unexpected error while executing: start -n "com.example.vaibhav.myapplication/com.example.vaibhav.myapplication.mainactivity" -a android.intent.action.main -c android.intent.category.launcher error while launching activity

................. 1 thing , , am start command taking package name twice though declared correctly in

am start -n "com.example.vaibhav.myapplication/com.example.vaibhav.myapplication.mainactivity" -a android.intent.action.main -c android.intent.category

you should use classified class name activity in androidmanifest.xml.

android:name

the name of class implements activity, subclass of activity. attribute value should qualified class name (such as, "com.example.project.extracurricularactivity"). however, shorthand, if first character of name period (for example, ".extracurricularactivity"), appended package name specified in element.
