我有一些应用程序使用警报,我做了一些代码来重启设备时从sqlite重置所有警报但重启时没有发生任何事情..什么是黄?
这是我的代码:
的manifest.xml
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name=".BootCompletedReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name=".ResetAlarmsService" >
</service>
接收器
