Android library for working with last.fm API

lastfm-library

Gradle:

compile 'com.github.ag:lastfm-library:1.0.2

#Usage

1. Add the internet permission in your AndroidManifest.xml

   <uses-permission android:name="android.permission.INTERNET" /> 

2. Add this to the resource file (example strings.xml).

   <string name="api_key">your_api_key</string>

   If you want to use methods that require authorization add your API secret to the resource file (example strings.xml).

   <string name="secret">your_api_secret</string>

3. Initialize library on startup using the following method. Call it inside onCreate method of your Application class.

   public class TestApplication extends Application {
   
    @Override
    public void onCreate() {
        super.onCreate();
        //Initialize here.
        Lfm.initializeWithSecret(this);
        //You can initialize without secret,but remember that you cannot use methods that require authentication.
        //Lfm.initialize(this);
   
       }

}

# API Requests
1. Plain request.

```java
LfmRequest lfmRequest = LfmApi.user().getInfo();
 ```
2. Request with parameters.

```java
 LfmParameters params = new LfmParameters();
 params.put("artist","The artist name");
 params.put("track","The track name");
     
 LfmRequest request = LfmApi.track().getInfo(params);

3. Track scrobble.

   Remember : This method requires authentication. It means that you should use API secret when initializing library at the beginning.

   ScrobbleParameters params = new ScrobbleParameters();
   params.put("track","track1","track2","track3");
   params.put("artist","artist1","artist2","artist3");
        
   String timestamp = String.valueOf(System.currentTimeMillis()/1000);
   params.put("timestamp",timestamp,timestamp,timestamp);
        
   LfmRequest trackScrobble = LfmApi.track().scrobble(params);

Requests Sending

 request.executeWithListener(new LfmRequest.LfmRequestListener() {
    @Override
    public void onComplete(JSONObject response) {
         //Called if there were no errors
    }

    @Override
    public void onError(LfmError error) {
        //Called immediately if there was API error, or  if there was an HTTP error
    }
});

User Authorization

Remember : Use Lfm.initializeWithSecret(Context context); method when initializing library at the beginning if you want to use user authorization .

Lfm.login("username", "password", new Lfm.LfmCallback<Session>() {
    @Override
    public void onResult(Session result) {
        // User passed Authorization      
    }

    @Override
    public void onError(LfmError error) {
        // User didn't pass Authorization
    }
});
