Answer 1

as per my understanding this issue is happening because of three reason

Reasons

1) first is lack of internet connectivity

2) second is your google api key is missmatching

3) third if key is ok then your provided package name during key generation is not exact same as your project package name

Solutions

for first you need to check your internet conncetion is working or not then you need to go further

for second and third you need to create key with proper steps If your using eclipse then

Eclipse-->windows-->Preferences-->Android-->Build you will get SHA key

Use that SHA key to generate your android key

after pasting SHA key append your project package name by following symbol ";"

for example

YOR_SHA_KEY;YOUR_PROJECT_MAIN_PACKAGE_NAME then generate key finally you will get google map key for android use that one hope it will resolve your problem make sure that your using same pakcage name which is your project package name

hope it will solve your problem happy coding :)
