Android: Detecting USB

Question

Is there any way to know(programmatically) in your Activity/Application that the user has connected your phone to PC through USB?

Answer 1

This works for me.

Add this on your AndroidManifest.xml

And Create your BroadcastReceiver.

public class PlugInControlReceiver extends BroadcastReceiver {

    @Override public void onReceive(final Context context, Intent intent) {

        String action = intent.getAction();
        Log.v("PlugInControlReceiver","action: "+action);

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){

            if(action.equals("android.hardware.usb.action.USB_STATE")) {

                if(intent.getExtras().getBoolean("connected")){

                    Toast.makeText(context, "USB Connected", Toast.LENGTH_SHORT).show();
                }else{

                    Toast.makeText(context, "USB Disconnected", Toast.LENGTH_SHORT).show();
                }
            }
        } else {
            if(action.equals(Intent.ACTION_POWER_CONNECTED)) {

                Toast.makeText(context, "USB Connected", Toast.LENGTH_SHORT).show();
            }
            else if(action.equals(Intent.ACTION_POWER_DISCONNECTED)) {

                Toast.makeText(context, "USB Disconnected", Toast.LENGTH_SHORT).show();
            }
        }  
   }      
}
