Forward SMS to a specified mobile number by keyword

Source code introduction

Often we need to filter text messages and forward them to a specific phone number to prevent missing important content. This program implements this function. You can set all messages to be forwarded, or only forward the content with set keywords. You can set multiple keywords, separated by spaces or commas.
When forwarding all SMS, keyword settings will be ignored. When keyword mode is turned on, ignore the switch of forwarding all SMS. The reason for developing this is that there are some similar functions on the Internet, but most of them forward to email and generally do not provide the function of forwarding SMS. Some forwarding SMS are paid services, and all SMS will be sent to their servers, causing information security and privacy leakage risks.
Pay attention to the package name and file name, and do not write the word SMS forward, otherwise it will be blocked by the firewall.
