    <p>Get the string of all log messages as posted in the answer you mentioned. Then, simply search the string using regular expressions.</p> <p>For example, </p> <pre><code>String result = //... get the logs ... if(result.contains("trigger text i am looking for")){ myObject.raiseEvent(); } </code></pre> <p>EDIT</p> <p>If you are trying to do a constant monitoring of the logcat, this will be much more difficult. For one, the process might get shut down without warning. So you need a way to keep it running, or to constantly check that it is running.</p> <p>Secondly, the solution you linked to would not work in this case, as that waits until stopLogging is called, then returns the entire log for the recorded interval.</p> <p>Also, you'll have to modify that code so that it has a list of trigger words and their associated callback functions to run.</p> <pre><code>while ((line = reader.readLine()) != null){ for(int i =0; i &lt; triggerList.size(); i++){ TriggerPhrase trigger = triggerList.get(i); if(line.contains(trigger.phrase)) { trigger.onTriggerPhrase(line); } } } </code></pre> <p>where TriggerPhrase is a simple class that has a String phrase member variable and an object that implements a callback function.</p> <pre><code>public static class TriggerPhrase implements TriggerListener{ String phrase; TriggerListener callback; } public interface TriggerListener{ public void onTriggerPhrase(); } </code></pre> <p>Then before you start listening the logs, you populate the triggerPhrases <code>List</code> in the LogCat listener.</p> <pre><code>TriggerPhrase monkeyPhrase = new TriggerPhrase(); monkeyPhrase.phrase = "monkeys"; monkeyPhrase.callback = new TriggerListener(){ public void onTriggerPhrase(){ notifyUser("found the phrase `monkeys` in the logcat"); } }; triggerPhrases.add(monkeyPhrase); //etc. </code></pre>

    1. COI was looking for a bit more detail on the event raising part. I need to know how I can have another object register for the text it is looking for and also how to notify it that it has been found.

    3. COI will try this out now. Is there anything special I need to do in order to just get logcat info from the point where my app starts up and nothing before?

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.
