RuntimeException尝试使用其原生Android库对foursquare OAuth2进行身份验证进行身份验证

Question

我有一个使用foursquare-android-oauth的应用程序，它在我测试的任何地方都运行正常，但我有一个报告崩溃的用户（Here is the crash report）

我不知道你需要什么细节，请评论，我会加上它！

我使用以下方式启动身份验证：

            private static final String CLIENT_ID                       = "MY CLIENT ID";
            final Intent intent = FoursquareOAuth.getConnectIntent(LoginActivity.this, CLIENT_ID);
                startActivityForResult(intent, REQUEST_CODE_FSQ_CONNECT);

然后用户被发送到4sq应用程序，我在这里再次拿起它：

@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    switch (requestCode) {
        case REQUEST_CODE_FSQ_CONNECT:
            onCompleteConnect(resultCode, data);
            break;

        case REQUEST_CODE_FSQ_TOKEN_EXCHANGE:
            onCompleteTokenExchange(resultCode, data);
            break;

        default:
            super.onActivityResult(requestCode, resultCode, data);
    }
}



private void onCompleteConnect(final int resultCode, final Intent data) {
    final AuthCodeResponse codeResponse = FoursquareOAuth.getAuthCodeFromResult(resultCode, data);
    final Exception exception = codeResponse.getException();

    if (exception == null) {
        // Success.
        final String code = codeResponse.getCode();
        performTokenExchange(code);
    } else {
        if (exception instanceof FoursquareCancelException) {
            // Cancel.
            UiUtils.toastMessage(this, getString(R.string.login_cancelled));
        } else if (exception instanceof FoursquareDenyException) {
            // Deny.
            UiUtils.toastMessage(this, getString(R.string.login_denied));
        } else if (exception instanceof FoursquareOAuthException) {
            // OAuth error.
            UiUtils.toastMessage(this, getString(R.string.login_error));
        } else if (exception instanceof FoursquareUnsupportedVersionException) {
            UiUtils.toastMessage(this, getString(R.string.login_error));
        } else if (exception instanceof FoursquareInvalidRequestException) {
            UiUtils.toastMessage(this, getString(R.string.login_error));
        } else {
            UiUtils.toastMessage(this, getString(R.string.login_error));
        }
    }
}

private void onCompleteTokenExchange(final int resultCode, final Intent data) {
    final AccessTokenResponse tokenResponse = FoursquareOAuth.getTokenFromResult(resultCode, data);
    final Exception exception = tokenResponse.getException();

    if (exception == null) {
        final String accessToken = tokenResponse.getAccessToken();
        // Success.
        UiUtils.toastMessage(this, getString(R.string.connect_success));
        saveAccessToken(LoginActivity.this, accessToken);
        startActivity(new Intent(LoginActivity.this, MainFragmentActivity.class));
        finish();
    } else {
        if (exception instanceof FoursquareOAuthException) {
            // OAuth error.
            UiUtils.toastMessage(this, getString(R.string.login_error));
        } else {
            UiUtils.toastMessage(this, getString(R.string.login_error));
        }
    }
}

private void performTokenExchange(final String code) {
    final Intent intent = FoursquareOAuth.getTokenExchangeIntent(this, CLIENT_ID, CLIENT_SECRET, code);
    startActivityForResult(intent, REQUEST_CODE_FSQ_TOKEN_EXCHANGE);
}

public static boolean saveAccessToken(final Context context, final String accessToken) {
    final SharedPreferences prefs = context.getSharedPreferences(SHARED_PREFERENCES_NAME, Context.MODE_PRIVATE);
    prefs.edit().putString(ACCESS_TOKEN_KEY, accessToken).commit();
    BackupUtils.requestBackup(context);
    return true;
}

它自身的例外没有意义：

`java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.foursquare.android.nativeoauth.okenExchangeActivity$TokenExchangeTask)`

我没有编辑TokenExchangeActivity $ TokenExchangeTask的原始代码，这段代码显然是可序列化的！

static class TokenExchangeTask extends AsyncTask<String, Void, AccessTokenResponse> implements Serializable
