    <p>So I have a class that will play some songs via the MediaPlayer. I have the following code that When a Radiobutton is selected should play a song, However this does not work, could anyone tell me why?</p> <p>I do not get any errors, the music just does not play.</p> <p>Code from the OnCheckedChange Method:</p> <pre><code> break; case R.id.rFolk1: //setting up sub radiogroup buttons if(fsong1.isPlaying() == false) fsong1.start(); break; case R.id.rFolk2: //setting up sub radiogroup buttons if(fsong2.isPlaying() == false) fsong2.start(); break; </code></pre> <p>Other code for the songs:</p> <pre><code> fsong1 = MediaPlayer.create(this, R.raw.folk1); fsong2 = MediaPlayer.create(this, R.raw.folk2); </code></pre> <p>Fullcode:</p> <pre><code>public class Music extends Activity implements OnCheckedChangeListener, OnClickListener{ Button playpause; RadioGroup selectionList, Folk, Rock, Pop, NewWave, Pipe;//define the radiogroup RadioButton folk1, folk2, rock1, rock2, pop1, pop2, newwave1, newwave2, pipe1, pipe2; //define radiobuttons MediaPlayer fsong1, fsong2, rsong1, rsong2, psong1, psong2, nwsong1, nwsong2, pisong1, pisong2;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
