2. The method of claim 1, wherein in the first step, the custom function key is a hardware key included in a non-standard keyboard, including an mute key, a handsfree key, or a redial key.
3. The method of claim 1, wherein the attributes in step 204 include a bus type of the virtual keyboard, a manufacturer ID of the virtual keyboard, a custom virtual keyboard ID, and a virtual keyboard name.
4. The method of claim 1, wherein in the step six, the key EVENT processing module receives the key EVENT C or D, encapsulates the scan code, the key press state and the key long press state into a newly created Android broadcast message E, carries a com.fv.aex.device.action.key_event broadcast action, and distributes the message E to application software monitoring the action in a form of Android broadcast.
5. The method of claim 4, wherein the application software is software that registers com.fv.aex.device.action.key_event action listeners with an Android system; After receiving the message E containing the above actions, the Android system calls onReceive (Context: context? Intent? triggering a hardware key or a key corresponding to the virtual keyboard according to the key event type, thereby triggering a corresponding function; keyCode is the value of the scan code.

Description

Method for remotely operating Android terminal hardware function keys based on virtual keyboard equipment Technical Field The invention belongs to the field of automatic testing, and particularly relates to a method for remotely operating Android terminal hardware function keys based on virtual keyboard equipment. Background With the continuous progress of network terminal technology, the functions of the network terminal are becoming diversified. In order to simplify the user operation in case of complicated product functions, manufacturers often add hardware keys for quick triggering functions on the network terminal device. The traditional terminal test flow is usually highly dependent on manual operation, so that a large amount of time and manpower resources are consumed, the terminal test flow is easily influenced by personal differences of operators, fatigue and other human factors, and the accuracy and reliability of test results are difficult to fully guarantee. Therefore, in order to effectively reduce the uncertainty introduced by manual key operation and remarkably improve the overall test efficiency, a set of method capable of automatically simulating the hardware key action is urgently required to be introduced so as to realize the automation and standardization of the test flow. The hardware keys of the terminal are generally mapped into one or several device nodes in the Android system. Therefore, a virtual keyboard device similar to the hardware keys is created in the system, and a custom key mapping table file is compiled, so that hardware function keys beyond the conventional keyboard can be flexibly simulated.
