But foldables and wearables introduce their own UI challenges and developers may not always have access to them, so Android Studio now offers developers a single resizable emulator that allows them to quickly test an app on different form factors.įor WearOS specifically, the Android team is introducing a new way to create declarative user interfaces with the beta launch of the Compose UI SDK. The idea behind Google’s “modern Android development” is, after all, that developers can learn how to write applications for one form factor and then apply that to all of the other ones. Given that Google today announced both its first in-house smartwatch and a new tablet, it’s maybe also no surprise that Android Studio is adding additional support for large-screen devices, including tablets and foldables, as well as wearables. “This is a first big step where we’re bringing the Firebase experience into Android Studio.” “A pain point for a developer today is that while they’re getting really good insights from Crashlytics, to see what errors are happening and the events that led up to them, in order for them to debug and reproduce some of the errors and fix them, they often need to switch to a different tool,” Firebase product lead Francis Ma explained. The idea here, of course, is to allow developers to do more of their work in a single application without having to switch contexts. Using the new App Quality Insights windows, developers can now see their stack traces right in their IDE and even see which lines of codes are likely to cause a crash. Now, however, developers will be able to do things like add new functions and tweak the user interface and see the effect of those changes in real time.Īlso new in Android Studio is built-in support for Firebase’s Crashlytics, Google’s crash reporting service. He noted that Android Studio already featured Live Literals, which allowed developers to change small individual values. Install tools 1.1.Sean McBreen, who leads developer experience for Android at Google, noted that this is something developers have been requesting for a long time, given that it will allow developers to speed up their cycle times without having to wait to test their changes. This tutorial is tested only in Ubuntu 14.04 LTS x86_64. The app will have proguard enabled, and use JNI feature. In this article, I will walk through how to build a simple Android App from command line. I have to admit though, that you will need an IDE to build a serious app. I did this, to understand how Android app works and because I prefer command line over heavy IDEs. But I decided to do it without Android Studio nor Eclipse. To build an Android app, the recommended tool is Android Studio. Where is the exact revision number such as 24, 25.2.5. But you still can download older sdk from these links:
UPDATE : “android create project” command is removed from newer sdk tools (since 25.3.0).
