1. First complete the project (any eng/user), then save the jar package to replace the JAVA code, in the Alps/out/target/common/obj/java_libraries/xxx__intermediates directory
Classes.jar
Javalib.jar
2. Please save the following files to Java_library_prebuilt.mk and place them under the Alps/build/core/directory:
Note: There are 11 places to start the TAB key (make syntax for the command to start the TAB key, but the site does not support the TAB key), save as a file after you open the edit, 11 (the following flag) to re-tab key processing again.

3. Add in Alps/build/core/config.mk:
Build_java_library_prebuilt:= $ (Build_system)/java_library_prebuilt.mk
4. Delete the corresponding Java code and the corresponding android.mk, then create a new android.mk in the current directory, and copy the 1th step back up the 2 files to android.mk (note that the file name can not be modified, otherwise unrecognized!!!), The new android.mk is written as follows:
Local_path: = $ (call My-dir)
Include $ (clear_vars)
Local_module: = Services
Local_module_path: = $ (target_out_java_libraries)
Include $ (build_java_library_prebuilt)
5. Re-complete the compilation project (any eng/user), download the View effect
6. Important note, because the 1th step save Classes.jar is not through proguard, outflow to easily be anti-compilation, please do Proguard, but please do not put the interface Proguard, or compile failed!
How Android uses jar packages instead of Java code compilation
