I have found the Keyboard class, which would let me define a keyboard in an XML resource.

I tried adding one to my activity's XML; finding it at runtime with findViewById ; and then

问题 I have updated SDK for the latest but still I am getting this error .R cannot be resolved to a variable.

问题 Android 2.2 release notes have just been released. ActivityManager.restartPackage method has been deprecated and the description is: the previous behavior here is no longer available to applications because it allows them to break other applications by removing their alarms, stopping their services, etc. Instead 2.2 has given another tool for pesky "task killer" apps by introducing new ActivityManager.killBackgroundProcesses method.

问题 My first post here. This website has been very useful for learning Android programming, thanks to everyone. I have a simple app that loads an MP3 stream and plays it. It works fine on 1.6 and 2.1 but on 2.2 it doesn't quite work right.
