android - BroadcastReceiver 和 PHONE_STATE 不起作用

Question

我正在尝试使用具有 READ_PHONE_STATE 权限的 BroadcastReceiver。我要求用户获得运行权限(Android M)，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)

对于权限，我使用来自此链接的代码:https://stackoverflow.com/a/38764861

到目前为止，我希望我的手机状态 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 list 中它是:

<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" />

知道它应该如何相似或有什么问题吗？

为了能够检测到电话，您需要:

1 在 Manifest.xml 中，定义你的接收器并请求 PHONE_STATE 权限:

<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 添加一个扩展 BroadcastReceiver 的类 PhoneStateBroadcastReceiver 并覆盖 onReceive()

3 在运行时，request预先获得 PHONE_STATE 许可

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

通过系统对话框给它

4 打电话

您会看到在 onReceive() 中捕获的 Intent :

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