This mobile app is an example to learn how Blockchain works as an Android app using Java.

Getting started

You can clone or fork this repo and use it freely. If there are build errors, in Android Studio go to Tools -> Android -> SDK Manager and install any available updates. Then go to Build -> Clean Project and finally Build -> Rebuild Project.

Remember, you will need getting the last API version and updates. This project runs with AndroidX and new Material Design, so, if you want to keep this, leave the dependencies as they are.

    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    implementation 'androidx.coordinatorlayout:coordinatorlayout:1.2.0'
}
