how to start or execute an EXECUTABLE app from Java apk or ndk

Question

I can't modify init.rc or init.target.rc, so I want to start or execute an EXECUTABLE app(under like system/bin/) from Java apk or ndk. So how to do it? Is there any API available?

Answer 1

Runtime.exec() is a common way to start child process from java. In native code you may use system() or combination of fork() and exec().
