Android Music player Development Sweetmusicplayer Smart load in-line lyrics

use MediaPlayer to play music in a written, http://blog.csdn.net/huweigoodboy/article/details/39862773. What if there is no local lyrics? Now let's load the lyrics online. OK, still use that picture.

In the implementation of this function, LZ tried Baidu API, lyrics fan API, later selected lyrics fan API. Although the resources are still not complete. And there are very many errors.

The special headache is that sometimes lyrics do not branch. It is simply uncomfortable to parse.

Lyrics Fan API lyrics query address: http://geci.me/api/lyric/

For example I want to query: http://geci.me/api/lyric/quiet/Jay Chou

Will get a JSON string:

{"Count": 2, "code": 0, "result": [{"Aid": 2223011, "artist_id": 30796, "song": "\u5b89\u9759", "LRC": "http://s.geci.me/l RC/257/25700/2570058.LRC "," Sid ": 2570058}, {" Aid ": 2336033," artist_id ": 30796," song ":" \u5b89\u9759 "," LRC ":"/HTTP/ S.GECI.ME/LRC/272/27282/2728244.LRC "," Sid ": 2728244}]}

Very easy to find inside the lyrics file. Then buffer to local (sweetmusicplayer/lryics), and then press the local load mode.

We'll go through the following steps when we load the lyrics file.

1) The address of the lyrics is queried by the address.

(Here the landlord with URLConnection)

2) Buffer lyrics file with lyrics address.

(Here the landlord with URLConnection)

3) Load the buffered lyrics file.

Said above seems to be more easy, the landlord himself wrote a demo, is a javaproject, found no problem. Load the lyrics file normally.

Wait until Android, the first step on your knees. Discovering URLConnection's getInputStream () throws an IO exception, which is simply deadly. Toss for a while to find is due to bring http://geci.me/api/lyric/quiet/Jay Chinese path.

Since the default is GBK, the network transmission is utf-8, so the Chinese transcoding. Urlencoder.encode (str, "utf-8");

To the 2nd step, the problem appeared again, the lyrics garbled.

The solution, using the character stream operation is more appropriate, but also pay attention to the same code.
