Building an app that will make you rich and change the world is only one motivation; others include learning to code, building tools that you can use yourself or even just having fun and impressing others.
Maybe you have a great idea and you want to build a prototype, maybe you just want to learn to program for Android, maybe it is part of a school or college course, or maybe you are just curious.
Whatever the motivation, building Android apps can be fun and rewarding. In this tutorial we go through the steps needed to build your very first Android app.
But before we start, it is worth mentioning some of the other resources we have related to writing Android apps. Included in the download are the Software Development Kit, with all the Android libraries and bits that you need to develop an app; and the Android emulator, so that you can initially test you app on your PC without needing to install it on a real device.
Oracle will not be posting any updates of Java SE 7 to its public download sites and it is suggested that users move to Java 8, however at the moment Android Studio requites Java 7. This could change in the future. During the install you will need to configure how much memory to reserve for the Android emulator.
The emulator runs Android in a kind of virtual machine, as an Android phone with an Intel processor. However to run this virtual machine the emulator needs to allocate some memory.
The installation program will recommend how much memory to reserve and it is probably best to accept the default. However, be aware that the combination of Android Studio, Java, and the emulator can be quite memory hungry, and your PC will slow to a crawl unless you have lots of RAM.
When you first run Android Studio it will perform some initialization including downloading and installing the latest Android SDK. This can take several minutes, you will just need to be patient.
When everything has been downloaded and whenever you subsequently start Android Studio you will see a menu which allows you to start a new project, open an existing project, import a project, and so on. If you are an independent developer or a hobbyist, enter your domain name.
This can take several minutes especially if it is the first time you have created a project. The default workspace for the IDE is split into three main parts excluding the toolbars etc.
On the upper left is the project tree. So instead we are going to add a few little things, not much, but enough to get you started and give you a taste of Android app development!
The project tree The project tree holds all the different files and resources that are needed to build your Android app. If you are familiar with writing simple programs in Java, C, Python, etc you might think that everything will be contained in just one or possibly two files.
However Android app development is a little more complex, however this initial complexity is actually very useful once you start to write your app in earnest.
It is an XML file with information about the app including its name. One of the most common things you will add to this file is the list of permissions needed by the app. Under that folder you will find MainActivity. This is the entry point into your app and for our example app this is the only Java file that we will need.
There are two ways to edit this file. The advantage of this system is that if a string is used multiple times it can be changed in just once place.A basic introduction to the world of Python on Android.
Learn to write scripts in QPython, access native phone features and even build APKs! It has been possible to write mobile applications in Python for a couple of years; there have been various iOS and Android libraries and apps that allow you to run and write Python on your mobile device.
May 30, · DEVELOPING ANDROID APPS COMPLETELY IN PYTHON. If your goal is to not write Java, then you are mistaken. The NDK still requires binding within Java. The last I checked, these were not generated for you by most or any tools. That the Go mobile tool does is novel. This requirement appears to be some sort of problem for those using Python for.
As a Python lover and Android programmer, I am sad to say this is not really a good way to go. There are two problems. One problem is that there is a lot more than just a programming language to the Android development tools.
A lot of the Android graphics involve XML files . Writing your first Android app – everything you need to know building Android apps can be fun and rewarding. If you are familiar with writing simple programs in Java, C, Python, etc you. Is there a way to run Python on Android?
[closed] I've been playing around with Kivy this past week attempting to write a game. Their main developers were very quick to answer questions on IRC however if you've programmed a GUI before Kivy will make you say WTF quite a bit.
I have tried them both and can firmly say that they make.
