Optimization: remove duplicated flags computations for getInstalledPackages Below are some test runs that show 100 iterations of getInstalledPackages ran at activity startup of touchlatency app to demonstrate the perf cost. R Baseline: https://screenshot.googleplex.com/PnVi5APraJo https://pprof.corp.google.com/?id=dc105ca9592f8367c381e2dcf7f1847d R Optimized: https://pprof.corp.google.com/?id=2d1d9fadc20bcc61d41bd52116bd94e3 https://screenshot.googleplex.com/OAwJnvwPqPH Savings: 8% of system_server binder response time when the call is executed. In terms total binder transaction time. Savings are 2% of the total binder call time.
