Program Crashes #290

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Open document
2. Pinch-zoom/unzoom same page repeatedly (3-4 times)

What is the expected output?
I would expect to see the same portion of the page zoomed in and zoomed out, 
possibly faster after the first cycle due to bitmap caching.

What do you see instead?
After three to four repetitions, the viewer crashes silently and returns to the 
Browser or Library Activity. Sometimes, I get an ANR or FC.

Currently, I get the crash on the first zoom-out.

What version of the product are you using?
1.5.0 downloaded here

On what operating system?
Android (Kindle Fire) 2.3.4

What device are you using?
Amazon Kindle Fire

Please provide any additional information below.
The zoom performance of this latest version is very disappointing, as noted in 
another issue. Us users of multi-core devices (dual-core and quad-core) were 
expecting more. 
It would be EXTREMELY helpful to have a wiki page addressing the various 
performance settings, so we can make informed changes to them, rather than 
guessing what they might do.

I plugged the device to my ADB console and got the log above. It now crashes 
almost immediately when revisiting a recent book which has a high zoom level, 
making the app entirely unusable.

how many pages kept in memory?
is bitmap reusing is switched on?
is bitmap allocation hack is switched on?
is using native graphics is switched on?

how many memory does your device provide for application heap? pls provide 
application info which written in log when application is started.

Also, it crashes on Google Nexus 7, but not nearly as quickly.

Android 2.3.4 does not allow to use large heap. Upgrade your device to android 
4.0.3 or 4.1

That's really not an option. However, if your software reliably and repeatably 
crashes in android 2.3.4 and earlier, you need to modify your manifest to 
exclude those targets. Otherwise folks will keep downloading it from the Play 
Store and leave negative feedback. The cleaner alternative would be to clean up 
memory management to support devices with smaller heap, wouldn't it?

That said, the app also crashes on Google Nexus 7, which runs Jelly Bean, with 
very similar logs.

"However, if your software reliably and repeatably crashes in android 2.3.4 and

I beg to differ. Crashing could due to the particular hw or sw configuration 
you are using. I am using Android 2.3.1 and I don't have that problem at all. 
I would mind if ebookdroid was pulled from the market for my device.

My performance setting:
pages in memory 0
bitmap reusing yes
bitmap allocation hack NO
native graphics yes

@peltio - The developer has already pinpointed the problem to Android 2.3.4 
when he said "Android 2.3.4 does not allow to use large heap. Upgrade your 
device to android 4.0.3 or 4.1".

If that were true, then he would indeed need to exclude those target -- but I 
don't think the reason he gave is accurate, thus my statement. I have also 
further identified that the app crashes on Nexus 7, which runs Android 4.1.

The real question remains as to what we can do to help the developer 
trouble-shoot the issue and hopefully fix it. eBookDroid could be a great app 
and reach millions of users on Kindle Fire if only it worked.

Main problem in debugging such issues is that we do not have hardware to 
reproduce and test. Emulator != real device with the same OS version.

All rendering and memory allocation code were rewritten. Bug is not actual.
