Android: libreria di caricamento delle app in fase di esecuzione su Lollipop ma non IceCreamSandwich

Question

Attualmente sto sviluppando un'app Android con Android Studio. Attualmente l'app si sta avviando perfettamente sui dispositivi Lollipop, ma si blocca al momento del lancio a causa di un dispositivo ClassNotFoundException su dispositivi pre-lollipop (che ho testato su ICS e fallisce).

La classe mancante è sempre da una libreria esterna in fase di esecuzione.

Ecco il file Gradle:

buildscript { 
    repositories { 
     maven { url 'https://maven.fabric.io/public' } 
    } 

    dependencies { 
     classpath 'io.fabric.tools:gradle:1.+' 
    } 
} 
apply plugin: 'com.android.application' 
apply plugin: 'io.fabric' 

android { 
    compileSdkVersion 23 
    buildToolsVersion '23.0.0' 
    defaultConfig { 
     applicationId 'com.kappsports.kapp10' 
     minSdkVersion 18 
     targetSdkVersion 23 
     versionCode 1 
     versionName '1.0.0' 
     multiDexEnabled true 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      shrinkResources true 
     } 
    } 
    lintOptions { 
     abortOnError false 
    } 
    dexOptions { 
     incremental true 
     javaMaxHeapSize '4g' 
    } 
} 

repositories { 
    mavenCentral() 
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" } 
    maven { url 'https://maven.fabric.io/public' } 
    jcenter() 
} 

dependencies { 
    compile fileTree(dir: 'libs', exclude: 'android-support-v4.jar', include: '*.jar') 
    compile('com.crashlytics.sdk.android:crashlytics:2.5.1@aar') { 
     transitive = true; 
    } 
    compile 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT' 
    compile 'com.github.johnpersano:supertoasts:1.3.4@aar' 
    compile 'com.google.code.gson:gson:2.3'

    compile 'com.makeramen:roundedimageview:1.3.0' 
    compile 'com.jakewharton:butterknife:6.0.0'

    compile 'com.google.android.gms:play-services:7.5.0' 
    //noinspection GradleCompatible 
    compile 'com.android.support:recyclerview-v7:22.2.1' 

} 

Ecco una Shunk di uscita logcat:

Sono attualmente in soluzione, per ora. Qualsiasi indizio su questo sarebbe apprezzato.

Grazie, Cordiali saluti.

Answer 1

1) aggiungere il supporto multidex per la vostra applicazione:

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

2) Impostare l'applicazione come MultiDexApplication. Selezionare una delle seguenti opzioni:

Questo è il codice sorgente della classe di Android MultiDexApplication:

public class MultiDexApplication extends Application { 
    public MultiDexApplication() { 
    } 

    protected void attachBaseContext(Context base) { 
     super.attachBaseContext(base); 
     MultiDex.install(this); 
    } 
} 

Opzione 1) È possibile estendere l'applicazione personalizzata da MultiDexApplication:

public class MyApplication extends MultiDexApplication { 
    // Your application implementation here 
} 

Opzione 2) È possibile estendere l'applicazione personalizzata dalla classe predefinita Application, quindi è necessario chiamare MultiDex.install a attachBaseContext(Context base) metodo:

public class MyApplication extends Application { 

    protected void attachBaseContext(Context base) { 
     super.attachBaseContext(base); 
     MultiDex.install(this); 
    } 

    // Your application implementation here 
} 

Opzione 3) Se non si dispone di qualsiasi applicazione personalizzata e non si vuole alcuna, è sufficiente impostare il tuo nome dell'applicazione (a AndroidManifest.xml) per MultiDexApplication:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.android.multidex.myapplication"> 
    <application 
     ... 
     android:name="android.support.multidex.MultiDexApplication"> 
     ... 
    </application> 
</manifest> 

Nota: Se si utilizza una classe di applicazioni personalizzate (vedi Option1 e Option2), application tag di android:name deve essere già impostato per la classe di applicazioni personalizzate.

3) Aggiungi multiDexEnabled true al file di build.gradle:

defaultConfig { 
    // Other settings here 
    multiDexEnabled true 
} 

More information.

Answer 2

Ho dimenticato di aggiungere questa riga a destra dopo la chiamata super nella onCreate() il metodo della mia classe di applicazioni personalizzate:

MultiDex.install(getBaseContext()); 

Grazie Kane per la soluzione!

Answer 3

Su alcuni dispositivi di fascia bassa che aggiungono MultiDex.install(getBaseContext()); a MyApplication onCreate() non ha funzionato? causando java.lang.NoClassDefFoundError:

Che cosa ha fatto il lavoro stava aggiungendo MultiDex.install(getBaseContext()); a MyApplication attachBaseContext(Context base)

public class MyApplication extends Application { 
... 
    @Override 
    protected void attachBaseContext(Context base) { 
     super.attachBaseContext(base); 
     MultiDex.install(base); 
    } 
... 

Answer 4

È possibile aggiungere questo tag applicazione di file manifesto.

android:name="android.support.multidex.MultiDexApplication"
