Overview

AI Use Case

ai-edge-gallery.apk: Mobile (Android) GenAI Chat app which uses Hugging Face Integration to discover and download various on-device (local) LLM (LiteRT .tflite / .litert .task models). The app apk, built using Google AI-Edge Portal, is installed to demonstrate automation of test runs and presentation of results (TTFT, decode speed, latency) to benchmark performance among LiteRT-optimized models. App activities tested include:

  • Ask Image: Obtain an image of a homework problem and ask questions about it: descriptions, solve problems, or identify objects.
  • Prompt Lab: Upload a pdf and ask questions: summarize, rewrite, generate code, or use freeform prompts
  • AI Chat
  1. CAUTION: Do a full Backup before proceeding with system-level configurations below.

Prerequisite System Dependencies

  1. Install XCode Command Line Tools: 
    
xcode-select --install
  2. Use Homebrew to install tools used for Android dev : 
    
brew install ant
brew install maven
brew install gradle
brew doctor

    Install Java

  3. Install Temurin (an anagram of “runtime”), an open-source, high-performance Java runtime based on OpenJDK, produced by the Eclipse Foundation’s Adoptium Working Group. Install the latest: 
    brew install --cask temurin

    Alternately, install a specific version such as 21:

    brew install --cask temurin@21
  4. Verify: https://jdk.java.net/24/ 
    java -version
    openjdk version "23.0.1" 2024-10-15
OpenJDK Runtime Environment Zulu23.30+13-CA (build 23.0.1+11)
OpenJDK 64-Bit Server VM Zulu23.30+13-CA (build 23.0.1+11, mixed mode, sharing)
  5. Confirm: 
    which java
    /usr/bin/java
  6. VIDEO: What is Temurin?
    • jadx - decompiles APK to Java source code
    • apktool - decodes resources and rebuilds APKs

    Install Android Platform Tools

  7. To avoid the need to hard-code path, instead of manual https://developer.android.com/studio/install Alternately, track down the specific version to download, such as:
    android-studio-2024.3.2.15-mac_arm.dmg 
    brew install cask android-platform-tools
  8. Confirm: 
    which adb
    /opt/homebrew/bin/adb

    The above avoids the need to define PATH in .bash_profile or .zshrc, such as:

    echo 'export ANDROID_HOME=/Users/$USER/Library/Android/sdk' >> ~/.zshrc
echo 'export PATH="$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools"' >> ~/.zshrc

    This also avoid need to create a symbolic link (essentially a shortcut) for the adb executable in folder /usr/local/bin which is one of the default locations where Terminal looks for command line tools:

    sudo ln -s ~/Library/Android/sdk/platform-tools/adb /usr/local/bin

    Install Android Command Line Tools

  9. Run per https://developer.android.com/tools description of the Adroid Debug Bridge (adb) https://android-sdk-platform-tools-adb.en.softonic.com/mac?ex=RAMP-3252.3#google_vignette 
    adb version
    Android Debug Bridge version 1.0.41
Version 36.0.0-13206524
Installed as /opt/homebrew/bin/adb
Running on Darwin 24.5.0 (arm64)
  10. Install Android CLI: 
    brew install --cask android-commandlinetools
  11. Verify: 
    which sdkmanager
    /opt/homebrew/bin/sdkmanager
  12. Confirm 
    sdkmanager --version
    19.0
  13. Refresh your shell profile (or restart your terminal app): 
    source ~/.zshrc
or
source ~/.bash_profile

    .Android folder

    REMEMBER: $HOME/.android is the default folder Android uses to store configuration metadata.

  14. See what’s in the folder: 
    ls -al $HOME/.android
    total 56
drwxr-x---@  10 johndoe  staff   320 Jun 19 01:05 .
drwxr-x---+ 104 johndoe  staff  3328 Jun 19 01:05 ..

-rwxr-xr-x@   1 johndoe  staff   171 Jun 19 01:05 modem-nv-ram-5554

    Install Android SDK

  15. To avoid “.android/repositories.cfg could not be loaded” error, create a blank file: 
    touch ~/.android/repositories.cfg

    The equivalent of this for Powershell on Windows 10:

    New-Item C:\Users\$username\.android\repositories.cfg -type file
  16. Use Homebrew to install the Android Software Development Kit (sdk): 
    
brew install --cask android-sdk

    This takes several minutes. Just wait while “Installing Cask android-sdk”.

    Native Development Kit

  17. AVOID: Use Homebrew to install the Android Native Development Kit (ndk): 
    
brew install --cask android-ndk

  18. Install HAXM for blazing fast emulators. Check out the “Configuring VM Acceleration on Mac” section at:

    http://developer.android.com/tools/devices/emulator.html

    Edit Terminal start-up CLI

  19. Edit your ~/.bash_profile to update environment variables: 
    export ANDROID_SDK_ROOT="/usr/local/share/android-sdk"      
export ANT_HOME=/usr/local/opt/ant
export MAVEN_HOME=/usr/local/opt/maven
export GRADLE_HOME=/usr/local/opt/gradle
export ANDROID_HOME=/usr/local/opt/android-sdk
export ANDROID_NDK_HOME=/usr/local/opt/android-ndk
  20. Update your paths (bonus points to a better solution to the hardcoded build tools version): 
    export PATH=$ANT_HOME/bin:$PATH
export PATH=$MAVEN_HOME/bin:$PATH
export PATH=$GRADLE_HOME/bin:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/build-tools/19.1.0:$PATH

    Version Updates

  21. Periodically run these commands again to ensure you’re staying up to date: 
    
brew update
android update sdk --no-ui

    There might be an issue with brew update and the android-sdk formula.

