Intent, also known as intent, is a run-time binding mechanism that links two different components (activity, Service, Broadcastreceiver) in the process of running a program.

The communication between these components is mainly d

In fact, the difference between JNI and ndk can be understood as follows: JNI is a set of Sun APIs, while ndk is more like a tool, which is provided by Google itself and compiled by C/C ++. I.
