应用程序因 Permission Denial 崩溃：不允许发送广播 android.intent.action.SCREEN_ON

Question

I am new to the broadcast receiver and implemented broadcast receiver dynamically as shown below

IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
    filter.addAction(Intent.ACTION_SCREEN_OFF);
    BroadcastReceiver mService=new StarterOnBoot();
    registerReceiver(mService,filter);

in manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.autostartter">
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<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/Theme.AutoStartTer">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.AutoStartTer.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".RuntimePermission"
        android:label="@string/app_name"
        android:theme="@style/Theme.AutoStartTer.NoActionBar">
    </activity>
</application>

</manifest>

I have also created a button, by clicking who send broadcast manually as shown below

view.findViewById(R.id.button_second).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent=new Intent();
            intent.setAction(Intent.ACTION_SCREEN_ON);
            MainActivity.instance_main.sendBroadcast(intent);
        }
    });

Broadcast Service is

package com.example.autostartter;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

import java.util.logging.Handler;

public class StarterOnBoot extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Broadcast Hit", Toast.LENGTH_SHORT).show();
    if(intent.getAction().equals(Intent.CATEGORY_HOME))
    {
        Intent i=new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
    if(intent.getAction().equals(Intent.ACTION_USER_UNLOCKED))
    {
        Intent i=new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
    if(intent.getAction().equals(Intent.ACTION_SCREEN_ON))
    {
        Intent i=new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
    if(intent.getAction().equals(Intent.ACTION_USER_PRESENT))
    {
        Intent i=new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
    if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
    {
        Intent i=new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}
}

the broadcast works properly when the user unlocks the screen. However, when I click on the button the application crashes with the following exception

I have also acquired overlay permissions

Please ignore any mistake not directly related to this problem.

Answer 1

Add this permission to the Manifest file.

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