so,here code above.i should add more details..but have said all..

you not have class named com.example.boot.bootcompletereceiver, @ least based on code have shown in answer.

while have class named bootcompletereceiver:

• it inner class of mainactivity, , bootcompletereceiver not named com.example.boot.bootcompletereceiver

• it regular inner class of mainactivity (no static keyword), , android not create instance of anyway, if had right name in manifest

either move bootcompletereceiver regular standalone java class in own .java file, or make public static class inside mainactivity. in latter case, fully-qualified class name manifest entry com.example.boot.mainactivity$bootcompletereceiver.
