Android Question I'm Stuck! DirInternal Working on Phone, Not Tablet

[Shadow&Max]

Please note: I've since discovered that it's not the DirInternal issue that's causing this, but instead, accessing the layout files after installation on the tablet. See below for the error log etc.

I'm really stuck. I'm using Erel's KeyValueStore class for a small, persistent database. For two months I've been developing this app and am getting ready to send it out to testers. Up until now, I've been using emulators (Genymotion & AVD stuff) as well as my Moto-X phone, and everything was working properly.

I purchased a cheapie tablet to test, just to be sure, and it's not working at all. The Phone doesn't have an SD card, and neither of course do the emulators.

When I run this on the tablet, which DOES have an SD card, the app immediately dies as I'm calling the KeyValueStore with File.DirInternal in one of the first steps. (After further investigation, it's not that call to DirInternal that's failing, but instead trying to open the bal files)

On the tablet, it's erroring out on the open, saying it cannot find the file on the SD card. I'm not trying to use the SD card. I want to avoid the SD card cause it could be removed and then my data is gone.

Am I accessing the wrong dir??? I only access two in the entire app... File.DirAssets for the icons etc., and File.DirInternal for everything else.

How can I get past this? Until I solve this, I can't release this app, and I really NEED to release this app.

Any help would be appreciated.

Do you have the stacktrace of the crash?

java.lang.RuntimeException: java.io.FileNotFoundException: /mnt/sdcard/Android/data/com.twodogapps.gaa/files/virtual_assets/about.bal: open failed: ENOENT (No such file or directory) at anywheresoftware.b4a.shell.Shell.virtualAssets(Shell.java:159)

It appears it's trying to open the layout file for the about screen, and I'm not assigning anything unusual to that.

FYI, I uninstalled the app from the tablet first, and did a new install of the app in debug mode... it never opened but just immediately stopped...

It looks like it's B4A and not my data file it's trying to access...

Also, before I deleted the app from the tablet, I checked the data usage and there was none on the SD card at all for the app... I can't tell on the Moto-X because there's no SD card ability.

[eps]

What are the Android Versions of the two devices?

 

[Shadow&Max]

4.1 on the tablet, kitkat on the phone, and the emulators are various versions...

 

[eps]

Actually Android version isn't the issue here.

What is the code that is failing? Of course DirInternal isn't actually an Internal Directory as such, so could be placed on the SD card.

 

[eps]

Have you changed the BAL file names at all? as per http://www.b4x.com/android/forum/th...he-new-bal-name-by-default.30908/#post-179916 but then again you're not getting a compiler error are you?

 

[Shadow&Max]

I fails immediately... no code... it's trying to find the layout files.

No, haven't changed ANY names. About.bal is a simple form that I created in the initial stages of this app 2+ months ago.

 

[eps]

or changed their location?

 

[eps]

B4A version?

 

[Shadow&Max]

Nope...

 

[Shadow&Max]

3.50

 

[eps]

You haven't removed that file have you? Something else would seem to be the problem here.

 

[eps]

If you look in the IDE at Files does it show your BAL file?

 

[Shadow&Max]

No... the app runs perfectly on the phone and emulators... dies on the tablet... something obviously to do with how the files are copied during installation.

Yes, they're all there in the IDE...

 

[eps]

So no name changes or anything along those lines..? Maybe the phone has an old version of a file on there or something.. Is the set to use External Memory? or something...? I think I had an issue once with an App which got confused, it was installed to use Internal Memory only (standard) then changed to use External Memory and then it threw a wobbler as it still found some of the older files and complained.

If you attempt to open the BAL file within B4A what happens?

 

[margret]

This may not be it, but some devices I've used didn't care and others did. All the names of bal files and any other files in the Files folder should be in all lowercase.

 

[Shadow&Max]

I'm going to try that now Margaret. All of mine are in upper and lower case. I'll rename about and see if it skips that and goes on to the next...

 

[eps]

Well it's complaining about "about.bal" so this is probably the issue here, a good call from Margret!

 

[thedesolatesoul]

Does it work in Release mode?
