廣播接收器onReceive（）不起作用

Question

在類廣播接收器中的onRecive事件無法正常顯示，但是我沒有在android Monitor中看到日志信息。 我怎么解決這個問題？ 我通過打電話到我使用小米Redmi3s的手機來檢查此問題

類CallReciver：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.graphics.PixelFormat;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.v("tesat", "test");
    }
}

主要內容：

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

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

        <application
                android:allowBackup="true"
                android:icon="@drawable/belarus"
                android:label="@string/app_name"
                android:roundIcon="@mipmap/ic_launcher_round"
                android:supportsRtl="true"
                android:theme="@style/AppTheme">
            <activity android:name=".MainActivity">

            </activity>

            <receiver android:name=".CallReceiver">
                <intent-filter>
                    <action android:name="android.intent.action.PHONE_STATE"/>
                </intent-filter>
            </receiver>
        </application>
<activity
                android:name=".ContentActivity"
                android:label="@string/title_activity_content"
                android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

    </manifest>

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

        <application

            </receiver>

<activity

                android:label="@string/title_activity_content"
                android:theme="@style/AppTheme.NoActionBar">
