我试图在我看来添加一个优惠屏幕。

super.onCreate(savedInstanceState);
addPreferencesFromResource(R.layout.preferences);

优惠活动在海伦开始。 java与以下法典:
Intent preferenceIntent = new Intent(this, steamanywhere.com.Preferences.class);
startActivity(preferenceIntent);
在<条码>启动(参考);上,我有以下例外:
android.content.ActivityNotFoundException: Unable to find explicit activity class {steamanywhere.com/steamanywhere.com.Preferences}; have you declared this activity in your AndroidManifest.xml?
但它被宣布。 任何想法?
我研究了许多类似问题,但我没有回答。
