Question

I am developing an application which requires to auto populate a
default email field.
The logical choice is to retrieve the email address from the email
client provided by android.
I searched the content providers and did not find anything about the
email client.
How is this information stored?
How can I reach it?

Try this:

AccountManager accManager = AccountManager.get(context);
Account acc[] = accManager.getAccounts();
int accCount = acc.length;
AppConstants.accOnDevice = new Vector<String>();
for(int i = 0; i < accCount; i++){
//Do your task here...
}

Permission:

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
