Android 对电话进行监听和挂断

1.添加权限

<!--拨打电话的权限-->
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<!--电话拦截-->
<receiver android:name=".receiver.PhoneBroadcastReceiver">
    <intent-filter android:priority="1000">
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>
<!-- 电话拦截服务 -->

<service android:name="com.lvshandian.menshen.service.PhoneService">
    <intent-filter>
        <action android:name="com.xinwang.telesms.PhoneReciever"></action>
        <action android:name="com.xinwang.telesms.server.IMICHAT" />
    </intent-filter>
</service>
