You guys probably don't plan to support such trash devices, but I'll post LogCat output anyway:

The first 3 messages are internal log messages that can be ignored and will be removed in a future FastCV release. The next few lines show the configuration and should be "I/" log lines not "E/" so will be changed. Although we have not specifically tested that device, the sample app initially targeted Android 2.3 so that is a problem. Broader device support for the sample app will likely come soon.
If I well informed the Samsung Galaxy ACE is bult with Qualcomm MSM 7227 which is (according to processors lists)
named Snapdragon S1 Scorpion. In the FastCV doc mentioned that the software supports Snapdragons from S2.

FastCV Public API Documentation
The second implementation runs only on Qualcomm Snapdragon S2 and higher chipsets, and is called "FastCV for Snapdragon."
Is it mean that for Samsung Galaxy ACE I cannot use this release of software?
You can use this release for the Samsung Galaxy ACE or any other android phone. The documentation is trying to say that the performance may not be as good on S1 as S2 phones because of less sophisticated hardware. However, it should work.
