Background technique

With the development of science and technology, the development of set-top boxes is becoming more and more rapid. In the customization of the set-top box based on the Android system, for the client in the set-top box, for example, APK (Android Package, Android installation package) has the requirement of monitoring system keys. Such as HOME (start) button, SET (setting) button and so on. When the client in the set-top box learns that the user presses these system keys, it needs to do some special processing to meet the corresponding services. This requires the system to provide a method that enables the client to monitor the system keys. As we all know, the system keys are usually directly processed by the processor of the set-top box, that is, the processor in the set-top box receives the system key information and performs corresponding processing according to the system key information. And after processing, the system key information is consumed. In this way, it is almost impossible for the client in the set-top box to obtain the information of these system keys.

For the above problems, no effective solution has been proposed yet.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a key monitoring method, which is applied to a set-top box, and the set-top box includes a processor and a client. As shown in Figure 1, the method includes:

Step 101, the processor monitors whether the system key information is received.

Specifically, when the user needs to send a system command to the set-top box, the user can send it through a button in the remote control device. At this time, the user may press a key on the remote control device, so that the remote control device sends system key information to the set-top box. The processor in the set-top box can monitor in real time whether the remote control device has sent the system key information, and then can monitor whether the system key information has been received.

Further, when the operating system of the processor in the set-top box is the Android (Android) system, the specific process of whether the set-top box processor monitors and receives the system key information is: the reading of the system key information of the Android system set-top box is based on linuxinput (input ) subsystem design. When the set-top box is turned on, WindowManagerService (window management service) is a Service (service) started in the Systemserver (system service) process, and is started by the set-top box processor. When WindowManagerService is initialized, it will initialize the button queue, and finally create a thread to read the linuxinputevent event. After the message queue is established, the processor of the set-top box will mainly intercept the system key information in the program frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java. The main two interception functions are, interceptKeyBeforeDispatching and interceptKeyBeforeQueueing. That is to say, after the message queue is established, the processor of the set-top box mainly uses the program frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java to intercept the system key information. The two interception functions used by the STB processor are, interceptKeyBeforeDispatching and interceptKeyBeforeQueueing.

Exemplarily, it is assumed that the user sends HOME button information through the remote control device. At this time, the processor of the set-top box can monitor the HOME button information sent by the remote control device.

Step 102, when detecting that the system key information is received, the processor broadcasts the system key information.

Specifically, when the processor of the set-top box detects that system key information is received, it can broadcast the system key information while performing data processing according to the system key information, so that other clients can monitor the system key information. Key information. Instead of consuming the system key information as in the prior art.

Further, when the system key information is detected and received, the processor broadcasting the system key information includes: when the system key information is detected and received, the processor generates an Intent (intention) message according to the system key information, and broadcasts the Intent message .

Specifically, when the processor of the set-top box detects that the system key information is pressed, it can monitor and receive the system key information. At this time, the processor of the set-top box can add the monitored system key information to the Intent message, and Broadcast this Intent message.

Further, since the processor of the set-top box in the prior art cannot broadcast the monitored system key information, therefore, in the present invention, it is necessary to intercept the program frameworks/base/policy/src/com/android of the system key information /internal/policy/impl/PhoneWindowManager.java is modified appropriately so that the processor can broadcast the monitored system key information. Since the processing information of the system key information by the processor is recorded in the interception function interceptKeyBeforeDispatching, the processor can broadcast the system key information by adding the processing information of the system key information monitored by broadcasting in the interceptKeyBeforeDispatching function.

The specific implementation code is as follows:

publiclonginterceptKeyBeforeDispatching(WindowStatewin,KeyEventevent,intpolicyFlags){

//…………

if(keyCode==KeyEvent.KEYCODE_HOME){

//Add the following code (the code for broadcasting system button information):

IntentkeyIntent = newIntent("com.test.key");

keyIntent.putExtra("whichkey",KeyEvent.KEYCODE_HOME);

this. sendBroadcast(keyIntent);

}

//…………

}

In this way, by modifying the above-mentioned interception function, after the processor monitors the system key information, it can use the above-mentioned modified interception function interceptKeyBeforeDispatching to broadcast the monitored system key information in the form of an Intent message.

As described in the above example, after the processor of the set-top box monitors the HOME button information, it can add the HOME button information to the Intent message, and broadcast the Intent message.

Step 103, the client monitors whether the processor broadcasts system key information.

Specifically, the client of the set-top box can monitor in real time whether the processor of the set-top box broadcasts system key information. In this way, when the processor of the set-top box broadcasts system key information, the client can monitor it in time.

Further, the specific implementation code of whether the client monitoring processor of the set-top box broadcasts the system key information is:

As mentioned in the above example, the client of the set-top box needs to monitor whether the processor of the set-top box broadcasts system key information in real time. Since, in this example, the processor of the set-top box broadcasts the Intent information including the HOME button information, at this time, the client of the set-top box can listen to the broadcast of the Intent information including the HOME button information by the processor of the set-top box.

Further, the client is an application program of the set-top box. For example, the client is APK.

Step 104, when listening to the processor broadcasting system key information, the client performs corresponding data processing according to the system key information.

Specifically, after the client of the set-top box listens to the system button information broadcast by the processor of the set-top box, it can determine the corresponding processing information according to the system button information, and then can perform corresponding data processing according to the processing information corresponding to the system button information. deal with.

It should be noted that, in the embodiment of the present invention, the processing information corresponding to the system key information in the client of the set-top box is preset by the user according to actual needs. For example, the processing information corresponding to the HOME button information is to display the exercise amount information of user a. The present invention is not limited thereto.

As described in the above example, after the client of the set-top box listens to the Intent message broadcast by the processor of the set-top box and includes the HOME button information, it can parse the Intent message and obtain the HOME button information contained therein. The client of the set-top box can determine its corresponding processing information according to the HOME button information, and then perform corresponding data processing according to the processing information corresponding to the HOME button information.
