Question

我尝试在AsyncTask类的内部类中创建广播接收器

这里是我的代码

public class sendData extends Activity {
    private Intent myFiltered;

    public void send(String loc){
        myFiltered = new Intent(GPS_FILTER);
        myFiltered.putExtra("location_info_post", loc);
        this.sendBroadcast(myFiltered);
    }
}

我在AysncTask中的onPostExecuted中调用它

broadCast = new sendData();
        broadCast.send(MyGPS.location_info);

我得到错误作为力停止在我的程序中这主要是cuz null ponter异常，但我没有看到任何错误，任何想法？

这是我的日志猫
