From 36c35119526023c9e28ec22915b26b1bf7da6bc3 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Tue, 25 Oct 2016 14:17:26 -0700 Subject: applypatch: Add testcases for applypatch executable. Refactor applypatch/main.cpp into libapplypatch_modes so that we can add testcases. Some changes to applypatch/main.cpp: - Replace char** argv with const char**; - Use android::base::Split() to split ":"; - Use android::base::ParseUInt(). Bug: 32383590 Test: Unit tests pass, install-recovery.sh works.
