Android Question A new installation with errors

[acorrias]

Hi
I need some help. I got a new personal computer with win 8.1 (my previous one was based on win xp)

I reinstalled b4A after the install of java (\jdk1.8.0_66) and android sdk (\android-23). I'm getting errors trying to compile previous app that worked well under windows xp and my previuos setup.
Consider that I copied previous library content in the new one, in order to have b4a working well with all libraries I used previously.

I get this error:

4 errors; aborting

I considered the advice to install android under a folder whose path hasn't space in the string name (since I read something in the forum). So I installed java, android sdk and b4a under c:\programmi (the italian name of program name folder).
But I'm not sure that c:\programmi, as appears from Windows 8.1 gui, is the syntax renaming of an internal folder called "program files" (as realized from some debug activity); in this manner the errors are dued to the space in the folder name, I suppose.

But I need to be sure that the only workaround is to install b4a and android in a c:\new_dir folder.
Please could you give me some advices in order to let b4a work? I wish to use standard Windows folder, but if necessary I could install android and b4a in a different folder under root c:

Please could you advice me also about java installation folder? Is also necessary to install java in a folder without spaces? I want to avoid that other apps using java could not find it.

So , do you think that the errors come from space in folder path or there is some evidence of a different reason?

thanks in advance for the coming help and advices.

I had a similar problem. Check the ini file located in C:\Users\{your username}\AppData\Roaming\Anywhere Software\Basic4android\b4xV5.ini and make sure the MaxRamForDex settings (about half way down the file) is at least 1024. That's what I had to set to get my projects to (re)compile. You may need to increase this value based on the size of your projects.

and you can look here, the same poblem descibed, solution like Indy pointed out...https://www.b4x.com/android/forum/threads/compilation-error.42588/

Hi
I verified MaxRamForDex with the previous installed b5a v5 (5.2) on winxp and it was 512. I have just verified new installed b5a (v. 5.5.0.1) and it is 1024.

I will try to increase it even if the project is the same.
bye Alex

 

[acorrias]

Sorry
but I have increased MaxRamForDex to 2048 and B4a doesnt' compile
Next I have increaset MaxRamForDex t 4096 and it is the same (no compile)

Any suggestion?

 

[Indy]

Having looked at your error messages I noticed that you have a Null Pointer error. I think you need to re-check your code as there maybe be a bug in your code. Best way I always find is to comment out all but the basic code and see how things work. Then gradually bring other code back in and compile. I know this sort of things shouldn't happen after a simple Windows upgrade but, that's app development for you - you only have to change one things and things start to fail unexpectedily.

Sorry I can't be of more help.

Good luck.

 

[Erel]

It is not related to a bug in your code.

Does it happen with all your projects? Try to create a new project and compile it.

Hi all
after a few months without using B4A I decided to verify errors received with the compiling of an app. I got them again.
So I decided to uninstall jdk and android sdk. This to install android sdk in a new directory without space in the filename (as someone suggested).

So I created a directory called java, under c:\. (You could see the ini file at the end of this post.

I uninstalled also java and install again jdk.
So I started with some of previous complied app and I got the same errors. this is the log

please could give me a suggestion about how to solve this problem?
thanks in advance

 

[Erel]

Do you get this error with all your apps?

 

[acorrias]

Hi Erel.
yes I get the error with every app. I tried with previous correctly tested apps. Then, in order to avoid lib with conflicts, I tested with the simplest app
Sub Activity_Create(FirstTime As Boolean)
Log("ciao")
Msgbox("Ciao","aa")
End Sub.
Consider that I installed b4a in a new personal computer and I copyed all libs onto the file system.

 

[Pendrush]

Do not set MaxRamForDex over 1024 if you use JDK x86 (32bit). With 32bit Java I'm unable to compile anything if MaxRamForDex is set over 1024.
I'm using Win10 x64 with JDK x64. MaxRamForDex = 4096, my computer have 8GB ram and I don't have any problem compiling extreme large projects.
You can try to download JDK x64, and set MaxRamForDex for example to 3072 or above. Also, you need to change javac.exe (to JDK x64) path inside B4A.

 

[acorrias]

Hi
I installed 64bit version and I also used MaxRamForDex = 4096. But anyway. I get again the error

I installed
jdk-8u74-windows-x64.exe

 

[acorrias]

Hi all.
I removed b4a and reinstalled it. with the new release
I did a clean install removing any previous file.
I got no errors.
My problems now is that I have to recycle libraries and that I don't know if some one generates some conflict.

Any suggestion?

HI all. I have moved all the libs in lIbraries folder without update the new installed with the last version of B4A.
Now it is all ok
