在使用Google Calendar API尝试在Google日历中插入和发送事件时，我似乎未能授权使用OAuth2.0。
由于某些原因，问题似乎发生在这段代码中的某个地方，并最终抛出了一个异常，该异常在 GoogleAuthException 中被捕获。值得注意的是，如果我删除了try / catch块，它将成功到达CreateCalenderEventTask中的 event.insert （稍后被调用）但会被 UserRecoverableAuthIOException <捕获/ strong>而不是。
try {
// If the application has the appropriate access then a token will be retrieved, otherwise
// an error will be thrown.
mCredential = GoogleAccountCredential.usingOAuth2(mActivity,
Arrays.asList(GoogleCalendarUtils.SCOPES));
mCredential.setSelectedAccountName(emailAccount);
String accessToken = mCredential.getToken();
Log.e(TAG, "ACCESS TOKEN" + accessToken);
// Success.
return true;
} catch (GoogleAuthException unrecoverableException) {
// Failure.
Log.e(TAG, "UNRECOVERABLE: " + Log.getStackTraceString(unrecoverableException));
return false;
} catch (IOException ioException) {
// Failure or cancel request.
Log.e(TAG, "IO EXCEPTION: " + Log.getStackTraceString(ioException));
return false;
}
