Java in Android based on Java Virtual machine, operating efficiency is relatively low, recently in the efficient large number multiplication, found that JNI or NDK can implement C and Java mixed, and reference C dynamic Library, and the C language in Android does not need to rely on the Java virtual machine, The efficiency is still very high.First, the constructi
