java - 无法使用 BroadcastReceiver [Marshmallow] 检测来电号码

Question

每当我使用 BroadcastReceiver 接到来电时，我都会尝试记录电话号码。但是，当我调用我的号码时，我没有收到任何log。这是代码:

AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.abc.broadcast_phone" >

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme" >

        <receiver android:name=".MyPhoneReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" >
                </action>
            </intent-filter>
        </receiver>
        <activity android:name=".MainActivity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

MainActivity.java

    public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Intent intent = new Intent("tuet");
        sendBroadcast(intent);
    }
}

MyPhoneReceiver.java

    public class MyPhoneReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if (extras != null)
        {
            String state = extras.getString(TelephonyManager.EXTRA_STATE);

            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                String phoneNumber = extras
                        .getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                Log.e("DEBUG", phoneNumber);
            }
        }
    }
}

我正在使用 SDK 23 进行编译并且目标也是 Marshmallow，在这种情况下我应该使用运行时权限吗？或者我错过了什么？

EDIT-1

似乎问题只与 Marshmallow 相关，当我降级目标 sdk 版本时，这工作正常:targetSdkVersion 22。

那么，如何调整它以在 SDK23+ 及更高版本中工作？

根据 onCallStateChanged() documentation :

incoming call phone number. If application does not have READ_PHONE_STATE permission, an empty string will be passed as an argument.

READ_PHONE_STATE 是 dangerous permission那一定是 requested at runtime当您根据 Marshmallow Behavior Changes 以 API 23 或更高版本为目标时
