Separate Install Required for Several Elements of the Android SDK
Android Native Development Kit (NDK): C:\Users\\Documents\Embarcadero\Studio\SDKs\android-ndk-17b. #Download android ndk software#
Android Software Development Kit (SDK): C:\Users\Public\Documents\Embarcadero\Studio\21.0\CatalogRepository\AndroidSDK. Java Development Kit (JDK): C:\Program Files\Java\jdk1.7.0_25. Here are the default installed locations of the Android development tools as installed by the RAD Studio installer: The Android development tools ("Android SDKs"), as installed, are accessible using Start | All Programs | Embarcadero RAD Studio Sydney | Android SDKs, as shown here: The following section, #Separate Install Required for Several Elements of the Android SDK, describes the steps for installing the additional required elements of the Android SDK that are not installed by the RAD Studio installer. The installer for RAD Studio installs the current recommended and tested versions of the Android development tools during the RAD Studio installation by default, and adds an Android SDK to the RAD Studio SDK Manager. You Need to Install Part of the Android SDK Yourself 2 Installing the Android Development Tools Without the RAD Studio Installer. 1.1 Separate Install Required for Several Elements of the Android SDK. 1 You Need to Install Part of the Android SDK Yourself. Create an activity called " JNIActivity" with Layout name " activity_jni" and Title " Hello JNI". In this example, we shall create an activity, that calls a native method to obtain a string and displays the string on a TextView.Ĭreate an Android project called " AndroidHelloJNI", with application name " Hello JNI" and package " com.mytest". Study the sample programs provided in " samples" directory, in particular the " hello-jni". The SDK build tools will package the shared libraries in the application's deployable ". Finally, compile and run your application using the SDK tools in the usual way. The build tools copy the stripped, shared libraries needed by your application to the proper location in the application's project directory. Build your native code by running the " ndk-build" (in NDK installed directory) script from your project's directory. Create a " Android.mk" to describe your native sources to the NDK build system. 
Create a sub-directory called " jni" and place all the native sources here.The steps in building an Android NDK app are: The NDK documentation is kept in the " docs" sub-directory. Read the NDK documentation "documentation.html" Android NDK's installed directory. Writing a Hello-world Android NDK Program Step 0: Read the Documentation Include the NDK installed directory in the PATH environment variable.I shall denote the installed directory as. The NDK will be unzipped as d:\myproject\android-ndk-r8.

Unzip the downloaded zip file into a directory of your choice (e.g., d:\myproject).Download the Android NDK from (e.g., android-ndk-r8-windows.zip).

Setting up all the necessary tools for Android programming, such as JDK, Eclipse, Android SDK, Eclipse ADT (Read " How to install Android SDK and Get Started") and (for Windows Users) Cygwin (Read " How to install Cygwin" and " GCC and Make").Native code (in C/C++) is necessary for high performance to overcome the limitations in Java's memory management and performance. The NDK provides all the tools (compilers, libraries, and header files) to build apps that access the device natively. Installing the Native Development Kit (NDK) Android provides Native Development Kit (NDK) to support native development in C/C++, besides the Android Software Development Kit (Android SDK) which supports Java. However, at times, you need to overcome the limitations of Java, such as memory management and performance, by programming directly into Android native interface. Android apps are typically written in Java, with its elegant object-oriented design.
