    <p>I'm making a simple mediaplayer app that downloads a song from a predetermined URL then let's the user play, pause and stop the song, among other things. My only problem right now is that if the user tries to play the song before they download it the application force closes. </p> <p>My first instinct is to create a global bool flag, set it to true when my download service downloads the file, and then use that flag to error check before I let the play.onclick button run the play service. </p> <p>So for example:</p> <pre><code>play.setOnClickListener(new OnClickListener() { public void onClick(View v) { if (downloadFlag == true){ Intent intent = new Intent(getApplicationContext(), PlayService.class); intent.putExtra("key", 0); intent.putExtra("nkey", 0); startService(intent); String artistFirst = url.substring(url.lastIndexOf('/')+1, url.lastIndexOf('_')); String artistLast = url.substring(url.lastIndexOf('_')+1, url.lastIndexOf('-')); String song = url.substring(url.lastIndexOf('-')+1, url.lastIndexOf('.')); tv_artist.setText("Artist: "+artistFirst+" "+artistLast); tv_song.setText("Song: "+song); final ImageView album = (ImageView) findViewById(R.id.imageView1); album.setImageResource(R.drawable.album); } } }); </code></pre> <p>Is this a good way to approach this problem or should I pursue a more elegant solution? </p> <p>Edit::Solution found</p> <p>At start of the application I disable the play button and then enable it in my broadcastreceiver (which catches when the download finishes)</p> <pre><code> Button play = (Button) ((Activity) context).findViewById(R.id.play); play.setEnabled(true); </code></pre>

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.
