Why are Log.d() and Log.v() not printing

Question

I have the following test code in my Activity:

@Override
public void onStart() {
    super.onStart();
    Log.e(CLASS_NAME, \"ERROR onStart()\");
    Log.w(C

I had similar problem to this one. However in my case the problem was empty first string. It worked in older version of Android Studio, but stopped working in Android Studio ver 5.6 after update. When I used: Log.d(string1, string2); in my logging wrapper class, then whenever string1 was "", the logcat would ignore it. The solution was to add

if(string1 == null || string1 == "") {
    string1 = "defaultString";
}

before

Log.d(string1, string2);

I hope this helps anyone with this problem.
