如果您有此选项卡,我从Android 4.4的某些设备(如Galaxy Tab3 8.0(lt01wifi))收到此错误,请回复。 该应用程序在其余设备上运行良好。 请帮我!我的收视率很高......

我无法弄清问题在哪里。在我的清单中,一切似乎都是正确的(对我而言)。有问题的活动会被注册,如您所见:

感谢Dawnkeeper的帮助!但我仍然遇到同样的问题,而且我的评分很差 任何更多的想法将非常感谢!!
答案 0 :(得分:1)
您正在引用名称
中的包 android:name="aladin888.dessin.Splash"
应该是
android:name=".Splash"
修改强>
我们发现这不是真正的问题。另一个提示是:
Caused by: java.lang.NullPointerException
at android.app.Activity.setRequestedOrientation(Activity.java:4453)
我搜索了一会儿,但找不到在给定行上有此方法的Android版本。我发现的是,方法在一段时间内没有改变:
public void setRequestedOrientation(int requestedOrientation) {
if (mParent == null) {
try {
ActivityManagerNative.getDefault().setRequestedOrientation(
mToken, requestedOrientation);
} catch (RemoteException e) {
// Empty
}
} else {
mParent.setRequestedOrientation(requestedOrientation);
}
}
我发现失败的唯一机会是ActivityManagerNative.getDefault()返回null。我找不到任何有用的问题。
