Share an Android and Java tool that calls RESTful Web services restingWhen we invoke a Web service, it is often the final goal to take an HTTP response and convert it into a value object that will be rendered in the app. Resting can be used to implement this function.Resting, a lightweight rest framework in Java, can be used to invoke a RESTful Web service and transform it to respond to Java objects customi

The android application contains four build blocks: Activity Intent receiver er Service Content Provider 1 activity In an application, an activity is usually a separate screen. Every activity is implemented as an independent class and inherits from the base class of activity. This activity class will display the user interfaces composed of several views controls and respond to the events. 2 intent and intent Filters The intent class is used to descr

Android calls are implemented in two ways:The first method, call the phone to jump to the dial-up interface. The source code is as follows:New= Uri.parse ("Tel:" + "135xxxxxxxx"); intent.setdata (data); StartActivity (intent) ;View CodeThe second method, the call directly to dial, but some third-party ROM (for example: MIUI), not directly dial, but to the user to choose whether to dial, the source code is a

Pushvalue Pushvalue; Public void Setpushvaluecallback (Pushvalue pushvaluecallback) { this. pushvalue = pushvaluecallback;} First declare the interface in the establishment of a set method, the role of the external will be instantiated interface, and then directly at the source of the data generated in the interface method can be calledPushvalue.push ((byte) (Crc160xff), (byte) ((0xff00 CRC16) >> 8);After using a class that uses the Setpushvaluecallback method, the external instance

Android calls the camera to take pictures and get the original photo solution as follows:Note to have permission to read the file, you need to add the following permissions:button click event: Public voidClick (View view) {Intent Intent=NewIntent (mediastore.action_image_capture);//the intention of the camera to capture the pictureIntent.putextra (Mediastore.extra_output, Imagefileuri);//specifies that the

Recently made a query within the small application, the interface is the top of a edittext query box, after the activity, will always play soft keyboard. This blocks the other query condition controls under the query box and feels unfriendly. So now to do is to enter the activity, do not eject the soft keyboard, only manually click the input box will pop up. The implementation method is as follows:Select the acitivity in the Androidmanifest.xml and set his Android:windowsoftinputmode to Statehid

After setting android: parentActivityName, click the return key of the sub-Activity. The parent Activity always calls the OnDestroy () solution, I 've been checking this for a long time and share it with you, The principle is very simple. An Activity declares android: parentActivityName in manifet. At this time, click the return button in the upper left corner of

Android phone has its own camera and library, we do the project sometimes used to upload images to the server, today did a project to use this feature, so put my code down and share with you, the first blog hope that the great God many criticisms.First call the Android album and the camera Code:The code is as follows:Intent Intent = new Intent (mediastore.action_image_capture);//Call the camera that comes w

The location of the anomaly in the source code, grandma, labor tangle for a long time.The great God F2, as long as a tune above that piece of code jumped off. Since this is not the way to go, I see the file has a way to directly convert the URI, so the final code is:public void Onactivityresult (int requestcode, int resultcode, Intent data, Myuri URI) {if (ResultCode! = activity. RESULT_OK) {return; } if (Requestcode = = pick_request) {if (da

Android calls the system method to obtain application information, such as the cache size. 1. android has a way to get the application cache, but it is a little troublesome to use. However, our applications sometimes need to let users know the size of the cache, so that users can promptly clean up the cache. Run the Code directly. The demo is created using

The Android program calls googlemap on the local machine, transmits the start and end positions, and generates a Roadmap Copy codeThe Code is as follows: if (wodeweizhiPoint! = Null ){ If (wodeweizhiPoint. getLatitudeE6 ()! = 0 ){ Float chufajingdu = (float) (wodeweizhiPoint. getLongitudeE6 ()/1E6 ); Float chufaweidu = (float) (wodeweizhiPoint. getLatitudeE6 ()/1E6 ); Float daodajingdu = (float) (AppConstan
