Answer 1

These type of Errors generally occurs when we accidentally close these libraries(by close unrelated projects,etc) which are automatically generated In Project Explorer of Eclipse like:

• appcompat_v7
• appcompat_v7_2
• appcompat_v7_3
• appcompat_v7_4
• appcompat_v7_5
• appcompat_v7_6
• appcompat_v7_7
• appcompat_v7_8
• appcompat_v7_9
• appcompat_v7_10
• appcompat_v7_11
• appcompat_v7_12
• appcompat_v7_13
• appcompat_v7_14

As soon as I open these files,all the errors in my app were vanished !

If It till then didn't work then do Project -> Properties -> Android -> Is Library -> Add.. -> And add appcompat_v7_*
