listactivity is stuttering caused by WindowManager - android

i have a question regarding some weird logcat outputs.
Scenario:
I have a listactivity with images and textviews, etc. The images are loaded by Fedor's implementation of LazyList. I changed his cache to a LRUMap from commons.
On scrolling i got sometimes a stuttering and logcats shows me a lot of this messages:
V/WindowManager( 2482): Dsptch > Window{48267640 <packagename to Listactivity> paused=false}
V/InputDevice( 2482): ID[0]=0(0) Up(1=>0)
Any ideas what these messages mean?
Thx in advance

MediaCodec.createInputSurface() throws IllegalStateException on some devices

I'm working on a video processing app. The app has one Activity that contains a Fragment. The Fragment in turn contains a VideoSurfaceView derived from GLSurfaceView for me to show the preview of the video with effect (using OpenGL) to users. After previewing, users can start processing the video.
To process the video, I mainly apply the method described in here.
Everything works fine on most devices, but the Oppo Mirror 3 (Android 4.4). On this device, everytime I try to create an Surface using MediaCodec.createInputSurface(), it throws out java.lang.IllegalStateException with code -38.
E/OMXMaster: A component of name 'OMX.qcom.audio.decoder.aac' already exists, ignoring this one.
E/SoftAVCEncoder: internalSetParameter: StoreMetadataInBuffersParams.nPortIndex not zero!

Playing around a little bit, I observed that:
BEFORE creating and adding the VideoSurfaceView to the layout, I can create MediaCodec encoder and obtain the input surface successfully. And I can create as many as I want if I release the previous MediaCodec before creating a new one, otherwise I can only obtain one and only one input surface regardless how many MediaCodec I have.
AFTER creating and adding the VideoSurfaceView to the layout, there is no chance that I can get the input surface from the MediaCodec, it thows java.lang.IllegalStateException always.
I've tried removing the VideoSurfaceView from the layout, set it to null, before creating the surface, but no luck for me.
I also tried with suggestions from here, or here, but they didn't help.
From this, it seems that my device can only get the software codec. So that I cant create the input surface.
My question is:
Why was that?
If the device's resources is limited, what can I do (release something for example) to continue the process?
If it is related to the software codec, what should I do? How can I detect and release the resource?
Is this related to GL contexts? If yes, what should I do? Should I manage the contexts my self?

Android app crashes with WIN DEATH after memory-intensive activity

Summary
I work on an Android app which, as one of its features, involves users marking up an image and saving it. This process involves some heavy canvas drawImage() calls (sometimes on an image around 12 MB+ uncompressed) as well as lots of encoding and decoding of data. The image data also cached in the Android file system and passed from Java to JavaScript through a JavaScriptInterface.
However, with an LG G Pad X8.3 running Android 5.0.2, we are getting lots of crashing. When it crashes, the log says "WIN DEATH" and it goes back to the home screen without showing any "Unfortunately, ___ has stopped" message. Our "WIN DEATH" is preceded by a win death of the InputMethod and before that a "WIN DEATH" of com.lge.launcher2.Launcher. It is intermittent, but frequent enough to be a big problem.
Details
(1) It seems to happen after the heavy image saving manipulation, but not immediately after
(2) It happens more often when the keyboard is brought up. Is something about bringing up the keyboard causing it to crash?
(3) When watching the memory usage in Android Studio as the app is running, nothing is too out of the ordinary. When it crashes, there is still free memory available in the graph.
(3) We tried using largeHeap in our manifest, but that did not eliminate the crashing.
(4) Memory usage is between 10 and 20 MB.
(5) I can add around 32 million numbers to a JavaScript array before the web view crashes. That's at least 240 MB (8 bytes per JS number). When it crashes, it shows a blank screen, as opposed to the crash I am trying to fix where it brings you back to the home screen.
(6) There is a well publicized memory leak (or a couple, actually) in this version of Android, but LG does not offer upgrades for this model.
(7) We have tried optimizing the code to use as little memory as possible, but the crashing remains.
(8) The crash logs always contain similar information around the crash.

