Android textview stackoverflow when using Hebrew

Question

My app is retrieving data from a RESTful http source.
Sometimes, there will be Hewbrew text.
title קול המדיה, עמוד הבית
content הפיג'מות - עונה 6 פרק 12 עכשיו לצפייה ישירה! קישור: הצג את הדף

Everything is fine until it has to be used in a textview. I'm using my own list adapter and the following happens when this text tries to get loaded:

I/dalvikvm( 2524): Stack overflow, expanding (0x41048200 to 0x41048000)
I/dalvikvm( 2524): Shrank stack (to 0x41048200, curFrame is 0x41049cd8)
D/AndroidRuntime( 2524): Shutting down VM
W/dalvikvm( 2524): threadid=3: thread exiting with uncaught exception (group=0x4000fe70)
E/AndroidRuntime( 2524): Uncaught handler: thread main exiting due to uncaught exception
E/AndroidRuntime( 2524): java.lang.StackOverflowError
E/AndroidRuntime( 2524):        at android.text.Styled.drawText(Styled.java:290)

So, I tried to use a try/catch around the code, but I no help. The catch doesn't catch this exception.

My code:

try{    
   holder.content.setText(currPage.GetContent())      
   holder.title.setText(currPage.GetTitle());      
} catch (StackOverflowError e){      
   e.printStackTrace();  
}

That doesn't work because that's not where the exception is actually happening. It's when the text is being drawn onto the screen. I don't know how to stop this from happening. I really would rather just have a blank field if that is the easiest fix, but I don't know how to detect for Hebrew text is decent way. Any help and suggestions would be greatly appreciated.

Thanks Cheers, Terry.

NOTE: The original post and title said Arabic. It's been correct to say Hebrew. Maybe it matters.

Answer 1

I have written Arabic text to a TextView many times without seeing a stack overflow exception, which is also a Right-to-Left (RTL) language. Did you modify the onDraw() method or any other method that might be causing this error?

If you can't find the reason, this should return true if the given inputText contains Hebrew characters:

Pattern.matches("(\\p{InHebrew})+", inputText);

You might also want to disallow any non-Latin characters if other languages cause problems as well. This site contains a list of all of the unicode scripts you can match against:
