我们正在尝试实施GDK玻璃器皿验证;已将我们的测试版APK上传至Google Glass团队,并成功实施了我们的MyGlass登录页面.我们现在尝试通过此处列出的步骤访问令牌：
https://developers.google.com/glass/develop/gdk/authentication#retrieving_accounts_on_glass
但是最后一步,String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);导致以下异常：
09-22 18:07:24.126: I/AccountManagerService(519): Sharing credentials is not allowed: canceling. 09-22 18:07:24.313: W/System.err(5822): android.accounts.OperationCanceledException 09-22 18:07:24.313: W/System.err(5822): at android.accounts.AccountManager$AmsTask.internalGetResult(AccountManager.java:1503) 09-22 18:07:24.313: W/System.err(5822): at android.accounts.AccountManager$AmsTask.getResult(AccountManager.java:1531) 09-22 18:07:24.313: W/System.err(5822): at android.accounts.AccountManager$AmsTask.getResult(AccountManager.java:1452) 09-22 18:07:24.313: W/System.err(5822): at com.mycom.app.MainActivity$5.run(MainActivity.java:234) 09-22 18:07:24.313: W/System.err(5822): at android.accounts.AccountManager$11.run(AccountManager.java:1427) 09-22 18:07:24.313: W/System.err(5822): at android.os.Handler.handleCallback(Handler.java:733) 09-22 18:07:24.313: W/System.err(5822): at android.os.Handler.dispatchMessage(Handler.java:95) 09-22 18:07:24.313: W/System.err(5822): at android.os.Looper.loop(Looper.java:149) 09-22 18:07:24.313: W/System.err(5822): at android.app.ActivityThread.main(ActivityThread.java:5061) 09-22 18:07:24.313: W/System.err(5822): at java.lang.reflect.Method.invokeNative(Native Method) 09-22 18:07:24.313: W/System.err(5822): at java.lang.reflect.Method.invoke(Method.java:515) 09-22 18:07:24.313: W/System.err(5822): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 09-22 18:07:24.313: W/System.err(5822): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:602) 09-22 18:07:24.313: W/System.err(5822): at dalvik.system.NativeStart.main(Native Method)
我们试图通过Mirror API推送的请求就是这样形成的(并返回一个OK状态代码)：
POST https://www.googleapis.com/mirror/v1/accounts/google_user_token/com.ourcom.app.session/ourapp_username
BODY
{"authTokens":[{"type":"com.ourcom.app.session","authToken":"****************"}]}
HEADERS
{"Authorization":"Bearer ya29.iAAf********","Content-Type":"application/json;charset=utf-8"}
这是我们当地的玻璃代码：
AccountManager accountManager = AccountManager.get(this);
// Use your Glassware's account type.
Account[] accounts = accountManager.getAccountsByType("com.ourcom.app.session");
// Your auth token type.
final String AUTH_TOKEN_TYPE = "com.ourcom.app.session";
if (accounts.length > 0) {
accountManager.getAuthToken(accounts[0],AUTH_TOKEN_TYPE,null,this,new AccountManagerCallback<Bundle>() {
@Override
public void run(AccountManagerFuture<Bundle> future) {
try {
String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
//do something with token
});
} catch (Exception e) {
//handle exception
//this is where we get our OperationCancelledException
e.printStackTrace();
}
}
},null);
} else {
//handle not authed state
}
什么可能导致这种错误？ Mirror POST URL末尾的用户名是否应该与特定内容匹配,或者我们可以自由使用我们自己的东西吗？
