@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Log.e("SMS","Hello World");   //not showing
    Log.v("SMS","Hello World");   //not showing
    Log.i("SMS","Hello World");   //not showing
    Log.d("SMS","Hello World");   //not showing

    Log.i("sms","Hello World");   //showing
}

为什么登录Logcat不适用于上面代码中的某些行？
