I'm trying to test some app on my Samsung Galaxy S2 (Android 4.1.2), but on the installation step of the build process I get this: Unknown option -d I don't get this error if I do the same but on a Galaxy Note 10.1 2014 (Android 4.4.2) Running the command manually without the -d works: ./adb install -r [path to the apk] I don't know if this helps, but here's some output from the building process: --- - Running process: /usr/sbin/system_profiler -detailLevel full SPHardwareDataType Using 2 compile threads Using specified NDK root "/opt/android-ndk" Found TOOLCHAIN_VERSION 4.4.3 Found ANDROID_HOST darwin-x86 Deduced android NDK 8 Using newest NDK platform: 14 ....... -build-setup: [getbuildtools] Using latest Build Tools: 19.1.0 [echo] Resolving Build Target for AutoNegro...
