The Android app using OpenCV sometimes crashes. Is it because memory is used too much?

[Linda Li]

I developed one Android app using OpenCV and tesseract-android.
We press a button to takes one photo (), then binarizes the photo, then output the ocr result.
We could contine to press the button to take another photo, and then go on.
The UI is based on this link "Making an OCR Android App using Tesseract - Gautam Gupta's Blog".

But sometimes after several rounds of photo-binarization-ocr procedure, it crashes. The number of several rounds varies from 1 to about 5.

One snippet of the log information is below:

12-26 01:05:13.562: I/DEBUG(2610): debuggerd: Mar 30 2012 16:30:48

12-26 01:05:18.056: V/StatusBarPolicy(229): cdmaLevel:1;max:6

I assume the app crashes at the point:
12-26 01:05:16.375: V/run::sending to native(666): parameter count[2]

Then what problem happens to crash?
How can I solve it?
I suspect the memory might be used too much and put the app on the verge of crash, since the former version of the app, which uses less memory, does not have crash issue.
But since the app can run successfully for several rounds, that means the memory should be enough. How can I solve it?
Thanks!
