curiously on Android there is no button to update the music library, something that at least I remember being implemented in the now “defunct” Symbian, making the task of listening to music much easier by transferring it to our memory card. However, if your smartphone does not update the new songs, there is a solution that can be a bit “crude” but quite effective.
Basically, the operating system creates a file with the information of all the sound files – forgive the redundancy – it finds. Its size varies depending on the music we have in our terminal, starting from about 200 kB and reaching several tens of megabytes. Well, this file called “Media storage” is in charge of updating our music in the library And, in many cases, it must take several hours until it is updated again, so we will not see the changes we have made reflected.
To solve the problem of the music library we will go to “Settings -> Applications -> All”And there we will look for the file that we have just commented and proceed to delete your data. After this, and at restart the mobile, the file will search again for the information of the music saved in our phone and will start updating the library.
In the event that you do not see any changes, it is best to install an application that updates the file automatically. One of the ones that works best is F5-KEY Media Scanner, which runs in the background. Thus, after launching the app, we will see that when we reopen Music, the expected message to update files from the SD will appear.
As you can see, the procedure is quite simple and will allow you to have your entire library updated on your Android smartphone. If it has been useful, do not hesitate to tell us and ask us any questions.
