getting SIGNAL 11 error
<p>Good day,</p>

<p>I have a question about developing applications for Android using SDK.
Our app faced an issue under Android 2.1 API Level 7 (at least under Android 2.1-update1 emulator and under Motorola Droid X 2.1 device).
It crashes and emulator shows in logcat only native error info about crash, without any java stack trace etc. After that app is trying to reload itself but crashes again. It works fine under Android 2.2 and 2.3.
Our users have Android 2.1 devices and get that problem.</p>

<p>I tried to find an answer via google search, but did not get any good suggestions. It is very hard to understand what is the real cause of such error. How to debug and resolve that?</p>

<p>Thank you for feedback!
Cheers!</p>
