I have used FBOs on Android with OpenGL ES 2.0 extensively and with 1.1 on Linux. For 1.1 you need the FBO extensions or use pbuffers. If the OpenGL ES 1.1 drivers you have on your Android device reports having the FBO extensions, they should work. Most of them do because some of the Android SDK OpenGL ES demos require the FBO extensions. This article has example code of using FBOs on 1.1 on Linux:

I think there are also examples in the Android SDK that use VBOs on 1.1 too, such as the "Hello Effects" demo.
