Safe Android App

Goal

The Safe aims to provide all users with a convenient, yet secure way to manage their funds and interact with decentralized applications on Ethereum. Transactions are secured by on-chain multi-factor-authentication. This is achieved by using the Safe smart contracts. They are the successor of the broadly trusted Gnosis Multisig Wallet smart contracts).

Setup

Infura

The Json RPC depends on Infura. You need to get an API key and create a file named project_keys with the following contents:

INFURA_API_KEY=<YOUR_PROJECT_ID>

Replace <YOUR_PROJECT_ID> with the project id that you get from Infura. You can find this project id at Projects -> Settings -> Keys -> PROJECT ID on the Infura Website.

Firebase

The Safe Android App uses Firebase and your build will fail if you don't have the google-services.json file. To get this file, you need to create a Firebase project at https://console.firebase.google.com/ and add at least one Android application. If you didn't change the applicationId in app/build.gradle you need to create an app with the package name io.gnosis.safe.debug to be able to build a debug app. You can find the latest google-services.json file in the Project Settings -> General

After downloading the file, copy it to the app module folder.

Code Style

Make sure that you apply the Kotlin coding conventions and use the style schema in this repo with Android Studio.

Also always add newlines at the end of files. This can be enforced by Android Studio. For this enable Editor -> General -> Ensure line feed … (Under the “Others” section).

CI Setup

Travis is used for continuous integration. It requires the google-services.json and debug-upload.jks. These need to be encrypted into a single file using the travis cli.

tar cvf secrets.tar gnosis-upload.jks app/google-services.json app/src/rinkeby/google-services.json app/src/release/google-services.json
travis encrypt-file secrets.tar