    Android Studio

    Alternately, you can install and use Eclipse, IntelliJ, or your other favorite IDE.

    Alternately, download the dmg from https://developer.android.com/studio/install.html

    Alternately, see http://macappstore.org/android-studio/ for manual download. https://classroom.udacity.com/courses/ud808/lessons/4216368924/concepts/43072785890923# is a video mini-course done April 2015 about that approach.

    • https://github.com/caskroom/homebrew-cask/blob/master/Casks/android-studio.rb

    But the easiest way is:

  22. To inspect app structure, resources, and permissions during development or security analysis of APK File, install the APK Analyzer (built into Android Studio) 
    
brew install --cask android-studio
  23. Notice in the install response: 
    ==> Linking Binary 'studio' to '/opt/homebrew/bin/studio'

    That means you have an option to open the app by simply:

    
studio

    Alternately, because the app contains a space in its name:

    open $HOME/Applications/Android Studio.app
  24. Click “Open” if the “app downloaded from the Internet” appears.
  25. Click “Don’t send”.
  26. Accept.
  27. Emulator.
  28. Finish to watching “Downloading Components”.

  29. Finish.

  30. Notice new repositories are created to: 
    /Users/johndoe/StudioProjects

    Install custom apk app on macOS

  31. Create a folder 
    cd "$HOME/bomonike"
git clone https://github.com/bomonike/ai-edge-gallery
APP_FOLDER_PATH="$HOME/bomonike/ai-edge-gallery"
cd "$APP_FOLDER_PATH"
ls -al
  32. Download .apk file (to Downloads folder) Yields file ai-edge-gallery.apk.cpgz
  33. Alternately, use “The Unarchiver” or Keka archive tools 
    APP_FILE_PATH="$APP_FOLDER_PATH/apk/"
mkdir -p "$APP_FILE_PATH"
cd "$APP_FILE_PATH"
APK_FILE_NAME="ai-edge-gallery.apk"
# FIXME: mv "$HOME/Downloads/$APK_FILE_NAME" "$APP_FILE_PATH"
# Respond with A for all:
unzip "$APK_FILE_NAME" -d "$APP_FILE_PATH"
ls -al
    • Creates files AndroidManifest.xml, *.properties, *.dex, etc.
    • Creates folders assets, com, google, lib, META-INF, okhttp3, org, res
  34. Use Adroid Debug Bridge (adb) https://android-sdk-platform-tools-adb.en.softonic.com/mac?ex=RAMP-3252.3#google_vignette ``` adb devices
    • daemon not running; starting now at tcp:5037
    • daemon started successfully List of devices attached
        adb install “$APK_FILE_NAME” adb: no devices/emulators found ```
  35. Consider files in the repo:
    • model_allowlist.json lists LLM models

    Use Android Studio app

  36. Launch the Android Studio DMG file.
  37. Drag Android Studio into the Applications folder, then launch Android Studio.

  38. Choose whether to import previous Android Studio settings, then click OK.

    https://developer.android.com/studio/intro/studio-config

  39. Complete the Android Studio Setup Wizard, which includes downloading the Android SDK components that are required for development.

  40. See https://developer.android.com/tools/releases/platform-tools Select Mac to download https://dl.google.com/android/repository/platform-tools-latest-darwin.zip
  41. Use 
    cd /usr/local/tmp/platform-tools;  ls
adb          etc1tool  hprof-conv  make_f2fs           mke2fs       NOTICE.txt         sqlite3
billday.txt  fastboot  lib64       make_f2fs_casefold  mke2fs.conf  source.properties
 
/usr/local/tmp/platform-tools $ ls -l ../platform-tools-latest-linux.zip 
-rw-r--r-- 1 chronos chronos 7472902 Dec 20 22:44 ../platform-tools-latest-linux.zip
 
/usr/local/tmp/platform-tools $ ./adb --version

    Use it

  42. Pinch 4 fingers together over the touchpad and type “An” to select “Android Studio”.

  43. Select “Do not import settings.”
  44. Custom.
  45. Choose the Default or darker Dracular theme (which uses less battery, I’m told).
  46. Check “Android Virtual Device”, then Next for /Users/wilsonmar/Library/Android/sdk
  47. 2 GiB on a 16 GiB machine.
  48. Finish. It takes several minutes for Downloading and install.
  49. Provide password to HAXM installation changes.
  50. When “Silent install Pass!” appears, press Finish.

  51. See

    Emulate app

  52. Start an emulator: Launch one from Android Studio’s AVD Manager
  53. Wait for boot: Make sure the emulator is fully booted before running ADB commands

  54. Check if running: Use adb devices to list connected devices
