Use the following code to get the launcher activity of all packages:

final PackageManager pm = getPackageManager();

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);

List<ResolveInfo> appList = pm.queryIntentActivities(mainIntent, 0);
Collections.sort(appList, new ResolveInfo.DisplayNameComparator(pm));

for (ResolveInfo temp : appList) {
    Log.v("my logs", "package and activity name = "
            + temp.activityInfo.packageName + "    "
            + temp.activityInfo.name);
}

This is the easiest solution you can use. And it works perfectly.`

private String getLauncherActivityName(){
        String activityName = "";
        final PackageManager pm = getPackageManager();
        Intent intent = pm.getLaunchIntentForPackage(getPackageName());
        List<ResolveInfo> activityList = pm.queryIntentActivities(intent,0);
        if(activityList != null){
            activityName = activityList.get(0).activityInfo.name;
        }
        return activityName;
    }

Even though the answers above answer directly the OP's question I would like to add my two cents:

/** Backwards compatible method that will clear all activities in the stack. */
public void startLauncherActivity(Context context) {
    PackageManager packageManager = context.getPackageManager();
    Intent intent = packageManager.getLaunchIntentForPackage(context.getPackageName());
    ComponentName componentName = intent.getComponent();
    Intent mainIntent = IntentCompat.makeRestartActivityTask(componentName);
    context.startActivity(mainIntent);
}

Here I do not only get the launcher activity of the application, but also am clearing all the backstack of the activities (which is what I actually needed when I triggered the launcher activity). I call this in case of expired auth token for example.

Important thing is to use IntentCompat, otherwise one has to resort to Intent flag Intent.FLAG_ACTIVITY_CLEAR_TASK, which is introduced only in API 11.

late but the better way it will give the exact intent to launch an activity

PackageManager pm = getPackageManager();
Intent intent=pm.getLaunchIntentForPackage(pacakgeName);
startActivity(intent);
