MultiDex NoClassDefFounderror

我已将我的应用程序转换为MultiDex以承受64k dex限制。现在它看起来像这样:

public class App extends MultiDexApplication {

private AppWrapper instance;

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

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

    if (instance == null) {
        instance = new AppWrapper(this);
    }
}
}

我已将所有常用逻辑从App移至AppWidget以使MultiDex正常工作。它在其他队友的电脑上运行正常。但不是和我在一起。它不断在应用程序创建java.lang.NoClassDefFoundError上投掷:

您的 AppWrapper 类无法加载,因为 retrofit.ErrorHandler 接口未包含在主dex文件中。

如何计算要放在main-dex-list文件中的类?
script可以为您生成它。我写了一篇blogpost来说明如何使用它。

如果一切正常,但会出现此错误,

尝试停用即时运行!!!

当我禁用它时,所有类都已正确加载。

如果您正在扩展MultiDexApplication,则不需要进行MultiDex.install(context)调用,因为它已经发生(请参阅源链接)。如果你需要使用attachBaseContext,那么只需确保调用super.attachBaseContext(context)。

如果有人因为他们的应用程序类没有在Lollipop之前的设备上找到,但是应用程序在Lollipop及以上版本上运行正常,那么这似乎是Jack和Multidex的一个已知问题。

参考:Jack Issue 224026

答案 4 :(得分:3)

NoClassDefFound可能发生在任何没有加载到早于Lollipop且启用了multidex的API的设备上的任意类。如果您正确设置了ProGuard,那么您可以轻松使用,而不会产生MultiDex开销,从而使您的应用程序在发布版本中启动缓慢,尤其是在旧设备上。但是,在调试模式下开发应用程序时,您不希望ProGuard减慢速度。如果您尝试在禁用ProGuard的情况下启动调试版本,则会开始出现com.android.dex.DexIndexOverflowException: Cannot merge new index 72118 into a non-jumbo instruction!等构建错误

所以真正想要的是启用ProGuard并且仅在发布版本上禁用multidex,而调试版本应与禁用Proguard和启用multidex相反。当然,您还必须挑剔并使用较少的依赖项,因为您的发布版本受到64K限制。

这需要将build.gradle设置为具有buildTypes配置,并且仅为调试编译multidex支持库依赖项。

还必须将Application子类设置为从不同的子类派生,具体取决于您是否处于multidex模式。这可以使用gradle manifest merger原则,通过为调试版本定义覆盖清单,然后以不同方式指定Application类来实现。

这是相关的app模块build.gradle:

android {
...
    buildTypes {
        debug {
            minifyEnabled false //Disabled Proguard
            multiDexEnabled true // Enabling multi-dex support.
        }
        release {
            minifyEnabled true //Enabled Proguard
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            multiDexEnabled false // Disable multi-dex support.
        }
    }
    dependencies {
        debugCompile 'com.android.support:multidex:1.0.1' //debugCompile makes it included only for debug builds
        ...
    }
}

如果您不使用Application子类,那么您需要做的就是指定应用程序子类android.support.multidex.MultiDexApplication的名称,如https://developer.android.com/studio/build/multidex.html中所述,但您想要这样做用于您的调试版本。

为此,您必须在调试和发布变体文件夹层次结构中指定覆盖文件,如下所示:

src
    - main
        - AndroidManifest.xml
        - java/com/yourcompany/MyApplication.java (extends from BaseApplication)
    - release
        - java/com/yourcompany/BaseApplication.java (extends from Application)
    - debug
        - AndroidManifest.xml
        - java/com/yourcompany/BaseApplication.java (extends from MultiDexApplication)

是的,您在主模块的文件夹旁边创建了debugrelease个文件夹。在以下文件中添加以下文件:

的调试/ AndroidManifest.xml中

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    >
    <application
        android:name="com.yourcompany.MyApplication"
        tools:replace="android:name"/>
</manifest>

此清单仅包含在调试版本中,并且将在您的版本1中被忽略。

释放/ JAVA / COM / yourcompany / BaseApplication.java

public class BaseApplication extends Application {
}

调试/ JAVA / COM / yourcompany / BaseApplication.java

public class BaseApplication extends MultiDexApplication {
}            

主/ JAVA / COM / yourcompany / MyApplication.java

public class MyApplication extends BaseApplication {
    @Override
    public void onCreate() {
        super.onCreate();
        //Init database, etc. etc.;
    }
}            

通过这种方式,您可以将App的功能添加到MyApplication.java,同时具有不同的基类。

我也遇到过这种问题。我的解决方案是: 在我的build.gradle文件中,依赖项中有多个compile 'com.android.support:multidex:1.0.0'条目。像:

dependencies {    
compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:multidex:1.0.0'
// other dependencies ........
}

只放一个编译'com.android.support:multidex:1.0.0'之类的:

dependencies {    
compile 'com.android.support:multidex:1.0.0'
// other dependencies ........
}

答案 6 :(得分:0)

我终于解决了!原因不在onCreate()方法中。来自logcat的这条线引起了我的注意:

I/dalvikvm﹕ Failed resolving     Lcom/playday/app/core/AppWrapper; interface 8940 'Lretrofit/ErrorHandler;'
W/dalvikvm﹕ Link of class     'Lcom/playday/app/core/AppWrapper;' failed

此行在所有MultiDex日志之前触发。问题的根源是Retrofit ErrorHandler接口,AppWrapper实现了该接口。

正如@AlexLipov在回答中所说,Dalvik无法找到ErrorHandler课程而无法加载AppWrapper

无论如何,解决方案不是直接由ErrorHandler实现AppWrapper,而是将其拉入私有变量。

答案 7 :(得分:0)

我尝试了很多解决方案,但没人为我工作。终于,我找到了:

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

这是解决我的问题的唯一方法。也许有人遇到相同的问题,这可能会有所帮助:)

答案 8 :(得分:0)

在gradle中添加以下依赖

implementation 'com.android.support:multidex:1.0.3'

在应用级 build.gradle 中,添加如下参数。

 defaultConfig {
     multiDexEnabled = true
 }

在应用程序类中,添加以下行

MultiDex.install(this);
