    <p>I would like to write an application (for research) that makes a timestamp every time the battery level changes. If I can't do that, I want to make it so it takes a battery reading every 10 or so minutes. </p> <p>I have this <code>BroadcastReceiver</code> code but I am not sure where to put it.</p> <p>My application keeps crashing with the following exception:</p> <blockquote> <p>java.lang.RuntimeException: Error receiving broadcast Intent { act=android.intent.action.BATTERY_CHANGED flg=0x60000000 (has extras) } in com.mdog.datareceive.Receive$1@43c9cd10</p> </blockquote> <p>In the <code>onCreate</code> of my activity I spawn 3 AsyncTask threads that do stuff in the background. Where would be a good place to put the broadcast receiver? </p> <p>I have tried in the <code>onCreate</code> and I have tried in a new method that gets called by one of the background tasks. I think the problem might be that the function the <code>BroadcastRecevier</code> code is in might be ending prematurely? </p> <p>Is there anyway I could put it in its own thread so that it just waits for broadcasts?</p> <p><strong>Code:</strong></p> <pre><code>batteryLevelTimeStamps = new LinkedList&lt;String&gt;(); BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver(){ @Override public void onReceive(Context context, Intent intent){ int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1); int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1); int level = -1; if (rawlevel &gt;= 0 &amp;&amp; scale &gt; 0) { level = (rawlevel * 100) / scale; } batteryLevel = level + "%"; batteryLevelTimeStamps.add("At time: " + new Date().toString() + " the battery level is:" +batteryLevel); out.print("At time: " + new Date().toString() + " the battery level is:" +batteryLevel + " in onCreate\n"); } }; IntentFilter batteryLevelFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED); registerReceiver(batteryLevelReceiver, batteryLevelFilter); </code></pre>

    2. COI'm aware, I am testing the characteristics of battery drain. The phone will actually be awake for the entire duration of the test.

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.
