JP6836059B2 - Music playback device and music playback program - Google Patents

Description

The present invention relates to a music playback device and a music playback program.

The music playback program installed on a smartphone, tablet PC, or the like has its own music database (see, for example, Patent Document 1). The user can set the specified directory as the analysis target. Many music playback programs use a method (white list) that saves the path to be analyzed. In devices equipped with Android (registered trademark) 5.x as the OS, external storage such as an SD card is mounted on a fixed path (for example, / storage / sdcard1). When the user specifies the path, the SD card is recognized as an analysis target even if it is replaced with another SD card.

Japanese Unexamined Patent Publication No. 2005-274790

However, in devices equipped with Android (registered trademark) 6.0 or later as the OS, the SD card was replaced because the mount path of the external storage is the volume name of the storage (for example, / storage / Myname-SDcard). In that case, there is a problem that it is excluded from the analysis target because the path changes.

An object of the present invention is to analyze the external storage even if the external storage is replaced.

It is characterized by adding the existing storage path to the management path to be analyzed.

In the present invention, in the control unit, the management path to be analyzed does not include the path of the mounted storage or less, and the path of the mounted storage is included in the management path to be analyzed. If not, add the mounted storage path to the management path to be analyzed. Therefore, if the management path to be analyzed does not exist below the path of the mounted storage, and the path of the mounted storage is not included in the management path to be analyzed, the storage is Although it is a newly added storage, it is added to the management path to be analyzed. As a result, even if the external storage is replaced and the path is changed, the external storage can be analyzed.

The music playback device of the second invention is a volume in which the analysis target path and the non-analysis target path stored in the control unit as management paths do not exist in the music playback device of the first invention. When the path of is included, the management path is deleted.

Since the newly added storage path is stored as the management path to be analyzed, there is a problem that the management path continues to be stored (remains) even if the external storage is replaced. Therefore, in the present invention, when the analysis target path and the non-analysis target path stored as the management path include the non-existing volume path, the control unit deletes the management path. As a result, the management path does not remain.

The music playback device of the third invention is the music playback device of the first or second invention, wherein the control unit accepts a path of a predetermined folder as a management path to be analyzed based on an operation. To do.

As shown in FIG. 4, when the user unchecks "storage / F842-69C4", the CPU2 sets the folder management path to "/ storage / emulated / 0, ... unselected: /// storage / F842-69C4". Remember.

Hereinafter, the analysis process of the music folder will be described based on the flowchart shown in FIG. The CPU 2 acquires the management path of the stored music folder (S1). The CPU 2 separates the acquired management path into a management path to be analyzed and a management path to be non-analyzed (S2). Next, the CPU 2 acquires the path of the currently mounted storage (S3). Next, the CPU 2 determines whether or not the management path to be analyzed includes a path equal to or less than the acquired storage path (S4). When the CPU 2 determines that the management path to be analyzed does not have a path equal to or less than the acquired storage path (S4: No), it determines whether or not the acquired storage path is included in the management path to be analyzed. Judge (S5). When the CPU 2 determines that the acquired storage path is not included in the management path to be non-analyzed (S5: No), it determines that the external storage is newly added, and analyzes the volume path of the storage. Add to the management path of (S6).

Next, the CPU 2 determines whether or not all the volumes have been inspected (S7). When it is determined that the inspection of all the volumes has not been completed (S7: No), the CPU 2 performs the process of S3. When the CPU 2 determines that the inspection of all the volumes has been completed (S7: Yes), the CPU 2 ends the process.

When the management path of the analysis target includes a path equal to or less than the acquired storage path (S4: Yes), the CPU 2 performs the process of S7 assuming that the user has already operated and specified the analysis target. .. When the CPU 2 determines that the acquired storage path is included in the management path to be non-analyzed (S5: Yes), the CPU 2 performs the process of S7 to indicate that it has been set as the non-analysis target in the previous user operation. Do.

In this way, the CPU 2 determines the new storage, and if it is a new storage, it considers it as a management path for analysis handling.

As described above, in the present embodiment, in the CPU 2, the management path of the analysis target does not include the path of the mounted storage or less, and the path of the mounted storage is the non-analysis target. If it is not included in the management path of, add the path of the mounted storage to the management path to be analyzed. Therefore, if the management path to be analyzed does not exist below the path of the mounted storage, and the path of the mounted storage is not included in the path to be analyzed, the storage is new. The storage was added to, but it is added to the management path to be analyzed. As a result, even if the external storage is replaced and the path is changed, the external storage can be analyzed.

Here, since the newly added storage path is stored as the management path to be analyzed, there is a problem that the management path continues to be stored (remains) even if the external storage is replaced. Therefore, in the present embodiment, when the analysis target path and the non-analysis target path stored as the management path include the path of the volume that does not exist, the CPU 2 deletes the management path. As a result, the management path does not remain.
