
-keep class org.acra.ReportingInteractionMode { 
    *; 
} 

-keepnames class org.acra.sender.HttpSender$** { 
    *; 
} 

-keepnames class org.acra.ReportField { 
    *; 
} 

# keep this otherwise it is removed by ProGuard 
-keep public class org.acra.ErrorReporter { 
    public void addCustomData(java.lang.String,java.lang.String); 
    public void putCustomData(java.lang.String,java.lang.String); 
    public void removeCustomData(java.lang.String); 
} 

# keep this otherwise it is removed by ProGuard 
-keep public class org.acra.ErrorReporter { 
    public void handleSilentException(java.lang.Throwable); 
} 

# 
# ACRA - end 
# 

... quindi non avevo bisogno di molte delle mie vecchie direttive o di quelle suggerite da Dhawal nella sua risposta.

NB - Capisco che le direttive ACRA non saranno richieste a partire da ACRA 4.8.

Answer 2

non utilizzare -keep public class com.example.myapp.SplashActivity

rimuovere tutte le righe per il file Proguard e utilizzare sotto modo, utilizzando questo Proguard non cambiare il nome della classe della vostra app (aggiungere di seguito le linee dipendere dal vostro requisito come la vostra applicazione non ha il fornitore di contenuti rimuove quindi quella linea).

-keep public class * extends android.app.Activity 
-keep public class * extends android.app.Application 
-keep public class * extends android.app.Service 
-keep public class * extends android.content.BroadcastReceiver 
-keep public class * extends android.content.ContentProvider 
-keep public class * extends android.app.backup.BackupAgentHelper 
-keep public class * extends android.preference.Preference 
-keep public class com.android.vending.licensing.ILicensingService 
-keep class org.xmlpull.v1.** { *; } 
-dontnote com.android.vending.licensing.ILicensingService
