How do I start my app on startup?

Question

I tried using the sample code in this link but it seems outdated and it did not work. So what changes do I have to make and to what files to have my app start automatically

Answer 1

For Android 10 there is background restrictions.

For android 10 and all version of android follow this steps to start an app after a restart or turn on mobile

Add this two permission in Android Manifest

Add this in your application tag

Add this class to start activity when boot up

public class BootReciever extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    if (Objects.equals(intent.getAction(), Intent.ACTION_BOOT_COMPLETED)) {
        Intent i = new Intent(context, SplashActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
 }}

We need Draw overlay permission for android 10

so add this in your first activity

 private fun requestPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!Settings.canDrawOverlays(this)) {
            val intent = Intent(
                Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + this.packageName)
            )
            startActivityForResult(intent, 232)
        } else {
            //Permission Granted-System will work
        }
    }
}
