- Mobile application to track car GPS position for SMS based Chinese tracker(s) marketed under the model number A11, ST-901, GT01 and GT09.
- Manage multiple GPS car trackers using SMS communication.
- Set multiple parameter of the tracker (e.g. speed limit, sleep time, password, distance alarm)
- Manage and list messages exchanged with the car tracker.
- Export stored data as file for backup as JSON.
- Dark and bright graphical user interface themes (including maps).
- Mock-up of the ST-901 device that can be used for development testing on the browser.
- Works with any Ionic compatible platform (may have problems on some platforms caused ionic native plugins compatibility).
- May be compatible with other SMS based trackers, but it was only tested with these mentioned above.
- Install Java JDK 8 and Android development SDK, there is no need to install the Android Studio IDE, only the build tools are required.
- Ensure that you have the environment variables
GRADLE_HOME, JAVA_HOME and ANDROID_SDK_ROOT, and have access to java and gradle from the your terminal (or command line in windows).
GRADLE_HOME ...\Gradle\gradle-7.2JAVA_HOME ...\Java\jdk1.8.0_301ANDROID_SDK_ROOT ...\AppData\Local\Android\Sdk
- Install Android SDK Platform 28 tools from the android SDK manager.
- Install NodeJS and NPM and install dependencies
npm install -g @angular/cli
npm install -g @ionic/cli
npm install
npm run start
- The application can be built using Ionic Native for mobile devices using Capacitor.
- Capacitor is a replacement for Cordova developed by the Ionic team, that contains its own plugins for access to native functionalities.
- Install the capacitor CLI globally, and install the required dependencies for Android and iOS development.
# Add a native platform to the project run
npm i @capacitor/ios @capacitor/android
npx cap add android
npx cap add ios
# Check system requirements
npm install -g @capacitor/cli
capacitor doctor android
# Add new plugins to the application
npm install --save @capacitor/toast
npx cap sync
