它的失败@下线 -
bindService(intent, m_serviceConnection, Context.BIND_AUTO_CREATE);
以下是追踪....

public class MainActivity extends Activity

private ServiceConnection m_serviceConnection = new ServiceConnection()

您需要在代码中添加它。
@Override
protected void onDestroy() {
super.onDestroy();
unbindService(m_serviceConnection);
Toast.makeText(MainActivity.this, "Service Un-Binded", Toast.LENGTH_LONG).show();
};
另一个好的做法是添加一个标志来了解添加服务的时间。
private boolean m_serviceBound = false;
private ServiceConnection m_serviceConnection = new ServiceConnection()
{
...
};
@Override
protected void onCreate(Bundle savedInstanceState)
{
...
Intent intent = new Intent(this, CallNotifierService.class);
bindService(intent, m_serviceConnection, Context.BIND_AUTO_CREATE);
m_serviceBound = true;
...
}
@Override
protected void onDestroy() {
...
if (m_serviceBound) {
unbindService(m_serviceConnection);
m_serviceBound = false;
}
...
};
如果您在应用程序生命周期的不同部分中绑定和取消绑定服务,这将非常有用。
是您可以在活动中取消绑定服务的另一个地方。
当您只想在Activity位于前台时才想与服务交互时,这种方法更为可取。 See official Android Developer guide suggestion
Override
protected void onStop() {
super.onStop();
unbindService(m_serviceConnection);
};
在这种情况下,绑定服务的首选方法是在Activity的onStart()
方法中。
