Animation flickers on Android device - android

Following up on my previous post on animation trouble (Codename One Animation Trouble (also in Solitaire demo)?) in my app and in the Solitaire demo. The simulator and iOS problems are solved, but there remains the issue on Android devices. (Test: Nexus 7, Android 5.1.1; CN1 3.3.1)
In my checkers app, when the computer makes a move, the checker starts moving but the destination square briefly flashes (while the undo/redo animations work fine). This is similar to what happens in Solitaire: when a card starts auto-moving, but only if it is the second move or higher in a row, the card it will land on top of usually flashes (as if the button is pressed?). This also happens in the deal-from-deck animation (many moves in a row).
In my app it looks like the checker is very briefly (one frame?) shown at the destination location and then it starts moving from the source location to the destination location as it should. The same probably applies to Solitaire.
In issue #1640 you mentioned:
'This is probably related to the Android pipeline work we are doing and has nothing to do with the animation framework. We'll take a look at that and try to figure out what happened there.'
When is the improved Android pipeline scheduled?
Would you like me to submit a new issue for this?

I think this works better with issues ideally with smaller scopes (one issue per post) and ideally with a simple test case the demonstrates the issue.
The issue tracker is probably a better place for bugs than stack overflow.

PhoneGap – Page "zooms" out of viewport by rotation

i'm pretty new to PhoneGap.
For my first project I designed a website with Adobe Muse and built it into an APK with a normal, empty PhoneGap-Project.
It works very well, but when I rotate my Device (it is a tablet and the app is only meant to run on a tablet with Android 5.0) I experience strange problems with my web page "zooming" out of display on the right and the bottom.
And every time I rotate it back and forth, it zooms one step more out of the viewport.

Does someone know this problem - or even better - a solution?
Will be very thankful for every hint!
Edit:
I used PhoneGap-Build.
No plugins or something were used.
I have slider widgets (the ones from Muse) on the pages where the error occurs.

Android screen stops reading inputs

First off, this has never happened before on any other android device I've used (multiple devices have been tried and tested before this).
Now I have an app that I have worked on for a little over a year now, it is called AutomatedId (on the app store) and it has worked quite well for my company for quite some time.
Recently I have been given a device to add compatibility to the app (specifically for reading UHF tags) but that isn't the problem.
The problem comes whenever you open the app, the screen stops reading inputs completely, as well as buttons cease to function. I turned on developer options to see the screen inputs and as i suspected, it completely stops and does not read any of the inputs after the app is opened. Clicks don't work, buttons don't work, keyboard doesn't open, hardware buttons on the device stop working. It's a mess, does anyone know what could have caused this?
This is a S98 from here: http://www.wepoy.com/product_view_18.html
moved my comment to the answer as you said. This may be due to memory leak. Here are some references that may help you fix them: Fixing-Memory-Leaks-in-Android-Studio & use this library from square to detect memory leaks early: leakcanary

Android app on Chrome using ARC, keep back button on top enabled

developer.chrome.com/apps/getstarted_arc#bestpractices
The ARC allows you to execute native android apps through the chrome browser by wrapping a chrome app around it.(As far as I can tell)
I am re-factoring an Android app to work well on Chrome. The first thing I need to do is to make the back arrow enabled at all times on the top left as shown below.
This is the program that allows Native android apps to run through chrome. I think the answer to my question lies somewhere in "Additional Metadata", or in the source code?
Add {"disableAutoBackButton": "true"} to the metadata. That will enable the back button within an activity. I've found that with my app that has multiple activities, though, it doesn't work to return to my main activity from my settings activity. It could be that I'm doing something wrong with the way I'm handling activities, I guess, but it works on all physical devices.
{"sleepOnBlur":false,"disableAutoBackButton":true}
please supply the above metadata before you download the zip or launch app from the arc welder
the first param prevents excessive pause/resume and also supposed to fix short black screen flash occurring occassionally in some of the apps.
the second params adds persistance back button on top left hence helping to avoid extra code required because of absence of back button in some screens(mostly the first screen)

Air for Android: Black Screen after device-alarm

I do have a problem and have very little to go on. I'm about to release an App (created with Air for Android As3) on the Samsung App Store and just got a list of issues that have to be resolved after the app has been tested by samsung staff before the app could be released.
I did manage to solve almost all of the issues, but 1 very important one is beyond me. They say the screen turns/stays black, when returning after the device alarm interrupted the app. This issue practivally happend on all their devices, including a group including the phones I own (e.g. Galaxy S3).
I do have "OnDeActivate" and "OnActivate" listeners in place that are there to pause the app, disable sound etc. if it loses focus, gets minimized etc., yet I checked on my devices and I can't reproduce this error. Meaning if the app gets interrupted on my device by the alarm, I can resume it without any problems. no black screens.
So the question is: Is there any way for me to fix that at all? I do have to work within AirForAndroid AS3 so I guess possibilities are limited. Any clues where I can look? Any listeners to set, or is there a way to maybe "force" the app to reinitialize or refresh the display? Or to listen for the system alarm? Help would be much appreciated. Thanks in advance!
I am trying to overcome the same issue, I read somewhere that setting the stage quality to something else on both the activate and deactivate events might solve the issue.
So just set your stage quality to medium or whatever different in the deactivate and set it back to what it needs to be in the activate.
This should make AIR snap out of that black screen for the alarm (I hope)
An app of mine is with this fix is currently undergoing testing on the Samsung App Store.
I hope it fixes it.
Good news, the dirty fix of toggling the stage quality seems to have worked for Samsung, it has not shown up in their latest certification report of my app.
by the way, this is not for a stage3D app, that's different
It's for a GPU app
When the app loses focus on Android (goes into background) it will lose the context, which among other things mean that you lose all the created graphics, cached objects and like.
You didn't specify what kind of app it is. If you're using Stage3D, that means you'll have to recreate all your textures, and if you're on plain old displaylist, you'll have to recreate any bitmaps that were created at runtime, and redraw your screen at least once (so the vector graphics get redrawn too).
Now, if you're using Starling, for example, it can take care of recreating context for you (there's a flag for enabling that), although you'll still have to recreate dynamically created bitmaps.

How do I fix visible 'invisible-buttons' in Android app port to Blackberry?

I have a very simple Android app. It is one Activity with Text and Buttons, and as you click on the buttons (onTouch events), they become invisible and the text changes.
This works fine for Android 3 and Android 2.3.3 simulators, but when I use the BlackBerry nature in Eclipse to send the app to a BlackBerry playbook simulator, funny things happen. As I click on the buttons they go invisible, but other buttons change too.
Buttons that were only ever visible, stay visible. Some Buttons that were invisible, become visible. Some buttons that had become visible earlier, return to being invisible.
It feels like a redraw problem, or some strange caching on the button state.
Anybody got any ideas? Wild guess excepted ...
Get a playbook or wait until RIM updates their broken simulator.
I converted an app for the playbook and the code was running fine on the simulator. It's a very simple app too, like a binary calculator. A couple of toggleButtons, Buttons and a TextView.
The app had visual issues, similar to yours. Buttons disappeared. Buttons were highlighted when I pressed buttons around them. ToggleButtons didn't change state. And much much more.
Since I don't have a playbook I couldn't test it on a real device. I tried layout changes, code changes and tried different settings. But nothing helped, those issues stayed.
After some reading in their forum I came to the conclusion that this might be an issue with the simulator.
So I submitted the app to the AppWorld 5 days ago. It got approved today.
So there is a chance that your app is alright, and the problem is the simulator.
