Hi everybody, i have found a cool website to built Android applications in a split second. Yeah in seconds you can learn how to code for your android device. Since i am not a fan of Apple's products i will not talk about IOS stuffs. This is built by MIT and its one of the best product i found to develop for Android devices. Within few days i learnt the basic and later built an wonderful app to control my Bluetooth modules. This is how the coding looks like. Look how easy it is, just like a puzzle. For advance projects like these you need to refer to Android guide to know how some phone modules work with the command. Here is some pictures of my app. This a good and useful software for kids and schools. Instead teaching bullshit we can teach this to increase mind activities / practical involving others to learn coding for there daily use. For example i built this app to switch on/off light, you can built an app to monitor your plants health. This test is done...
