Solving problems with Android

The sure-fire way to know what Sync on Android is really doing is to observe the Android device log using adb logcat. You’ll want to bump your log-level:

adb shell setprop log.tag.FxAccounts VERBOSE

Then, you can observe the log using:

adb logcat | grep FxAccounts

It’s best to observe the log while you force a sync from the Android Settings App. You should see output like:

D FxAccounts(...) fennec :: BaseResource :: HTTP GET
D FxAccounts(...) fennec :: BaseResource :: HTTP GET
