Here's recompiled APK for 2.1. It installs, but browser does not "see" it. Here's explanation why.
Android 2.2 has a new feature called com.google.android.feature.GOOGLE_PLUGIN. And Flash usesit to embed itself inside browser. So browser in 2.1 does not see plugin.
BUT!There's another thing inside - a permission called android.webkit.permission.PLUGIN. It is already used by Flash Lite on HTC devices. So my APK will work and replace Flash Lite. But I did not test, because I do own... Acer Liquid!
So! HTC users! Try this one! And if it will work instead of your flash lite - report. Your help will be used to port full-blown Flash to other 2.0 and 2.1 devices (yeah! 2.0 is also supported!).
