Aapt android download

On the host's command-line shell, run:. If you want to improve test execution time, you can shard the tests across multiple devices. Sharding requires the host to connect at least two devices, but six or more devices are recommended for efficiency. When sharding more than 1 device:. If you don't want to run the whole test suite, you can run the CTS plan of your choice from the command line:. For additional command options depending on CTS versions, refer to the console command reference , or under "help all" in the Tradefed console.

Run multiple Retry sessions until all test modules are completed and the test failure numbers are the same in the last two retry sessions. You can do this by adding extra properties to the ext block in the top-level build. To access these properties from a module in the same project, use the following syntax in the module's build. Note: Although Gradle allows you to define project-wide properties at the module level, you should avoid doing so because it causes the modules that share those properties to be coupled.

Module coupling makes it more difficult to later export a module as a stand-alone project and effectively prevents Gradle from utilizing parallel project execution to speed up multi-module builds.

The module-level build. This sample Android app module build. Gradle also includes two properties files, located in your root project directory, that you can use to specify settings for the Gradle build toolkit itself:. The most common issue with Windows long paths is that tools such as ld. In local. The path of that symlink can be shorter than the existing NDK folder. For example, ndk.

When you make changes to the build configuration files in your project, Android Studio requires that you sync your project files so that it can import your build configuration changes and run some checks to make sure your configuration won't create build errors. To sync your project files, click Sync Now in the notification bar that appears when you make a change, as shown in figure 3, or click Sync Project from the menu bar. If Android Studio notices any errors with your configuration, for example, your source code uses API features that are only available in an API level higher than your compileSdkVersion , the Messages window appears to describe the issue.

Figure 3. Syncing the project with build configuration files in Android Studio. Android Studio logically groups source code and resources for each module into source sets. Additional source set directories are optional, and Android Studio does not automatically create them for you when you configure new build variants.

For example, to generate the "fullDebug" version of your app, the build system merges code, settings, and resources from following source sets:. The source sets you can choose from are based on your build configurations, and Android Studio automatically creates the required directories if they don't already exist. If different source sets contain different versions of the same file, Gradle uses the following priority order when deciding which file to use source sets on the left override the files and settings of source sets to the right :.

This allows Gradle to use files that are specific to the build variant you are trying to build while reusing activities, application logic, and resources that are common to other versions of your app. When merging multiple manifests , Gradle uses the same priority order, so each build variant can define different components or permissions in the final manifest.

This is a required flag because you must specify a path to a directory where AAPT2 can output and store the compiled resources.

Although you can use this flag to compile multiple resource files with one command, it disables the benefits of incremental compilation and thus, should not be used for large projects. Use this option if you have already processed the PNG files, or if you are creating debug builds that do not require file size reduction.

Enabling this option results in a faster execution, but increases the output file size. This flag should be used for unexpected compile time errors. Additionally, other auxiliary files like R. That is, you can't deploy this APK to a device. If you're not using the Android Gradle Plugin to build your app from the command line , you can use other command line tools, such as d8 to compile Java bytecode into DEX bytecode and apksigner to sign your APK. AAPT2 links the result against android. This is a required flag because you must specify the path for the output APK that can hold the linked resources.

This is a required flag because the manifest file encloses essential information about your app like package name and application ID. You can use this directory to store original unprocessed files.

To learn more, read Accessing original files. When you a provide a resource file that overlays extends or modifies an existing file, the last conflicting resource given is used.

The package ID that you specify must be greater than or equal to 0x7f unless used in combination with --allow-reserved-package-id. Reserved package IDs are IDs that are normally assigned to shared libraries and are in the range from 0x02 to 0x7e inclusive. By using --allow-reserved-package-id , you can assign IDs that fall in the range of reserved package IDs. For example, if you have dependencies on the support library which contains translations for multiple languages , you can filter resources just for the given language configuration, like English or Spanish.

