无法获得权限:"android.permission.SET_ALARM"

Question

我做了一个Android应用程序,并使用AlarmManager和Broadcast Receiver来获取本地通知.但我的Receiver类根本没有被调用.我回溯了这个问题,发现我的应用程序无法获得'SET_ALARM'权限.请在下面找到截图.

因此,为了交叉检查权限问题,我在MainActivity.java中添加了以下代码,以检查应用程序是否能够获得权限.我发现它无法获得请求SET_ALARM权限.请在下面找到代码.

MainActivity.java

package com.dileepmanuballa224.alarm_test;

import android.Manifest;
import android.app.AlarmManager;
import android.content.pm.PackageManager;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;


public class MainActivity extends AppCompatActivity {

    AlarmManager am;
    @RequiresApi(api = Build.VERSION_CODES.M)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if(ContextCompat.checkSelfPermission(this, Manifest.permission.SET_ALARM)!= PackageManager.PERMISSION_GRANTED){
            Log.d("Perm check:SET_ALARM", "Permission Denied");
            requestPermissions(new String[]{Manifest.permission.SET_ALARM},1);
        }else{
            Log.d("Perm check:SET_ALARM", "Permission Exists");
        }

        if(ContextCompat.checkSelfPermission(this, Manifest.permission.INTERNET)!= PackageManager.PERMISSION_GRANTED){
            Log.d("Perm check:INTERNET", "Permission Denied");
            requestPermissions(new String[]{Manifest.permission.SET_ALARM},1);
        }else{
            Log.d("Perm check:INTERNET", "Permission Exists");
        }

    }
    }

清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.dileepmanuballa224.alarm_test">

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

有谁可以帮我解决这个问题.

您在Manifest中声明的权限不是权限的正确值,权限的实际值是:

<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />

看到这个,没有这样的权限,这是它拒绝权限以及不请求它的原因,将权限更改为上述值,一切都会正常工作.

如果你想验证那么:

if(ContextCompat.checkSelfPermission(this, Manifest.permission.SET_ALARM)!= PackageManager.PERMISSION_GRANTED){
            Log.d("Perm check:SET_ALARM", "Permission Denied");
            requestPermissions(new String[]{Manifest.permission.SET_ALARM},1);
        }else{
            Log.d("Perm check:SET_ALARM", "Permission Exists");
        }

如果你要检查它的值Manifest.permission.SET_ALARM,你会看到它会在"com.android.alarm.permission.SET_ALARM"这里看到:
