Abstract
The present invention relates to smart machine technologies.The present invention is to solve do not have to detect the whether normal problem of USB device state in the Android system of existing Android intelligent equipment, provide a kind of method of Android intelligent equipment detection USB device, its technical solution can be summarized as: first when USB device accesses Android intelligent equipment, application program traversal/sys/bus/usb/device, find the USB device path newly accessed, judge whether there is newly added equipment path, if having and having ep_ee file in only one or newly-increased catalogue, the number of devices for then showing current USB port access has been more than supported number, otherwise driver catalogue has been checked whether, think that USB device access is normal if having, otherwise show that current USB device does not drive.The invention has the advantages that facilitating user, it is suitable for Android intelligent equipment.
Description
Technical field
The present invention relates to smart machine technologies, the in particular to technology of Android intelligent equipment detection USB device.
Background technique
Without the detection whether normal function of USB device state in the Android system of traditional Android intelligent equipment, and by
In the limitation of USB device state or smart machine terminal port USB equipment access number, will lead to part USB device can not normally make
With.
Summary of the invention
The invention aims to solve to be without detection USB device state in the Android system of current Android intelligent equipment
No normal problem provides a kind of method of Android intelligent equipment detection USB device.
The present invention solves its technical problem, the technical solution adopted is that, the method that Android intelligent equipment detects USB device,
Characterized by comprising the following steps:
Step 1, when USB device access or extract Android intelligent equipment when, the UsbHostManager of Android intelligent equipment
Sending device plug broadcast, and additional information is set for access or is extracted；
After step 2, background application receive equipment plug broadcast, delay certain time is handled, and is taken out wherein
Additional information, extraction is judged whether it is, if then deleting the institute of the USB device in access device hash table in application program
There is information, otherwise enters step 3；
Step 3, application program traversal/sys/bus/usb/device will be set in the catalogue and application program under the path
The device path of facility information compares in standby hash table, finds the USB device path newly accessed, and judge whether there is newly added equipment
Path, if having and newly added equipment path only one, enter step 4, enter if having newly added equipment path and more than one
Step 5；
Step 4, the number of devices for showing current USB port access have been more than supported number, and user is prompted to set the USB
It is standby to be linked into other USB ports；
Step 5 has checked whether ep_ee file into newly-increased catalogue, and 4 are entered step if having, otherwise enters step 6；
Step 6 has checked whether driver catalogue, thinks that USB device access is normal if having, otherwise shows current
USB device does not drive, and prompts user.
Specifically, the Android intelligent equipment is the smart television of Android system or the intelligent sliding of Android system in step 1
Dynamic terminal.
Further, the intelligent mobile terminal of the Android system is the smart phone of Android system or putting down for Android system
Plate computer.
Specifically, the certain time is 10 seconds in step 2.
Further, further comprising the steps of:
When all USB device informations are checked in step 7, user's selection, USB device letter is read from the hash table of application program
Breath shows each USB device information in the form of multistage catalogue.
The invention has the advantages that detecting the side of USB device by above-mentioned Android intelligent equipment in the present invention program
Method can provide the user with abnormal cause prompt when newly access USB device exception, so that user be guided to solve the problems, such as, increase
Strong user experience, facilitates user.
Specific embodiment
Below with reference to embodiment, the technical schemes of the invention are described in detail.
The method of Android intelligent equipment detection USB device of the present invention are as follows: first when USB device accesses or extracts Android
When smart machine, the UsbHostManager sending device of Android intelligent equipment plugs broadcast, and additional information is arranged as access
Or extract, after background application receives equipment plug broadcast, delay certain time is handled, and takes out additional letter therein
Breath, judges whether it is extraction, if then deleting all information of the USB device in access device hash table in application program,
Otherwise application program traversal/sys/bus/usb/device, will be in the catalogue and application program under the path in equipment hash table
The device path of facility information compares, and the USB device path newly accessed is found, and judge whether there is newly added equipment path, if having
And newly added equipment path only one, then show that the number of devices of current USB port access has been more than supported number, prompt to use
The USB device is linked into other USB ports by family, and entering to increase catalogue newly and check if having newly added equipment path and more than one is
It is no to have ep_ee file, show that the number of devices of current USB port access has been more than supported number if having, prompts user will
The USB device is linked into other USB ports, has otherwise checked whether driver catalogue, and USB device access is being thought if having just
Often, otherwise show that current USB device does not drive, prompt user.
Embodiment
The method of the Android intelligent equipment detection USB device of the embodiment of the present invention comprising following steps:
Step 1, when USB device access or extract Android intelligent equipment when, the UsbHostManager of Android intelligent equipment
Sending device plug broadcast, and additional information is set for access or is extracted.
In this step, Android intelligent equipment can be the smart television of Android system or the intelligent mobile terminal of Android system
Deng, and smart phone or the tablet computer of Android system of the intelligent mobile terminal of Android system such as Android system etc..
After step 2, background application receive equipment plug broadcast, delay certain time is handled, and is taken out wherein
Additional information, extraction is judged whether it is, if then deleting the institute of the USB device in access device hash table in application program
There is information, otherwise enters step 3.
In this step, certain time can be 10 seconds.Its object is to avoid booting when or USB abnormal electrical power supply and cause frequency
Inessential processing caused by numerous sending equipment plug broadcast.
Step 3, application program traversal/sys/bus/usb/device will be set in the catalogue and application program under the path
The device path of facility information compares in standby hash table, finds the USB device path newly accessed, and judge whether there is newly added equipment
Path, if having and newly added equipment path only one, enter step 4, enter if having newly added equipment path and more than one
Step 5.
Step 4, the number of devices for showing current USB port access have been more than supported number, and user is prompted to set the USB
It is standby to be linked into other USB ports.
Step 5 has checked whether ep_ee file into newly-increased catalogue, and 4 are entered step if having, otherwise enters step 6.
Step 6 has checked whether driver catalogue, thinks that USB device access is normal if having, otherwise shows current
