java - 如何在 android 中正确启用 multiDex

Question

我已经设置了 MultiDex，但似乎无法处理我的情况，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。

此外，我正在使用新的 Android Studio 3.0 Canary 1，如果这可能有影响的话。

list

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

渐变

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 25
        multiDexEnabled true
        useLibrary 'org.apache.http.legacy'
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    ...
    compile 'com.android.support:multidex:1.0.1'

}

应用程序类

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

错误

试试这个

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

MultiDex.install(这个);此行从创建时删除
