Java.lang.noclassdeffounderror: Android.security.messagedigest

In my application I use MessageDigest.getInstance('SHA-1') to get SHA1, it can run successfully in android 2.3, but it can't run in android 4.0 and it will show the below exception

Solution 1:

From reading around googlegroups it sounds like android.security.MessageDigest was removed in Honeycomb. Unfortunately I am yet to find evidence of this in the Android developer documentation.

Try using java.security.MessageDigest instead.
