For android building level

"For android building level"








You can now use Eclipse to build and debug the software. Build Your First Android App Learn more, save more. It is different from default settings for OpenCV. Configure Qt and skip unsupported modules:. Other Settings Remove any data from meshes that is not required by the material applied to them (tangents, normals, colors, UV). I've been wanting to get Wasp running on Android and Gonk (the low level Android layer of Firefox OS) for debugging and small applications. Please note that settings from wincfg. Or if make fails with Java related messages, then make sure your version of python is a Windows app instead of the cygwin one, such as ActiveState Python v2. In RhoStudio, you can double-click on your application’s build. It is recommended that you use this to setup a cmake build directory. In order to test, go into the "Run" settings for your project. Building Qt 5 for Android These are the current build instructions to get to the point where you can deploy a Qt app to an Android device using Qt Creator. The android-8 in the platform makes the standalone toolkit generate applications for FroYo and above (See STABLE-APIS. Also be aware that android-cmake also sets configuration-specific compiler and linker flags. The Run Configurations window appears. If you are using wincfg. The result is a waspvm-android-arm-linux stub in the stubs directory. If you want to compile OpenCV for emulator or older device, or want to build with NEON support please read the Android targets section for instructions. Then you can run: 8. Using RhoHub Alternatively, you can create the device builds with RhoHub. You should now see a build directory, that is ready to be made That will build most of the OpenCV modules, except for those that don't make sense on android - gpu. You should always keep your Build Tools component updated by downloading the latest version using the Android SDK Manager. NEON is a SIMD instruction set that must be specifically programmed for (there is a compiler option to auto-vectorize code to work with NEON, but that would completely rule out compatibility with devices that don't have NEON, and may have negligible benefit [1] ) I'm thinking the best idea will be compile "armeabi" and "armeabi-v7 with VFPV3", as this should allow pretty good compatibility. If not set then initialized from NDK_CCACHE environment variable. It should succeed this time. But if you still facing problems with assembler then try to upgrade your CMake to version newer than 2. To add to your path (temporarily; doing it permanently varies according to the OS), use the following command in the terminal window: Otherwise, the problem is that you need to configure cmake properly; the default values are for paths on my own system, you'll need to configure them. Console application is much more convenient for development, debugging and performance optimization stages. Then open Windows console ( cmd. Under "Deploy Configuration", check the "Use Qt libraries from local device" option. Run: This will create the apk. Linux (Ubuntu) and Mac OS (10. Possible target names are: armeabi - ARMv5TE based CPU with software floating point operations; armeabi-v7a - ARMv7 based devices with hardware FPU instructions (VFPv3_D16); armeabi-v7a with NEON - same as armeabi-v7a, but sets NEON as floating-point unit; armeabi-v7a with VFPV3 - same as armeabi-v7a, but sets VFPv3_D32 as floating-point unit; armeabi-v6 with VFP - tuned for ARMv6 processors having VFP; x86 - IA-32 instruction set mips - MIPS32 instruction set arm64-v8a - ARMv8 AArch64 instruction set - only for NDK r10 and newer x86_64 - Intel64 instruction set (r1) - only for NDK r10 and newer mips64 - MIPS64 instruction set (r6) - only for NDK r10 and newer ANDROID_NATIVE_API_LEVEL - level of android API to build for. For example you can be searching for your documentation generator. If debugging, as noted above, you must use a device. RhoHub is a cloud based service that integrates with RhoStudio to allow building and packaging apps for all platforms. If you don't have the environment variables saved on your account, start necessitas' QtCreator in a terminal window that does. Reading the Log File with RhoStudio After you run your application in RhoStudio, your application log file, rholog. On Windows, you must start QtCreator for a MinGW shell, otherwise it won't detect the MinGW cmake generator and you'll be quite stuck. You can build Qt applications against any API level you wish, As long as it is equal to or higher than 13. Use the following values for emulator: When all variables are set run the commands Connect to your device with adb tool from Android SDK and run the script If you can see HelloAndroid. This will hopefully have information on what happened. The following commands will do that (replace the path in the export with the path of the ndk on your system): But cmake will fail. The list of possible values depends on the NDK version and will be printed by toolchain file if an invalid value is set. Difference from traditional CMake Folowing the ndk-build the android-cmake supports only two build targets : So don't even try other targets that can be found in CMake documentation and don't forget to explicitly specify Release or Debug because CMake builds without a build configuration by default. Follow the onscreen instructions. NDK allows libraries for different EABIs to coexist in the same package, and will choose the appropriate one for the device. Stellarium will not run in the Android emulator. Building for android-L is possible only when it is explicitly selected. Remove cygwin from your PATH. To configure cmake, either run in place of cmake in the above command, or edit the CMakeCache. Also select the "Deploy local Qt libraries" radio button. Then click the Run button. You can even send the bytecode compiler itself to be loaded and run in the interpreter to get a full system on the target. Debug with Eclipse Create a new project, choose Android project, and choose "Create project from existing source". ANDROID_TOOLCHAIN_NAME - the name of compiler toolchain to be used. Also, note that the signing must be done from Unity’s player settings - using