[android-developers] DisplayInfo and Detecting WiFi displays
Hi, I'm trying to reliably detect when Miracast is used and the screen id mirrored to a WiFi display. I haven't found in the documentation of android.view.Display any indication of whether the display is WiFi or not. However, when I debug the code I see that the Display object has a member of type DisplayType which has the required information. I'm puzzled to discover that in the AOSP sources there is a function in Display class to retrieve this DisplayInfo, as well as in the sources coming with the SDK. So can I use this function and DisplayInfo? Should I use reflection for that? Is it reliable?

Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
@Haris.. You would need to store the GCM- Registration Id in the Database(Server side) so that the Server API/Webservice api/ should able to pick the Registration Id from the DB and send me message to the correct device (Based on the registration id). here is the way i used it. I have an logistics app where in the Admin decide the take a load or do a refresh upon receving the GCM Message. The server db is having a GCM table with the following structure. RegistrationID | DriverId | Message | Status|. xxx | 2113 | Refresh | 1 The data will be pulled by the HTTP request which inturn send the message to the device so that Driver get to know that there is a updated data and it requires to download after downloading the data the APK will update the status back to 3 so that the HTTP request should not pull the same record.

Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
Further to that. . as soon the APK register the device it gets the RegistrationId which inturn store in the Server DB so that the Server can push the messsage. for example; https://myserver/api/updategcmdata driverid=2113 registrationid=x The service will update/create the new record in the DB.

[android-developers] Re: Compass Reading - proper implementation.
On Monday, March 17, 2014 4:40:21 PM UTC-7, Nathan wrote: Last time I worked on a compass reading (which was years ago), I did something like this. A: http://www.javacodegeeks.com/2013/09/android-compass-code-example.html Of course, this example has a locked portrait orientation. So, I call something like this to get it in sync. http://developer.android.com/reference/android/view/Display.html#getRotation() Now, I realize that some of the calls in example A are deprecated. Many devices with which I am familiar, though, it actually does work. That's why, if I were to do a new implementation today, I might consider something like implementation B. B: http://sunil-android.blogspot.com/2013/02/create-our-android-compass.html I have no good way of testing either method on all of today's gazillion Android devices, so I am going to have to use a best practice, and try to blame the user's device when they don't work. So my questions are: 1. Does implementation B already take into account landscape/portrait orientation of the device, or should I continue to use Display.getRotation? 2. Are there known devices for which A fails and B works or vice versa? 3. Are there devices with usable sensors for which neither A or B works? 4. Are there any known drawbacks of implementation B? Nathan To follow up with my question from a several months ago. I can confirm that the deprectated Orientation sensor method (method A above) is broken in some devices. Not just wrong values - no values apparently. Two users at once told me they were getting no compass readings. When two users at once do that, I can expect the problem will soon be widespread. Xperia M2, and Samsung S4 mini. A log file from one showed this: 07-08 21:39:35.103 E/SensorManager(15370): sensor or listener is null I had both implementations in the code, but never really activated method B because of no real testing. I sent custom apk to one of the users, and method B worked. Both method A and method B work on the Galaxy note 3, which I have. Method B is much more jittery, and I expect that is the case in all devices. Don't know how to resolve that yet, and haven't seen gimbal lock yet to comment.

Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
Yes, I believe we are talking about the same key (I did only a brief check on GCM documentation and thought it's called Sender Id, my bad). Still, I am not exactly sure how Google reacts if/once you start sending push notifications from multiple IPs. I tend to think people are usually limiting the IP space allowed to send notifications instead of depending on no filtering takes place at all. But if this is not an issue, I see absolutely no reason why this couldn't work. -- H On Jul 8, 2014 8:39 PM, MS ms.jackspar...@gmail.com wrote: Hi Harri Smatt, Sender Id needs to be in the App to register with GCM server and get the GCM ID.

Re: [android-developers] Re: App memory vs extornal memory
Create a folder on external memory card from application and store those files there. From that location you can access them. If you store them in app memory, then it will increase app size and may through OutOfMemory exception. On Jul 10, 2014 10:10 AM, Rahul Kaushik rahulkaushi...@gmail.com wrote: any suggestions??
