aapt v[ersion]
   Print program version.


The Android Asset Packaging Tool (aapt) takes your application resource files, such as the AndroidManifest.xml file and the XML files for your Activities, and compiles them. An R.java is also produced so you can reference your resources from your Java code.


A summary of options is included below.
print Android-specific data (resources, manifest) when listing
specify which configurations to include. The default is all configurations. The value of the parameter should be a comma separated list of configuration values. Locales should be specified as either a language or language-region pair. Some examples:

If you put the special locale, zz_ZZ on the list, it will perform pseudolocalization on the default locale, modifying all of the strings so you can look for strings that missed the internationalization process. For example:

one or more device assets to include, separated by commas
force overwrite of existing files
specify a pixel tolerance to force images to grayscale, default 0
specify a jar or zip file containing classes to include
junk path of file(s) added
make package directories under location specified by -J
update existing packages (add new, replace older, remove deleted files)
verbose output
create extending (non-application) resource IDs
require localization of resource attributes marked with localization="suggested"
additional directory in which to find raw asset files
A file to output proguard options into.
specify the apk file to output
add an existing package to base include set
specify where to output R.java resource constant definitions
specify full path to AndroidManifest.xml to include in zip
specify where to output public resource definitions
directory in which to find resources. Multiple directories will be scanned and the first match found (left to right) will take precedence.
specifies an additional extension for which such files will not be stored compressed in the .apk. An empty string means to not compress any files at all.
inserts android:debuggable="true" in to the application node of the manifest, making the application debuggable even on production devices.
inserts android:minSdkVersion in to manifest. If the version is 7 or higher, the default encoding for resources will be in UTF-8.
inserts android:targetSdkVersion in to manifest.
ignores versioned resource directories above the given value.
when used with "dump resources" also includes resource values.
inserts android:versionCode in to manifest.
inserts android:versionName in to manifest.
generates R.java into a different package.
generate R.java for libraries. Separate libraries with ':'.
generate dependency files in the same directories for R.java and resource package
Automatically add resources that are only in overlays.
Like the -c option for filtering out unneeded configurations, but only expresses a preference. If there is no resource available with the preferred configuration then it will not be stripped.
Rewrite the manifest so that its package name is the package name given here. Relative class names (for example .Foo) will be changed to absolute names with the old package so that the code does not need to change.
Rewrite the manifest so that all of its instrumentation components target the given package. Useful when used in conjunction with --rename-manifest-package to fix tests against a package that has been renamed.
Specifies which variant to choose for strings that have product variants
changes default encoding for resources to UTF-16. Only useful when API level is set to 7 or higher where the default encoding is UTF-8.
Make the resources ID non constant. This is required to make an R java class that does not contain the final value but is used to make reusable compiled libraries that need to access resources.
Forces aapt to return an error if it fails to insert values into the manifest with --debug-mode, --min-sdk-version, --target-sdk-version --version-code and --version-name. Insertion typically fails if the manifest already defines the attribute.
Generates a text file containing the resource symbols of the R class in the specified folder.
Assets to be ignored.