jarsigner will not work. If not set then android-cmake will search for the most recent version of supported NDK in commonly used locations; ANDROID_ABI - specifies the target Application Binary Interface (ABI). By default android-cmake selects the most recent version of GCC which can build for specified ANDROID_ABI. Get Qt 5: 5. If make fails with message similar to Then you are probably using cygwin tools instead of their native ports. To use a specific version of the Build Tools in your application project: In the root folder of your application project, find the build. This path should not have tailing slash; Add path to cmake and make tools to PATH environment variable. Add path to your make. The 'clean' process doesn't remove the stub file we created in the previous step which still allows us to do android Wasp programs. This sample is configured for emulator. This produces a waspvm-linux-x86_64 stub in my stubs directory. Available for NDK r7 and newer. See the RhoHub tutorial for more details. NDK_CCACHE - path to ccache executable. The most important Android-specific parameters are (some will be set by default unless you first built in that directory without the toolchain): OPENGL_MODE Set to ES2 for Android devices BUILD_STATIC_PLUGINS Currently should be set to 0 as not all plugins support OpenGL ES2 GUI_MODE Mobile You can also use Desktop to use the Desktop UI, if you so choose. NOTE: If you are using the GYP_DEFINES environment variable, it will override any settings in this file. To generate a standalone toolchain to build Wasp I used: Replace NDK_ROOT with the path to the Android SDK and STK_ROOT with the destination where you want the standalone toolkit installed. If building for x86 or MIPS devices, change target_arch to "ia32" or "mipsel". To build with Ninja you need: Ensure you are using CMake newer than 2. Here is a list of capabilities you can add to the capabilities section in your application build. It should be possible to hook gdb into Eclipse or QtCreator to allow GUI debugging. MOSREF for example: Running on Android Running these executables on Android involves pushing them to somewhere writeable on the phone. ANDROID_NATIVE_API_LEVEL leave it at default (android-8); this is the lowest API we can use, so using this allows the greatest compatibility. NOTE: Shadow builds are currently broken. Change BUILD_DIR path and ANDROID_ABI CMake parameter. We may want to test this to see if that's true and whether there's a performance benefit "armeabi-v7a with NEON" enables NEON and VFPV3 instructions. It'll probably be handy to have a script do most of the setup for this use. One of the nice features of Wasp is being able to have a minimal interpreter running on a platform and send byte code from another system to that interpreter which is loaded and run. Building this for Android using the standalone toolkit is straightforward: This configures libevent to be built using the ARM compilers in the standalone toolkit and to install the resulting libraries in the same install location as the toolkit. By doing a 'clean' followed by a 'make' on the host we'll clean out the Android build files and rebuild what's needed for the host. Creating the host Wasp programs To easily create Wasp programs for different platforms we'll need versions of them for the host we are running on. Because we're using Qt, it's unlikely we'll need the extra features the higher levels give us Build and deploy Once all the parameters are set up, run cmake again. Value of ANDROID_NDK CMake variable; Value of ANDROID_NDK environment variable; Search under paths from ANDROID_NDK_SEARCH_PATHS CMake variable; Search platform specific locations (home folder, Windows "Program Files", etc). Now, we want to build a debug apk without assets (see Android port ; even if you wanted to include assets in the apk, they can't currently be used). At this point you should be able to create a project and configure it for the Android kit. This option allows to select between different GCC and Clang versions. The android-cmake recommends you to use find_host_package and find_host_program macro defined in the android. Either clear it or set it to the values above before running gclient runhooks. If you want to build this sample for ARM-v7a device (with or without NEON support) you need to edit cmake_android. First of all you need an Android SDK. You can also edit the build. So will surely find libz. Then connect your Android device to your computer with a USB cable. The bytecode for an application is appended to the stub file and the result made to be executable. Second, you need OpenCV compiled for your device. This makes it easy for other applications to find and link with the library. So android-cmake configures CMake to search in Android-specific paths only and ignore your host system locations. Implies - frtti - fno-exceptions for NDK r7 and newer. Available for NDK r7 and newer. You can open and read rholog. Implies - fno-rtti - fno-exceptions for NDK before r7. Implies - frtti - fno-exceptions for NDK r7 and newer. If it fails, look in the directory it's created and edit the CMakeCache. If not specified then set to armeabi-v7a. This line in QtActivity. For general information about Qt 5 for Android, please visit the wiki for that. Running on the Android Simulator with RhoStudio To run on the Android simulator, select Android in Platform, Simulator in Simulator type, and enter the name of the AVD in AVD name. Building the Wasp stub for Android A Wasp VM stub file is used for generating Wasp applications. You will see a list of capabilities you can check to activate for your application. The default API level depends on the target ABI: android-8 for ARM; android-9 for x86 and MIPS; android-21 for 64-bit ABIs. Running on an Android Device with RhoStudio To run on an Android device, first set up your device as shown in the Android documentation for Using Hardware Devices. By default, these capabilities are NOT enabled. There is no ready script for Windows platform, you need to build OpenCV step by step: When script finishes you will have OpenCV compiled. To build the Android stub: To build we define the correct version of the build programs to compile for ARM and set the