JNI principle: [analysis of registration process of Dalvik virtual machine JNI method] Example: when libnanosleep When the so file is loaded, the function JNI_OnLoad will be called. In function JNI_ In onload, the parameter vm describes the Dalvik virtual machine in the current thread. A JNIEnv object can be obtained by calling its member fun ...
