announce calls android

There are two ways to implement a photo in Android, one is to call the system's own camera and then use the photo data it returns. Another one is to use the camera class and other related classes to achieve the camera function, this method of the system is relatively high, dyeing is also more complex, the general common application just use the first one can. start the camera code with intent： Copy Code code as follows: Intent Intent

global reference for later use. and Jmethodid/jfieldid and Jobject have no inheritance relationship, it is not a jobject, just an integer, so there is no problem of being released or not, can be saved directly after use. Static Jobject Gs_object=null; Jniexport void Jnicall Java_test_setenev (jnienv *env, Jobject obj) {NBSP;NBSP;NBSP;NBSP;ENV-GT;GETJAVAVM (gs _JVM); Saving to a global variable jvm//the direct assignment of obj to a global variable is not possible, the following function should

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

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

final conversion to Bitmap this parameter. 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

The Code calls the Android Application to uninstallIn Android applications, a few are offered to uninstall their own applications, that is, some of the most uninstall applications. I personally think that, from the product perspective, it is not necessary to provide an uninstallation.The following describes how to uninstall the SDK from a technical perspective.Th
