Cognito Protocol integration for Mycelium Wallet for Android

Building

To build everything from source, simply checkout the source and build using gradle on the build system you need.

• JDK 1.7

Then you need to use the Android SDK manager to install the following components:

• ANDROID_HOME environment variable pointing to the directory where the SDK is installed
• Android SDK Tools 22.6.4
• SDK Platform Tools 19.0.2
• Android SDK build Tools 19.1.0
• Android 4.4.2 (API 19) (at least SDK Platform Rev. 3)
• Android Extras:
  • Android Support Repository rev 5
  • Android Support Library rev 19.1
  • Google Play services for Froyo rev 12
  • Google Play services rev 17
  • Google Repository rev 8

The project layout is designed to be used with a recent version of Android Studio (currently 1.1.0)

Build commands

On the console type:

git clone https://github.com/cognitoprotocol/cognitoprotocol-mycelium-wallet-android-integration.git
cd cognitoprotocol-mycelium-wallet-android-integration

Linux/Mac type:

./gradlew build

Windows type:

gradlew.bat build

• Voila, look into wallet/public/mbw/build/apk to see the generated apk. There are versions for both prodnet and testnet.

Alternatively you will be install the latest version from the Google Play Store.

If you cannot access the Play Store, you will be able to download a copy of the .apk file directly.

Deterministic builds

The Cognito Protocol Wallet for Android does not support reproducible builds at this point. For this reason, you should only use the original Mycelium wallet until reproducible builds are available in the future. Hopefully, they changes will be merged into the main Mycelium branch, making things easier for everyone.

This work on Mycelium reproducible builds is based on WhisperSystems Signal:
