//在Android的清单文件做如下申明：

<application android:name="com.xyz.MyApplication">

</application>

//然后写这个类：

public class MyApplication extends Application{

    private static Context context;

    public void onCreate(){

        super.onCreate();

        MyApplication.context = getApplicationContext();

    }

    public static Context getAppContext() {

        return MyApplication.context;

    }

}

//调用MyApplication.getAppContext()来静态的获取你应用程序的context。
