java - boot_completed not working on Android 10 Q API level 29

Question

I need help.

I have an application that starts an Intent after the boot that works from Android 6 to Android 9 API level 28. But this code does not work on Android 10 API level 29, Broadcast simply does not receive any events and does not run onReceive on MyClassBroadcastReceiver after the boot. is there any extra permission on the android 10 system or configuration that needs to be done?

Dry part of the example: Manifest:

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

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

<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>
    <service
        android:name="com.softniels.autostartonboot.ForegroundService"
        android:label="My Service">
        <intent-filter>
            <action android:name="com.softniels.autostartonboot.ForegroundService" />
        </intent-filter>
    </service>

    <receiver
        android:name=".StartMyServiceAtBootReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>

</application>

Here the part that doesn't run on Android 10.

public class StartMyServiceAtBootReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
        Log.i("onReceive", "call onReceive ACTION_BOOT_COMPLETED");
        Intent i = new Intent(context, MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

}

I know that this may be old but I have faced the same problem and according to this: https://developer.android.com/guide/components/activities/background-starts

The easiest solution I came up with was simply adding

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

And setting up the receiver:

<receiver
android:name=".BootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

To the manifest.

Receiver code:

@Override
public void onReceive(Context context, Intent intent) {
    if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
//            Intent n =  context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());
 //            n.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | 
 //    Intent.FLAG_ACTIVITY_CLEAR_TASK);
 //            context.startActivity(n);

        Intent myIntent = new Intent(context, MainActivity.class);
        myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(myIntent);
    }
}

Both options work. The only downside I see is that it takes rather a while for app to load (can be up to 10 seconds from my testings)

Leaving this here for other people if they encounter this as well. This only applies to android 10 and up. There is a need to request "Display over other apps" permission

This requires drawing overlay, which can be done with:

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;
        }
