在LG 4G Stylus设备上拍照后我的应用程序崩溃了.
它在galaxy nexus,galaxy S4,LG 4G上运行良好.

我不能把手指放在它上面,它让我发疯…

我正在使用vIEwpager为我的图像和使用theses清单配置：

<activity androID:name="easydeal_androID.MainActivity" androID:configChanges="orIEntation|screenSize" androID:windowsoftinputMode="adjustPan|stateHIDden">

如果有人可以帮助我,我真的很感激！

以下是异常：引起：md52ce486a14f4bcd95899665e9d932190b.JavaProxyThrowable：System.NotSupportedException：无法在EasyDeal_AndroID.FragmentDetailsvehicle类型上找到默认构造函数.请提供缺少的构造函数. —&GT Java.Interop.JavaLocationException：抛出了类型’Java.Interop.JavaLocationException’的异常.

这是跟踪：

它确实解决了这个问题,但是在拍摄了多张照片之后它仍然会崩溃：

解决方法:

看起来你的FragmentDetailsvehicle类中有自定义构造函数,但是你也需要手动添加默认构造函数,即使它实际上什么也没做：

public FragmentDetailsvehicle() {}

见：https://developer.android.com/reference/android/app/Fragment.html

All subclasses of Fragment must include a public no-argument
constructor. The framework will often re-instantiate a fragment class
when needed, in particular during state restore, and needs to be able
to find this constructor to instantiate it. If the no-argument
constructor is not available, a runtime exception will occur in some
cases during state restore.
