If yourĪPP_PLATFORM is set lower than android-14, android-14 is used instead. Target in the NDK is now Android 4.0 (android-9). LOCAL_CPP_FEATURES := rtti exceptionsĭon't update NDK version 15 if your apps should run on android-9Īndroid 2.3 (android-9) is no longer supported. However, I could not even find any clue so far. I also guessed that one of flags or features I need in c may cause this. It seems NDK still supports higher than or equal to level 3. I tried to find out why at NDK guides, although I still have no idea. Why does NDK stop supporting Android levels(3-13) lower than android-14? Android NDK: WARNING: APP_PLATFORM android-14 is Do they read these forums Why my Unity ver. This opens the Browse For Folder dialog to use for navigating to the location of the Android SDK. Using minimum supported versionĪndroid-14. New issue NDK is missing a 'platforms' directory. Please be aware that Unity 2019.3.0a7 has the same issue as mentioned above - it still wants NDK r19 (64-bit) (133), latest r19 from Google won't work, older ones won't work, except for the one that's linked here. To set the location of the Android SDK, click the ellipsis () button to the far right of Android SDK Location. Replaced the " JNIActivity.I have used Android NDK for years, however, recently, I saw the message below when I built CPPs using ndk-build(ndk version 15)Īndroid NDK: android-9 is unsupported. 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 possible directories that AGP locates NDK are: The related available features that could affect which version of NDK to use are: Out of the NDK path configuration channels, ndkVersion feature added in version 3. 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.
