我目前正在开发一个 android 应用程序,并且正在尝试集成 Google Drive。I'm having a problem with the account picker, that when the account is chosen and it returns into the onActivityResult function the resultCode is -1 which I believe it should be 0 to mean that it was successful.
以下是我打开帐户选择器的方式
credential = GoogleAccountCredential.usingOAuth2(context, DriveScopes.DRIVE);
startActivityForResult(credential.newChooseAccountIntent(), REQUEST_ACCOUNT_PICKER
credential
是一个全局变量,所以整个类都可以访问这个变量。
下面是 onActivityResult 的代码
else if (resultCode == REQUEST_ACCOUNT_PICKER)
{
if (resultCode == RESULT_OK && intent != null && intent.getExtras() != null)
{
String accountName = intent.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
SharedPreferences settings = context.getSharedPreferences("prefs", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("google_drive_account_name", accountName);
editor.putBoolean("drive_sync_upload_download_required", true);
editor.commit();
}
}
它进入 else if 语句很好,但是当它检查 resultCode 是否等于 RESULT_OK 时,它返回 false,因为 resultCode 由于某种原因被设置为 -1。我假设 -1 表示某些事情发生了故障,但我在 logCat 中看不到任何错误消息。
感谢您的任何帮助,您可以提供。
