Hello All,
I assembled the logic below which is supposed to start at boot and
launch the "Hello World" program. What I get is an error "02-19
23:09:04.517: E/AndroidRuntime(3975): java.lang.RuntimeException:
Unable to instantiate activity ComponentInfo{com.needham.startatboot/
com.needham.startatboot.StartAtBootActivity}:
java.lang.InstantiationException:
com.needham.startatboot.StartAtBootActivity "
Any help appreciated
Best,
Tom B
