You implement this API according to the delivery type of Integrate with Play Asset Delivery Library (Optional) Configure your app bundle to support different texture Gradle generates the manifest for each asset pack and outputs the assets/ asset-pack-name/assets/ your-asset-directories:ĭirectory that contains all assets delivered as part of the asset pack.asset-pack-name/manifest/AndroidManifest.xml:Ĭonfigures the asset pack’s identifier and delivery mode.In the generated app bundle, the root-level directory now includes the asset-pack-name/src/main/assets/ your-asset-directoriesīuild the Android App Bundle with Gradle.The directory structure for your app should Place assets in the src/main/assets directory. In the asset pack directory, create the following subdirectory: In the project’s adle file, include all asset packs in your In the project’s app adle file, add the name of every asset packĪssetPacks = PackName = " asset-pack-name" // Directory name for the asset packĭeliveryType = "" Make sure to specify the name of the asset pack and only one In the asset pack directory, create a adle file and add theįollowing code. Must start with a letter and can only contain letters, numbers, and This directory name is used as the asset pack name. In the top-level directory of your project, create a directory for the asset Update the version of the Android Gradle plugin in your project’s Using Play Asset Delivery in native games Codelab. You don't need to use Android Studio to perform these steps. Use the following steps to build Play Asset Delivery into your project’s AndroidĪpp Bundle. Then load the module corresponding to SO Library in Java.Use the steps in this guide to access your app’s asset packs from your C and C++ (Android Studio now supports direct compilation of SO libraries, but there are many pits where I choose to compile manually.) Locate the directory of the Android.mk file on the command line and run the ndk-build command of the NDK tool to compile the SO library we need.Ĭopy the SO library to the jniLibs directory of the Android Studio project Here we recommend an open source Gauss blur project. (There are many detailed JNI tutorials on the Web, not to mention here.) However, if you use ClassLoader to load SD card plug-in APK, and plug-in APK contains SO libraries, which involves loading SO libraries in plug-in APK, so we also need to know how to load SO libraries in SD card.įor example, if you use Java code to calculate every pixel of image Bitmap, the overall time-consuming will be very large, so you can consider using JNI. Unlike what we often say about dynamic loading based on lassLoader, SO libraries are loaded using System classes (so support for SO libraries is also the basic function of Android), so this is a supplementary explanation. so library can also be used in the field of security. so library is compiled by C++ and can only be decompiled into assembly code, it is more difficult to crack than Smali, so the. so libraries dynamically to accomplish some performance-demanding tasks (such as T9 search, or Bitmap decoding, image Gauss blurring, etc.). The latter is usually compiled from C/C++ code using NDK tools, running in the Native layer, which is much more efficient than Java code executing in the virtual machine. so library at APP runtime and invoking its encapsulated method through JNI. In fact, the use of JNI in Android includes dynamic loading, dynamic loading of the.
