From: Xavier Ducrohet Date: Tue, 11 Sep 2012 21:45:22 +0000 (-0700) Subject: Add --output-text-symbols option to aapt. X-Git-Url: https://git.saurik.com/android/aapt.git/commitdiff_plain/232580c6c07e335d756a8c23e80d705fff3b8804?ds=sidebyside Add --output-text-symbols option to aapt. Library projects in the SDK are built using --non-constant-id to generate a temporary R.java class. When the library is packaged with the application to generate an apk, the R class is recreated with the proper IDs due to all the resources coming from the app and all the libraries. However for large apps with many libraries (each with their own R class in their package), this means a lot of unnecessary IDs: all R classes contains all the IDs including for resources from by projects they don't have access through the dependency graph. For really large apps (X,000 resources), with lots of libraries (10+), this can generate tens of thousands of resources, which can trigger dalvik's limit of 65K fields and methods per dex files. This changes lets aapt generate not only the R class but a simple text file containing the list of all those IDs so that it is easier to parse back. The SDK build system will not ask aapt to generate the R class of the libraries (through the --extra-packages option), instead it will then read this file to know what IDs are needed for each library and generate a much smaller R class for each library (using the same text file output from compiling all the resources to get the final integer value).
