Send an SMS from an Android 8.0 using adb

Now, I finally can send SMS through the command line on an Android 8.0-oreo performing next steps:

• Installing the ShellMS app on the phone (once for ever)


• Going on the phone to Settings > Apps > ShellMS > Permissions > Enable all the permissions (once for ever). This step will no longer be necessary once an issue about permissions will be fixed


• Connecting the phone to the computer with USB (and giving permission on the phone for accessing data, if asked)


• Issuing next script on the computer:

#!/bin/bash

phonenumber="$1"

message="$2"

# escape double quotes

message=${
message//\"/\\\"
}
 

adb shell "am startservice --user 0 -n com.android.shellms/.sendSMS -e contact \"$phonenumber\" -e msg \"$message\""
