Omni-Notes

Omni-Notes is a note taking open-source application aimed to have both a simple interface while keeping smart behavior. This application expands on the generic note taking features of other basic applications and allows for users to attach image and video files, use a variety of widgets, tag and organize notes, search through notes, and customize the applications UI.

The project was inspired by the absence of such applications compatible with old phones and old versions of Android. It aims to provide an attractive look and follow the most recent design guidelines of the Google operating system that is not currently avaialbe for older devices.

Build

Watch the following terminal session recording on how to compile distributable files or follow the instructions below

Build instructions:

• Enter your computer's terminal
• Clone the application by using the link to the repository (https://github.com/federicoiosue/Omni-Notes), this will take a couple minutes
• Enter the Omni-Notes folder using the command $cd Omni-Notes
• Check that the branch is up to date by using the command $git status
• Enter the command $export ANDROID_HOME=/home/fede/Android/Sdk (for Windows $set ANDROID_HOME=/home/fede/Android/Sdk)
• Enter the command $./gradlew assemble
• Allow a couple minutes for the application to build.
• View the outputs of the build using the command $ls -l omniNotes/build/outputs/apk

To be sure that build environment is fully compliant with the project the following command creates a container with all the needed tools to compile the code:

cd {project-folder}; rm local.properties; docker rm android-omninotes; docker run -v $PWD:/workspace --name android-omninotes tabrindle/min-alpine-android-sdk:latest bash -c "mkdir -p ~/.android && touch ~/.android/repositories.cfg && yes | sdkmanager --update &>/dev/null && cd /workspace && ./gradlew clean build --stacktrace -Dorg.gradle.daemon=true -Pandroid.useDeprecatedNdk=true"

Test

To execute all tests included into the project connect a device or emulator, then run the following command:

./gradlew testAll

Testing Pyramid

To speedup the development more levels of testing are available following the testing pyramid approach, each type test requires more time than the previous one.

Unit Tests

./gradlew --stacktrace test

Integration Tests

./gradlew --stacktrace -Pandroid.testInstrumentationRunnerArguments.notAnnotation=androidx.test.filters.LargeTest connectedAndroidTest

UI Tests

./gradlew --stacktrace -Pandroid.testInstrumentationRunnerArguments.annotation=androidx.test.filters.LargeTest connectedPlayDebugAndroidTest

Notice that in this case I specified a single flavor to run tests on. This could be a useful and faster approach when you're testing specific flavor features.
