Coinomi Wallet

Our goal is to support every cryptocurrency with an active development team. Store all the best cryptocurrency through a single app, without sacrificing security. Private keys are stored on your own device. Instead of having one backup file for every coin, you get a master key that can be memorized or stored on a piece of paper. Restore all wallets from a single recovery phrase.

TODOs:

• Create instrumentation tests to test a signed APK

Building the app

Install Android Studio. Once it is running, import coinomi-android by navigating to where you cloned or downloaded it and selecting settings.gradle. When it is finished importing, click on the SDK Manager . You will need to install SDK version 21.

NOTE If you are attempting to build on a Lollipop emulator, please ensure that you are using Android 5..* armeabi-v7*. It will not build on an x86/x86_64 emulator.

Contributions

Your contributions are very welcome, be it translations, extra features or new coins support. Just fork this repo and create a pull request with your changes.

For new coins support read this document. Generally you need:

• Electrum-server support
• Coinomi core support
• A beautiful vector icon
• Entry to the BIP44 registry that is maintained by Satoshi labs

Releasing the app

To release the app follow the steps.

1. Change the following:

• in strings.xml app_name string to "Coinomi" and app_package to com.coinomi.wallet
• in build.gradle the package from "com.coinomi.wallet.dev" to "com.coinomi.wallet"
• in AndroidManifest.xml the android:icon to "ic_launcher" and all "com.coinomi.wallet.dev." to "com.coinomi.wallet."
• remove all ic_launcher_dev icons with rm wallet/src/main/res/drawable*/ic_launcher_dev.png
• setup ACRA and ShapeShift

2. Then in the Android Studio go to:

• Build -> Clean Project and without waiting...
• Build -> Generate Signed APK and generate a signed APK. ... and now you can grab yourself a nice cup of tea.

3. Test this APK (TODO: with instrumentation tests).

For now test it manually by installing it adb install -r wallet/wallet-release.apk

This one is in the TODOs and must be automated because it will be here that you take a break ;)

4. Upload to Play Store and check for any errors and if all OK publish in beta first.

5. Create a GIT release commit:

• Create a commit with the log entry similar to the description in the Play Store
• Create a tag with the version of the released APK with git tag vX.Y.Z <commit-hash>
