BroadcastReceiver 和 PHONE_STATE 不起作用

Question

我正在尝试在获得 READ_PHONE_STATE 许可的情况下使用 BroadcastReceiver。我向用户请求运行 (Android M) 的权限，但毕竟我得到了权限拒绝：

W/BroadcastQueue: Permission Denial: receiving Intent { act=android.intent.action.PHONE_STATE flg=0x10 (has extras) } to com.pb.qostest/.network.PhoneStateBroadcastReceiver requires android.permission.READ_PRIVILEGED_PHONE_STATE due to sender android (uid 1000)

为了获得许可，我正在使用来自此 link 的代码：

到目前为止，我希望我的 phone 状态 BroadcastReceiver 只打印一些东西，所以它看起来像这样：

public class PhoneStateBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {   
         Log.d("RECEIEVER", "PhoneStateBroadcastReceiver Receiver started!");
    }
}

无论如何，由于上面的权限被拒绝，所以没有打印任何内容。

在清单中是：

<receiver
    android:name=".network.PhoneStateBroadcastReceiver"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>
...
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

知道它应该有什么相似之处或者有什么问题吗？

Answer 1

为了能够检测到 phone 来电，您需要：

1 in Manifest.xml，定义你的接收者并请求PHONE_STATE许可：

<receiver android:name=".network.PhoneStateBroadcastReceiver">
<intent-filter>
  <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>
// ...
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

2 添加一个 class PhoneStateBroadcastReceiver 扩展 BroadcastReceiver 并覆盖 onReceive()

3 在运行时，request PHONE_STATE 预先许可

    ActivityCompat.requestPermissions(myMainActivity,
            new String[]{Manifest.permission.READ_PHONE_STATE},
            READ_PHONE_STATE_CODE);

并通过系统对话框给它

4 拨打 phone 电话

您将看到在 onReceive() 中捕获的意图：

intent: Intent { act=android.intent.action.READ_PHONE_STATE flg=0x10 cmp=com.myApp.network.PhoneStateBroadcastReceiver (has extras) }
Action: android.intent.action.PHONE_STATE
