我已经在 gradle 中启用了 multidex，我的应用程序类是用 MultiDexApplication 扩展的......我也实现了支持 multidex 库......

一旦我的应用程序安装成功，应用程序就会开始崩溃。

注意：我的基础应用程序是从 Eclipse 安装的，现在 >我已经从工作室生成的 apk 升级了它。我的应用程序是一个启动器应用程序，它在启动阶段本身启动。

先取消勾选

Settings → Build, Execution, Deployment → Instant Run and uncheck Enable Instant Run

然后将此代码添加到你的 build.gradle 模块中：app inside defaultConfing:

defaultConfig {
    ....
    ....
    multiDexEnabled = true
}

将此代码添加到您的 build.gradle 模块中：应用程序内部依赖项：

dependencies {
    compile 'com.android.support:multidex:1.0.1'
    .....
    .....
}

在应用程序中打开 AndroidManifest.xml：

<application
    android:name="android.support.multidex.MultiDexApplication"
    .....
    .....
</application>

或者，如果您有自己的 Application 类，请从 MultiDexApplication 扩展它，例如：

 public class MyApp extends MultiDexApplication {
    .....
   }

希望对你有帮助
