     compile 'com.android.support:multidex:1.0.3'
}

manifest

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:name="com.example.ApplicationManager">

    <activity android:name=".MainActivity"
        android:windowSoftInputMode="adjustResize"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

And com.example.ApplicationManager

public class ApplicationManager extends Application {

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

回答1:

try this code.

public class ApplicationManager extends MultiDexApplication{

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

回答2:

You have used application class in extend: Use below class in extends application class:

public class ApplicationManager extends MultiDexApplication {

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

and also put this line in application class in manifest:

android:allowBackup="false"
android:hardwareAccelerated="true"
android:icon="@drawable/app_icon_new"
android:label="@string/app_name"
android:largeHeap="true"
android:theme="@style/AppTheme"
