Get forced to wake up

Do you have a problem with your wake up time? Do you often get up too late? You deserve trying this app. Its name is Fajar Warrior Alarm, “just” an alarm app. Actually there are a lot of similar app in the PlayStore. But I choose this one for you, because it’s free (of course the others are free as well though), free of charge and free of ads, that’s the point. I hate apps that show ads so often. And luckily, there is still a generous developer who doesn’t take the user’s freedom to not showing ads in his app. I mean this alarm app.

So, what else that makes it awesome? The challenge to stop the alarm voice. You couldn’t stop the alarm, unless you type the exact same sentence (a hadith) in the input it has. Actually I searched for “math alarm” when I found this app. But unfortunately it contained ads, so I looked for another app instead. And it led me to this Fajar Warrior Alarm.

The idea is similar to the app I wanted in the first place. It won’t stop the noisy alarm until the user type in some expected text. It causes the user to use his/her fully consciousness when typing the answer. And hopefully make the user totally wake up. So curious about it? Just install it and try it on your phone. Good luck.

How to “soft-block” Whatsapp contacts

I have roughly a thousand contacts in my Google account that are synced to my Android. Since they’re saved in Google’s server, I don’t worry if I have to hard reset my phone, for instance. Or the worst thing: it’s lost. So, actually, I would never remove any contact unless it’s really disappeared from this earth. Wkwkwk…

All my contacts, including that don’t have phone numbers

Then comes to my mind a desire not to let a few of them seeing my activities on Whatsapp, in this case status updates. Yeah, maybe I’m the only one who really get paranoid about sort of thing called “online privacy”, actually “fake privacy”, I know.

So, in one day, unintentionally, I found one of my contact had no name on Whatsapp. I rather confused then, what caused it. So thanks to my super curiosity, I kept searching, and eventually I found out a suspect: ASUS Contact Manager, coupled with a setting inside Whatsapp. Take a look these screenshots:

Select only visible group

Un-tick the option to show all contacts

And as the result, only certain people who can see my rapid status updates on Whatsapp. Wkwkwk…

Of course I don’t have to do all those sort of things though, since the one who can see our Whatsapp updates is he/she who also save our phone number in his/her phone. I haven’t tried it on other phone than Zenfone, as I couldn’t find the feature to show/hide contacts. Perhaps you have found it out? Just push your comment below.

KDEConnect not Working in Fedora 23 KDE

I’ve just successfully connected KDE Connect in my Fedora 23 KDE to Android. Just before, I thought it didn’t work in Plasma 5 or broken in Fedora. Since it could not find the Android devices, although they have KDE Connect app installed. But actually, it’s just blocked by firewall config of Fedora.

According to KDE Wiki, the ports for kde-connect need to be opened, i.e 1714-1764. I’ve never thought that such essential part of the desktop environment would be blocked by firewall. So I had no idea to touch firewall config at all. It was until I found a discussion on Reddit about the same problem I had. A user pointing out about Fedora’s firewall that seems blocking kde-connect. But I could see the ports either TCP or UDP have been opened and listened in the firewall config. But then I found out that kde-connect was unchecked in the Services list.

It means that the firewall didn’t allow kde-connect to access the ports it needs. Then I just had to check it, typed password, and voila… my Android device has been found by kde-connect. So now, I can enjoy syncing Android to KDE and playing some stuffs it has.

HTML5 App for Desktop Using Qt WebKit

Qt WebKit HTML5 App
Qt WebKit HTML5 App

It’s been a long time since the last time I wrote about Qt programming. This time I’d like to share my recent activity on developing the desktop version of my Android webapp, Hafal Quran. You can download it from Google Play Store by clicking this badge:
Android app on Google Play

My purpose is that the app can run on most platform. So it led me to choose HTML5 approach. And finally I come up with the app website which everyone can play it on http://hq.amzone.web.id. The Android app is the first platform-specific release of Hafal Quran.

While it looks like already reaches the final version, it actually lacks an important aspect, i.e dis-connectivity. We have to connect to internet to play it. Of course we cannot play it when go offline. So now, I continue its development to the next step: offline mode.

The first development should be focused on the Android version, as the users of mobile devices are the most and growing. But for now, I will make the offline version for desktop first. In this case, I choose to deploy it for Ubuntu Linux distro and the derivatives, particularly Grombyang OS Edu.

Technical overview

I utilize Qt framework for the development because I have some experiences in it. Besides, I decided to use Webkit as the engine of the app. And actually it is part of Qt framework itself. Webkit is the infamous engine for most popular browser, including Safari, Chrome, and even Opera.

But unfortunately, QWebKit module is now being deprecated since Qt 5. And it is now superceded by QWebEngine module. So, for now, I will still use QWebKit module of Qt4.

The drawbacks of using Webkit is probably about the memory usage. Since Qt modules are quite greedy in terms of consuming RAM.


FYI, the Android app was one of 50 apps that were selected at Finding Top50 Local Apps event, which was held by Baidu Indonesia last year.

Debugging android cordova/phonegap apps with Chrome

Check this out! It’s totally awesome tips for Cordova / PhoneGap developers (who have some limitations).

Gonzalo Ayuso | Web Architect

Maybe this post can be obvious but I’ve spoken about it with various developers who don’t know it. It really improves the developing process of cordova/phonegap apps with android at least for me.

With android we can see the log with “adb logcat” but it’s a nightmare. Huge amount of information about our app and also about the operating system. If we’re grep ninjas we can handle it, but as well as I’m not a ninja I prefer another solution. Do you know “chrome://inspect/”? If not, have a look as soon as possible to this tool. We can see the browser’s console of our android in our desktop browser. We only need to enable “usb remote debugger” within our android device and plug with a USB cable. Chrome will detect the remote browser and we can see the console in the same way than we see it when we use…

KDE Connect, Link Your Android to Linux Box

[Versi bahasa Indonesia ada di halaman 2]

Recently, I had a chance to try out KDE Connect. It has KDE in its name, but you can try it on other DEs. Of course with some limitations, i.e Dolphin’s right-click menu for sending files may not available on another file manager. (I haven’t try it on another DE, though). To link your Linux to Android, you need to have KDE Connect app installed on your Android and Linux as well, and connect both devices to the same network.

You can read all about KDE Connect in its developer’s blog: https://albertvaka.wordpress.com. And these are my screenshots of KDE Connect in action:
