backwards-compatibility

问题 I have found a MooTools version of Nivoo Slider that (in theory) will work with our MooTools dropdown menu. However, the menu is using MooTools 1.2.x, and Nivoo is using 1.3.2 or 1.4.0. Every time I try and use both the menu and the slider, the menu stops working. Are the versions of the MooTools framework not backward compatible? Also, are these plugins compatible or is one overriding the other? I don't know enough about JS to correct my errors or rewrite the function call. Is there a good

问题 we already have a bunch of similar question to this but all of them was related to backward compatibility or they are on eclipse (as far i understand) but i think problem is occurring while inflating the cardView class it was working fine on my emulator (SDK 23) but when am trying it on my other emulator (SDK 19) am getting this error and the error is pointing me to this line : @Override public RecyclerView.ViewHolder onCreateViewHolderImpl(ViewGroup viewGroup, final ParallaxRecyclerAdapter

问题 I want to be able to convert a Access 2010 database to multiple different older version by using a script So if I feed a 2010 Access to the script I want it to spit out one of the following versions: 2000, 2002, 2003 or 2007. How is this possible? I'm not looking for a complete script, but more a pointer in the right direction or perhaps an example of how it can be done. * EDIT * TmpName = Destination & "\" & dbDisname & "_2002.mdb" If Dir(TmpName) <> "" Then FS.deletefile TmpName End If

问题 This question, as you may have inferred from the title, is really two questions in one. First Question: Must I use HTTP/2.0 to send Apple Push Notifications? On the APNs Provider API documentation provided by Apple, the opening paragraphs specify: The provider API is based on the HTTP/2 network protocol. There are several other references to HTTP/2.0 throughout the documentation. However I don't see (which is not to say it's not there) anything specifying that HTTP/2.0 must be used. Does this

问题 Should I build an app that targets Android 2.2 and release it on the Android Marketplace; Would the app be available for download and use on devices running a version of Android OS lower than the targeted version of the app? - Let's say Android OS version 1.6. What would happen if a user (with an Android OS version 1.6 powered device) were to attempt to run the app? Would they be prompted to update their OS or just receive an error message? 回答1: It depends what you have in the minSdkVersion
