I'm an application developer, trying to develop a graphics application. I have been trying to get multiple windows each rendering their view up for quite sometime with no headway. I have gone through the documentation but have not come across any technique to enable multiple window support. Does Android have multiple window support as of now?

View 18 Replies View Relatedhow to enable SVG support when building Webkit for Android? I saw an earlier thread from back in March about SVG being slow for the UI of apps, but I'd like to experiment with web content containing SVG, DOM manipulations, etc to see what the speed is like. Is it just a matter of turning on the compile flags for SVG support in Webkit or would there be a significant porting task?
View 2 Replies View RelatedI have a scenario where I start a Service from a splash screen. If I intentionally cause problems in that Service (such as an invalid port for the Socket connection) my UI Thread locks up. I have put a Timer in the Service, and have it perform logging at every tick. The Timer works from within the Service without flaw. So from that, I think I have determined that only the UI Thread is suffering.
If I start a Service from an Activity and that Service has an issue (i.e. server connection problems), should that result in a lockup in the UI thread from which it was launched?
Is there a technique for starting a Service and having it truly run in the background?
I have a galaxy s3 mini running cm11. It does not support exposure lock ( isAutoExposureLockSupported returns false). Is there any way to enable exposure lock and also white balance lock as it seems to be a software limitation. I have searched around and cannot find where the file that contains these parameters about exposure, focus, white balance, etc. Could I change the isAutoExposureLockSupported=true to achieve exposure lock. The camera also seems to not support many focus modes which have been common to all lower end phones I have owned, and also exposure lock was supported on these too.

View 15 Replies View RelatedSo I'm trying to make sure my apps are compatible with the 1.6 SDK emulator skins WVGA800 and WVGA854. The Android Developers Blog post regarding this seems strange to me. The post talks about upgrading your app using the 1.6 SDK, then says this:
"Note that not all devices will be upgraded to Android 1.6 at the same time. There will be significant number of users still with Android 1.5 devices. To use the same apk to target Android 1.5 devices and Android 1.6 devices, build your apps using Android 1.5 SDK and test your apps on both Android 1.5 and 1.6 system images to make sure they continue to work well on both types of devices."
Now resource directory qualifiers (e.g. "res/drawable-mdpi/" or "res/ layout-large") don't work with the 1.5 SDK. So right now as a dev I have the choice to either:
1) Update my apps with the 1.6 SDK so that they are compatible with the various 1.6 emulator skins and the various hardware configurations coming out. If I do this, the updates will not be available to those users that still have 1.5, which is a "significant number of users."
2) Continue using the 1.5 SDK, without the available tools in 1.6, but try to somehow get my app to render properly in the various 1.6 emulator skins.

I am having an issue understanding how to get Bitmaps from resources in density specific directories to scale properly when drawing them to a Surface View.If I have a resource in folder "drawable" I expect it to be scaled up when run on hdpi screens and scaled down on ldpi screens and left as is on mdpi or 1.5 screens.Likewise I expect anything found in hdpi when run on an hdpi screen to remain unscaled. However, there is some combination of settings that I am not getting right to do this seemingly simple thing.I am not running compatibility mode so my manifest supports all screen sizes with anydensity=true.I do not understand the BitmapFactory.Options fields of inScaled, inTargetDensity, and inDensity that I am thinking have to be set appropriately and slightly different for each resource decoded depending on which directory they were found in and what screen they are currently run on.
All I have been able to find is that if either inTargetDensity and inDensity are 0, no scaling occurs, but if not, scaling occurs such that inDensity matches inTargetDensity. Is this correct?I have no idea what valid settings are for these fields from the documentation other than ints.What are the integer values for LDPI, MDPI, and HDPI? And how do I determine the density of a resource in order to set this before I decode it? Am I way off base in my approach for drawing bitmaps from various resource directories on various screen sizes?
If I run my android application with htc magic with locale English. I find my application running properly and if I find to run it on Motorola droid with locale Korean, I find even my application(apk) cannot be installed on the device. Do android support different language? Is it because of different language OS version?
View 3 Replies View RelatedIf an android device wants to support multiple cameras, then how does the API support this? Right now the framework API is a simple static method to create an instance of camera Camera.open(). I see couple of options:
1. Using camera.setParameters() to set a name/value pair that instructs which camera to choose?
2. It would be nice and cleaner perhaps if this was done right on the open() method perhaps with additional enum.
Obviously option # 1 would not result in any addition to the API. Does this use sound right to you to support multiple cameras?
I bought this nice minicomputer - MK812 Mini PC Dual-Core Android Camera Mic BT 4.2.1 and I relied on the fact that since there is Android 4.2 installed, I can use switching users, but unfortunately this function is disabled. I need to get it to work.
Of course, I googled. This is what I've already tried: URL....The problem is that this command pm get-max-users returns Unknown command get-max-users. Furthermore, when I enter SetProp fw.max_users 8, it has no effect, even after a reboot. The command pm usernameyouwanthere create-user is also without effect. URL....
App - 4.2 Multiple users feature enabler..This app can't be installed by Google Play (apparently MK812 is not a compatible device). Since I couldn't get APK anywhere to download, I downloaded the source code and compiled it and generated APK. Unfortunately, can't be installed either.I studied the source code and found out that even if i was able to get it installed, it wouldn't have worked anyway, because this app runs similar commands (as those above) instead of the user.
URL....This could be a solution even for Android 4.0 and 4.1. It works, but switching takes too long, because it requires a reboot and this switching is not integrated into the system.

