Android无法以编程方式启动启动器活动

Question

I want to implement such scheme: if in activity's onCreate i catch exception -> start launcher activity. I tried to do this in dif ways:

Intent intent = new Intent(this, StartActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setAction(Intent.ACTION_MAIN);
startActivity(intent);

and

Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);

but my app only closes. What is wrong?

Thanks to @Ersin Gülbahar :

Intent startMain = new Intent(this, StartActivity.class);
startActivity(startMain);

So simple.
