TABLE 2

TABLE 3

From the information recorded by three media files of video, music and picture, the information recorded by the media database has many common information, such as: ID. The PC terminal can find the media files in the mobile terminal by acquiring the general information, such as the title, the folder name, the address of the files and the like. However, it is irrelevant whether the media files stored in the mobile terminal need to be uploaded with general information of the database. Therefore, the native media database needs to be upgraded.

Based on this, the embodiment of the invention adds a database column for recording whether the file is to be uploaded or not in the media database of the mobile terminal; correspondingly, the setting of the to-be-uploaded mark for the determined file to be uploaded is to update the content information corresponding to the database column.

As shown in table 4, the "is _ upload" column indicates whether the file is to be uploaded, the updating of the content information of the database column is equivalent to setting a to-be-uploaded flag for the file to be uploaded, and a setting such as setting to 1 may be used to indicate that the file is to be uploaded; otherwise, setting to 0 indicates that the file is not to be uploaded. Table 4 lists only the main content information common to tables 1, 2, and 3 to illustrate the change of the media database record; all original database column names and corresponding content information in the tables 1, 2 and 3 exist and are kept unchanged; in other words, the "is _ upload" column and the corresponding content information are added to the original contents in table 1, table 2, and table 3, respectively.

TABLE 4

In practical application, the "is _ upload" column in table 4 is added to tables 1 to 3 respectively, and corresponds to the recording of three types of media files, i.e. tables 1 to 3 are still true in the mobile terminal, and only updated tables 1 to 3 with the "is _ upload" column are added; specifically, each database table is located under mobile terminal/data/data/com. And adding a column with a database column name of 'is _ upload' to each database table of the media database by modifying the Android frame layer code, wherein content information corresponding to the column indicates whether the file is to be uploaded or not, and modifying the content information of the column is to set a to-be-uploaded mark for the corresponding file.

Since each application, such as a video player, a music player, and a picture browser, needs to be accessed, each will add an "is _ upload" column, and then the Android framework layer will upgrade this accordingly. The method comprises the following steps: and adding a new function getIsUpload, wherein the function interface can obtain the information whether a certain media file user needs to upload or not by using a naming rule for obtaining the file ID and the path and a method for newly creating the function getIsUpload.

Therefore, before step 101, the method further comprises: modifying the Android frame layer code and upgrading the media database; the specific operation is as follows: add getisappload function and add "is _ upload" column in the database table.

After the Android frame layer code is modified and the media database is upgraded, a new media database is generated according to the modification of the Android code, and an added 'is _ upload' column is used for marking a file to be uploaded, namely, the function of marking whether the file is to be uploaded or not by a user is supported, so that the operation of uploading the file after the mobile terminal is connected with a PC (personal computer) end by the user is facilitated.

The setting of the to-be-uploaded mark in step 101 may be implemented by providing an interactive interface for a user, and the specific implementation method may be various, for example: adding an item of 'waiting to upload' in the menu operation for the media file can be determined according to different application interface styles. Here, as an example of an interface model for adding a to-be-uploaded list to a certain mp3 file, as shown in fig. 2, when an item "to-be-uploaded" is selected in the right menu of "example 1.mp 3", the file is added with a to-be-uploaded flag.

Further, storing the file with the mark to be uploaded and the corresponding file address in a specified directory of the mobile terminal in a list form of the file to be uploaded;

specifically, a list file with a certain format may be generated in a specified directory of the mobile terminal, and a file address to be uploaded with a mark is recorded as a file list to be uploaded, as shown in table 5, the file format of the list file needs to be a file that can be identified by the computer device, and which files in the currently connected mobile terminal need to be uploaded can be known through file names.

Filename	Address
		example1.mp3	/sdcard/download/example1.mp3
example2.txt	/data/data/example2.txt
		example3.ape	/zte_file/example/example3.ape
exampe4.mp4	/tmp/file/exampe4.mp4

TABLE 5

102, selecting uploaded files from files with marks to be uploaded, and sending the selected uploaded files to computer equipment;

specifically, when the mobile terminal is connected with the computer device, the computer device sends a request for acquiring device data to the mobile terminal; after the mobile terminal is connected, the mobile terminal and the computer equipment can communicate according to an MTP protocol; here, the user of the MTP includes two parts, an Initiator (Initiator) and a Responder (Responder), as shown in fig. 3. Wherein, initialter refers to USB Host, for example, a PC, a notebook, and other computer devices; the Responder refers to a portable mobile terminal such as a mobile phone and a tablet computer.

When the mobile terminal is connected with the computer equipment, the computer equipment sends a request for acquiring equipment data named GetDeviceInfo; the mobile terminal may listen to the request, and based on the request, the computer device reads the list of files to be uploaded stored in the designated directory of the mobile terminal, locates the file with the flag to be uploaded, and displays a corresponding interface to prompt the user whether to upload the file with the flag to be uploaded, where a similar interface prompt may be as shown in fig. 4. In practical application, the prompt interface can prompt the user at the mobile terminal or can be displayed on the computer device. After the uploading, when the mobile terminal is connected to the computer device next time, the prompt interface still displays all the files with the to-be-uploaded marks set in step 101 for the user to select.

The selected file to be uploaded can be a file with part or all of the marks to be uploaded, and the mobile terminal sends the selected file to the computer equipment to finish the file uploading from the mobile terminal to the computer equipment.
