Installation

Install Android Emulator

Windows

1. Install Java: Download and install Java from here. Make sure you set the JAVA_HOME environment variable. You can check if Java is installed correctly by running the command java --version in any command prompt window, which should display the installed Java version.
2. Install Android SDK Command line tools:
   • Download the Command line tools and extract them.
   • Move the extracted cmdline-tools directory to a new directory of your choice, for example, android_sdk. This new directory will be your Android SDK directory.
   • Inside the extracted cmdline-tools directory, create a new subdirectory named latest.
   • Move the contents of the original cmdline-tools directory (including the lib directory, bin directory, NOTICE.txt file, and source.properties file) to the newly created latest directory. Now, you can use the command line tools from this location.
3. Install platform tools: Run the following command in the command prompt:

android_sdk\cmdline-tools\latest\bin\sdkmanager.bat "platform-tools" "platforms;android-33"

4. Download the Android image (API-level: 33):

android_sdk\cmdline-tools\latest\bin\sdkmanager.bat "system-images;android-33;google_apis_playstore;x86_64"

5. Create an Android Virtual Device (AVD):

android_sdk\cmdline-tools\latest\bin\avdmanager.bat create avd -n avd33 -k "system-images;android-33;google_apis_playstore;x86_64"

6. Launch the AVD:
   • For the Android GUI:

   android_sdk\emulator\emulator.exe -avd avd33 -memory 512 -partition-size 1024 -no-snapshot-load
   

   • For headless mode (no Android GUI):

   android_sdk\emulator\emulator.exe -avd avd33 -memory 512 -partition-size 1024 -no-snapshot-load
   

7. Test ADB connection:

android_sdk\platform-tools\adb.exe connect 127.0.0.1:5555
android_sdk\platform-tools\adb.exe devices

8. Run the following command to install the ATX application on the emulator:

python3 -m uiautomator2 init

Linux

The installation process for Linux is similar to Windows, with some additional steps:

1. Install Java and set the environment variables:

export JAVA_HOME=/home/user_name/java/jdk-xx.x.x.x  # Replace with your actual JDK installation directory
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

2. Follow the same steps as Windows for installing Android SDK Command line tools, platform tools, and creating an AVD.
3. Launch the AVD:
   • For the Android GUI:

   android_sdk\emulator\emulator -avd avd33 -memory 512 -partition-size 1024 -no-snapshot-load
   

   • For headless mode (no Android GUI):

   android_sdk\emulator\emulator -avd avd33 -memory 512 -partition-size 1024 -no-snapshot-load
   

4. Test ADB connection:

android_sdk\platform-tools\adb connect 127.0.0.1:5555
android_sdk\platform-tools\adb devices

5. Run the following command to install the ATX application on the emulator:

python3 -m uiautomator2 init

Additional setup

1. Please mannuly setup your Google account
2. Turn off APP auto-upgrade in Google Play

Troubleshoot

1. If you encounter the error "packaging.version.InvalidVersion: Invalid version: ''", you may need to enable uiautomator2 in the emulator:
   • On the emulator, open the ATX app
   • Click on "Start uiautomator"
2. Cannot set_text in TextView or EditView Check Settings -> System -> Language & Input -> Physical Keyboard -> turn on Use on-screen keyboard
3. Black screen https://www.cnblogs.com/yongdaimi/p/17464095.html android_sdk\emulator\emulator.exe -avd avd33 -memory 512 -partition-size 1024 -no-snapshot-load
