Admob error in Eclipse? - Android

Eclipse is showing an error in android:configChanges line in my AndroidManifest.xml:

<activity android:name="com.google.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"></activity>

and the error is,

error: Error: String types not allowed (at 'configChanges' with value 'keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize').

I resolved it by setting target=android-13 in project.properties file.. After changing it don't forget to do Project-> Clean

APK signed with a certificate that is not yet valid - Android?

While publishing the app I got the below error,

"You uploaded an APK signed with a certificate that is not yet valid. You need to sign your APK with a certificate that is currently valid."

After several Google searches, I resolved this issue by changing the system date of the computer.. I changed my system date to some earlier date, generated a new keystore and uploaded the app.. it worked like a charm :)
