Hi All, Am new to andriod and i started exploring on Andriod NDK. I Installed "android-ndk-1.6_r1" and Cygwin . I got host setup complete message but still am not able to generate the .so files using Cygwin. Am getting the following error: =================================== bash-3.2$ make APP=hello-jni make: /bin/sh: Command not found make: /bin/sh: Command not found make: /bin/sh: Command not found Android NDK: Building for application 'hello-jni' build/core/setup-toolchain.mk:20: *** Android NDK: Assertion failure: TARGET_PL ATFORM is not defined . Stop. ================================== Any Envrionment varibles need to set for this error ? Can any one help me to to run my native files. If possible provide me the simple steps to achive this. Thx in Advance..
