Hi, Simo.
My NDK version is 15, and APP_PLATFORM has a default value of 14, which is compiled successfully. My android device system version is android 5.1.1, copy minitouch to /data/local/tmp directory; then execute the command "adb shell /data/local/tmp/minitouch", minitouch failed to start successfully, the following is the exception log.

WARNING: linker: /data/local/tmp/minitouch: unused DT entry: type 0x6ffffffe arg 0xa88
