I would like to make a game out of many cubes and am planning on putting it on mobile platforms and also on the web using webgl. My problem is when I make a drawelements call per cube I take a hit on the frame rate. Is there a way I can make a single draw call to opengl es to draw them? The only difference between the cubes would be position and color.

I have been able to draw a map using 'MapActivity' class. Am unable to render 3D graphics on the Map. Is there any way to draw something on the foreground with the Map as the background?
View 2 Replies View RelatedI need to populate a View with a data from adapter which contains some number of strings. The problem is that I don't know how many of the strings will be there. So my idea was to use LinearLayout to store data. But even if I reserve enough space for this data (eventually I will draw it in ScrollView), LinearLayout use only horizontal perspective (drawing Strings to the end of line), and not uses additional space beyond.
My intention is to draw to the end of line, and draw next line... till end of data.

How can I utilize Connection: Keep-Alive option, re-use connection and download multiple objects from the same server? HTTP connection consists of opening a socket, sending request and then readign response. For Keep-Alive option open the socket connection needs to be done only once. However I could not find in Android Java classes how this can be accomplished. URL.openConnection returns new instance of HttpURLConnection implementation for every request so HttpURLConnection cannot be cashed for reusing on multiple requests to the same server, URL object is also new for each request and also cannot be reused.
View 2 Replies View Relatedi need to parse this response in android using the android json parser but the thing i cant find the answer to anywhere is: how do i parse the data if for example "itineraries" can contain one or sometimes more objects of the type itinerary? if it contains one than it is returned like this but if it contains more it is returned with [] with this example "itinerary" cannot be placed into a JsonArray becouse obviously it is not an array.

how do i parse this? any examples?

I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?

The FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................
View 7 Replies View RelatedI have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.

I am using the default simulator, Can I make simulator identical to some common device I mean one identical to HTC, one identical to droid motorla, one of samsung, dell, acer,..etc Here identical I mean all the features that it provide.
View 3 Replies View RelatedI have purchased 3 Samsung Galaxy Nexus devices for my family, and one for myself. I wanted to setup all our devices for them and pre-install essential apps for them, and lay it out in a way which makes each device identical so that my family (which is new to Android) can all get the same easy experience from their devices, rather than everyone getting a different LG/Samsung/HTC device and having to deal with differences in skins every time someone phones me with a question about their device.
Here is what I have done:
1. Unlocked bootloader, root, installed CM10.1.2 + gapps onto my own personal device. Clean install, wiped everything.
2. Setup android with a temporary Gmail account, installed about 20 apps, setup the homescreen, changed a few settings for simplicity, change wallpapers, etc.
3. Once I was satisfied, I removed the google account, rebooted to recovery (CWM 6.0.3.2) and made a Nandroid backup which was later copied to my home server.
4. Unlocked Bootloader, rooted and installed CM10.1.2 + gapps on all the other devices, booted the device then transferred the Nandroid backup from my home server to each of these other three devices. Restore the backup, reboot, all seems fine so I setup new individual google accounts, and away I went. Everything works fine, at least so it seems.
Now the issue is that I'm having came a day or two after I got everything setup on each device. At the moment I'm having serious issues with the Google Play Store and Push Notifications. Almost all devices intermittently have issues with this. The play store issue I'm getting is [RPC:S-5:AEC-0], and prevents me from downloading or updating apps. Push notifications is not working either. For example, Google hangouts notifications don't notify me of messages on devices intermittently unless I manually check the app. Same goes with facebook and snapchat notifications. Very annoying. Tried all sorts of fixes such as removing the Google account, rebooting and adding it again, but no luck.
I changed the Android ID on each device hoping that would work, but still no luck.
Edit: Tried making a titanium backup of one device and moved it to a rooted Galaxy S2 running CM10.1 nightlies, and no such issue. Also, updated one nexus device to the latest nightly, still no fix.
I have used both ROMS and they appear to be almost identical. am i missing something. The shadow settings and C6 settings and menu look exactly the same.

View 3 Replies View RelatedHow do I create non-mutually exclusive apks for identical apps that differ only in content? I have an app that plays an mp3 file embedded as a raw resource.

View 9 Replies View RelatedI just spent half an hour going through each file in the OTA upgrade ZIP and comparing its CRC (checksum) to the same exact file in the "leak v3" PB00IMG.ZIP, including all of the files inside system.img. Process: First off, just by opening the two ZIP files with 7-Zip I can see that the boot.img, radio.img, and recovery.img are identical. In both ZIPs, their CRCs are EA7388FA, 54C41EEC, and 3F0153F1 respectively.
Since the OTA breaks down system.img into just the files that need updating (for the purpose of keeping the file size as low as possible), the only way to compare the files with system.img in "leak v3" was to use the root ROM created from "leak v3". (Thank goodness there's an unadulterated ROM of it, so the original CRCs are intact!) One by one, I compared the CRCs of the files in the OTA's system folder with the same files in the "leak v3" system folder. Findings: The files that are in the OTA are completely identical to the ones in the leak v3 system.img, with only one exception: The OTA contains an additional app called UpgradeSetup.apk. Obviously, it's only necessary for executing the upgrade..............
In my app I am drawing bus routes on top of a MapView. The routes have anywhere between a dozen and a few hundred GPS coordinates that describe the route that the bus takes. The problem I'm having is that once I draw out all these lines panning/zooming the MapView is incredibly slow (even clicking the 'Back' button takes a minute to happen). I'm not sure how relevant it is, but I put in some debug code then checked the logcat output and the MapView is repeatedly calling the draw() method of the Overlay whether anything has changed or not. This is happening several times a second and is causing a massive amount of garbage collection to happen (2-3 MB every second).

My application requires that when a snapshot is taken it must store in memory and next time when I restart the phone I must get a thumbnail of that photo in list of photos and the full scale photo when I click on it.There are 2 ways I know.
1. Store images directly. Concern here is every time it has to hit directory to get image which takes some time.
2. Store all images in single xml. Concern here is XML will be too big and takes time to parse.

I've put the rest of the code for both of my classes here, as it's rather large to paste inline.
Once the whole data set is loaded, scrolling up & down causes rows to disappear and re-appear too.
Currently I'm using a HashMap to map the strings to int and the int values need to be frequently accessed. I'm looking for a better way to do this if possible with minimal object creation, and preferable being able to store the values as primitive ints without wrapping them with the Integer class. (Basically, the reverse of the SparseArray's int->object mapping.)
