Text setText isn working

[Nortsx]

When i call the method setText of the Text class it crashes the application. Tested on Desire.

This is very unlikely to be a bug, a lot of people use setText with GLES2 on desires without issue - it is almost certainly something to do with the manner you're calling setText.

Hmmm...ok let s try to understand my fault. Now i ll show the code.
I have a class which realises scrolling, and i want to watch debug information without touching the debugger.

what s wrong with it? Maybe this method called in separate thread which doesn t have any access to public fields of my main activity class, but it looks like kinda delirium=))

I'm pretty sure you need to use the:

constructor variant. Note the pCharactersMaximum - this is the maximum chars the text can grow to.

[Nortsx]

Huh it solved the half of a problem. Now it works but only for the first time. When i scroll it the second time instead of placing some figures into a text it crashes. Looks like stack overflowed somwhere?

[OzLark]

The rest of that code looks fine, the stack trace is your friend.

[Nortsx]

Can you show the example of text changing in your code? I tried the Nicolas`s example with textchanging but it also crashed. I guess it s a bug anyway)

[Nortsx]

That s an issue.
Two examples
WORKS FINE.

If i put the figures in constructor it works OK. What s the problem with that?

If i put the figures in constructor it works OK. What s the problem with that?

The only thing that stands out to me is that "MONEY" is 5 chars long and "MONEY 500" is 9, does the constructor call specify at least 9 characters for pCharactersMaximum?

There is my constructor.

1. capitalText = new Text(100,100,this.mMainFont,"Capital:",500,this.getVertexBufferObjectManager(),DrawType.DYNAMIC);

Parsed in 0.035 seconds, using GeSHi 1.0.8.4

It looks like anything that is longer than start string`s length doesn t go into the buffer and crashes somehow(with max length and DrawType.DYNAMIC applicatoion doesnt crash but i have the black screen).
