What’s the use of LLVM in Android NDK Toolchains? A little recap: I was building my native project with Gradlew on Ubuntu, targeting arm and x86_64 architectures. Seems that LLVM were utilized to call C/C++ compiler of arm-linux-androideabi-4.9 as well as x86_64(?)

Detecting number of CPU cores on Android from native code
I’m using sysconf( _SC_NPROCESSORS_ONLN ) (which, I believe, is the recommended way) to get the number of CPU cores. It works fine or Mac and Linux, but on my 4-core Android tablet it returns 2. How can I get the actual number of cores on Android from native code (without using JNI to call Java Android API)? Answer Neither sysconf(
