Since narrowed the thread toward Android and flagged platform choice as the first decision, here is a current, practical path for starting Android development and where to invest time.

Begin with the official toolchain and language: install Android Studio (Android Studio) and learn Kotlin as the primary language (Kotlin). Follow an official "New Project" template to inspect a running app, then work through targeted codelabs to get hands-on practice (Android Codelabs). Focus first on app fundamentals: app/component lifecycle, intents/navigation, UI building (Jetpack Compose is the modern UI toolkit), and Gradle basics.

Next, learn common architecture and libraries used in production: ViewModel + StateFlow or LiveData for state, Room for local persistence, Retrofit for REST, WorkManager for background work, and coroutines for concurrency. Build small, concrete projects (todo list with Room, REST client with Retrofit, simple image app) to combine these pieces and practice testing and source control.

Practical tips and traps to avoid: prefer a physical device if the emulator is slow or enable hardware acceleration; use Logcat and adb for debugging; test on multiple API levels and screen sizes; reserve C++/NDK work for performance-critical modules (Android NDK). The official docs and codelabs above provide up-to-date examples and sample apps for each topic.

If you read about various mobile OS then you should have some idea of what platform you would like to start/try to work on:

  • Android
  • iPhone
  • Symbian/Qt
  • Java Microedition for BlackBerry or other JME supporting devices

or perhaps having language preference:

  • Java
  • C/C++
  • Python

Well Android is the "in " thing.I know about its SDK and some basics but whould like to know as to what is more worth learning .As far as language preference goes Java and C++ are both fine for me.
