I'm very new to android studio and in my first app I want to build an sos app, my sos app specifically sends a message via sms with the current location. When I first built it, it only works on android 5.0 and down, it will not work in 6.0 and up and now I've tried to look at the logcat and the logcat says it needs a permission to send sms so I gave it a permission using the code below this paragraph and now it runs in android 6.0 but it's not sending messages... {if(checkselfpermission(Manifest.permission.SEND_SMS)==PackageManager.PERMISSION GRANTED);}
can you help me here is my manifest my file
<?xml version="1.0" encoding="utf-8"?>
