E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.myapplication, PID: 14614, jump page problem

This happens in android studio, because the jump page does not have permission to add, just add permission in AndroidManifest Under the

same package name:

<activity android:name=".MainActivity"/>

different package name

<activity android:name="com.example.administrator.activity_intent.MainActivity"></activity>
里面的mainactivity是你自己的文件名
