JackcessDemo (problem)

[ciginfo]

Hello
Why this message when I run JackcessDemo?
Northwind.mdb is really in Jackcess\Files
Thank you

 

[ciginfo]

If I work on other PC, there is an other problem with JackcessDemo, while it works very well with other applications.

Signing package file (private key) 1.10
ZipAlign file. 0.04
Installing file to device. Error
pkg: /data/local/tmp/JackcessDemo.apk
Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE]

Restarting ADB Server may solve this problem.
Tools - Restart ADB Server. Device serial: emulator-5554

Restarting ADB Server is not effective
I don't understand. If you have an idea?
Thank you

Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE]

It seems to be telling you that you have run out of space on the device.

 

[ciginfo]

1°) You think "Northwind.mdb" is too heavy? How can increase the storage capacity?

2°) And what means the error message on the first PC?

1°) You think "Northwind.mdb" is too heavy? How can increase the storage capacity?

No, that means you cannot install the application because there's not enough room on your device. Try to remove a few unused apps.

Excuse me to return to the subject, but it is still impossible to run properly "JackcessDemo". Here the error messages. Can you run this demo?

[agraham]

That's not an error message. It looks like the debugger has paused the app.

Bonjour ciginfo:
Maybe the device you have does not have or does not support external sd card (it does not have to be a proper external card). Change the code to:
File. DirDefaultExternal instead of File.DirRootExternal and see what happens.

 

[ciginfo]

No, it is the same thing with DirDefaultExternal. I don't understand. But have you tried JackcessDemo on your computer?http://www.b4x.com/android/files/Jackcess.zip

 

[agraham]

Always always, when there is a problem look in the Logs!

 

[ciginfo]

Here the logs but I don't understand always.

It's odd that there is no message associated with the IOException. You could try two things.

1) Catch the Exception with Try..Catch and see if LastException.Message returns any useful information. I guess it may be blank which is not helpful.

2) Avoid this step altogether, remove northwind.mdb from Files and manually put it on the device removing the first line of Activity_Resume.

 

[ciginfo]

Thank you for your answer. I use virtual device on the computer created with AVD Manger in the SDK and I don't know how to put Northwind.MDB directly in the virtual device .

 

[agraham]

Find and run ddms.bat in your Android SDK installation. Select the emulator in the top pane left and then select Device -> File Explorer. That will let you transfer files to and from the PC.

 

[ciginfo]

No, it is the same thing. I have put Northwind.mdb on the virtual device into the file "data", I have deleted the first line in activity Resume, I've tried to change DirRootExternal into DirDefaultExternal, always the same thing

 

[agraham]

The correct path for File.DirRootExternal is probably /mnt/sdcard, at least it is on my emulator instance.

 

[ciginfo]

OK, now it runs fine. Thank you for all the time you spent on my problem.
1°) Do you think it will be the same problem if I use another base.mdb?
2°) Do you think it will be the same problem also if I use a real device?
3°) In my application I have to download a "Base.mdb" (because varies daily) at opening tne appli before running the appli.
What is the line of code to download in File.DirRootExternal? Then I think that on a real device, first line "File.Copy (File.DirAssets," Data.mdb "File.DirRootExternal," Data.mdb ")" must be kept and will run fine, or have I also to change this line ?
Thank you again, I hope not disturb you more.

 

[agraham]

1) I've no idea.

2) I've no idea.

3) I can't design your application for you, but if you are downloading a new file, presumably from the Internet or over a network, then copying a database from File.DirAssets is irrelevant.

 

[ciginfo]

OK, thank you very much.
