Question

我是Android新手，但最近遇到了问题。在按下登录按钮时，AccountManager将填写帐户详细信息，如下所示。

AccountManager mAccountManager;
    final Account account = new Account(mUsername, Constant.ACCOUNT_TYPE);

    mAccountManager.addAccountExplicitly(account, token, null);

    ContentResolver.setSyncAutomatically(account,
                ContactsContract.AUTHORITY, true);

但是在我按下或在我重新启动应用程序后，我希望从以下位置查看帐户详细信息：

accountManager = AccountManager.get(applicationController.getCurrentActivity());
        accounts = accountManager.getAccountsByType(packageName);

帐户返回[0]，即没有任何内容。请帮帮我。

onAuthenticationResult（string，string）函数调用finishlogin，它存储帐户信息

public void onAuthenticationResult(String error, String token) {
        // Hide the progress dialog
        // hideProgress();
        if (token != null && !"".equalsIgnoreCase(token)) {
            {
                finishLogin(token);
                CommonMethods.getInstance().showAppMsg(
                        "Registered Successfully.");

}
}

这里是finishLogin函数，它接受一个令牌并将其存储在帐户管理器中，并带有用户名

protected void finishLogin(String token) {
         account = new Account(mUsername, Constant.ACCOUNT_TYPE);

        if (mRequestNewAccount) {
            mAccountManager.addAccountExplicitly(account, token, null);
            // Set contacts sync for this account.
            ContentResolver.setSyncAutomatically(account,
                    ContactsContract.AUTHORITY, true);
        } else {
            mAccountManager.setPassword(account, mUsername);
        }

        if (Constant.isCampaign) {
            keyarr = new String[] { "token", "imei", "deviceid", "osversion",
                    "modal", "screen_width", "screen_height", "manufacturer",
                    "simcountrycode", "simoperator", "phonetype",
                    "networktype", "gcmregid", "device_type", "app_version",
                    "download_source", "api_version" };
            valuearr = new String[] { token, imei, androidId,
                    String.valueOf(softwareversion), PhoneModel,
                    String.valueOf(divwidth), String.valueOf(divheight),
                    PhoneMANUFACTURER, simcountrycode, simoperator, phonetype,
                    networktype, Constant.NEWGCM_REGD_ID, "ANDROID",
                    "" + Constant.version, "" + Constant.DOWNLOAD_SOURCE,
                    "" + Constant.API_VERSION };

        } else {
            keyarr = new String[] { "token", "imei", "deviceid", "osversion",
                    "modal", "screen_width", "screen_height", "manufacturer",
                    "simcountrycode", "simoperator", "phonetype",
                    "networktype", "gcmregid", "device_type", "app_version",
                    "api_version" };
            valuearr = new String[] { token, imei, androidId,
                    String.valueOf(softwareversion), PhoneModel,
                    String.valueOf(divwidth), String.valueOf(divheight),
                    PhoneMANUFACTURER, simcountrycode, simoperator, phonetype,
                    networktype, Constant.NEWGCM_REGD_ID, "ANDROID",
                    "" + Constant.version, "" + Constant.API_VERSION };

        }

        signUpScreenModel.WriteDeviceInfo(keyarr, valuearr);
        applicationController.handleEvents(
                ApplicationEvents.EVENT_ID_HOME_FRAGMENT, false);

    }

如果返回true，则必须在onResume（）方法中检查登录主活动的帐户，您应该加载数据，其他建议需要完整代码。

Android：即使在后退或App重启时登录，AccountManager也会返回空
