Android 四大组件之 BroadcastReceiver_3 实现开机启动拦截电话服务

拦截电话服务(ListenCallService)参考：https://blog.csdn.net/whjk20/article/details/112988381

这里实现开机启动完成后，启动拦截电话的服务。

1.创建接收器，处理action: Intent.ACTION_BOOT_COMPLETED

2. AndroidManifest中静态注册接收器，当应用安装时注册，收到广播时创建对象。

3.声明权限(使用Intent.ACTION_BOOT_COMPLETED需要的权限) ：

4. 输出结果

5. 注意事项：

1.创建接收器，处理action: Intent.ACTION_BOOT_COMPLETED

即启动ListenCallService (使用onStartService , 什么时候停止??)

//静态注册，当应用安装时注册，收到广播时创建对象。
public class BootCompleteReceiver1 extends BroadcastReceiver {private static final String TAG = "BootCompleteReceiver1";private void log(String msg) {Log.d(TAG, msg);}@Overridepublic void onReceive(Context context, Intent intent) {String intentAction = intent.getAction();log("onReceive intentAction=" + intentAction);Intent callIntent = new Intent(context, ListenCallService.class);context.startService(callIntent);log("start ListenCallService done");}
}

2. AndroidManifest中静态注册接收器，当应用安装时注册，收到广播时创建对象。

        <receiver android:name=".BootCompleteReceiver1"><intent-filter><category android:name="android.intent.category.DEFAULT"/><action android:name="android.intent.action.BOOT_COMPLETED"/></intent-filter></receiver>

3.声明权限(使用Intent.ACTION_BOOT_COMPLETED需要的权限) ：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

4. 输出结果

01-27 11:04:36.961 D BootCompleteReceiver1: onReceive intentAction=android.intent.action.BOOT_COMPLETED
01-27 11:04:36.970 D BootCompleteReceiver1: start ListenCallService done

01-27 11:04:36.986 D ListenCallService: onCreate
01-27 11:04:37.006 D ListenCallService: onCreate - already granted permission.READ_CALL_LOG
01-27 11:04:37.008 D ListenCallService: onStartCommand
01-27 11:04:37.008 D ListenCallService: onCallStateChanged state=0, phoneNumber=

01-27 11:04:55.328 D ListenCallService: onCallStateChanged state=1, phoneNumber=10086
01-27 11:04:55.450 D ListenCallService: onCallStateChanged endCall ret=true

01-27 11:04:55.843 D ListenCallService: onCallStateChanged state=0, phoneNumber=10086

5. 注意事项：

(1) 需要保证开机后，应用已经跑起来了，否则有可能不会收到广播 (这里开机后手动启动了应用)

再去实现能自动接收到开机完成的广播
