Java 如何在android中正确启用多索引

我已经设置了MultiDex，但似乎无法处理我的案例，我可能遗漏了什么？在某些应用程序上有相同的设置，在那里工作

另外，我正在使用新的安卓Studio 3.0金丝雀1，如果这可能有效果的话

清单

<application
        android:name=".Global"
        android:largeHeap="true"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

应用程序类

public class Global extends MultiDexApplication {
   @Override
    public void onCreate() {
        super.onCreate();
        MultiDex.install(this);
    }
}

错误

public class Global extends MultiDexApplication {
   @Override
    public void onCreate() {
        super.onCreate();
        MultiDex.install(this);
    }
}

试试这个

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

多索引安装（本）；创建一个类时删除此行

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

导入此库

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

像这样在你的渐变中设置multltidexenavbled为真

defaultConfig {
    multiDexEnabled true
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

        android:name="com.pkg.Multi_Dex"

我是你最简单的文件定义你的应用程序名称属性如下

defaultConfig {
    multiDexEnabled true
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

        android:name="com.pkg.Multi_Dex"

梯度文件

在你的活动中发生变化

public class YouApplication extends Application {

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

}

你能解释一下你的答案吗？把multiDexEnabled放在BuildTypes里就行了。没有帮助，还有什么你认为我可以检查的吗？dexOptions{javaMaxHeapSize“4g”}我认为你需要逐渐增加堆的大小你找到解决办法了吗？突然遇到同样的事情。
