我正在尝试创建一个类似按钮的聊天头，当有人拨打我的手机时会显示该按钮 我遇到了两个问题：
1）呼叫接收器只会在用户启动我的应用程序时启动，我知道新的规则和接收器不会启动，直到应用程序运行仍然有办法让它在手机启动时启动吗？
2）它假设在通话时启动的服务不会启动（它在日志中显示方法被调用但服务不是）我想了解为什么以及如何解决它

答案 0 :(得分：0)
1）您可以设置一个特定的接收器，以便在手机开启时收到通知 android.intent.action.BOOT_COMPLETED ：
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name="com.my.CustomReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
2）如果手动启动，类似聊天头的叠加层是否有效？有异常吗？
