android-5.0-lollipop

问题 I'm looking to stop/dismiss a foreground notification for a service for a mediaplayer, much similar to Google's implementation for Google Music. For instance in Google Music, if you are playing music then the the notification cannot be swiped away. However if you pause the music it can. This is completely different to how it is implemented on Android 4.4, where the notification starts only when you leave the app and removes itself when you go back into the app. I can't see how to implement

Here is an example of the primary color

问题 I have a shared element in a fragment that belongs to one Activity. I want to make a shared element transition in Android Lollipop with an element that is part of a fragment that belongs to another activity. Is it possible? How can I achieve that? 回答1: It's possible. First, when you detect in your fragment that transition is about to happen, build a array of Pair<View, String> which you populate with view and transition name. For example, if you want to animate from thumbnail image to full

问题 Excluding the fact that JobScheduler only supports API > 21 - are JobSchedulers designed to fully replace SyncAdapters ? Or does SyncAdapter contain any functionality lacking by JobScheduler ? My use case is syncing an RSS feed every couple of hours. This is doable with a JobScheduler - right? 回答1: I would say JobScheduler is not a direct substitution for SyncAdapter , which has a much more specialized purpose (transferring data between the device and a server). JobScheduler , on the other

问题 My app is taking 10-12 sec delay while first load on 5.0+ devices, 4.4 or below devices does not have this problem.
