我想创建曲棍球成绩的应用程序。在主页上，用户选择他最喜欢的球队，然后他会在片段“未来比赛”中看到他最喜欢的球队的比赛。
此后，他可以选择自己喜欢的匹配项（通过单击匹配项），然后，如果该匹配项中的分数发生了变化，则用户会收到有关分数变化的通知。
但是我有问题，因为当我看到将来的比赛时，在点击比赛后，应用程序会掉落。
我对解决这个问题一无所知。
我需要这方面的帮助。

最佳答案
您需要明确地定义要启动的服务。
getActivity().startService(new Intent(getActivity(), GameChangeService.class).putExtra(Tools.INTENT_EXTRA_ID,id));
您还需要在AndroidManifest.xml中定义您的服务。
<service android:enabled="true" android:name=".GameChangeService" />
