android program to copy music directory Himalayas

My Huawei cell phone (other Android phones should also be usable), built-in music player, Bluetooth can directly control playback stops. This feature is very convenient, especially do not want to dig the phone, press the play button Bluetooth car will be able to play, up and down keys can also switch songs. Open Huawei music - "Setting the Bluetooth control can also be directly controlled Bluetooth headset.

But the play control is Huawei's own music player, built-in music player and very few resources. And many are charging, Himalayan resources are very rich, so would be able to download audio Himalayas, copied to the music player just fine.

But the problem came, the Himalayan hidden directories deep. Every time it went very, very hard to find, and download the file name must also mess batch rename, rename and then copy the music catalog to Huawei.

I like to listen to some continuous program, do so every time a troublesome operation, I feel too much trouble. My lazy relapsed, write a program it. Function is very simple, is to enter the directory name, such as downloading the Three Kingdoms, Three Kingdoms in the input box will create a subdirectory of the Three Kingdoms in the Music directory, download a complete album, you can execute a program, copy the downloaded file past .

If the file does not copy the past, check to see whether there is a default Himalayan downloaded files directory

• Found at the top of [my] interface [Setup] option and click

• [Click Next to download and cache settings] -> [download location], where you can see the audio cache location.
