和我想不出哪来的问题。一切似乎是正确的（对我）的问题我manifest.The活动申请为你所看到的：

And i can't figure out where's the issue. everything seems to be correct (to me) in my manifest.The activity in question is registred as you can see:

感谢您的帮助Dawnkeeper！但我仍然有同样的问题，我得到了很多差评 任何更多的想法将是非常美联社preciated !!

Thank you for your help Dawnkeeper! but i'm still having the same issue, and i'm getting a lot bad ratings Any more ideas will be very appreciated!!

推荐答案

您在名称中引用包

 android:name="aladin888.dessin.Splash"

应

android:name=".Splash"

修改

当我们发现这并不是真正的问题。另一个提示是这样的：

As we found out this isn't really the problem. Another hint is this:

Caused by: java.lang.NullPointerException
at android.app.Activity.setRequestedOrientation(Activity.java:4453)

我搜索了一会儿，但无法找到具有这个方法在给定线的Andr​​oid版本。我发现了什么是这种方法并没有在一段时间改为：

I searched for a while, but could not find a android version that has this method at the given line. What I found out is that method has not changed in a while:

 public void setRequestedOrientation(int requestedOrientation) {
       if (mParent == null) {
           try {
                ActivityManagerNative.getDefault().setRequestedOrientation(
                        mToken, requestedOrientation);
            } catch (RemoteException e) {
                // Empty
            }
        } else {
            mParent.setRequestedOrientation(requestedOrientation);
        }
    }

我看到这个失败的唯一机会是当ActivityManagerNative.getDefault（）返回null。我找不到任何针对此问题有帮助。

The only chance I see for this failing is when the ActivityManagerNative.getDefault() returns null. I couldn't find anything helpful for this issue.
