Not able to remove my own custom-account

问题

I have googled for this problem, but I did not find any solution.

I have created my own Custom-Account. When I'm trying to remove the account programmatically using the following code, the account is not be removed:

Account systemAccount = new Account(mainAccount.getDisplayName(), 
                                    getResources().getString(R.string.account_type));
AccountManager.get(Accounts.this).removeAccount(systemAccount, null, null);

Even, when I try to remove the account from Setting, nothing happened. the account is removed only when I uninstall the application.

What should I do?

回答1:

You are not using the Future passed as a parameter to the AccountManagerCallback<Boolean>#run method.

You should provide the callback as the second parameter to: public AccountManagerFuture<Boolean> removeAccount (Account account, AccountManagerCallback<Boolean> callback, Handler handler)

myAccountManager.removeAccount(myAccount, new AccountManagerCallback<Boolean>() {
    @Override
    public void run(AccountManagerFuture<Boolean> future) {
        // This is the line that actually starts the call to remove the account.
        boolean wasAccountDeleted = future.getResult();
    }
}, null);

You should be careful how you call future.getResult(). It should not be called on the main UI thread. This example does not provide that mechanism for brevity.

Two things:

Always get account objects from the AccountManager to change them.

final AccountManager accountManager = AccountManager.get(this);
accountManager.getAccountsByType(Constants.ACCOUNT_TYPE)[0];

Make sure if you're overriding getAccountRemovalAllowedon your Authenticator, you're returning the Bundle with a boolean value of true, this is the default behaviour.

public Bundle getAccountRemovalAllowed(
        AccountAuthenticatorResponse response, Account account)
        throws NetworkErrorException {
    final Bundle result = new Bundle();

    result.putBoolean(AccountManager.KEY_BOOLEAN_RESULT, true);

    return result;
}
