Question

我正在开发Card Scanner应用程序，在我的应用程序中使用本机相机和条形码扫描apis（一切都很好用相机和条形码扫描），还使用带有Java POJO对象的Spring Android库进/出来休息apis。< / p>

问题 Android正在关闭我的应用程序而没有任何通知，QA报告了他正在测试并突然关闭应用程序的错误（行为类似于主页按钮按下）。

我对这个问题一无所知。我在最后重现了这个问题，并在logcat中得到了下面提到的日志。

这是我的日志：

注意： ContactSyncService是意向服务。我通过startService（）方法启动contactSyncService。

我没有覆盖IntentService的onStart和onStartCommand（）函数（正如Android Docs中提到的那样）

Answer 1

您错过了在ContactSyncService.onCreate（）中调用super.onCreate（）。

Android没有任何通知关闭我的应用程序
