![]() The regular Android application launcher is a Java process, so Qt applications have a Java-based entry point. This Java code is compiled under $ANDROID_BUILD_DIR and added to the application bundle. Under $Qt_install_dir/src/android/java/src/org/qtproject/qt/android/bindings/ are the files comprising the Java code of the Android application. The Android Manifest is also used to define Android Services, and custom Android Activities.įor more information about the AndroidManifest.xml, see Android Manifest file documentation. In addition, it's used by the Google Play Store for information on the version code, device support, package name, and lots more. This information is used to customize your application bundle and by the target device to decide which features to enable, the default orientation of the application, and so on. The AndroidManifest.xml file gives detailed meta-information about your application. The main parts of the package templates are described in the following sections. The build directory acts now as the packaging directory, which the application bundle is created from. The previous command copies the application's binaries and resources into the $ANDROID_BUILD_DIR. It is recommended to use Qt Creator or the Makefile created by qmake or CMake to create the application bundle.Īll the steps described here are automatically handled by the build script and the androiddeployqt deployment tool, which are run by Qt Creator by default. jar files, Java code, assets, resources and. so file of your code, as well as all Qt's dependencies needed by your application. In either case, the application bundle is generated from a specific directory structure that contains the. When using AAB, the Google Play store generates optimized APK packages for the devices issuing the download request and automatically signs them with your publisher key.įor more information on the AAB format, see the Android App Bundles. The added convenience of AAB is that you can include all target ABIs in the same bundle without increasing the size of the actual package downloaded by your users. For distribution to the Google Play store, it is recommended to use AAB instead, which has a similar layout. The difference between the two is that APK files can be deployed and executed on a device, whereas AAB is intended to be interpreted by the Google Play store and is used to generate APK files for different device architectures.įor testing the application locally, the APK format is the most appropriate, as this can be uploaded directly to the device and run. Both are ZIP files which follow a predefined directory structure. Android Application BundleĪpplications on Android can be packaged in two ways either as Application Package (APK) or Android App Bundle (AAB). On Windows, that involves pressing Win + R, typing cmd, and then going to the corresponding folder with a command such as CD C:MyFolder, changing MyFolder to the folder name.Note: The androiddeployqt Tool automates this process. Then, open that folder in the command line. If you have an application or game in an App Bundle in AAB format and you want to convert it into an APK that you can install on your mobile, the easiest way is to put in the same folder on your PC the AAB file and Bundletool, to avoid having to include the paths. How to convert an App Bundle (AAB) to APK? It is a JAR file, hence you need to have Java installed on your PC before you can use the tool to convert the AAB file to an APK. In addition, you will need the Bundletool tool, which you can download from GitHub. Android Studio includes Java in its installation and will automatically create your debugging certificate, so it’s a much better option than doing it separately. Sounds complicated, but you will get these last two components if you download and install Android Studio. You will need a computer, Java, and a certificate to sign the applications.
