Taking into account the versatility offered by the Android operating system, Android SDK provides a streamlined solution for putting together software applications compatible with Android devices, whether you're a less experienced or skilled developer.
The easiest solution is to install everything from the Android Studio package. Android Development Tools (ADT) is a plugin for the Eclipse IDE that is designed to give you a powerful, integrated environment in which to build Android applications. The SDK can be installed as a standalone product but this means that you have to separately take care of the dependencies. To be able to install Android SDK, you have to first set up the newest version of JDK. These can be used to support new and existing Android features such as logcat, bmgr and Android Debugging Bridge. The platform tools are useful for unlocking the device bootloader too, as well as for flashing the device with a new system image, connecting and rooting them using fastboot, adb and others. The SDK platform along with the platform and build utilities can be selected or deselected for installation from the Android SDK manager. Users can also take advantage of an emulator and all the libraries required for building tools optimized for Android.
Note: Before you can download code, you will need an IBM Registration ID. Customers who are considering development and testing on Version 11 should use the IBM Semeru Runtimes Open Edition. Samples projects complete with source code and tutorials can be used by first-time Android developers to get a better idea of how everything works. The package includes the Eclipse platform with the IBM SDK, Java Technology Edition, Version 8 and is suitable for 32-bit and 64-bit on Windows systems. Build, compile, test and debug Android apps using this SDK It can also be used with the sdkmanager command-line utility as well as with the help of Eclipse and Java Development Kit (JDK). The software development kit is part of Android Studio and the SDK tools package. Released by Google, Android SDK provides developers with all the necessary tools, components and libraries for creating, compiling, testing and debugging mobile applications compatible with the Android operating system. For example, when the SDK Tools are updated or a new version of the Android platform.
Note: Android SDK can be download via Android Studio or using the sdkmanager command-line utility, which is included in the SDK tools package. The Android SDK is composed of modular packages that you can download separately using the Android SDK Manager.
