错误原因是：App中所引用的方法已经超过了最大数65536个方法！
解决方法：

步骤一：

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...

步骤二

dependencies { compile 'com.android.support:multidex:1.0.0' }

步骤三

第一种 情况：app没有重写Application

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

第二种情况：
App重写Application

public class MainApplication extends MultiDexApplication {

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

    @Override
    public void onCreate()
    {
        super.onCreate();

    }
}
