Aab to apk extractor tool12/14/2023 There are also strings that contain additional libraries that should be loaded and JAR files which should be included in the class path. In particular, the application name and the name of the application binary can be specified here. The strings.xml file contains strings used by the AndroidManifest.xml and by the deployment mechanisms. This file can be found at $Qt_instal_dir/src/android/java/res/values/strings.xml. However, if your minimum API level is 21 or higher, it is left in: If your minimum Android API level is 20 or lower, the code below is removed before building, since it's not a supported API on Android API level 20. This is done automatically by androiddeployqt and Qt Creator during packaging. Based on the minimum required Android API level of your application it might be necessary to remove some of this code. One thing to note about the files in this directory is that they can contain code specific to certain Android versions. At this point, the Java code in the templates is used to delegate events from Android into Qt. The code in here will load the required Qt libraries, based on the meta-information given in Manifest file.Īfter loading the libraries, the Java code will call into the application's native main() function on a new thread and the application will launch. 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). Note: The androiddeployqt Tool automates this process.
