android - What does this expression mean : "R.string.gcm_registered"? -


i trying enable push notifications on application.

i have client sample code , trying of code implement on application. of have implemented push notifications on apps sure familiar class gcmintentservice.

so copying class on project , configure manifest correctly(or think do) errors in file.

the errors in expressions r.string."something"

for example errors in :

r.string.gcm_registered  r.string.gcm_message  r.string.gcm_deleted  r.string.gcm_error  r.string.gcm_recoverable_error  r.drawable.ic_stat_gcm

the error gcm cannot resolved or not field.

but expression?! class or something?

is on manifest havent configured correctly?

it strings, in example app you're using, in /res/values/strings.xml

you put strings in there have localized place put user visible strings in, have 1. 1 place find strings, if ever want change and/or re-use 2. easy access translation putting translations in per example /res/values-de/strings.xml

look file in whatever example you're using, you'll find xml defined strings. copy them own project, in same place.
