• portable dalvik.vm.execution-mode=int:portable
• fast dalvik.vm.execution-mode=int:fast
• JIT dalvik.vm.execution-mode=int:jit

Not all platforms have an optimized implementation. In such cases, the “fast” interpreter is generated as a series of C stubs, and the result will be slower than the “portable” version

Default RO: ro.kernel.android.checkjni can be overriden by: dalvik.vm.checkjni

setprop dalvik.vm.checkjni true

To pass dalvik.vm.jniopts option as -Xjniopts argument.

setprop dalvik.vm.jniopts forcecopy

setprop dalvik.vm.extra-opts "-Xss16K"