I have a project compiled with and targeting 1.5. I now want to support different screen sizes instead of letting android handle the scaling.That's all I need to do, right? All my layouts are using dip, so it should scale, and I don't want to mess with different size bitmaps just yet.
View 1 Replies View RelatedI want to develop UI of the application which looks similar on all screen sizes. I have gone through the Android developer article regarding this. I am using supports-screen tag but then also the screen is displayed not displayed properly in the larger screens. The screen is displayed properly in HVGA and not in WVGA.
I have developed the application using Android 1.6 and set the minimum SDK version as 4. The application is running properly on HVGA avd but not on WVGA avd. Can I know the reason for it? Is there any solution for this? I want that the user interface of the application should look uniform in all the handsets.

If yes, I want to know how this is being handled within the Android Stack code. Since the platform code is open source, any suitable reference to any portion of the code handling this behavior would be perfect.

View 3 Replies View RelatedI am trying to develop an app for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things:
1. Mention support for different screen sizes (large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/ mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same. e.g. I ran the app on three emulators 1. Resolution 240*320 dpi 120. 2. Resolution 240*320 dpi 160. 3. Resolution 240*320 dpi 240. (All the emulator have same resolution but different density). The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it necessary that I provide layouts for all combinations of dimensions and density i.e. in layout-small, layout-large, layout- medium, layout-long,layout-notlong?
I was wondering if the Evo supports multiple exchange accounts. I have a coworker that has a stock nexus one and he is able to add multiple exchange accounts effortlessly. I know that there are alternative solutions like touchdown and roadsync but why would a stock nexus one be able to and we are not. I would rather not have to install a 3rd party app to get the same experience. Is this a limitation of our version of android or did HTC take this out?

My only issue is the Droid Inc doesn't support more than one exchange accounts and I have 6. I have read that the original Droid did support multiple exchange accounts, but haven't seen if the droid x does or not. Before I go through the trouble of ordering one and waiting on it to come in, can anybody confirm or deny if the droid x does support multiple exchange account and if so, is there a limit to that number.

View 6 Replies View RelatedI have a few scenarios where I guess I am not alone with. There is no easy solution but this has to be on top of the list I think.
1. Suppose you have an application that is compiled with 1.5 and is working fine even if started on a 1.6 device. But you now want to support other resolutions, so you need to compile with 1.6. Problem: If I recompile and publish the new apk, the 1.5 users want see my applications. Users already downloaded my application can not upgrade. (will there be a "new version" available shown to them in the market?)
2. Lets say your application works fine on 1.5 and 1.6 and you decided to publish your application twice with different package names. "MyApplication 1.5" and "MyApplication 1.6" for example. Problem: The user upgrading from a older version does not know that there is a new version, because you published a new Application. You can write it into the description and tell the user to download the 1.6 version but many users might not read that Settings from the other application are lost. Your downloads are split into two applications, so you might not make it into the top ranks that easy . You might even need to publish 4 applications if you have a light and a paid version.
3. Now 2.0 SDK is available and you want to add multi touch features or any other new stuff for all 2.0 users. Problem: The above problems are getting even worse. There is no way to easily upload multiple apks for the same application. Having to rename the package is also not making this better. Every time svn freaks out and marks everything as new. Sharing code between versions is difficult because of that.
I don't know if its just "3" (provider in Austria), but I still have not received an official update to 1.6. Testing on the real device is not possible with a 1.6 image if you don't want to root your phone and update the rom manually. 2.0 will be on some devices soon, so there is definitely a need to support all 3 versions. There should be a faster update cycle for the users or a slower update of new versions meaning bigger steps. or We get an easier way to support multiple versions. This also means we need a way to know how many actual devices with version 1.5 / 1.6 / 2.0 are already sold and/or upgraded. If i know that 1.5 is only on about 5% of the devices left, then I can just stop supporting that version and upgrade.
