Android:app在Lollipop上运行时加载库,但不是IceCreamSandwich

Edo*_*hes 16 android classnotfoundexception android-4.3-jelly-bean android-gradle-plugin android-5.0-lollipop

我目前正在使用Android Studio开发Android应用.目前,该应用程序在Lollipop设备上完美启动,但由于ClassNotFoundException在棒棒糖前设备(我已在ICS上测试并且失败),在发布时崩溃.

缺少的类总是在运行时来自外部库.

这是gradle文件:

我现在暂时没有解决方案了.任何关于这一点的线索将不胜感激.

感谢和问候.

1)为您的应用添加multidex支持:

compile 'com.android.support:multidex:1.0.1'
Run Code Online (Sandbox Code Playgroud)

2)将您的应用程序设置为MultiDexApplication.选择以下选项之一:

这是android MultiDexApplication类的源代码:

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

    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}
Run Code Online (Sandbox Code Playgroud)

选项1)您可以从MultiDexApplication以下位置扩展自定义应用程序:

public class MyApplication extends MultiDexApplication {
    // Your application implementation here
}
Run Code Online (Sandbox Code Playgroud)

选项2)你可以扩展默认情况下,从您的自定义应用程序Application类,那么你需要调用MultiDex.install的attachBaseContext(Context base)方法:

public class MyApplication extends Application {

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

    // Your application implementation here
}
Run Code Online (Sandbox Code Playgroud)

选项3)如果您没有任何自定义应用程序且不需要任何自定义应用程序,只需将应用程序名称(在AndroidManifest.xml中)设置为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>
Run Code Online (Sandbox Code Playgroud)

注意:如果您使用的是自定义应用程序类(请参阅Option1和Option2),则必须已将application标记android:name设置为自定义应用程序类.

3)将multiDexEnabled true设置添加到build.gradle文件:

defaultConfig {
    // Other settings here
    multiDexEnabled true
}

我忘了在我的自定义应用程序类的onCreate()方法中的超级调用之后添加此行: 

 MultiDex.install(getBaseContext());
