http://developer.android.com/reference/android/content/ActivityNotFoundException.html please see the explain of this exception class. ... a call to startActivity(Intent) or one of its variants fails because an Activity can not be found to execute the given Intent. Basically , this exception is an error of activity didn't declare in the manifest file . So it causes an exception was fired. http://blog.csdn.net/andie_guo/article/details/9273909 please see above post . a little suggestion , you may run your program on another well-executed environment and try to find whether the exception occurs or not. If does , you should check the manifest file or relevant files ; otherwise , please check your development environment .
