What are the meaning of the aaptOptions.noCompress, etc.; can anybody explain them to me?
android { aaptOptions { noCompress 'foo', 'bar' ignoreAssetsPattern '!.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~' } } This affects all tasks using aapt.
Yes, docs give no clue.
Well aapt tool is inside specific build-tools folder and it has options as listed below.
For example ignoreAssetsPattern in build.gradle is related to --ignore-assets option
The next step would be looking at android gradle plugin to see how aapt is called.
There is also useNewCruncher false that can be used to surpass Issue 135757: New PNG cruncher doesn't support spaces in the path (UPDATE: it's fixed and should be handled automatically for you)
E:\Android\sdk-Android-Studio\build-tools\19.1.0>aapt -h ERROR: Unknown command '-h' Android Asset Packaging Tool Usage: aapt l[ist] [-v] [-a] file.{zip,jar,apk} List contents of Zip-compatible archive. aapt d[ump] [--values] WHAT file.{apk} [asset [asset ...]] strings Print the contents of the resource table string pool in the APK. badging Print the label and icon for the app declared in APK. permissions Print the permissions from the APK. resources Print the resource table from the APK. configurations Print the configurations in the APK. xmltree Print the compiled xmls in the given assets. xmlstrings Print the strings of the given compiled xml assets. aapt p[ackage] [-d][-f][-m][-u][-v][-x][-z][-M AndroidManifest.xml] \ [-0 extension [-0 extension ...]] [-g tolerance] [-j jarfile] \ [--debug-mode] [--min-sdk-version VAL] [--target-sdk-version VAL] \ [--app-version VAL] [--app-version-name TEXT] [--custom-package VAL] \ [--rename-manifest-package PACKAGE] \ [--rename-instrumentation-target-package PACKAGE] \ [--utf16] [--auto-add-overlay] \ [--max-res-version VAL] \ [-I base-package [-I base-package ...]] \ [-A asset-source-dir] [-G class-list-file] [-P public-definitions-file] \ [-S resource-sources [-S resource-sources ...]] \ [-F apk-file] [-J R-file-dir] \ [--product product1,product2,...] \ [-c CONFIGS] [--preferred-configurations CONFIGS] \ [raw-files-dir [raw-files-dir] ...] \ [--output-text-symbols DIR] Package the android resources. It will read assets and resources that are supplied with the -M -A -S or raw-files-dir arguments. The -J -P -F and -R options control which files are output. aapt r[emove] [-v] file.{zip,jar,apk} file1 [file2 ...] Delete specified files from Zip-compatible archive. aapt a[dd] [-v] file.{zip,jar,apk} file1 [file2 ...] Add specified files to Zip-compatible archive. aapt c[runch] [-v] -S resource-sources ... -C output-folder ... Do PNG preprocessing on one or several resource folders and store the results in the output folder. aapt s[ingleCrunch] [-v] -i input-file -o outputfile Do PNG preprocessing on a single file. aapt v[ersion] Print program version. Modifiers: -a print Android-specific data (resources, manifest) when listing -c 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: en port,en port,land,en_US 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: port,land,zz_ZZ -d one or more device assets to include, separated by commas -f force overwrite of existing files -g specify a pixel tolerance to force images to grayscale, default 0 -j specify a jar or zip file containing classes to include -k junk path of file(s) added -m make package directories under location specified by -J -u update existing packages (add new, replace older, remove deleted files) -v verbose output -x create extending (non-application) resource IDs -z require localization of resource attributes marked with localization="suggested" -A additional directory in which to find raw asset files -G A file to output proguard options into. -F specify the apk file to output -I add an existing package to base include set -J specify where to output R.java resource constant definitions -M specify full path to AndroidManifest.xml to include in zip -P specify where to output public resource definitions -S directory in which to find resources. Multiple directories will be scanned and the first match found (left to right) will take precedence. -0 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. --debug-mode inserts android:debuggable="true" in to the application node of the manifest, making the application debuggable even on production devices. --min-sdk-version inserts android:minSdkVersion in to manifest. If the version is 7 or higher, the default encoding for resources will be in UTF-8. --target-sdk-version inserts android:targetSdkVersion in to manifest. --max-res-version ignores versioned resource directories above the given value. --values when used with "dump resources" also includes resource values. --version-code inserts android:versionCode in to manifest. --version-name inserts android:versionName in to manifest. --custom-package generates R.java into a different package. --extra-packages generate R.java for libraries. Separate libraries with ':'. --generate-dependencies generate dependency files in the same directories for R.java and resource package --auto-add-overlay Automatically add resources that are only in overlays. --preferred-configurations 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. --rename-manifest-package 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. --rename-instrumentation-target-package 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. --product Specifies which variant to choose for strings that have product variants --utf16 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. --non-constant-id 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. --error-on-failed-insert 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. --output-text-symbols Generates a text file containing the resource symbols of the R class in the specified folder. --ignore-assets Assets to be ignored. Default pattern is: !.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~
