Question

* 通过执行此操作解决的问题： * 我通过更改我的onDestroy()活动和ServiceConnection::onServiceDisconnected()来解决了这个问题。

我添加了一个布尔值来检查我是否受限于名为boundToService的服务。 ServiceConnection：

private ServiceConnection mConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder service) {
        myService = ((EventService.MyBinder) service).getService();
    }

    public void onServiceDisconnected(ComponentName name) {
        // TODO Auto-generated method stub
        Log.i(getPackageName(), "ServiceConnection::onServiceDisconnected() called");
        boundToService = false;
    }
};

onDestroy()：

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    Log.e(getPackageName(), "Destroying Activity");
    if (boundToService && mConnection != null) {
        doUnbindService();
    }
}

这是在活动中完成绑定和解除绑定的方式：

public void doBindService() {
    bindService(new Intent(this, EventService.class), mConnection,
            Context.BIND_AUTO_CREATE);
    boundToService = true;
}

public void doUnbindService() {
    unbindService(mConnection);
    boundToService = false;
}

正如纪尧姆所说，首先打电话给super.onDestroy()是必须的。

我有Foreground Service轮询GPS数据，MapActivity每3秒请求一次数据。调用onDestroy()的{{1}}时，我收到此LogCat错误：

MapActivity

当然还有第175行的代码，其中异常是在我的程序中引起的：

如果您想要更多代码段，请告诉我。

*的修改 *

这是ServiceConnection的代码：

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    unbindService(mConnection);
    super.onDestroy();
}

public void doBindService() { //ComponentName service = startService(new Intent(this, // EventService.class)); bindService(new Intent(this, EventService.class), mConnection, Context.BIND_AUTO_CREATE); }是ServiceConnection的类型：

mConnection

Answer 1

这对我有用！只需从getApplicationContext（）调用函数unbindService（）而不是＆＃34;这个＆＃34;上下文。（同样用于绑定服务）

getApplicationContext().unbindService(mServiceConnection);

Answer 2

您可以在mService中将onServiceDisconnected设置为空，并在onDestroy中检查该值。像这样：

private ServiceConnection mConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName className, IBinder binder) {
            mService = ((LoadArticlesService.LoadArticlesBinder) binder).getService();
        }
        public void onServiceDisconnected(ComponentName className) {
            mService = null;
        }
    };

的onDestroy：

@Override
protected void onDestroy() {
    super.onDestroy();
    if (mService != null) {
        unbindService(mConnection);
    }
}

工作正常。

无法销毁活动（服务未注册）
