我实际上是试图从我的扑动应用程序发送短信,而无需用户的互动.我知道我可以使用url_launcher启动短信应用程序但我实际上想要在没有用户交互的情况下发送短信或从我的颤动应用程序启动短信.
有人可以告诉我这是否可行.
非常感谢,Mahi
实际上,以编程方式发送短信,您需要实现一个平台频道并用于SMSManager发送短信.
例:
Android部分:
首先添加适当的权限AndroidManifest.xml.
<uses-permission android:name="android.permission.SEND_SMS" />

然后在你的MainActivity.java:
package com.yourcompany.example;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.util.Log;
import io.flutter.app.FlutterActivity;
import io.flutter.plugin.common.MethodCall;
import io.flutter.plugin.common.MethodChannel;
import io.flutter.plugins.GeneratedPluginRegistrant;
public class MainActivity extends FlutterActivity {
private static final String CHANNEL = "sendSms";

super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(

public void onMethodCall(MethodCall call, MethodChannel.Result result) {
if(call.method.equals("send")){
String num = call.argument("phone");
String msg = call.argument("msg");
sendSMS(num,msg,result);
}else{
result.notImplemented();
}

});
}
private void sendSMS(String phoneNo, String msg,MethodChannel.Result result) {
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, msg, null, null);
result.success("SMS Sent");
} catch (Exception ex) {
ex.printStackTrace();
result.error("Err","Sms Not Sent","");
}
}

希望这有帮助!
**注意:
1.示例代码不显示如何处理版本6.0及以上版本的Android设备的权限.如果使用with 6.0实现权限调用代码.
这个例子也没有实现选择双卡手机的SIM卡.如果在双卡手机上没有为短信设置默认SIM卡,则可能不会发送短信.
