    <p>I am trying to make a background service which should measure traffic usage of various applications so as to be able to show to the user which apps consume most data traffic.</p> <p>I found that Spare Parts app does exactly that, but after installing it on a 1.6 Dell Streak device I always get "No battery usage data available" for "Network usage". Does this function at all work in Spare Parts? Also, I couldn't find a working source code for Spare Parts. </p> <p><a href="https://android.googlesource.com/platform/development/+/froyo-release/apps/SpareParts" rel="nofollow noreferrer">https://android.googlesource.com/platform/development/+/froyo-release/apps/SpareParts</a><br> looks to be outdated or incomplete. (?)</p> <p>But Spare Parts seems to measure e.g. CPU usage per app. How does it do that on an unrooted phone? </p> <p>My general idea of how traffic per app could be measured is to regularly check the </p> <p><code>"sys/class/net/" + sWiFiInterface + "/statistics/rx_bytes"</code></p> <p><code>"sys/class/net/" + sWiFiInterface + "/statistics/tx_bytes"</code></p> <p><code>"sys/class/net/" + sMobileInterface + "/statistics/rx_bytes"</code></p> <p><code>"sys/class/net/" + sMobileInterface + "/statistics/tx_bytes"</code></p> <p>files and to see which app currently has focus and thus most likely to cause the generated network traffic.</p> <p>Unfortunately I can't find how to get the app currently having focus.</p> <p>I found this:</p> <p><a href="https://stackoverflow.com/questions/1558750/android-how-to-get-information-on-which-activity-is-currently-showing-in-forego">Android, how to get information on which activity is currently showing (in foregorund)?</a></p> <p>but seems it's about testing, not just a 3d party service running on non-rooted Android device.</p> <p>We can get what activities are running with <code>ActivityManager.getCurrentTasks()</code>, but any of them can be the one with focus. It seems like the Android architects explicitly don't want 3d party apps to know what app has focus, because of security concerns </p> <p>(see <a href="http://android.bigresource.com/Track/android-zb2mhvZX4/" rel="nofollow noreferrer">http://android.bigresource.com/Track/android-zb2mhvZX4/</a>). </p> <p>Is there a way around this?</p> <p>Also, if I want to not only detect which activities eat up traffic but also what services, I can get all currently running services with <code>ActivityManager.getCurrentSerives()</code> and even see for each one if it's in foreground mode (unlike to be thrown out if Android needs resources). But this again doesn't bring me any far.</p> <p>Any ideas?</p>

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.