The memory leak that may be partially responsible: https://code.google.com/p/android/issues/detail?id=79729
Question
What could be causing the app to crash in this way? Is it a memory issue? is anything in the log output that I've copied here relevant?
Has anyone else had this problem and solved it? Is the Android 5.0.x/1.x memory leak bug responsible?
I wish I could be more specific, but the code is proprietary and the problem isn't (or hasn't yet been) localized to any one particular code sample. If more information is needed about a particular issue, please ask.
Update
I've noticed that there are a bunch of Choreographer messages in the logs about it doing too much work, but they are relatively small frame skips (~ 35 frames) and the last message occurs a full 20 seconds before the app crashed.
Update 2-10-16
We are now trying to reuse canvas objects in case they are not garbage collected, and we are also calling System.gc() when onTrimMemory is called with TRIM_MEMORY_RUNNING_LOW. This seems to have reduced the crashing to some degree, but still frequently enough to be concerning. Most of all, I would like to understand why it seems to randomly use up too much memory and crash. I've added the onTrimMemory lines to the log output below, which show it going from low to critical in a span of 100 ms. If this only happened when actually performing the memory-intensive actions, that would make sense, but it happens sometimes long after the user process has finished.
Pulling my hair out over here, trying to get a HTML Canvas based application running in CrossWalk on a Fire TV Stick. The app would run fine then crash after 30 minutes of use with this error. I was able to fix it but my use case is pretty specific, either way it may help folks who show up here later.
TL;DR: Reduce the size of textures being loaded into and out of the GPU.
I had a fullscreen canvas element running PixiJS, working essentially as a slideshow. The problem came from a single slide type, where large images with transparency would animate over a fixed background. After logging the CPU/GPU usage in Chrome's timeline feature I could see that the textures were being loaded into and out of the GPU all the time to accomplish the affect. Ultimately, I was able to resolve the issue by completely removing the background image element from canvas, and just displaying it in a div behind the canvas. The affect was identical, but the performance was improved significantly and this problem disappeared afterwards.
You are dealing with large bitmaps and loading all of them at run
time. You have to deal very carefully with large bitmaps by loading
the size that you need not the whole bitmap at once and then do
scaling.
Huge JavaScript Cause This
Given that you are working with limited memory, ideally you only want to load a lower resolution version in memory. The lower resolution version should match the size of the UI component that displays it. An image with a higher resolution does not provide any visible benefit, but still takes up precious memory and incurs additional performance overhead due to additional on the fly scaling.
Please check Managing Bitmap Memory.
You are using lots of canvas at once that's why this problem .
This used to happen with me, even after i used the large heap attribute in application manifest and it stopped to happen when i reset all the variable to null after finishing using them.
I don`t know your code but i would advise you to re-use the same variables and make sure you clean up after every operation and when done, because keeping in the memory large unused files is not good.

Phonegap Android App Not scrolling pages

I am developing a phonegap based android app by using jquery mobile, but pages in my application are not scrolling and on touch events, I am getting these messages in android logcat -
12-26 11:37:50.023: WARN/webview(11326): Miss a drag as we are waiting for WebCore's response for touch down.

also,(it might be helpful) I am using photoswipe.js for touch based image gallery. Can somebody tell what might be the reason for pages not scrolling.
I found the answer, it might be helpful for other people. the issue was that one of my html pages had one iframe showing youtube video content,apparently android(particularly versions before android 3 dont like iframes). Fixed it by removing the iframe.

Android Canvas OpenGL Renderer is out of memory

I develop android library for drawing chart at view, using canvas.
However, the following errors occur frequently.
LogCat:
D/NvOsDebugPrintf(11526): NvRmChannelSubmit: NvError_IoctlFailed with error code 12
D/NvOsDebugPrintf(11526): NvRmChannelSubmit failed (err = 196623, SyncPointValue = 94008102)
(87 times repeat)
D/OpenGLRenderer(11526): GL error from OpenGLRenderer: 0x505
E/OpenGLRenderer(11526): OpenGLRenderer is out of memory!
Solution is not found although I am groping for various causes and solution.
So, please tell me about what can become a cause which such an error generates?
And how can solve this problem.
I beg your kindness. Finally my sincere apologies for my poor English.

How to improve memory usage with BitmapFactory.decodebyteArray()?

In a thread i'm fetching a jpg image (from a socket) and putting it in a byte array datas[].
Then i make a bitmap and send it to my ui to display it in an imageview :
Thread side :
bundle.putParcelable("image", BitmapFactory.decodeByteArray(this.datas, 0, jpgSize,this.bitmapOption));
message.what = ThreadMessages.MSG_IMAGE_AVAILABLE;
message.setData(bundle);
this.uiHandler.sendMessage(message);
The bitmap option is defined as following :
this.bitmapOption = new BitmapFactory.Options();
this.bitmapOption.inPurgeable = true;
ui side :
cameraView.setImageBitmap((Bitmap) bundle.getParcelable("image"));
As far i know it's works fine on phone with android 2.x and 4.0.x. But i have made some test with a galaxyTab 8.9 (android 3.1) and my activitie is killed by the system due to a high memory usage :
01-30 14:12:02.311: I/ActivityManager(72): Process my.package (pid 1175) has died.

01-30 14:12:02.391: I/WindowManager(72): WINDOW DIED Window{410f5020 my.package/my.package.main paused=false}
The fetched bitmap is not a very high res pictures (800*600 max) but it is displayed at least at 10 fps (more if it's possible).
Using the inPurgeable option lets me avoid the OOM crash (i had it before using inPurgeable) but it not seem to be enough .
Using inSampleSize (like explained in Strange out of memory issues) don't seems to be a solution because it resize the image, and i need a image which take the entire space of the imageview.
How can i improve my memory usage knowing that i'm receiving a jpg in a byte array and i need to display it in a imageview ?
Note : i don't need/want to resize the bitmap, the received jpg is already well sized.
Note 2 : Triggering system.gc() after each decodeByteArray seems to solve th eproblem, but it's ugly and performance are slowing down drasticly
Using Parcelable to send large amounts of data in Intents is a bad idea and is likely to result in poor performance. You would be better to store the image to persistent storage, and pass a URI to the stored image instead of the image data itself.
There is some more info on this in how do you pass images (bitmaps) between android activities using bundles?
There is no need to use a Bundle if you're only passing the Message within your application process. Simply pass your Bitmap in Message.obj.
