Introduce a set of optional Java optimization settings for SystemUI, based on the Soong variable added in aosp/1896612. Opting in to optimizations can be achieved with either: * Env: export SYSTEM_OPTIMIZE_JAVA=true * Make: $(call add_soong_config_var_value,ANDROID,SYSTEM_OPTIMIZE_JAVA,true) As these optimizations can change the resulting stack traces, a parallel effort is working to simplify retracing of stack traces for more accurate debugging and diagnostics. Additional stabilization and testing will occur before any effort to enable these optimizations by default for specific targets. Also note that there are no plans to enable obfuscation. Preliminary results (w/ `SYSTEM_OPTIMIZE_JAVA=true`): * SystemUI.apk (31MB -> 26MB) Bug: 203472868 Test: SYSTEM_OPTIMIZE_JAVA=true m (validate SystemUI.apk) Change-Id: Idd8d5ef32c06e992ad35846eb5fab67ecb58830a
