    <p>i have a php script which creates a file if it not exists. the php script sends the file after it created it. now i have the problem that my download class can't download it (i don't know exactly why) when the php file is creating a new file. but if the php script sends a cached file the download works. Is there any way to let the android wait until the php script is done executing?</p> <pre><code>import java.io.BufferedInputStream; import java.io.File; import java.io.FileOutputStream; import java.io.InputStream; import java.io.OutputStream; import java.net.URL; import java.net.URLConnection; import org.json.JSONObject; import android.os.AsyncTask; import android.os.Environment; import android.os.Looper; import android.provider.ContactsContract.Directory; import android.util.Log; public class DownloadMP3 extends AsyncTask&lt;String, Integer, String&gt; { private OnTaskRunning listener; public DownloadMP3(OnTaskRunning listener){ this.listener=listener; } @Override protected String doInBackground(String... url) { int count; try { Log.d("Info", "create file"); Download down = new Download(); JSONObject jObject = new JSONObject(down.JSON(conf.d + "convert.php?v=" + url[0])); Log.d("Info","json file: " + jObject.get("fle")); URL u = new URL(conf.d + "convert.php?v=" + jObject.get("fle")); Log.d("Info", "dl u"); URLConnection conexion = u.openConnection(); Log.d("Info", "dl op"); conexion.connect(); Log.d("Info", "dl co"); File directory = new File(Environment.getExternalStorageDirectory() + "/Music/VBT Splash/"); Log.d("Info", "dl di"); if (!directory.exists() || !directory.isDirectory()){ directory.mkdirs(); } InputStream input = new BufferedInputStream(u.openStream()); String filename = conexion.getHeaderField("Content-Disposition"); String file = filename.substring(filename.indexOf("\"")+1, filename.lastIndexOf("\"")); OutputStream output = new FileOutputStream(Environment.getExternalStorageDirectory() + "/Music/VBT Splash/" + file); int lenghtOfFile = conexion.getContentLength(); byte data[] = new byte[4096]; long total = 0; listener.onTaskStarted(); while ((count = input.read(data)) != -1) { total += count; output.write(data, 0, count); publishProgress((int) (total * 100 / lenghtOfFile)); } Log.d("Info", "dl done"); listener.onTaskDone(); output.flush(); output.close(); input.close(); } catch (Exception e) { } return null; } protected void onProgressUpdate(Integer... progress) { listener.onTaskProgress(progress[0]); } protected void onPostExecute(int result) { } } </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.
