// The dexpreopt package converts a global dexpreopt config and a module dexpreopt config into rules to perform
|
|
// dexpreopting and to strip the dex files from the APK or JAR.
|
|
//
|
|
// It is used in two places; in the dexpeopt_gen binary for modules defined in Make, and directly linked into Soong.
|
|
//
|
|
// For Make modules it is built into the dexpreopt_gen binary, which is executed as a Make rule using global config and
|
|
// module config specified in JSON files. The binary writes out two shell scripts, only updating them if they have
|
|
// changed. One script takes an APK or JAR as an input and produces a zip file containing any outputs of preopting,
|
|
// in the location they should be on the device. The Make build rules will unzip the zip file into $(PRODUCT_OUT) when
|
|
// installing the APK, which will install the preopt outputs into $(PRODUCT_OUT)/system or $(PRODUCT_OUT)/system_other
|
|
// as necessary. The zip file may be empty if preopting was disabled for any reason. The second script takes an APK or
|
|
// JAR as an input and strips the dex files in it as necessary.
|
|
//
|
|
// The intermediate shell scripts allow changes to this package or to the global config to regenerate the shell scripts
|
|
// but only require re-executing preopting if the script has changed.
|
|
//
|
|
// For Soong modules this package is linked directly into Soong and run from the java package. It generates the same
|
|
// commands as for make, using athe same global config JSON file used by make, but using a module config structure
|
|
// provided by Soong. The generated commands are then converted into Soong rule and written directly to the ninja file,
|
|
// with no extra shell scripts involved.
