如何使用android应用程序创建和上传谷歌电子表格？
我在这上面花了太多时间，所以我想问一下。我想用android创建并上传谷歌电子表格。我知道我应该使用驱动API来实现这一点。我知道如何使用此API（甚至excel文件）创建文件，但当setMimeType设置为application/vnd.google apps.spreadsheet时，我在设备上收到一个错误：尝试创建文件时出错。如何使用android应用程序创建和上传谷歌电子表格？,android,spreadsheet,google-drive-android-api,Android,Spreadsheet,Google Drive Android Api,我在这上面花了太多时间，所以我想问一下。我想用android创建并上传谷歌电子表格。我知道我应该使用驱动API来实现这一点。我知道如何使用此API（甚至excel文件）创建文件，但当setMimeType设置为application/vnd.google apps.spreadsheet时，我在设备上收到一个错误：尝试创建文件时出错。 @Override public void onConnected(Bundle connectionHint) { super.onConnec
