Re: [android-developers] Re: Should SQLiteDatabases be limited to 2Gig?
From my guess the database gets corrupted because of (some) flash disk controllers that lie to the OS and do not flush/sync properly the FS before crash/reboot, so even with transactions the DB gets corrupted in some cases. Le vendredi 20 septembre 2013 02:34:51 UTC+2, Kostya Vasilyev a écrit : Yes, but if the database can't be opened at sqlite level, it would only help the app know that, not recover the data... And there are other ways to detect that. Back to square one: why do they get corrupted in the first place?

I am seeing behavior that appears to indicate this may not the case. Is there anything I can do to ensure other processes are not using more than 10% of CPU (or any number really)?

[android-developers] Accelerated HTML Rendering issue (relative vs absolute position)
Hi, Using a Webview to render content, I noticed that Hardware Acceleration (ICS) triggers rendering issues when HTML elements are using absolute positions, relative positions are fine. Is it normal or know Webkit behaviour ? I would have thought WebKit's HTML parser would parse, and calculate positions, and layers independent of any hardware acceleration. Then by the time any HW acceleration code is involved, that code would be dealing with absolute coordinates, layers, sizes, etc. Perhaps not.

[android-developers] Re: GPU Acceleration - still not worth using on 4.1.1?
Is anyone else seeing as much weirdness with GPU accel as I am? I do see troubles too with GPU, especially this one: ICS WebView blinks when Hardware Acceleration is used http://code.google.com/p/android/issues/detail?id=25722 , very annoying as no HW acceleration = no HTML5 video tag working. Seems you mentionned the Webview blink is fixed in 4.1.1, but the bug report looks it's not, could you confirm ? Le mardi 16 octobre 2012 19:00:48 UTC+2, Kostya Vasilyev a écrit : I'm seeing strange issues with GPU acceleration in my app. First, on 4.0.3 / 4.0.4, a WebView with a dark background color flashes white whenever I reload its data. It does this over the whole screen, which looks really nasty in a multi-panel (fragment) UI. This is on an Asus TF101, Sonty Tablet S, Acer A100 -- all Tegra 2 devices. Ok, so I turn off hardwareAccelerated in the manifest for API 16. Now, if the user forces GPU acceleration on, on some devices, with some content, WebView displays nothing, staying blank. Disabling force GPU in the device's settings magically makes everything work again. I've seen the advice to check if GPU is forced, and showing a warning message, but since the issue only happens occasionally, I'm not sure if it's worth it to irritate those who have force GPU on without bad consequences. This is WebView, it's not even my code (which is of course buggy and a crappy), but this is part of Android. I've not seen this failure on my devices, identical to those of users who'd run into this. Enter Android 4.1.1. Ok, the WebView background flash is fixed, so I enable hardwareAccelerated in the manifest as a conditional boolean just for API 16 and higher. New issue: I have an activity with an EditText, whose content I set from code (a message draft) and sometimes append to (a signature). The appended text sometimes renders on top of the other text, making a big mess. Ok, fine, I force a software layer on this EditText. This resolves the text overlap issue, but now some content appears to render white on white: the view scrolls as much as it's supposed to, shows the glowing overscroll indicators, but there is nothing to see. If I turn hardwareAccelerated off in the manifest or remove setLayerType(SOFTWARE), the same content (and I mean the same content, it's loaded from a database, and it's deterministic) renders just fine. So here what I'm trying to understand: - Is anyone else seeing as much weirdness with GPU accel as I am? - Am I just so special hitting one bug after another? - Is GPU acceleration, by and large, unexpectedly broken and randomly unusable, even in 4.1.1 on the Galaxy Nexus? - Do I have better things to do than chase one Android bug after another?

