Abstract: Methods and devices are provided for establishing a classic Bluetooth connection between dual-mode Bluetooth devices. In one aspect, a method includes receiving, by a first dual-mode Bluetooth device, a Bluetooth low energy advertising packet sent by a second dual-mode Bluetooth device; determining, by the first dual-mode Bluetooth device, a status of the classic Bluetooth of the second dual-mode Bluetooth device according to the Bluetooth low energy advertising packet; and prompting, by the first dual-mode Bluetooth device according to the status of the classic Bluetooth of the second dual-mode Bluetooth device, a user to operate the first dual-mode Bluetooth device or the second dual-mode Bluetooth device to establish a classic Bluetooth connection between the first dual-mode Bluetooth device and the second dual-mode Bluetooth device.

Abstract: Embodiments of the present disclosure provide, for example, a Bluetooth connection method, the example method including sending, by a first terminal, a Bluetooth low energy BLE advertising message, where the BLE advertising message includes device information. A second terminal receives the BLE advertising message, and then obtains the device information. The second terminal then matches the device information with prestored device information and, if the device information successfully matches the prestored device information, initiates a classic Bluetooth connection request to the first terminal, where the first terminal then establishes a classic Bluetooth connection to the second terminal. Power consumption of BLE is low.

Abstract: The present application discloses an ANDROID system-based folder management and display method and mobile terminal. The folder management method includes: acquiring a selected instruction that is generated after a to-be-processed folder is selected from a folder displayed on a display interface; generating, according to the selected instruction, a display attribute file for hiding the to-be-processed folder; and storing the display attribute file in the to-be-processed folder, so as to hide the to-be-processed folder, which stores the display attribute file, from the display interface when the to-be-processed folder is read and recorded and it is further determined that the to-be-processed folder stores a corresponding display attribute file. The present application can effectively solve a technical problem, in the prior art, that it is hard to simply, rapidly and effectively hide a folder.
