I get this error when I attempt to run my app. "Unable to resolve target 'android-11'"
Either:
Download the API Level 11 SDK from the SDK Manager, or
Update your project to use a build target that you have (e.g., Project > Properties > Android in Eclipse)
Along with the AVD remaining on the ANDROID boot up screen.
Either:
Have patience and wait for the AVD boot to complete, or
Buy a faster computer, or
Switch to the x86 emulator
