User clicks the application icon on mobile terminal desktop, that is, starts this and apply corresponding Activity, pass through
Activity can provide the interface to interact with the application to the user, and receive user's operation.
It is existing camera applications process flow referring to Fig. 1 by taking camera applications as an example：
Step 101, camera applications icon is clicked, the corresponding Activity of camera applications is started；
Step 102, Activity loads camera and corresponds to UI topology files；
Step 103, Activity starts camera Camera；
Step 104, Activity shows that UI is laid out corresponding preview interface；
Step 105, user can start video recording (running) by operating the button in preview interface；
Step 106, in video process, if receiving and dispatching short message or taking phone (starting short message application or phone application),
Activity closes camera；
Step 107, Activity destroys UI layouts；
Step 108, the corresponding Activity of camera applications is exited.
As it can be seen that the prior art is by Activity control camera video recordings and interface display, when Activity is exited, camera
It closes, can not continue to record a video.But in some feature application scenarios, for example, law enforcement field, needs uninterrupted sampling image (real
When record a video), and existing processing mode cannot be satisfied real-time recording demand.
In view of the above-mentioned problems, the present invention provides a kind of kinescope method based on android system, referring to Fig. 2, for the present invention
Implement a kind of flow chart of the kinescope method based on android system exemplified, which is described video process.
Step 201, when Activity is exited, unbundlings are with Activity bindings for controlling Camera video recordings
Service。
The present invention controls Camera using the Service components of android system.
When Activity starts, Activity and Service is bound, so that Activity is passed through Service and uses camera
Video recording；When exiting Activity, Activity and Service is unbinded, exiting for Activity is made not influence Service to phase
The control of machine.
Step 202, Camera described in the Service Background controls records a video.
Since Service components have running background characteristic, after by step 201 and Activity unbundlings,
Service can Background control Camera video recording, meet the real-time recording demand of mobile terminal.
Further, since Service classes do not have UI to show, also not generating UI with user interacts, in order to start in Activity
When show camera preview interface, Service utilizes the WindowManager (common class of Android) of android system
The corresponding UI layouts of Camera are loaded, so that the corresponding preview interface of UI layouts can be shown in Activity.As the Activity
When exiting, Service minimizes UI layouts (for example, setting UI sizes are 1 × 1 pixel using WindowManager again
Point) so that after current Activity is exited, do not influence the display of the Activity newly started.
It should be added that after being exited due to Activity, the Camera video recordings of Service Background controls are no longer aobvious
Show camera preview interface, therefore, mobile terminal can go out screen, and to reduce electric quantity consumption, extend mobile terminal uses duration.
Now with a specific embodiment, the video process based on android system is discussed in detail.
It is a kind of camera applications process flow shown in the embodiment of the present invention referring to Fig. 3 still by taking camera applications as an example：
Step 301, user clicks the camera applications icon for being installed on mobile terminal desktop, and it is corresponding to start camera applications
Activity；
Step 302, start Service, the i.e. CameraService for controlling camera (Camera) video recording, it should
CameraService can be controlled by Activity to be started, also can be by other startup events (for example, physical button, touch event
Deng) triggering, it controls CameraService and pre-actuates；
Step 303, in the onbind () of CameraService, Surface is completed by initSurface () and (is drawn
Cloth) establishment, pass through addView () complete View (camera corresponds to UI topology files) load；
Wherein, addView () realizes that user only needs will be designed using the WindowManager of android system
UI topology files (including each control information, for example, the position of button, picture, file, size, color etc.) are transmitted as parameter
To WindowManager.
Step 304, CameraService controls camera and starts；
Step 305, CameraService controls UI by showWindow () and shows；
Step 306, when Activity binds CameraService by bindCameraService (), UI corresponds to phase
Machine preview interface corresponds to screen display in foreground by Activity.It is a kind of camera shown in the embodiment of the present invention referring to Fig. 4
The schematic diagram of preview interface.
Step 307, due to the binding of step 306, CameraService control cameras (video recording) run on foreground；
Step 308, in video process, if taking phone, camera applications corresponding A ctivity unbundlings
CameraService；
Step 309, in the onUnbind () of CameraService, UI layouts are minimized by hideWindow (),
Minimize camera preview interface；
After camera preview interface minimizes, mobile terminal shows that phone application corresponds to interface.
Step 310, camera applications corresponding A ctivity is exited；
Step 311, CameraService Background controls camera continues to record a video；
Step 312, event (for example, again tapping on physical button) triggering is exited via service, CameraService is closed
Camera stops video recording；
Step 313, CameraService destroys UI layouts；
Step 314, CameraService is exited.
As it can be seen that the present invention is when Activity is exited, by unbinding CameraService, make CameraService can be with
Backstage continues to control camera video recording, to meet real-time recording demand.
Fig. 5 is a kind of hardware architecture diagram of mobile terminal provided by the invention.The terminal 5 includes processor 501, deposits
Contain machine readable storage medium 502, the camera Camera504 of machine-executable instruction.Wherein, processor 501 can with machine
Reading storage medium 502 can communicate via system bus 503.Also, by read and execute in machine readable storage medium 502 with
The corresponding machine-executable instruction of video recording logic based on android system, processor 501 can perform above-described be based on
The kinescope method of android system.
