英文:
Trying to acquireTokenSilentAsync from android app
问题
我目前正在使用以下代码连接到 Azure 应用：
implementation 'com.microsoft.identity.client:msal:1.4.0'
通过 acquireToken() 方法成功连接到应用，我能够得到用户响应并将其保存在 SharedPrefs 中。
在下一次登录时，我尝试使用以下方式执行 acquireTokenSilentAsync：
SharedPreferences pref = getSharedPreferences();Gson gson = new Gson();String json = pref.getString("IAccount", "");if (!json.isEmpty()) {Account account = gson.fromJson(json, Account.class);AcquireTokenSilentParameters parameters = new AcquireTokenSilentParameters.Builder().withScopes(Arrays.asList(scopes)).forAccount(account).fromAuthority(getAuthority()).withCallback(getSilentAuthInteractiveCallback()).build();application.acquireTokenSilentAsync(parameters);}
但是，我在 onError 回调中收到以下异常：
E/onError: exception : com.microsoft.identity.client.Account cannot be cast to com.microsoft.identity.client.MultiTenantAccount
有什么想法，是什么导致了这个问题？
非常感谢。

I'm currently using
> implementation 'com.microsoft.identity.client:msal:1.4.0'
to connect to the app via azure , my acquireToken() works fine and I get the user in response ( I save it in the SharedPrefs)
After that (next login) I'm trying to do acquireTokenSilentAsync like so :
SharedPreferences pref = getSharedPreferences();Gson gson = new Gson();String json = pref.getString("IAccount", "");if(!json.isEmpty()){Account account = gson.fromJson(json, Account.class);AcquireTokenSilentParameters parameters = new AcquireTokenSilentParameters.Builder().withScopes(Arrays.asList(scopes)).forAccount(account).fromAuthority(getAuthority()).withCallback(getSilentAuthInteractiveCallback()).build();application.acquireTokenSilentAsync(parameters);}
And get to the onError callback with the exception of :
> E/onError: exception : com.microsoft.identity.client.Account cannot be cast to com.microsoft.identity.client.MultiTenantAccount
Any ideas what's missing ?
Much Appreciated.

特别是，他们不使用 Gson，并且他们进行了类型转换以防止你在他们的示例代码中遇到的异常。
我建议首先尝试像这样进行类型转换：
IMultiTenantAccount multiTenantAccount = (IMultiTenantAccount)account;
然后将其用作 forAccount() 方法的参数。

In particular, they don't use a Gson and they cast the account to prevent the exception you get in their example code.
I would start by trying to cast like this:
IMultiTenantAccount multiTenantAccount = (IMultiTenantAccount)account;
and using that as the argument in forAccount().