You must define the language configuration by a two-letter ISO language code, optionally followed by a two letter ISO alpha-2 region code preceded by lowercase 'r' for example, en-rUS. There are several pixel density qualifiers available to use in your app, such as ldpi, hdpi, and xhdpi. When you specify a preferred density, AAPT2 selects and stores the closest matching density in the resource table and removes all others. Suitable as input to the bundle tool for generating an Android App Bundle.

This option allows assigned IDs to remain stable even when you delete or add new resources while linking. It should be used in conjunction with --rename-manifest-package. For example, the following command prints content from the resource table of the specified APK:. You need to specify one of the following sub-commands with the dump command:. Although AAPT2 should immediately work with older projects, this section describes some behavior changes that you should be aware of.

In previous versions of AAPT, elements nested in incorrect nodes in the Android manifest were either ignored or resulted in a warning.

For example, consider the following sample:. However, with AAPT2, you get the following error:. To resolve the issue, make sure your manifest elements are nested correctly. For more information, read Manifest file structure. You can no longer indicate the type of a resource from the name attribute.

For example, the following sample incorrectly declares an attr resource item:. Fixed Java finding script to look for the currently supported version of Java 1. Enable this mode by adding the following line to the project. Updated the build to generate R resource classes for library projects with only the IDs needed by the libraries, reducing the risk of hitting DEX file limits for fields and methods.

Improved the build so that several editing features code completion, resource chooser, go to declaration properly handle library project resources. Lint Added over 25 new lint rules for resources, locale settings, layout files, incorrect use of SparseArray and PowerManager.

WakeLock and manifest issues. Updated reporting to include errors in library projects if the library project is in the list of projects to be checked. Added a new lint target to the Ant build system for easier integration with continuous build systems. Added new --sources and --classpath arguments to point to sources with different directory structures. Added support for class file flow analysis. Improved emulators so that they launch with a skin that is dynamically generated and reflects the actual hardware configured in the AVD Manager.

Bug fixes: Fixed manifest merger to properly adapt library classes in the merged manifest. Bug fixes: Fixed wrong check on build state that forced repetitive Java code recompilation. Fixed problems with running more than one emulator and running multiple emulators with GPU acceleration.

Improved resize algorithm for better rendering on scaled emulator windows. Fixed a bug in the lint check for unprotected broadcast receivers to ignore unprotected receivers for default Android actions. Fixed build issue for projects using Renderscript. Fixed memory leak in the emulator. General notes: Added new Device Monitor application, grouping Android debugging tools into a single application, including ddms, traceview, hierarchyviewer and Tracer for GLES. Build System Added automatic merging of library project manifest files into the including project's manifest.

Enable this feature with the manifestmerger. Added automatic ProGuard support for the aapt -G flag. This change causes the build system to generate a temporary ProGuard keep-rules file containing classes that are referenced from XML files such as custom views and pass this to ProGuard at shrink time.

This can make the resulting APK much smaller when using just a small portion of a large library project such as the Android Support library , since the catch-all rules to keep all custom views from the default ProGuard configuration file have also been removed.

Added two ProGuard configuration files for use in projects: proguard-android-optimize. SDK Manager Improved caching to reduce downloading of repository definitions. Bug fixes: Build Fixed problem where test projects did not have access to the full classpath of tested projects, including Library Projects and third-party jars. Fixed deployment logic so that applications with embedded tests can now be deployed and tested like test applications, including code coverage information.

Fixed Ant support for testing projects with libraries. Bug fixes: Fixed an issue that prevented some developers from running the emulator with GPU acceleration.

General notes: Updated the SdkController app to encapsulate both sensor and multitouch emulation functionality. General notes: Emulator Added support for hardware accelerated graphics rendering. Added experimental support for multi-touch input by enabing the emulator to receive touch input from a USB-tethered physical Android device.

In addition to many new features, this update fixes the Conversion to Dalvik format failed with error 1 error some users have experienced. Updated the default proguard. Split the ProGuard configuration file has been in half, with project specific flags kept in project and the generic Android flags distributed and updated with the tools themselves. Build Added a feature that allows you to run some code only in debug mode. You can check the BuildConfig.

DEBUG constant in your code to run debug-only functions.
