Android Gradle Plugin 3.0.0 and higher enable AAPT2 by default, and you typicallywon't need to invoke aapt2 yourself. However, if you prefer to use yourterminal and your own build system over Android Studio, you can use AAPT2 fromthe command line. You can also debug build errors related to AAPT2 from the command line.To do so, you can find AAPT2 as a standalone tool in Android SDK Build Tools 26.0.2 and higher.
Once you have downloaded the SDK Build Tools, you can find AAPT2 located inandroid_sdk/build-tools/version/.Because a newer revision of the Android SDK Build Tools is not released veryoften, the version of AAPT2 included in your SDK Build Tools might not be thelatest. To get the latest version of AAPT2, read Download AAPT2 from Google Maven.

To use AAPT2 from the command line on Linux or Mac, run the aapt2 command.On Windows, run the aapt2.exe command. AAPT2 supports faster compilation ofresources by enabling incremental compilation. This is accomplished by breakingresource processing into two steps:
AAPT2 supports compilation of all Android resource types,such as drawables and XML files. When you invoke AAPT2 for compilation, youshould pass a single resource file as an input per invocation. AAPT2 then parsesthe file and generates an intermediate binary file with a .flat extension.
The files AAPT2 outputs are not executables and you must later include thesebinary files as input in the link phase to generate an APK. However, thegenerated APK file is not an executable that you can deploy on an Androiddevice right away, as it does not contain DEX files (compiled bytecode) and isnot signed.
As shown in the table above, the name of the output file depends on the inputfile name and the name of its parent directory (the resource type andconfiguration). For the example above with strings.xml as input, aapt2automatically names the output file as values-en_strings.arsc.flat.On the other hand, the file name for the compiled drawable file stored inthe drawable directory will be drawable_img.png.flat.
In the link phase, AAPT2 merges all the intermediate files generated from thecompilation phase such as resource tables, binary XML files, and processed PNGfiles and packages them into a single APK. Additionally, other auxiliary fileslike R.java and ProGuard rules files can be generated during this phase.However, the generated APK does not contain DEX bytecode and is unsigned.That is, you can't deploy this APK to a device. If you're not using the AndroidGradle Plugin to build your app from the command line,you can use other command line tools, such as d8 tocompile Java bytecode into DEX bytecode and apksignerto sign your APK.
In the following example, AAPT2 merges the two intermediate files -drawable_Image.flat and values_values.arsc.flat, and the AndroidManifest.xmlfile. AAPT2 links the result against android.jar file which holds theresources defined in the android package:
Prior to AAPT2, AAPT was the default version of Android Asset Packaging Tooland it has now been deprecated. Although AAPT2 should immediately work witholder projects, this section describes some behavior changes that you should beaware of.
ForegroundLinearLayout includes threeattributes:foregroundInsidePadding,android:foreground, andandroid:foregroundGravity.Note that foregroundInsidePadding is not included in the android namespace,unlike the other two attributes.
In previous versions of AAPT, the compiler would silently ignoreforegroundInsidePadding attributes when you define it with the androidnamespace. When using AAPT2, the compiler catches this early and throws thefollowing build error:
If your app has a dependency on a third party library that was built using olderversions of the Android SDK Build Tools, yourapp might crash at runtime without displaying any errors or warnings. This crashmight occur because, during the library's creation, the R.java fields aredeclared final and, as a result, all of the resource IDs are inlined in thelibrary's classes.
AAPT2 relies on being able to re-assign IDs to library resources when buildingyour app. If the library assumes the IDs to be final and has them inlined inthe library dex, there will be a runtime mismatch. 152ee80cbc
