I was really wondering how I can remove repetitive tasks from Android Studio by assigning shortcuts or tags and I found that IntelliJ has Live Templates which I bet that little programmers use. So as an example I wanted when I type the word “tag” within a class the following to be autocompleted:Continue reading “Android Studio Live Templates”
Probably you have seen this type of error when using Genymotion as the Android emulator on which you test your device. This is how the error looks like:
adb server version (32) doesn’t match this client (35); killing…
error: could not install *smartsocket* listener: Address already in use
ADB server didn’t ACK
* failed to start daemon *
There is one simple thing that worked for me. I opened the Settings menu of Genymotion, then ADB tab and selected: Use custom android SDK tools and I set the path to the tools. By default Genymotion uses its built-in tools. After that killing all working emulators and starting them again makes everything work.
Hope I have helped!
Card.io is a card recognition SDK used by PayPal which allows you to easily scan your own credit/debit cards and get information about them in the code.
Using card.io from the source and not from Maven requires you to have the latest Android NDK with which the project will be built. But compiling it with the latest NDK introduces a bug which prevents the library from supporting several phones like Samsung S5, Honor 7 and others.Continue reading “Card.io issue not supporting Samsung S5 and other devices”
There is a very simple solution in Android if you want to have space between components. You can always set margins but you can also use the Space class. You can use it like this:
<Space android:layout_width="1dp" android:layout_height="30dp"/>
The problem is that the library can only be used as a separate module. You can call the card.io Activity and it will return you the results from the detection. But what if you want to embed the detection view inside your app? Well, sadly, there is no fragment for that. But the library is open-source so you can change everything to fit your needs. So let’s start then!Continue reading “Exporting Card.IO as a fragment”

Recently, I got a task to implement face detection for a camera preview we have within our mobile app. So if the app detects a face, a button should be displayed, otherwise – the button should remain hidden.

I found Flux architecture for several months and I have written a couple apps with React & Flux and as an Android programmer also I think that it has to have an implementation.
So I decided to do it. You can check it HERE. I really believe that Flux for Android will be a “groundbreaker” (may be not my try but the whole concept :)).Continue reading “Android Flux Architecture Example”
