IOException thrown by AccountManagerFuture.getResults whereas connection is alive

access-token, android, google-account, oauth-2.0

Solution

The `AccountManager` is converting any network errors into `IOException`'s. A network error could be some sort of unexpected HTTP status, so it might not be directly related to network connectivity. Note that the `AccountManager` supports some, but not all 'oauth2:' type tokens, so that might be related. Try with a token that is known to be supported. Also look at the logcat for hints, there might be some warnings there. Is this the full stack trace?

This works on a GN 4.0.4 (note it is using the system `AccountManager`, not `GoogleAccountManager`):

    AccountManager am = AccountManager.get(this);
    Account[] accounts = accountManager.getAccountsByType("com.google");
    String AUTH_TOKEN_TYPE = "oauth2:https://www.googleapis.com/auth/analytics.readonly";
    am.getAuthToken(accounts[0], AUTH_TOKEN_TYPE, null,
                   this, new AccountManagerCallback<Bundle>() {
                        public void run(AccountManagerFuture<Bundle> future) {
                           try {
                             String token = 
future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
                            System.out.println("token " + token);
                            } catch (...) {}

                            }
                        }, null);

Edit: Here's what I get when copying the token type from your post:

0000000: 226f 6175 7468 323a 6874 7470 733a 2f2f  "oauth2:https://
0000010: 7777 772e 676f 6f67 6c65 6170 6973 2e63  www.googleapis.c
0000020: 6f6d 2f61 7574 682f 3f3f 616e 616c 7974  om/auth/??analyt
0000030: 6963 732e 7265 6164 6f6e 6c79 220a       ics.readonly".

Again, this might be my browser or smth, by check your string (esp. last part)

Problem

The following method systematically throws a IOException when invoked on my Android device whereas the internet connection is alive (I can retrieve emails or connect to gmail using my Android device). Can anyone please help? ``` private void performAuthentication() { Log.d("GAWidget", "performAuthentication"); GoogleCredential credential = new GoogleCredential(); GoogleAccountManager accountManager = new GoogleAccountManager(this); Log.d("GAWidget", "after getting accountManager"); Account account = accountManager.getAccountByName("balteo@gmail.com"); Log.d("GAWidget", "after getting account"+"account.name: "+account.name); accountManager.getAccountManager().getAuthToken(account, "oauth2:https://www.googleapis.com/auth/‌​analytics.readonly", true, new AccountManagerCallback<Bundle>() { public void run(AccountManagerFuture<Bundle> future) { try { String token = future.getResult(15, TimeUnit.SECONDS).getString(AccountManager.KEY_AUTHTOKEN); Log.d("GAWidget", "token: "+token); useToken(token); } catch (OperationCanceledException e) { Log.e("GAWidget", "OperationCanceledException", e); } catch (AuthenticatorException e) { Log.e("GAWidget", "AuthenticatorException", e); } catch (IOException e) { Log.e("GAWidget", "IOException", e); } } }, null); } ``` Edit: Here is the stack trace: ``` 05-27 19:09:04.319: E/GAWidget(12487): IOException 05-27 19:09:04.319: E/GAWidget(12487): java.io.IOException 05-27 19:09:04.319: E/GAWidget(12487): at android.accounts.AccountManager.convertErrorToException(AccountManager.java:1440) 05-27 19:09:04.319: E/GAWidget(12487): at android.accounts.AccountManager.access$400(AccountManager.java:138) 05-27 19:09:04.319: E/GAWidget(12487): at android.accounts.AccountManager$AmsTask$Response.onError(AccountManager.java:1301) 05-27 19:09:04.319: E/GAWidget(12487): at android.accounts.IAccountManagerResponse$Stub.onTransact(IAccountManagerResponse.java:69) 05-27 19:09:04.319: E/GAWidget(12487): at android.os.Binder.execTransact(Binder.java:320) 05-27 19:09:04.319: E/GAWidget(12487): at dalvik.system.NativeStart.run(Native Method) ``` shipped jars: ``` google-http-client-1.9.0-beta.jar google-http-client-android2-1.9.0-beta.jar (only for SDK >= 2.1) google-http-client-android3-1.9.0-beta.jar (only for SDK >= 3.0) gson-2.1.jar guava-11.0.1.jar jackson-core-asl-1.9.4.jar jsr305-1.3.9.jar protobuf-java-2.2.0.jar ```
