Android Multidex RuntimeException

Question

Sto cercando di risolvere un problema con l'esecuzione di un'app per Android con oltre 65k metodi.
Ho seguito i documenti Google sul supporto Multidex, tuttavia non riesco ancora a eseguirlo correttamente. Sembra che il problema appaia solo su SDK inferiore a 21, perché quando specifico minSdkVersion 21, funziona bene, tuttavia una volta impostato su minSdkVersion 15, ottengo l'eccezione seguente.

Ecco quello che ho fatto finora:

• classe creata chiamato MyApplication che si estende Applicazione e specificato in AndroidManifest File .xml

• aggiunto dipendenza build.gradle file di

  compile 'com.android.support:multidex:1.0.1'

• multidex abilitato in build.gradle

  multiDexEnabled true

• multidex abilitato in classe MyApplication 012.360.339.206.

Grazie in anticipo per qualsiasi aiuto!

Answer 1

Dopo 3 giorni la sua risolto rimuovendo una delle dipendenze che provocato.

EDIT: Come @Asprelis sottolineato, il lib, che stava causando problemi è net.java.truelicense

Answer 2

Prova questo, questo sta lavorando per me, praticamente copiato da un progetto in corso ....

build.gradle

android { 
compileSdkVersion 23 
buildToolsVersion "22.0.1" 
defaultConfig { 
    applicationId "my.package.name" 
    minSdkVersion 16 
    targetSdkVersion 23 
    multiDexEnabled = true 
    versionCode 3 
    versionName "0.1.2" 
    renderscriptTargetApi 14 
    renderscriptSupportModeEnabled true 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile 'com.android.support:multidex:1.0.1' 
} 

classe Application

public class MyApp extends MultiDexApplication { 

    @Override 
    public void onCreate() { 
     super.onCreate(); 
    } 
} 

Manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 

... 

    <application 
    android:name=".MyApp" 
    android:allowBackup="true" 
    android:hardwareAccelerated="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 

... 

Vale la pena notare che ho avuto un problema simile fino ho aggiunto può READ e si estende MultiDexApplication

Answer 3

Il problema è che a causa di questo Obfuscator:

<dependency> 
     <groupId>net.java.truelicense</groupId> 
     <artifactId>truelicense-obfuscate</artifactId> 
     <version>${truelicense.obfuscate.version}</version> 
    </dependency>
