Currently I'm developing android app uses Camera, SurfaceView, GMaps, GPS and fullscreen mode without ability to rotation.
What I'm surprised about is that sometimes after starting my app I see corrupted layout for cifiral keyboard of my HTC Desire phone.
Here is a screen:
And this is how it have to be if OK:
Could you please explain what is the reason of this strange phone behavior?

I am running an app built in Flutter on Pax A920 device with Android 7.1.2 installed.
Whenever the keyboard appears, the screen jumps down, and shows parts of the current view above the screen. When I dismiss the keyboard, everything goes back to normal.
This behaviour can be seen in the photo below. Sorry for the image quality, I cannot take screenshots on this device.
Photo of the unexpected behaviour
I cannot really show any code examples since this happens every time the keyboard appears, from different screens with different navigation stacks.
This works fine on iOS devices and on the Android emulators I have tried, so clearly this has something to do with the device/OS I'm running this on.
Has anyone experienced this or something similar and has an idea of how to prevent this?
That's pretty much sums up the question. I have an AIR Mobile Flex App project in FlashDevelop that is using views to show content. Everything works fine, I can add a TextInput or TextArea to the stage, select it (Soft Keyboard shows up then), type some text. But when I press enter or change focus to the other element to hide the keyboard, the screen turns completely white except for the text that has been entered in the field.
Now it becomes interesting. If I rotate my tablet to force the screen to adjust, the content becomes again visible. Sometimes it doesn't even show a white screen, but rather a pitch black one that shows a blank preview when looking at the list of the running apps.
I cannot grasp the logic besides this behavior. It seems that somehow screen just doesn't want to redraw.
UPD:
AIR verison: 3.1
Tested on HYUNDAI SmartPad H-SP701G, Android 4.0.4
UPD2:
Tested on SANSUI ETAB 801VP, still getting the same effect.
The problem is in your application configuration XML.
Check your tag.
Entering value of "auto" or "cpu" should fix the problem.
<renderMode>auto</renderMode>
In my case I set direct and this was the cause of the issue. Using direct render mode caused the application to not work on HTC Evo 3D and Samsung galaxy s3. It did work on HTC Desire though.
I've just started to use the SmallApps API of Sony Tablet SDK. I need to show my small app always on the top but when user is opening the screen keyboard small app is making hidden. It possible to solve this problem?
I have this browser launching application which didn't have any problem till now: when it is being tested on Samsung Galaxy 10.1 (Model Number: GT-P7510) with Android 3.1 Honeycomb.
The issue is this: whenever I tap on a text box, the whole screen will flash across a black screen for a moment and revert back to normal. It starts flickering/blinking the black screen when I leave a focus on any text box as well.
Currently, I've no idea what is causing this issue as I've tested this application on several devices e.g. Samsung Galaxy S, Samsung Galaxy Tab 7-inch with previous version of OS from 2.1 to 2.3.
Anyone who has any clue as to what is going on whether be it a compatibility issue with the app or a change in function in honeycomb 3.1 or the device itself, please share your information and enlighten me on this matter please. Any kind of help is greatly appreciated!
Thanks
I'm sorry that this is not a solution, but I think I can shed some light on the problem.
We have recently been testing a functional jQuery Mobile HTML5 app wrapped with PhoneGap Android 2.x phones to the Galaxy tab 10.1. We have seen something very similar, with the exception that we have defined a splash screen for our app. What we see is that when an input field is given focus, the screen flashes up the splash screen momentarily. Very annoying! To verify if this is the same problem, define a splash screen for your PhoneGap app and see if the screen flahes your image instead of a black background. Knowing something about what's going on with PhoneGap and the Android WebView, this is my best estimation of what is happening: PhoneGap loads the main App activity with a black background and displays the splash screen (if defined) in that initial window. PhoneGap then starts the WebView and opens it on top of the main Window. When a field is selected, the Android invalidates the component wach time it updates it based on a focus event or keypress, or whatever, and Android redraws everything. So it redraws the main window behind the WebView and then redraws the WebView with the HTML page content on top of it. Since the device is not properly double-buffered, you see all of this redrawing in all its ugly glory right in front of your eyes.
We have seen serious glitches with Android web forms on some Android 2.x phones we have tested, and this looks like yet another glitch, but this time on the Galaxy Tab running Honeycomb (3.0).
We have attempted to use CSS -webkit-backface-visibility to resolve issues on some phones when experiencing flicker in the past - but this has caused serious rendering issues in HTML forms. Be warned! In theory this should be a viable fix to introduce some double-buffering into the mix, but in our experience it causes more problems than it solves.
I am not confident that this can be resolved, except by an Android software update from Google/Samsung.
At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator.
To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target)
So the procedure to duplicate once the emulator loads is
press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait
Result:
In the homescreen:
The view rotates to landscape, and then back to portrait, as expected
In any app (i've tried browser, calculator, maps, and the app i'm currently working on):
the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below)
Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators
This is a bug with the Android emulator running 2.3.x. Bug is already acknowledged here
Actually, I have run into that problem occasionally before, though it does seem to get progressively worse with each passing tools release. There is nothing wrong with your installation or how you are using the program, AFAIK. You might try using Ctrl-F12 to switch back rather than Ctrl-F11 and see if that improves matters. I think the problem may stem from the emulator trying to emulate four-way orientation, but that is just a guess.
I just got stuck with the same problem in my own application. The app always stays in lanscape mode after using the camera. The only workaround I found is to click on the home button (emulator changes to portrait mode) and then click again on my application to get back to it also in portrait mode.
Did anybody report that bug already?
(Gingerbread emulator, Eclipse 3.5.x, Android Development Tools 8.0.1.v201012062107-82219)
