SDK Platform-tools Contains platform-dependent tools for developing and debugging your application. These tools support the latest features of the Android platform and are typically updated only when a new platform becomes available.
These tools are always backward compatible with older platforms, but you must be sure that you have the latest version of these tools when you install a new SDK platform. It includes an android. In order to build an Android app, you must specify an SDK platform as your build target. System Images Each platform version offers one or more different system images such as for ARM and x The Android emulator requires a system image to operate.
You should always test your app on the latest version of Android and using the emulator with the latest system image is a good way to do so. Sources for Android SDK A copy of the Android platform source code that's useful for stepping through the code while debugging your app.
These are a great resource to browse Android app code. The API Demos app in particular provides a huge number of small demos you should explore. Android Support A static library you can include in your app sources in order to use powerful APIs that aren't available in the standard platform. For example, the support library contains versions of the Fragment class that's compatible with Android 1.
Virtual devices for all shapes and sizes Android Studio comes pre-configured with an optimized emulator image. The updated and streamlined Virtual Device Manager provides pre-defined device profiles for common Android devices.

It gives mobile software developers the opportunity to manually fix, text, profile, debug, and update their own software within the same platform. This toolset includes a debugger, an emulator, Application Programming Interfaces APIs , sample projects with source code as well as the required libraries to build Android apps.
These tools are platform-independent and are essential in creating Android apps, regardless of the version you are working for. Most importantly, it comes with an emulated virtual device that is fully functional that allows you to test out your work in progress. Now that you have a basic knowledge about the toolset, you should also understand that even if it contains almost everything you need to create and further develop an Android software, it still needs the support of other important command-line tools such as Platform tools, and the Android Emulator, in order for you to get started.
It works along with Build tools for encryption, security, and file size purposes. One of the tools included in this group is the Android Debug Bridge adb. It can be used to install an Android app file on any of your devices and allows you to access additional shell tools like bmgr and logcat. This emulator is a QEMU-based device-emulation tool that allows you to debug and test your apps in an actual Android runtime environment even without using any physical devices.
Running the emulator will require you to have a system image, an additional tool to your toolset. Each platform version contains the supported system images. This is where Android Studio comes in, it allows you to compile and edit your code, or test your app before releasing it on Google Play.
On the Choose Install Location page, enter the destination folder, such as C:Androidandroid-sdk , and then click Next. Make a note of where you installed the files. You will need this information when you configure JDeveloper Because the emulator in later versions requires more memory and is slower, use Android 4.

Although these builds are subject to morebugs, they do get tested and we want to offer them so you can try newfeatures and provide feedback. This channel is not recommended forproduction development. If you'd like to try one of the preview channels Canary, Dev, or Beta while still using the Stable build for your production Android projects, youcan install both side by side. The Delete Unused Android Studio Directories dialog then displays locations, sizes, and last-modified times of these unused directories and provides an option to delete them.
Once downloaded, you can findeach package in the directory indicated as the Android SDK Location ,shown in figure 2.

Pending removals areindicated with a red cross. To update the selected packages,click Apply or OK , then agree to anylicense agreements.
Projects created with Android Studio 3. If you're using an older project, you must manually add Google's Maven repository to your build.
