7 steps to create an Android application with Python
I will show you how to create an android application in python.
Python is a versatile programming language, but you can’t create Android apps with it. However, by creating an APK file, which is an Android executable file, you can run the application on Android.
Here, I will introduce 7 steps to create an Android application in Python, so please use it as a reference for creating an application.
Creating an Android application with Python Step 1: Install Python
When creating an Android application with Python, let’s install Python with the port command.
Since an error occurs when creating the APK file, set the version to “Python3.6.7”.
Also, let’s pass to “/opt/local/bin”, “/opt/local/Library/Frameworks/Python.framework/Versions/3.6/bin”.
Creating an Android application with Python Step 2: Install Kivy
Install Kivy to create Android apps in Python.
Install all the tools that depend on Kivy. At this time, there are cython versions that do not match depending on the Kivy version, so be careful.
After installing Kivy, write a program to display “Hello World” and check its operation.
Building an Android app with Python Step 3: Install Buildozer
If you want to create an Android application with Python, let’s install Buildozer itself.
Install Buildozer and upgrade to the development version. Once “Buildozer-0.38.dev0” is installed, continue to install tools to make Buildozer work properly.
CrystaX NDK
Install CrystaX NDK to run Buildozer
When you start Builderozer, it will use Google’s NDK by default, but you will get an error if you leave it as it is. Therefore, let’s install CrystaX NDK (crystax-ndk-10.3.2-darwin-x86_64.tar.xz).
Java Development Kit
Install Java Development Kit.
The latest version of the Java Development Kit is not supported by Buildoze, so you need to install version 8.
To install 8, the active version will be displayed after installation, so change “OpenJDK 8” or “Java SE 8” to active.
Build an Android app with Python Step 4: Launch Buildoze
When creating an Android application with Python, start Buildozer first.
Buildozer configuration files let’s create a working directory and place main.py and other related program files.
Build an Android app with Python Step 5: Build an APK file with Buildoze
When creating an Android application with Python, let’s create an APK file with Buildozer.
Create “myapp-0.1-debug.apk” in the bin directory of your working directory. However, when starting for the first time, there are cases where an error occurs due to lack of tools, so avoid it by installing the sh library or curl.
Creating an Android app with Python Step 6: Move the AKP file to Android
If you build an Android app with Python, let’s move the APK file to Android.
Since it is necessary to put Android into developer mode, press the build number several times in “Settings”, “System”, “About phone” to enter developer mode.
In addition, turn on “System” in “Device Information”, turn on “Developer Options”, turn on USB debugging, connect to PC with USB cable and transfer files.
Creating an Android application with Python Step 7: Checking the application launch on the Android device
When creating an Android application with Python, let’s check the startup of the application on the Android terminal at the end.
After the created application has been transferred, let’s check the startup of the application on the Android side. If it can be started successfully, the work is completed.
