Hi!

Hi,

How hidden is it ?
How did you hide it in the first place ?
Where is it hidden ?

Mikeeeeee

In desktop, the app is first expanded, then I hidden it by pressing the hidde button, in Android, it is hidden by pressing the center button.

Mikeeeeee

But this is all for widgets. How do I do this for QML?

jsulm

@Mikeeeeee What about https://doc.qt.io/qt-5/qml-qtquick-window-window.html#raise-method ?

Mikeeeeee

It is wirk in Windows

            show()
            raise()

But what me need doing in Android?

GrecKo

You can't do that on Android

Mikeeeeee

But the alarm clock works on Android. So I can do it. But how? When collapsing the app stops, how do I make it work collapsed?

Mikeeeeee

Maybe its can help?

jsulm

@Mikeeeeee Yes, you have to use services if you want to run something in background on iOS/Android.

Mikeeeeee

There is no "android:process"in my Manifest. Where should I specify "android:process"? Are there any examples?

Mikeeeeee

I do this in Manifest

    <service
            android:exported="false"
            android:enabled="true"
            android:name=".MyService"
            android:process=".MyService">
    </service>

Me need inclute QTimer or class in MyService. How can I do this?
May be somewhere me need use this?

startService(getApplicationContext(), MyService.class);

jsulm

@Mikeeeeee I suggest you first read this: https://doc.qt.io/qt-5/android-services.html

"Me need inclute QTimer or class in MyService. How can I do this?" - like always maybe? Include QTimer header and use it...

Mikeeeeee

The documentation shows a lot of code parts, but it is not clear where they should be in the code. Can I view the entire sample project?

you may want to look at this article about "How to create an Android service using Qt"

Mikeeeeee

@Pablo-J-Rogina Thanks. Q do you know where to get a project with sample code?

Your reply shows that you didn't even bother to have a look at the article I linked to...

Mikeeeeee

I looked at the article and looked at the code on the git, but everything is not very clear. It is unclear why the server is needed. And whether this code is enough to start the service or whether you need something else. And if I run it, my app will also work in hide mode?

// java file android/src/com/kdab/training/MyService.java
package com.kdab.training;

import android.content.Context;
import android.content.Intent;
import org.qtproject.qt5.android.bindings.QtService;

public class MyService extends QtService
{
    public static void startMyService(Context ctx) {
        ctx.startService(new Intent(ctx, MyService.class));
    }
}

Mikeeeeee

if i to do this, then the code is not compiled

<application ...
public class MyBroadcastReceiver extends BroadcastReceiver {
    
        @Override
    
        public void onReceive(Context context, Intent intent) {
    
            Intent startServiceIntent = new Intent(context, MyService.class);
    
            context.startService(startServiceIntent);
    
        }
    
    }
