Could you confirm whether this still happens and, if so, provide a heap dump?

We have a service that gets scheduled by GcmNetworkManager every 60 seconds, and we are seeing this false leak a lot.

Here is the method used to schedule this service:

static void scheduleRefresh(GcmNetworkManager networkManager) {
PeriodicTask.Builder taskBuilder = new PeriodicTask.Builder()
.setService(MyService.class)
.setPeriod(60) // seconds
.setFlex(30) // seconds
.setTag(MyService.TASK_TAG)
.setUpdateCurrent(true) // If a task exists already, use it instead of creating a new one.
.setPersisted(false) // The task will be recreated next resume, no need to persist.
.setRequiredNetwork(Task.NETWORK_STATE_CONNECTED);
networkManager.schedule(taskBuilder.build());
}

i had the same issue.. in my case "NO LEAK FOUND" caused by webview. the Webview located in a fragment, and i already put a piece of code like this in ondettach() method
if (webView != null) { webView.removeAllViews(); webView.destroyDrawingCache(); webView.clearHistory(); webView.destroy(); }
but the message still shown ? how can i fix that ?
