git clone --recursive https://github.com/meganz/android.git
Install in the system the Android NDK 21 (latest version tested: NDK r21d, version number: 21.3.6528147).
Export NDK_ROOT variable or create a symbolic link at ${HOME}/android-ndk to point to your Android NDK installation path.
export NDK_ROOT=/path/to/ndk
ln -s /path/to/ndk ${HOME}/android-ndk
Install NDK r21d by Android Studio following these instructions (pay attention to the bottom-right Show Package Details checkbox to display the available versions. Latest version tested: NDK r21d, version number: 21.3.6528147)
Export NDK_ROOT variable or create a symbolic link at ${HOME}/android-ndk to point to your Android NDK installation path.
Default macOS path: export NDK_ROOT="/Users/${USER}/Library/Android/sdk/ndk/21.3.6528147"
ln -s /path/to/ndk ${HOME}/android-ndk
Export ANDROID_HOME variable or create a symbolic link at ${HOME}/android-sdk to point to your Android SDK installation path.
export ANDROID_HOME=/path/to/sdk
ln -s /path/to/sdk ${HOME}/android-sdk
Export ANDROID_HOME variable or create a symbolic link at ${HOME}/android-sdk to point to your Android SDK installation path.
Default macOS path: export ANDROID_HOME="/Users/${USER}/Library/Android/sdk/")
ln -s /path/to/sdk ${HOME}/android-sdk
Export JAVA_HOME variable or create a symbolic link at ${HOME}/android-java to point to your Java installation path.
You can use the path in Android Studio, which you can find in Preferences > Build, Execution, Deployment > Build Tools > Gradle > Gradle JDK (default)
export JAVA_HOME=/path/to/jdk
ln -s /path/to/jdk ${HOME}/android-java
Export JAVA_HOME variable or create a symbolic link at ${HOME}/android-java to point to your Java installation path.
You can use the path in Android Studio, which you can find in Preferences > Build, Execution, Deployment > Build Tools > Gradle > Gradle JDK (default)

ln -s /path/to/jdk ${HOME}/android-java
- Download the link https://mega.nz/file/F0YThaQR#FgoSW-XuxwHVr-9SNmVcP_JWG8B0Q6ogT9By3fEiEDc, uncompress it and put the folder
webrtcin the pathsdk/src/main/jni/megachat/.Be mindful that the download link of webrtc may varies over time, please keep it in line with the one written in build.sh
Before running the SDK building script, install the required packages. For example for Ubuntu or other Debian-based distro:
sudo apt install build-essential swig automake libtool autoconf cmake ninja-build
ATTENTION: After upgrading ExoPlayer to 2.18.1, we need to use CMake version 3.22.1
Then install CMake version 3.22.1 in Android Studio > Tools > SDK Manager > SDK Tools > CMake.
After installation, add below line in ~/.bashrc
export PATH="/home/$USER/Android/Sdk/cmake/3.22.1/bin:$PATH"
You will need to source your ~/.bashrc or logout/login (or restart the terminal) for the changes to take effect. To source your ~/.bashrc, simply type:
source ~/.bashrc
Before running the SDK building script, install the required dependencies via HomeBrew:
Except below tools, please do not use HomeBrew to install other tools, according to SysAdmin's advice.
brew install bash gnu-sed gnu-tar autoconf automake cmake coreutils libtool swig wget xz python3
Then reboot MacOS - to ensure newly installed latest bash (v5.x) overrides default v3.x in PATH
Then edit PATH env (Please make sure the gnu paths are setup in front of $PATH):
- For Intel chip, add below lines in
~/.zshrc
export PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
- For Apple chip, add below lines in
~/.zshrc
export PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"
export PATH="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH"
ln -s /opt/homebrew/bin/python3 /opt/homebrew/bin/python
ATTENTION: After upgrading ExoPlayer to 2.18.1, we need to use CMake version 3.22.1
Then install CMake version 3.22.1 in Android Studio > Tools > SDK Manager > SDK Tools > CMake.
You have to tick checkbox 'Show Package Details' to display this specific version. After installation, add below line in ~/.zshrc
export PATH="/Users/${USER}/Library/Android/sdk/cmake/3.22.1/bin:$PATH"
Build SDK by running ./build.sh all at sdk/src/main/jni/. You could also run ./build.sh clean to clean the previous configuration.
IMPORTANT: check that the build process finished successfully, it should finish with the Task finished OK message. Otherwise, modify LOG_FILE variable in build.sh from /dev/null to a certain text file and run ./build.sh all again for viewing the build errors.
In case of an error (seen in the log file mentioned) due to licenses not accepted, you can read and accept the licenses with the sdkmanager command-line tool (if you downloaded them)
/path-to-cmdline-tools/bin/sdkmanager --sdk_root=$ANDROID_HOME --licenses
Download the link https://mega.nz/#!1tcl3CrL!i23zkmx7ibnYy34HQdsOOFAPOqQuTo1-2iZ5qFlU7-k, uncompress it and put the folders debug and release in the path app/src/.
Open buildSrc/src/main/kotlin/mega/privacy/android/build/Util.kt, change method shouldUsePrebuiltSdk() to below.
fun shouldUsePrebuiltSdk(): Boolean = false
// System.getenv("USE_PREBUILT_SDK")?.let { it != "false" } ?: trueOpen settings.gradle.kts, change method shouldUsePrebuiltSdk() to below:
fun shouldUsePrebuiltSdk(): Boolean = false
// System.getenv("USE_PREBUILT_SDK")?.let { it != "false" } ?: trueNote: You need to occasionally redo this section to make sure latest analytics library is used.
-
Download and build Mobile Analytics source code.
git clone --recursive https://github.com/meganz/mobile-analytics.git cd mobile-analytics git checkout main ./gradlew assembleRelease -
Copy below generated libraries to root of MEGA code
shared/build/outputs/aar/shared-release.aaranalytics-core/build/outputs/aar/analytics-core-release.aaranalytics-annotations/build/outputs/aar/analytics-annotations-release.aar
-
Modify MEGA code to depend on local AAR files
- Search
implementation(lib.mega.analytics)in whole project, and replace all occurrences with below code. Note you may need to add a..to the path if thebuild.gradle.ktsis in a subproject.// implementation(lib.mega.analytics) implementation(files("../shared-release.aar")) implementation(files("../analytics-core-release.aar")) implementation(files("../analytics-annotations-release.aar"))
- Search
- in root
build.gradle.kts, comment out below codes.id("mega.android.release") - in
settings.gradle.kts, comment out below codeandmaven { url = uri("${System.getenv("ARTIFACTORY_BASE_URL")}/artifactory/mega-gradle/megagradle") }resolutionStrategy { eachPlugin { if (requested.id.id == "mega.android.release") { useModule("mega.privacy:megagradle:${requested.version}") } } }
Open the project with Android Studio, let it build the project and hit Run.
- In Android studio, open the SDK manager (Or through Settings>Appearance & Behaviour>System Settings>Android SDK)
- Go to the SDK Tools tab
- Check the "Show package details" box
- Expand the CMake section in the list
- Select 3.22.1
- Click "OK"
- Add the following to your PATH:
export PATH="/Users/{USERNAME}/Library/Android/sdk/cmake/3.22.1/bin:$PATH" - Retry the build
To use the geolocation feature you need a Google Maps API key:
-
To get one, follow the directions here: https://developers.google.com/maps/documentation/android/signup.
-
Once you have your key, replace the "google_maps_key" string in these files:
app/src/debug/res/values/google_maps_api.xmlandapp/src/release/res/values/google_maps_api.xml.
