Android Multidex RuntimeException

Question

I am trying to solve a problem with an Android application running, which has more than 65 thousand methods.
I have been following Google's docs about Multidex support, but I still cannot launch it successfully. It seems that the problem only appears on the SDK less than 21, because when I specify minSdkVersion 21 , it works well, however, as soon as I set it to minSdkVersion 15 , I get the following exception.

 FATAL EXCEPTION: main java.lang.RuntimeException: Unable to instantiate application custom.package.name.MyApplication: java.lang.ClassNotFoundException: Didn't find class "custom.package.name.MyApplication" on path: DexPathList[[zip file "/data/app/custom.package.name-2/base.apk"],nativeLibraryDirectories=[/data/app/custom.package.name-2/lib/arm, /vendor/lib, /system/lib]] at android.app.LoadedApk.makeApplication(LoadedApk.java:578) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4680) at android.app.ActivityThread.-wrap1(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1405) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) Caused by: java.lang.ClassNotFoundException: Didn't find class "custom.package.name.MyApplication" on path: DexPathList[[zip file "/data/app/custom.package.name-2/base.apk"],nativeLibraryDirectories=[/data/app/custom.package.name-2/lib/arm, /vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:511) at java.lang.ClassLoader.loadClass(ClassLoader.java:469) at android.app.Instrumentation.newApplication(Instrumentation.java:981) at android.app.LoadedApk.makeApplication(LoadedApk.java:573) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4680) at android.app.ActivityThread.-wrap1(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1405) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) Suppressed: java.io.IOException: Failed to open dex files from /data/app/custom.package.name-2/base.apk at dalvik.system.DexFile.openDexFileNative(Native Method) at dalvik.system.DexFile.openDexFile(DexFile.java:295) at dalvik.system.DexFile.<init>(DexFile.java:80) at dalvik.system.DexFile.<init>(DexFile.java:59) at dalvik.system.DexPathList.loadDexFile(DexPathList.java:279) at dalvik.system.DexPathList.makePathElements(DexPathList.java:248) at dalvik.system.DexPathList.<init>(DexPathList.java:120) at dalvik.system.BaseDexClassLoader.<init>(BaseDexClassLoader.java:48) at dalvik.system.PathClassLoader.<init>(PathClassLoader.java:65) at android.app.ApplicationLoaders.getClassLoader(ApplicationLoaders.java:58) at android.app.LoadedApk.getClassLoader(LoadedApk.java:376) at android.app.LoadedApk.makeApplication(LoadedApk.java:568) ... 9 more Suppressed: java.lang.ClassNotFoundException: custom.package.name.MyApplication at java.lang.Class.classForName(Native Method) at java.lang.BootClassLoader.findClass(ClassLoader.java:781) at java.lang.BootClassLoader.loadClass(ClassLoader.java:841) at java.lang.ClassLoader.loadClass(ClassLoader.java:504) ... 12 more Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack trace available

Here is what I have done so far:

• the created MyApplication class, which extends the application and points it to the AndroidManifest.xml file

• add dependency for build.gradle file

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

• multidex enabled in build.gradle

  multiDexEnabled true

• multidex is enabled in the MyApplication @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); } @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); }

Thanks in advance for your help!

Answer 1

After 3 days, it was eliminated by causing one of the dependencies.

EDIT . As @Asprelis pointed out, the lib causing the problems is net.java.truelicense

Answer 2

Try this, it works for me, pretty much copied from the current project ....

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' } 

Application class

 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" > ... 

It is worth noting that I had a similar problem until I added READ permission and expanded MultiDexApplication

Answer 3

The problem is that this obfuscator:

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