Solution 1:

Declare all the activity which you are calling in manifest file inside the tag as

<activityandroid:name=".temperature"/><activityandroid:name=".weight"/>

or if you use these classes in different package then you have to declare with the package as

<activityandroid:name="com.org.xxx.temperature"><activityandroid:name="com.org.xxx.weight">

check your manifest file..it may helpful to you...
