| # Usage: dex-preopt [options] path/to/input.jar path/to/output.odex |
| # |
| # This tool runs a host build of dalvikvm in order to preoptimize dex |
| # files that will be run on a device. |
| # |
| # The input may be any sort of jar file (including .apk files), as long |
| # as it contains a classes.dex file. Note that optimized versions of |
| # bootstrap classes must be created before this can be run on other files; |
| # use the "--bootstrap" option to do this. |
| # |
| # The "output.dex" file must not already exist. |
| # |
| # This is expected to be running in a user build environment, where |
| # "dexopt" is available on the host. |
| # |
| # Options: |
| # --bootstrap -- Process the bootstrap classes. |
| # --build-dir=path/to/out -- Specify where the base of the build tree is. |
| # This is typically a directory named "out". If not specified, it is |
| # assumed to be the current directory. The specified input and output |
| # paths are taken to be relative to this directory. |
| # --product=name -- Specify the name of the product to work on. There |
| # should be a directory with this name under build-dir/product. If |
| # not specified, then there must only be one such directory, and that |
| # one will be used. |
| # --boot-jars=list:of:jar:base:names -- Specify the list of base names |
| # of bootstrap classpath elements, colon-separated. Order is significant |
| # and must match the BOOTCLASSPATH that is eventually specified at |
| # runtime on the device. This defaults to "core". However, this really |
| # needs to match the target product's BOOTCLASSPATH, which, as of this |
| # writing, doesn't have a super-strict way of being defined within the |
| # build. You can find variations of it in different init.rc files under |
| # system/core/rootdir or under product-specific directories. |
| # --verify={none,remote,all} -- Specify what level of verification to |
| # do. Defaults to "all". |
| # --optimize={none,verified,all} -- Specify which classes to optimize. |
| # Defaults to "verified". |
| # --no-register-maps -- Indicate that the output should not contain |
| # register maps. By default, register maps are created and included. |
| # |
| |
| # Defaults. |
