Compatibility

• Minimum SDK: 29 (Android 10)
• Target SDK: 37 (Android 17)
• Device Types Supported: Phone and Tablet
• Orientations Supported: Portrait and Landscape

Setup

1. Clone the repository:

   $ git clone https://github.com/bitwarden/android
   

2. Create a user.properties file in the root directory of the project and add the following properties:

   • gitHubToken: A "classic" Github Personal Access Token (PAT) with the read:packages scope (ex: gitHubToken=gph_xx...xx). These can be generated by going to the Github tokens page. See the Github Packages user documentation concerning authentication for more details.
   • localSdk: A boolean value to determine if the SDK should be loaded from the local maven artifactory (ex: localSdk=true). This is particularly useful when developing new SDK capabilities. Review Linking SDK to clients for more details.

3. Setup the code style formatter:

   All code must follow the guidelines described in the Code Style Guidelines document. To aid in adhering to these rules, all contributors should apply docs/bitwarden-style.xml as their code style scheme. In IntelliJ / Android Studio:

   • Navigate to Preferences > Editor > Code Style.
   • Hit the Manage button next to Scheme.
   • Select Import.
   • Find the bitwarden-style.xml file in the project's docs/ directory.
   • Import "from" BitwardenStyle "to" BitwardenStyle.
   • Hit Apply and OK to save the changes and exit Preferences.

   Note that in some cases you may need to restart Android Studio for the changes to take effect.

   All code should be formatted before submitting a pull request. This can be done manually but it can also be helpful to create a macro with a custom keyboard binding to auto-format when saving. In Android Studio on OS X:

   • Select Edit > Macros > Start Macro Recording
   • Select Code > Optimize Imports
   • Select Code > Reformat Code
   • Select File > Save All
   • Select Edit > Macros > Stop Macro Recording

   This can then be mapped to a set of keys by navigating to Android Studio > Preferences and editing the macro under Keymap (ex : shift + command + s).

   Please avoid mixing formatting and logical changes in the same commit/PR. When possible, fix any large formatting issues in a separate PR before opening one to make logical changes to the same code. This helps others focus on the meaningful code changes when reviewing the code.

4. Setup JDK Version 21:

   • Navigate to Preferences > Build, Execution, Deployment > Build Tools > Gradle.
   • Hit the selected Gradle JDK next to Gradle JDK:.
   • Select a 21.x version or hit Download JDK... if not present.
   • Select Version 21.
   • Select your preferred Vendor.
   • Hit Download.
   • Hit Apply.

5. Setup detekt pre-commit hook (optional):

Run the following script from the root of the repository to install the hook. This will overwrite any existing pre-commit hook if present.

echo "Writing detekt pre-commit hook..."
cat << 'EOL' > .git/hooks/pre-commit
#!/usr/bin/env bash

echo "Running detekt check..."
OUTPUT="/tmp/detekt-$(date +%s)"
./gradlew -Pprecommit=true detekt > $OUTPUT
EXIT_CODE=$?
if [ $EXIT_CODE -ne 0 ]; then
  cat $OUTPUT
  rm $OUTPUT
  echo "***********************************************"
  echo "                 detekt failed                 "
  echo " Please fix the above issues before committing "
  echo "***********************************************"
  exit $EXIT_CODE
fi
rm $OUTPUT
EOL
echo "detekt pre-commit hook written to .git/hooks/pre-commit"
echo "Making the hook executable"
chmod +x .git/hooks/pre-commit

echo "detekt pre-commit hook installed successfully to .git/hooks/pre-commit"
