问题
I have made a custom camera in Andorid using Javacv code. I hadn't included all the .so files but only those which seems required for my application. As in the screen shot below:
It works well on Samsumg Galaxy S2, S3 and Sony Ericsson Xperia Arc. No problem at all. But when I tried to run it on Samsung P7500 Galaxy Tab 10.1, it crashed on the very first line of Javacv code I have used which happens to be:
yuvIplImage = IplImage.create(previewWidth, previewHeight, IPL_DEPTH_8U, 2);
Logcat Ouput for this attempt:

My Super Hero "Mr. PID 7847" Died :(
From this log I can easily interpret app is trying to link to libtbb.so But no clue what went wrong.
I attached source code to javacv jar but still no clue. Then I removed the jars and included code in my project with required jars, As you can see in screen shot below:
Using break points I found that app is crashing at
com.googlecode.javacpp.Loader.loadLibrary() method's line
System.loadLibrary(libname);
And in logcat output I got almost similar code but now I know which part of the code is not working.

Further investigation in "Mr. PID 7847" murder case has lead me to the facts that it is not the code that is at fault but in my Galaxy Tab chipset is NVIDIA TEGRA 2 and this is reason my app is not working.
The main line in crash log looks like :
signal 4 (SIGILL), code 1 (ILL_ILLOPC), fault addr 57c48cec
Intro about SIGILL is here and a Related Issue and a Related Article.
So far it seems like its a matter between armeabi-v7a and armeabi. Now I have a MCQ : Please let me know which of the following is correct question by me and explain its answer too.
1) If I have missed or neglected something until now while using Javacv ?
2) Or if Javacv is not Tegra 2 compatible at all and no hope is there ?
3) Or should .SO filesbe compiled with some additional settings (armeabi-v7a and armeabi) which will make it Tegra 2 compatible , in such case how can I do that ?
4) What Should I do to run it on Tegra 2 chipset devices like Galaxy P7500 10.1 Android Tab ?

To get rid of this problem, I have found an alternative way.
Simply check is custom camera is supported on device in which user is using your app.
So that you can handle it and start native camera instead.
private void checkIsCustomCameraSupported()
{
int isNeon = com.javacv.recorder.Util.checkNeonFeature();
if (isNeon == 0)
{
IS_CUSTOM_CAMERA_ENABLED = false;
Toast.makeText(MainActivity.this, "Custom Camera is not supported", Toast.LENGTH_LONG).show();
// finish(); or intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
}
}
