Thanks I've tried most of those but will try points 2 and 3 and report back soon

Same here:

Galaxy Tab 4 + Admob Banner ads + Crosswalk = Crash

Frame rate drops from 57 - 60 to around 30 fps

Remove banner ads (cranberry) and app runs at full pelt.

Does this happen on other apps too?

I had a similar problem on my S3. Took ages to figure out what it was.

Turned out I had removed the memory card from my S2, put it straight into my S3 and there was some corrupt files on the memory card.

Reformatted the memory card inside my S3 and the problem disappeared. Phone was a lot quicker too.

Not sure why this worked but maybe worth a try. Backup your data on the card first of course.

Might it be an idea if SCIRRA, a Mod or User set up a Google group so that other construct users can be added as testers.

We could all then test each others apps in Beta and Alpha mode.

Would be a help to test our apps on as many devices as possible before launch.

Or maybe such thing already exists?

When you export from Construct 2 select Hide Status Bar

In Intel XDK click Projects (top left) and then Build Settings [+] and tick Fullscreen

On the Intel XDK emulator there is also a checkbox (on the right) which lets you show/hide the status bar

I normally ignore row zero in my levels array

My 100 level array is 100,5,1

Basically just X,Y no Z

key - val1, val2, val3, val4, val5

You could do 50,6,1

Key - lvl1, score1, lvl2, score2, lvl3, score3

OR

Key - lvl1, lvl2, LVL4, score1, score2 score3

++++++++++++++++++++++++++++++++++++

Example

Lookup scores of level 25

Array Layout = Key - lvl1, score1, lvl2, score2, lvl3, score3

Key 25 - Level 1 and Score = 0,0 and 0,1

Key 25 - Level 2 and Score = 0,2 and 0,3

Key 25 - Level 3 and Score = 0,4 and 0,5

However, I would store the score separate from the Level array

Lookup Level array and then lookup Scores array to get values

If you put scores in the same array as the levels and then update the game (adding more levels) people could lose their progress

Turned off all banner and inter ads and now it doesn't crash.

For reference:

Unbounded scrolling: Yes

Fullscreen in browser: Scale outer

Fullscreen scaling: High Quality

Use high DPI display: Yes

Orientation: Portrait

Enable WebGL: On

Sampling: Linear

Downscaling: Medium quality

INTEL XDK

Crosswalk version 11

Cranberry admob plugin

Left Cranberry admob plugin in build (just in case I use in later)

Deleted all references to admob within app (no calls)

Exported app now runs without crashes

With admob test ads set at image only was getting less than 30 fps

Without admob getting between 50 and 60 fps

Layout size 768 x1366

Window size 768 x 1024

Very frustrating day

Thanks, no just the one app is causing problems.

Fan keeps kicking in though

Actually just realised that my computer has restarted 3 times when running the app preview in Chrome.

That's a complete shut down and restart.

Very strange behaviour.

Is there a way to track app crashes on device?

I have an app that I'm testing. Usual story. Runs fine locally, but crashes on an Android device.

Seems to be ok on Samsung S3, but lasts 5 minutes on my Galaxy Tab 4. No error, simply quits.

Runs fine in Intel XDK emulator and on the debugger.

Timed it and it crashes nearly exactly every 5 minutes after launch, which is strange as there is no function that is called every 5 minutes.

No error is reported on crash. So is there a log file stored on the device that I can access or is there an app which can log the error?

Wicked

Thanks for that and have a great weekend.

I currently use

Every tick

Set angle to angle + RAINBOWSPEED

But of course the speed this happens varies due to fps

Is there a better way to rotate the object that is independent of fps?
