apps rackspace for mobile

Today the Android encounters a requirement that does not allow the user to completely clear the app Private directory (/data/data/package name/), but Android by default the user clicks the erase data in the app information The button completely clears all the data files in the application's private directory, including Sharedpreference, cache files, databases, and other important data.If we don't want users to do this, we need to use The android:managespaceactivity property, which is a property

corresponding operation, I do not explain in detail here, paste a modified code of the actual running, IOS, the application of the THREE20 library, and compatible with the tturlrequest cache mechanism.The Java version of Android I took out the HTTP part of the actual running code, because there are some related configuration, the code does not compile properly, but also put here for reference.Android-rsa-http.zipUsage examples: 123 BaiyiApiRequest request = newBaiyiApiReque

Sencha Touch can also use plugins such as maps, multimedia, and more. 1. Map ComponentsWe define the map component through ext.map , whose xtype is map. In addition to using the plug-in, but also to call Google 's map API used by the JS file, the code is as follows:After introducing the file, we can write the JS code to display the map:Ext.require (' Ext.map ') ext.application ({//Omit other configuration items ... launch:function () {var Map = ext.create (' Ext.map ', { Usecurrentlocation:true}

When talking about the optimization technology for applications running on battery power supply devices, some application developers may doubt or understand why they need to consider this issue. Because peekmes

setting value value for each option , Passing value value into the sort method and sort them as required. Second, searchin DataView, there is a way to filter data in the Data Warehouse, with the following code:Store.filter (' LastName ', ' Tom ');This sentence means to filter out such data, its lastName property value is Tom. Similarly, if we want to implement the user search function, define a search box and pass the value entered by the user into the filter function. It is also possible to

emphasize. Using the store component to define the data,field defines the properties of the data in the Data Warehouse, where the properties include name and URL . The data can then be defined. Once we've defined the data store , we'll define the template, which we've talked about before, in fact, using the data to edit the content within the HTML. Finally, we define the DataView component. the store attribute selects a defined Data Warehouse,itemtpl selects the template that was previously

the current network environment, the app product performance is good, the user does not have to wait and endure, this is to judge an app is the important standard of quality or not.Performance is not a purely technical issue, but also a policy-level consideration, and developers need to balance speed and effectiveness. For example, when a message is clicked, it will always go into the message list instead of just displaying a single message, which, while sacrificing some speed, can make the mes

the value for each option . The value values are passed into the sort method and sorted according to the requirements. Second, searchThere are methods for filtering data in the Data Warehouse in DataView. The code is as follows:Store.filter (' LastName ', ' Tom ');This sentence means that the data is filtered out. The value of its lastName property is Tom. Similarly. Suppose we want to implement the user's search function. Define a search box to pass the value entered by the user into the f

Now the front-end technology development is fast, the front-end can do the app, then the project, you will also encounter some functions called Android phone base, such as the call camera, complete scanning QR code functionLet me explain to you the process of invoking this feature in my project.First we need an intermediate frame,hbuilderhttp://www.html5plus.org/doc/zh_cn/accelerometer.html This is html5+ 's document address, we found the barcode module,There are so many, and then we look downF

JS in the code into their own HTML page, the page all about the size of the settings can be replaced with REM, such as the use of REM instead of PX, you can make the screen large content scaled up, is all the content Oh, if you project all the content uses REM.REM Adaptation in mobile apps

As the name suggests, the so-called mobile phone program can be installed in the mobile phone program, improve the original system of deficiencies and personalization. With the development of science and technology, the function of mobile phone is more and more, more and more powerful. is not as simple as the past, the current development to the computer can be c
