    <p>I'm trying to edit the build.prop file by replacing 3 lines in the file. The following method leaves the original lines and copies the new ones to the new file. I need to replace the lines instead of adding new.</p> <p>I've updated my code to use the "else if" shown below</p> <pre><code>/**Changing build.prop values here * @throws IOException */ public void PropEdit() throws InterruptedException, IOException { String origFile = "data/data/vzw.versatile1.props/build.orig.prop"; String propFile = "data/data/vzw.versatile1.props/build.new.prop"; try { suProcess = Runtime.getRuntime().exec("su"); DataOutputStream os = new DataOutputStream(suProcess.getOutputStream()); os.writeBytes("chmod 777 /data/data/vzw.versatile1.props/build.new.prop\n"); BufferedReader in = new BufferedReader(new FileReader(origFile)); PrintWriter out = new PrintWriter(new File(propFile)); String line; String params []; while ((line = in.readLine()) != null) { params = line.split("="); if (params[0].equalsIgnoreCase("ro.product.device")) { out.println(params[0] + "=" + "Maguro"); /**out.println(line); **/ out.flush(); } else if (params[0].equalsIgnoreCase("ro.product.name")) { out.println(params[0] + "=" + "yakju"); /**out.println(line); **/ out.flush(); } else if (params[0].equalsIgnoreCase("ro.product.model")) { out.println(params[0] + "=" + "Galaxy Nexus"); /**out.println(line); **/ out.flush(); } out.println(line); } boolean successful; { out.close(); in.close(); os.flush(); os.close(); suProcess.waitFor(); } } catch (Exception e) { Toast.makeText(getApplicationContext(), "ERROR: " + e.getMessage(), Toast.LENGTH_SHORT).show(); e.printStackTrace(); } } </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.

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).
