解决方法：

1 ActiveAndroid 集成

repositories {

        google()
        jcenter()

        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }

}

compile 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'

2 在 MyApplication 中调用 ActiveAndroid.initialize(this);

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ActiveAndroid.initialize(this);
    }

    @Override
    public void onTerminate() {
        super.onTerminate();
        ActiveAndroid.dispose();
    }
}

3 在 AndroidManifest.xml 文件仲 Application 标签下添加.

        <provider
            android:name="com.activeandroid.content.ContentProvider"
            android:authorities="com.x'x'x.x'x'x'x'x" 你的包名
            android:enabled="true"
            android:exported="false" />

问题解决。
