createOpenFrameworksLibArmeabi-v7aDebugArm7StaticLibrary'

I get the following error when i try to build
Error:Execution failed for task ‘:openFrameworksProject:createOpenFrameworksLibArmeabi-v7aDebugArm7StaticLibrary’.

Could not find Static library archiver ‘ar’. Searched in:
- /home/baskaran/Desktop/Updated_AndroidStudio/android-sdk-linux/ndk-bundle/android-ndk-r10e/toolchains/llvm-3.6/prebuilt/linux-x86_64/bin

Thanks in Advance
