I need to do somethings that must be done from the command prompt of the android tool.
but every one says it’s in the platform tools folder in the sdk path but which file is it?
that might help:
the contents of platform tools folder:
aapt.exe
adb.exe
aidl.exe
dexdump.exe
dx.bat
fastboot.exe
llvm-rs-cc.exe
source.properties
AdbWinApi.dll
AdbWinUsbApi.dll
