Installation failed due to invalid APK file?

Question

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.

Solution

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.
