我有一个在API 14中工作的项目。现在我要转到API21,所以我要做需要做的更改

这是一款使用位置跟踪路线的应用程序。我有一个服务,负责定位的东西。但当我尝试绑定到该服务时,它总是返回错误,我不知道为什么

下面是我的代码。我甚至不知道该怎么开始看这个。服务不具有约束力的原因有哪些

下面是我的代码:

服务连接类

private ServiceConnection mConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder service) {
        // This is called when the connection with the service has been
        // established, giving us the object we can use to
        // interact with the service. We are communicating with the
        // service using a Messenger, so here we get a client-side
        // representation of that from the raw IBinder object.
        mServiceMessenger = new Messenger(service);

        // Now that we have the service messenger, lets send our messenger
        Message msg = Message.obtain(null, LOCATION_CHANGED, 0, 0);
        msg.replyTo = mClientMessenger;

        /*
         * In case we would want to send extra data, we could use Bundles:
         * Bundle b = new Bundle(); b.putString("key", "hello world");
         * msg.setData(b);
         */

        try {
            mServiceMessenger.send(msg);
        } catch (RemoteException e) {
            e.printStackTrace();
        }

        mBound = true;
    }

    public void onServiceDisconnected(ComponentName className) {
        // This is called when the connection with the service has been
        // unexpectedly disconnected -- that is, its process crashed.
        mServiceMessenger = null;
        mBound = false;
    }
};
bindService方法调用-val始终为false

public boolean bindService() {
    /*
     * Note that this is an implicit Intent that must be defined in the
     * Android Manifest.
     */
    Intent i = new Intent();
    i.setPackage("com.example.conor.routetracker.ACTION_BIND");

    boolean val =  getBaseContext().getApplicationContext().bindService(i, mConnection,
            Context.BIND_AUTO_CREATE);

    return val;
}

一行改变就可以节省时间

当我创造我的意图时,它应该是

Intent i = new Intent(getApplicationContext(), GPSService.class);
Intent i = new Intent(getApplicationContext(), GPSService.class);
public boolean bindService() {
    Intent i = new Intent("com.example.conor.routetracker.ACTION_BIND");
    i.setPackage("com.example.conor.routetracker")
    return getBaseContext().getApplicationContext().bindService(i, mConnection, Context.BIND_AUTO_CREATE);
}
