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");
        }

    }
    }
