我现在无法确定错误在哪里，我在互联网上搜索但没有答案，所以如果有人有任何想法告诉我，这是我的应用程序gradle，对我来说这很重要:)谢谢大家

我看到您使用了multiDexEnabled true。对于API < 20，您必须使用multidex支持库。检查doc。

我认为您缺少Application的一部分。
如果您没有自定义的Application类:

<?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 { ... }

要么...

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:

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.
