我看到你使用 multiDexEnabled true。对于 API < 20，您必须使用 multidex 支持库。检查 doc.

我想你错过了 Application 的部分。
如果您没有自定义 Application class：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

否则，扩展 MultiDexApplication:

public class MyApplication extends MultiDexApplication { ... }

或...

public class MyApplication extends SomeOtherApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(context);
     Multidex.install(this);
  }
}

如果您已经这样做了：

Caution: Do not execute MultiDex.install() or any other code through reflection or JNI before MultiDex.install() is complete. Multidex tracing will not follow those calls, causing ClassNotFoundException or verify errors due to a bad class partition between DEX files.
