The following sections detail bug report components, 37 describe common problems, and give helpful tips and <code>grep</code> commands 38 for finding logs associated with those bugs. Most sections also include examples 39 for <code>grep</code> command and output and/or <code>dumpsys</code> output.</p> 40 41 <h2 id="logcat">Logcat</h2> 42 <p>The <code>logcat</code> log is a string-based dump of all <code>logcat</code> 43 information.

You can use the 876 information in the bug report to sync timelines across multiple logs and 877 determine the exact timestamp of the bug report.</p> 878 879 <h3 id="timelines">Syncing timelines</h3> 880 <p>A bugreport reflects multiple parallel timelines: system log, event log, 881 kernel log, and multiple specialized timelines for broadcasts, battery stats, 882 etc. Unfortunately, timelines are often reported using different time bases.</p> 883 884 <p>The system and event log timestamps are in the same timezone as the user (as 885 are most other timestamps). For example, when user taps the home button, the 886 system log reports:</p> 887 <p><pre>10-03 17:19:52.939 1963 2071 I ActivityManager: START u0 {act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10200000 cmp=com.google.android.googlequicksearchbox/com.google.android.launcher.GEL (has extras)} from uid 1000 on display 0</pre></p> 888 889 <p>For the same action, the event log reports:</p> 890 <p><pre>10-03 17:19:54.279 1963 2071 I am_focused_activity: [0,com.google.android.googlequicksearchbox/com.google.android.launcher.GEL]</pre></p> 891 892 <p>Kernel (<code>dmesg</code>) logs use a different time base, tagging log items 893 with seconds since bootloader completes. To register this timescale to other 894 timescales, search for <em>suspend exit</em> and <em>suspend entry</em> messages:</p> 895 <p><pre><6>[201640.779997] PM: suspend exit 2015-10-03 19:11:06.646094058 UTC 896 897 <6>[201644.854315] PM: suspend entry 2015-10-03 19:11:10.720416452 UTC</pre></p> 898 899 <p>Because kernel logs might not include time while in suspend, you should 900 piecewise register the log between the suspend entry and exit messages. 901 Additionally, kernel logs use UTC timezone and must be adjusted to the user 902 timezone.</p> 903 904 <h3 id="time-of-bugreport">Identifying bugreport time</h3> 905 <p>To determine when a bugreport was taken, first check the system log (Logcat) 906 for the <code>dumpstate: begin</code>:</p> 907 <p><pre>10-03 17:19:54.322 19398 19398 I dumpstate: begin</pre></p> 908 909 <p>Next, check the kernel log (<code>dmesg</code>) timestamps for the <code>Starting service 910 'bugreport'</code> message:</p> 911 <p><pre><5>[207064.285315] init: Starting service 'bugreport'...</pre></p> 912 913 <p>Work backwards to correlate the two events, keeping in mind the caveats 914 mentioned in <a href="#timelines">Syncing timelines</a>.
