I know, other people asked the same question, but the answers don't work for me.
I tried this https://github.com/jehy/Android-GetOwnerInfo/blob/master/Android-get-owner-contact-info.java in this way:
OwnerInfo i = new OwnerInfo(this);
System.out.println(i.accountName);
System.out.println(i.email);
System.out.println(i.id);
System.out.println(i.phone);
System.out.println(i.name);
i.accountName gives me the email, but all other deliver null.
and this How to get the Android device's primary e-mail address in this way:
MyLoaderManager mLoaderManager = new MyLoaderManager(this);
getLoaderManager().initLoader(0, null, (LoaderCallbacks<Cursor>) this);
with the code from the Link in MyLoaderManager.
and played with the Account Manager, but nothing could give me my Name(or I used them in the wrong way?). But other Apps like Vine, Pinterest or Twitter can propose me my Name during the registration process, so there must be a way. So, how do they do this?
