Answer 1

here a code snipped I am doing it ( sorry for german commetns ) don't forget to set the propper permissions in the manifest file.

/**
 * ueberprueft, ob es den account fuer diese app schon gibt und legt ihn
 * gegebenenfalls an.
 * 
 * @param none
 * @return void
 */
public void verifyAccount() {
    if (debug)
        Log.i(TAG, "verifyAccount() ");

    boolean bereitsAngelegt = false;
    String accountType;
    accountType = this.getPackageName();

    AccountManager accountManager = AccountManager
            .get(getApplicationContext());
    Account[] accounts = accountManager.getAccounts();
    for (int i = 0; i < accounts.length; i++) {
        if (debug)
            Log.v(TAG, accounts[i].toString());
        if ((accounts[i].type != null)
                && (accounts[i].type.contentEquals(accountType))) {
            bereitsAngelegt = true;
            if (debug)
                Log.v(TAG, "verifyAccount(): bereitsAngelegt "
                        + accounts[i].type);
        }
    }

    if (!bereitsAngelegt) {
        if (debug)
            Log.v(TAG, "verifyAccount(): !bereitsAngelegt ");

        // This is the magic that addes the account to the Android Account
        // Manager

        AccountManager accMgr = AccountManager.get(this);

        String password = "some_password";

        if (debug)
            Log.d(TAG, "verifyAccount(): ADD: accountName: "
                    + Konst.accountName + " accountType: " + accountType
                    + " password: " + password);

        final Account account = new Account(Konst.accountName, accountType);
        if (debug)
            Log.v(TAG, "verifyAccount(): nach final Account account ");
        try {
            accMgr.addAccountExplicitly(account, password, null);
        } catch (Exception e1) {
            if (debug)
                Log.v(TAG, "verifyAccount(): Exception e1 " + e1.toString());
            this.finish();
        }
        if (debug)
            Log.v(TAG,
                    "verifyAccount(): nach accMgr.addAccountExplicitly() ");
    } else {
        if (debug)
            Log.v(TAG, "verifyAccount(): bereitsAngelegt ");
    }
} // end of public void verifyAccount()

i hope this helps a little bit.
