### Building the Bitcoin Wallet for Android on Fedora on the command line as a fresh non-root user ###
# This uses sdkmanager instead of the GUI Android SDK IDE
# These instructions may need to be slightly modified for newer versions of the tools required to build the target application. 

# 1. Install javac and related tools: dnf install java-1.8.0-openjdk-devel
#    TODO: This may not be enough tools... look into this later.
# 2. Create a new non-root user and login
# 3. Download these packages and put them into /tmp
#    https://services.gradle.org/distributions/gradle-2.10-bin.zip    from  https://gradle.org/gradle-download/
#    https://dl.google.com/android/repository/tools_r25.2.3-linux.zip from https://developer.android.com/studio/index.html
# 4. Unpack tools

cd ~/
unzip /tmp/gradle-2.10-bin.zip
mkdir android_sdk
cd android_sdk
unzip /tmp/tools_r25.2.3-linux.zip
cd tools/bin
# Use sdkmanager to update itself
./sdmanager --update
# Exit and enter the directory again
cd ../bin/

# Install tools needed to build Bitcoin Wallet for Android
./sdkmanager 'build-tools;25.0.1' 'extras;android;m2repository' 'ndk-bundle' 'platform-tools' 'platforms;android-15' 'platforms;android-25' 'tools'

# Add these to ~/.bashrc then restart your shell
export PATH=~/gradle-2.10/bin:$PATH
export ANDROID_HOME=~/android_sdk
export ANDROID_NDK_HOME=~/android_sdk/ndk-bundle

# Restart your shell so the environment variables take effect

git clone https://github.com/bitcoin-wallet/bitcoin-wallet.git
cd bitcoin-wallet/
gradle clean build

### Build Automation Note: Build requires X DISPLAY to work, may require fake Xephyr server to automate a headless build process