architecture and OS to stop the build system from picking up the host system version of these. The output is set as awasp which is our executable for running on Android. Debug with QtCreator To import the project into QtCreator These instructions may be somwhat outdated, especially as they pertain to Windows, as some issues with QtCreator have been fixed in the beta version of Necessitas. In QtCreator, open the CMakeLists. You also need to export an environment variable for the location of the NDK. If you rebuild Stellarium but don't change the assets or translation files, you won't need to recopy this directory; otherwise, you will. Passing in - G"Unix Makefiles" appears to work) To get it to build, deploy, and run the code, you can just add build commands to the project as described above ( make install. We can use a similar command for producing Android versions of the other Wasp programs. More instructions for using Bazaar and Launchpad can be found in the Bazaar and Launchpad documentation. To run your application in the Android emulator, run the following command: You can adjust the settings of the Android emulator from your application’s build. You're on your own. This page has a lot of overlap with another page about building Qt for Android. If you have a rooted Android device (or a Firefox OS device) you can push them pretty much anywhere. If your projects depend on older versions of the Build Tools, the SDK Manager allows you to download and maintain separate versions of the tools for use with those projects. Open the file and specify the Build Tools version by adding a buildToolsVersion property to the android section: The sections below provide notes about releases of the Build Tools. May want to investigate that at some point. To determine which revisions of the Build Tools are available in your SDK, refer to the Installed Packages listing in the Android SDK Manager. Now you should be able to resume in Eclipse and in gdb, and debug as usual. This is a Unix console which may be used as a template for development. For example, the following entry will restrict installing your application on any Android OS prior to 3. The error message may mention something that's not in your PATH. The Mobile GUI is a work in progress. A description of the general Player Settings can be found here. Note: These are build instructions for building Qt for Android on Linux or Mac OS X. In the Run Configurations window, select Android in Platform, and Device in Simulator type. Example values are: aarch64-linux-android-4. Silently degrades to gnustl_static if not available. Implies - fno-rtti - fno-exceptions for NDK before r7. For cross-compiling on Windows, this is currently possible under cmd. To develop and do interesting things on the phone you really need the Wasp mod files and the stub files copied over: MOSREF Android drone It's simple now to create a MOSREF drone that runs on Android. Pop into IRC and let me know, or toss out an email to the mailing list. By default, the Android SDK uses the most recent downloaded version of the Build Tools. Set up minimal Android SDK API level The minimal API level supported by Rhodes is 4 (Android 1. This results in a vesion of gcc and libraries that can be run from conventional makefiles and configure scripts. Can be set either to full name (example: android-8 ) or a numeric value (example: 17 ). Building and Running Your Android Application from the Command Line From the command line, navigate to your application directory. Troubleshooting Building on Windows First of all cygwin builds are NOT supported and will not be supported by android-cmake. This is a collection of CMake scripts that may be useful to the Android NDK community. By having stubs for various operating systems and architectures you can create executables specific to them easily. API Compatibility Level Publishing Settings Note that for security reasons, Unity will save neither the keystore password nor the key password. Sync to experimental Android branch The code currently resides in a personal branch. In the following windows, choose "MinGW Makefiles" or "Unix Makefiles" as the generator, put in any cmake commands you need (the toolchain one from above may be all), and run it. To generate the Wasp interpreter and other programs: Exit out of the repl with (exit) and there will be a wasp. Enjoy the fast native multithreaded build :) But if you still want to stick to old make then: Get a Windows port of GNU Make: Android NDK r7 (and newer) already has make. Standalone Toolkit Building Wasp for Android requires generating a standalone toolchain from the Android NDK. Read Android ABIs to know how to build OpenCV for emulator. This option nearly matches to the APP_ABI variable used by ndk-build tool from Android NDK. Linux (Ubuntu) and Mac OS (10. Now we can make a version of wasp for Android: The waspc command takes a stub file (defined by the platform or stub argument) and appends the bytecode resulting from the compilation of the Wasp lisp code given as an argument. Make sure the MOSREF console has a stubs directory containing the Android stub then create the drone as: Copy the created drone1 onto the phone and run it: Now on the console you can see the drone on the phone: The load command shown above loads and compiles the Wasp lisp file on the host and sends the compiled bytecode to the drone on the phone. Then click Virtual devices. The default is gnustl_static. You can use it: to avoid installing SDKs locally to quickly get you up and running for building and packaging for platforms that are not supported by your development computer, for example building iPhone apps from your Windows PC. Start the Qt Creator you built earlier. This is the basis of how MOSREF works where the drone gets sent code to run from the console system. Configure Environment Variables You need to set up environment variables for the following: $JAVA_HOME (e. They're supposed to be paths on the Android device though, not your system. However sometimes you need to locate a host package even when cross-compiling. Please note that this template does not relate to a particular application: it is used for every Android application build. Available for NDK r7b and newer.
