Android - Proguard con httpcore e httpmime con Android Studio e Gradle

Question

Sto sviluppando un'applicazione con Android Studio 1.0.2 e Gradle 1.0.0 utilizzando le librerie Apache httpmime e httpcore per entità multipart. Ecco il mio build.gradle:

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 21 
    buildToolsVersion "21.1.1" 

    // Something wrong with the http* libs 
    packagingOptions { 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/DEPENDENCIES.txt' 
     exclude 'META-INF/LICENSE.txt' 
     exclude 'META-INF/NOTICE.txt' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/notice.txt' 
     exclude 'META-INF/license.txt' 
     exclude 'META-INF/dependencies.txt' 
     exclude 'META-INF/LGPL2.1' 
    } 

    defaultConfig { 
     // ... 
    } 

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

} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile "com.android.support:support-v4:21.0.2" 
    compile 'org.apache.httpcomponents:httpcore:4.3.2' 
    compile 'org.apache.httpcomponents:httpmime:4.3.5' 
    compile 'net.hockeyapp.android:HockeySDK:3.5.0' 
} 

l'applicazione stessa e il 'normale' APK rilascio funzionano bene, ma quando sto cercando di utilizzare ProGuard ricevo il seguente messaggio di errore:

Secondo il i collegamenti forniti nel messaggio di errore sulle definizioni di classi duplicate e sulle classi di libreria in base alle classi di programma Devo usare qualcosa come -injars ... o -libraryjars ... nel mio proguard-rules.pro. Ma dal momento che utilizzo le librerie remote e non i file .jar, non so come usare queste opzioni proguard.

Così ho cercato su google per trovare una soluzione per il mio problema e hanno trovato diverse possibilità:

• ho scaricato i vasetti, li ha aggiunto alla mia cartella \app\libs e ha aggiunto le opzioni -libraryjar e/o -injar per entrambi i vasi, ma nessuna combinazione funzionerebbe: o i file non potevano essere trovati o letti, o ho avuto un errore che una delle librerie sarebbe stata elaborata due volte.

• Ho anche provato varie combinazioni di -keep class org.apache.**, -keep interface org.apache.**, -keep public class org.apache.** {*;}, -keepnames class org.apache.** {*;} con o senza l'{*;}, ma nessuno di loro lavoro.

• Ho provato anche l'opzione -dontwarn org.apache.** o -dontwarn org.apache.http.** che mi dà nessun errore durante la creazione della APK, ma quando cerco di stabilire una connessione Internet utilizzando il protocollo HTTP * librerie in App, l'applicazione si blocca con qualcosa di simile a un NoSuchMethodException.

Quindi la mia domanda è: esiste un modo per utilizzare le librerie remote e proguard? O è almeno possibile includendo il .jars nella mia cartella \ libs?

La ringrazio molto

Answer 1

Beh, io sto usando come questo

-dontwarn org.apache.commons.** 
-keep class org.apache.http.** { *; } 
-dontwarn org.apache.http.** 

Anche io sono la compilazione utilizzando vaso dentro le mie librerie cartella

compile files('libs/httpmime-4.3.5.jar') 
compile files('libs/httpclient-4.3.5.jar') 
compile files('libs/httpclient-cache-4.3.5.jar') 
compile files('libs/httpcore-4.3.2.jar') 

invece di utilizzare da Maven
