I had trouble with the above answers and that's because API 22 and maybe other APIs returns on getApplicationInfo().className in debug/emulation mode:
"com.android.tools.fd.runtime.BootstrapApplication"

Most important thing is that I needed to set the entire path to the class for the class name. (see the changes)

For example, I had the following:
packageName=com.example.user.myapp
className=MainActivity

In Kailash answer I needed to change this line:

shortcutIntent.setClassName("packageName", "className");

to

shortcutIntent.setClassName("com.example.user.myapp", "com.example.user.myapp.MainActivity");

In ChristopheCVBs answer I needed to change this line:

ComponentName comp = new ComponentName(appInfo.packageName, appInfo.className);

to

ComponentName comp = new ComponentName(appInfo.packageName, appInfo.packageName+".MainActivity");
