Answer 1

write the java package name and all folders name in lowercase, it will work fine...

Answer 2

In my case I was mentioned the package name in small letters only. But for few of the activities I named it with partial name i.e android:name=".ContactUs" . After I solved it by prefixing full package name before all the activity name, service name and broadcast provider name in Manifest file.

Working code

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="vcan.doit.com">

<!-- To auto-complete the email text field in the login form with the user's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />

Answer 3

<activity android:name="MainActivity"

should be formed like

<activity android:name="com.company.appname" 

to do this without errors go to package (right click) > android tools > rename app package

Answer 4

make sure your package name is in small letters... worked for me

Answer 5

Change your

android:name="MainActivity"

TO

android:name=".MainActivity"

OR add the fully qualified package name in lowercase before your class name

android:name="thepackage.MainActivity"

Do change all the attributes named as android:name inside the activity tags as I suggested.
