Flutter app BOOT_COMPLETED receiver doesn't work

Question

There have been many questions like this before, and I've tried to implement the answers but it doesn't work on Android 11. I want my flutter app will be started/opened automatically after booting was completed.

this is my receiver MainActivityReceiver.kt

package com.mypackage

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

class MainActivityReceiver: BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        if (intent.action == Intent.ACTION_BOOT_COMPLETED) {
            val i = Intent(context, MainActivity::class.java)
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
            context.startActivity(i)
        }
    }
}

and I added some code on AndroidManifest.xml

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

<receiver
            android:enabled="true"
            android:exported="true"
            android:name="com.myPackage.MainActivityReceiver"
            android:permission="android.permission.RECEIVE_BOOT_COMPLETED">

            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.QUICKBOOT_POWERON" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>

  </receiver>

EDIT

I found https://stackoverflow.com/a/63250729/11445944, but how to implement it on flutter?. How to add this code on flutter MainActivity.kt

if (!Settings.canDrawOverlays(getApplicationContext())) {
            Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
            Uri uri = Uri.fromParts("package", getPackageName(), null);

            myIntent.setData(uri);
            startActivityForResult(myIntent, REQUEST_OVERLAY_PERMISSIONS);
            return;
        }

I've added it on my MainActivity.kt

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        if (!Settings.canDrawOverlays(getApplicationContext())) {
            val myIntent = Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION)
            val uri: Uri = Uri.fromParts("package", getPackageName(), null)
            myIntent.setData(uri)
            startActivityForResult(myIntent, REQUEST_OVERLAY_PERMISSIONS)
            return
        }
    }

And I got the error on build

[   +2 ms] e: project_path/app/MainActivity.kt: (32, 5): 'onCreate' overrides nothing
[  +24 ms] e: project_path/app/src/main/kotlin/package/MainActivity.kt: (32, 47): Unresolved reference: Bundle
[   +7 ms] e: project_path/app/src/main/kotlin/package/MainActivity.kt: (34, 14): Unresolved reference: Settings
[   +3 ms] e: project_path/app/src/main/kotlin/package/MainActivity.kt: (35, 35): Unresolved reference: Settings
[   +3 ms] e: project_path/app/src/main/kotlin/MainActivity.kt: (38, 46): Unresolved reference:
REQUEST_OVERLAY_PERMISSIONS

SOLVED

The error was gone after I import 2 lines code

import android.os.Bundle
import android.provider.Settings

and don't forget to initialize var REQUEST_OVERLAY_PERMISSIONS = 100. Now my app run automatically after booting was completed on Android 11.

For Flutter you need to add in manifest file :

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

then onCreate of MainActivity.kt file

 if (!Settings.canDrawOverlays(getApplicationContext())) {
            val myIntent = Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION)
            val uri: Uri = Uri.fromParts("package", getPackageName(), null)
            myIntent.setData(uri)
            startActivityForResult(myIntent, REQUEST_OVERLAY_PERMISSIONS)
            return
        }

and rest will be same for receiver.

Edit.....

For Android - 11 changes. you need to open settings for that system overlay permission:

startActivityForResult(
    Intent(
        Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
        Uri.parse("package:$packageName")
    ),
    REQUEST_OVERDRAW_PERMISSION_CODE
)

Starting from Android 10 (API 29), there are restrictions on directly starting activities from the background in order to minimize user interruptions. See if your application starts on bootup if you use API 28 or below. As a possible compromise, you can display a high priority notification which opens the application when the user clicks it.

You'd have to implement a `BroadcastReceiver` which will pick up when the phone boots up. In the `onReceive` method of the receiver, place the code which you currently have in your `onCreate` method. – Stéphan van Biljon Jan 27 '22 at 11:37
