Despite my manifest stating API8 (2.2) 5 users with 2.1 are showing on my market stats?

I have about 20K acti开发者_C百科ve downloads of my app, but somehow five 2.1 users have sneaked on to my stats.

From manifest:

uses-sdk android:minSdkVersion="8"

My concern is that there are more 2.1 users trying it and unistalling it and thus messing up my active:total ratio, or worse 1 staring me.

This sometimes happens when users have modified firmware. The firmware reports one version, while the kernel may differ.

Could be that your app is pirated and available as direct apk download somewhere so the manifest logic might not take effect..

You should not worry about this, since there's absolutely no way to prevent it from happening. There's just as many incompatibilities in devices that are running different kernels and ROMs, even though they might be running the same Android version.
