我仅在 android 4.2.2 上收到此异常 (ActivityNotFound)，同时从自定义视图启动活动。这适用于 4.1.1 及以下的所有设备。

有没有人在 4.2.2 遇到过类似的问题？

从我的自定义视图启动活动的代码

Intent intent = new Intent(getContext(), MyActivity.class);
intent.putExtra(Constants.EXTRAS1, serializable);
intent.putExtra(Constants.EXTRAS2, serializable);           
((Activity)getContext()).startActivityForResult(intent, Constants.MY_ACTION);

好的，问题出在清单上，

我在清单中声明了这项活动，

 <activity android:name="com.sample.MyActivity" android:theme="@android:style/Theme.Translucent"
         android:label="@string/app_name" android:configChanges="orientation|keyboardHidden"> 
         </activity>

从声明中删除包引用后，它开始工作，如下所示，

 <activity android:name=".MyActivity" android:theme="@android:style/Theme.Translucent"
             android:label="@string/app_name" android:configChanges="orientation|keyboardHidden"> 
             </activity>

我不确定为什么它只会在这个活动中表现得这样，因为我的应用程序中有其他活动声明了包引用并且工作正常，虽然奇怪。