(tested on: SGS2, HTC Desire, LG L7, Ainovo Paladium tablet, all running 4.0.x) I've already tried changing the manifest to android:hardwareAccelerated=false and also set the VideoView layer type to mVideoView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); The code itself is very basic and just using the standard video view and media controller: setContentView(R.layout.act_video_player); mVideoView = (VideoView) findViewById(R.id.vw_player); mVideoView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); MediaController mc = new MediaController(this); mVideoView.setMediaController(mc); Uri uri = Uri.parse(mVideoURI); mVideoView.setVideoURI(uri); mVideoView.requestFocus(); and the manifest: uses-sdk android:minSdkVersion=7 android:targetSdkVersion=15/ supports-screens android:largeScreens=true android:normalScreens=true android:smallScreens=false android:resizeable=true android:anyDensity=true/ application ... android:hardwareAccelerated=false/ Below is the complete log, of which I think the following lines are relevant: W/QCvdec ( 2751): get_config: unknown param 117440527 I/OMXCodec( 2751): [OMX.qcom.7x30.video.decoder.mpeg4] video dimensions are 960 x 560 W/QCvdec ( 2751): get_extension_index: Error, Not implemented E/OMXNodeInstance( 2751): OMX_GetExtensionIndex failed Anybody else having experienced issues with video playback on ICS?

[android-developers] Re: Why would SIGSEGV crash occur in Galaxy S3 Android WebView?
Try HW acceleration ON or OFF, ICS Webview has troubles with some CSS/CSS3
+ HW acceleration. Also try to lower android:targetSdkVersion to 11 for
example.

I have a complex, interactive HTML5 in an Android WebView - and it works
fine on basically all platforms except Galaxy S3. On Galaxy S3 (Android
4.0.4), once out of every 5 times or so, just after the load completes,
/system/lib/libwebcore.so tries to access invalid memory and a Fatal signal
11 (SIGSEGV) at [various addresses] (code=1) is thrown.
The HTML5 is a tiny battle where enemies appear and the user slashes them
to proceed. In between battles are normal html pages: normal page - HTML5
battle - normal page - HTML5 battle - normal page - HTML5 battle. The
HTML5 doesn't do anything particularly out-of-the-box - there's a lot of
-webkit-animation calls...
.enemy {
position:absolute;
opacity:0;
-webkit-animation:enemyAnim 0.6s linear 0.2s;
}
…that reference a lot of -webkit-keyframes...
@-webkit-keyframes enemyAnim {
from {
-webkit-transform: matrix(1, 0, 0, 1, 144.25, 150.25) scale(1, 1);
opacity:1;
}
8.33% {
-webkit-transform: matrix(1, 0, 0, 1, 189.406, 102.206) scale(1.3066,
1.3066);
opacity:1;
}
16.66% {
-webkit-transform: matrix(1, 0, 0, 1, 200.424, 82.649) scale(1.414,
1.414);
opacity:1;
}
/*…*/
And a fairly complex div tree, but nothing particularly experimental.
There's some level of Javascript, but the hangs appear to occur even with
all Javascript turned off.
Has anyone ever had a problem with a Galaxy S3 being…different? No
Android 2.x devices have this problem, and even a Galaxy Nexus running
4.1.1 doesn't seem to have any particular problem. I've never been tempted
to write to Stack Overflow before, but this is really vexing me...
Searching on Android WebView sigsegv crash 4.0.4 WebView sigsegv
crash gives several issues, but:
- webview.clearCache()/webView.destroyDrawingCache() don't seem to have an
effect (though this hang is clearly a memory issue, adding/removing
System.gc()s in various places had no great result)

http://code.google.com/p/android/issues/detail?id=16563
- I looked at the changelist for android webkit looking for suspicious
fixes after 4.0.4, and thought I had something with the below, but rooting
the S3 and taking it to 4.1.1 didn't fix the issue:
https://github.com/teamgummy/android_external_webkit/commit/61e0d189f2b74650bf72a6a2820f66a8b17c3d06
Since some of the crashes are occuring during memory free()s, I know that
things are being free'd around the time of the crash and my gut feeling is
that some things are being freed mid-render that shouldn't be. It's
frustrating because SIGSEGVs should be physically impossible with pure
HTML, JS, CSS =/
Below is a sample crash report. Note that the crash location is not
limited to the below; crash reports don't seem to be wildly different but
there seems to be some variation in location.
