Installation failed due to invalid APK file?

I just downloaded an example program of AR in metaio. When I run or build the program. The error displayed: Installation failed due to invalid APK file! [2011-08-29 21:15:30 - Example_SDK] Please check logcat output for more details. [2011-08-29 21:15:30 - Example_SDK] Launch canceled!

Here is the logcat. I have read other issues regarding on this matter but it still did not work including making sure the phone and sdk target device version is the same.

I really have no idea what is the problem.

The metaio Mobile SDK is only supported on armeabi-v7a. There will be a native ABI mismatch if you try to install the APK on a device that does not support armeabi-v7a.

I have exactly the same problem as you. From what I understand, I need to run ndk on the librairy since the problem of Native ABI mismatch can be solved that way (found that while Googleing it)

Here's the output of logcat (if it can help us with the issue) :
