A wrapper around Android Log class to show the calling method as a hyperlink in Android Studio

HLog

This is a quick code snippet wrapping the Android Log class to show the calling method in a hyperlink. I found this solution in this stackoverflow answer: http://stackoverflow.com/a/10599298/334209

Note that it's a bit hacky. The formatting cannot be really modified as it's dependant to the way stacktraces are rendered in Android Studio.

Result:

HLog.java

package com.example.myapplication;

import android.util.Log;

/**

public class HLog {

    public static int v(String tag, String msg) {
        return Log.v(tag, getHMsg(msg));
    }

    public static int v(String tag, String msg, Throwable tr) {
        return Log.v(tag, getHMsg(msg), tr);
    }

    public static int d(String tag, String msg) {
        return Log.d(tag, getHMsg(msg));
    }
