I am developing a project which needs to delete/erase the user accounts like Login info and data of Facebook, Twitter, Gmail in Android Device. Need opinions from you...

回答1:

you can do this way,i tried on gmail its working for me and its become clear the gmail apss and no history of log in etc you will just log out but dont know what do you mean by delete?

AccountManager am = AccountManager.get(this);
Account[] accounts = am.getAccounts();
if (accounts.length > 0) {
    Account accountToRemove = accounts[0];
    am.removeAccount(accountToRemove, null, null);
}

Add the following permission as well

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