Some aren't relevant since the code is there to support older Android APIs while using the newer APIs when targeting those versions like the ones in src/main/java/org/medicmobile/webapp/mobile/util/Vibrator.java. But most of the others are relevant and we should probably do something about them.

Describe the improvement you'd like

• Shut Gradle/Javac about the deprecated APIs we intentionally support and provide alternatives for more recent Android versions
• Provide supported alternatives for the deprecated APIs we rely on

Describe alternatives you've considered
