</application>

You have added ".SomeView" in Menifest. This class is not your Activity Class. Remove it from Menifest. — Mit Bhatt, Oct 21 '15 at 12:19
it is activity class. you can see in my question i write it as activity. — sara sara, Oct 21 '15 at 12:35

Your error say that the activity CropActivity is not find. If you look closely to the error you will see that the activity you try to launch is android.app.cut.SomeView$CropActivity. But in your manifest you declared .CropActivity for the path of the crop activity.

So you should either move CropActivity in his own file in the same package as the other app OR change the declaration in your manifest to .SomeView.CropActivity.

they are all in the same package. – sara sara Oct 21 '15 at 12:32
@sarasara but are they in separate files? – Klotor Oct 21 '15 at 12:38

@sarasara then that is what he meant - if you want them to stay in one file then change the `.CropActivity` to `.SomeView.CropActivity` otherwise move them to separate files and leave the manifest as it is. :) – Klotor Oct 21 '15 at 12:44
I don't know what cause the problem. but by changing the package name it runs without any error. – sara sara Oct 21 '15 at 12:45

Delete your manifest and recreate it. That should fix it.

EG in maven you just do a clean install on the project and it will re create the manifest on its own.
