Question

我正在尝试关注developer.android.com的课程而我正陷入困境 am.getAuthToken( myAccount_, AUTH_TOKEN_TYPE,options,this,new OnTokenAcquired(),new Handler(new OnError()));

我无法获得myAccount_的内容;它是与帐户数组相关联的帐户吗？ Account[] accounts = accountManager.getAccountsByType("com.google");

class OnTokenAcquired上的令牌部分也会产生一个错误，表示它不是变量，我应该将其设为全局变量，即使它是AccountManager.KEY_AUTHTOKEN中的常量也是如此？

This is the other link for the Authentication lesson我在该tutorioul中收到了DIALOG_ACCOUNTS，showDialog(DIALOG_ACCOUNTS)和manager.getAuthToken(account, AUTH_TOKEN_TYPE, null, activity, new AccountManagerCallback<Bundle>()的错误消息。由于我目前遇到的错误，我还没有进一步深入。

我不明白为什么会发生这些错误？我认为只是我没有投入正确的变量。

有什么建议吗？

这是我复制的代码。

public class AccountManagerActivity extends Activity {

AccountManager accountManager = AccountManager.get(this);

Account[] accounts  = accountManager.getAccountsByType("com.google");

String AUTH_TOKEN_TYPE = "Manage your tasks";
String your_api_key;
String your_client_id;
String your_client_secret;
String token;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    URL url = new URL("https://www.googleapis.com/tasks/v1/users/@me/lists?key=" + your_api_key);
    URLConnection conn = (HttpURLConnection) url.openConnection();

    conn.addRequestProperty("client_id", your_client_id);

    conn.addRequestProperty("client_secret", your_client_secret);

    conn.setRequestProperty("Authorization", "OAuth " + token);



    AccountManager am = AccountManager.get(this);
    Bundle options = new Bundle();

    am.invalidateAuthToken(token, AUTH_TOKEN_TYPE);
    am.getAuthToken(
        /*Error here*/ myAccount_,                     // Account retrieved using getAccountsByType()
        AUTH_TOKEN_TYPE,                // Auth scope
        options,                        // Authenticator-specific options
        this,                           // Your activity
        new OnTokenAcquired(),          // Callback called when a token is successfully acquired
        new Handler(new OnError()));    // Callback called if an error occurs
}

}

然后是OnTokenAcquired类

public class OnTokenAcquired implements AccountManagerCallback<Bundle> {

public void run(AccountManagerFuture<Bundle> result) {
    // TODO Auto-generated method stub
    // Get the result of the operation from the AccountManagerFuture.
    Bundle bundle = result.getResult();

    // The token is a named value in the bundle. The name of the value
    // is stored in the constant AccountManager.KEY_AUTHTOKEN.
  /*Error here*/  Token = bundle.getString(AccountManager.KEY_AUTHTOKEN);
    Intent launch = (Intent) result./*Error here*/get(AccountManager.KEY_INTENT);
    if (launch != null) {
       /*Error here*/ startActivityForResult(launch, 0);
        return;
    }


}

}

Answer 1

am.invalidateAuthToken(token, AUTH_TOKEN_TYPE);

应该是

am.invalidateAuthToken(AUTH_TOKEN_TYPE, token);

验证OAuth2服务课程（麻烦）
