Some time ago, due to customer requirements, a client was used to combine web microsite applications. Here, this application is designed to modify the profile picture, but this page is implemented on the micro-website, which means that the website needs to call the Android method to open files, how is this implemented through webview? After discussion with colleagues on the server, I found that the methods are the same as those on the pc. They call an

In this paper, we describe the method of segmentation and assembly of the Android file by example, which is mainly for the segmentation and assembly of UDP packets. Share for everyone to use for reference. The specific methods are as follows: In general, when you send a file by using a UDP packet, due to the size of UDP packets, a

This article describes the implementation of Android download file function of the complete sample code, for learning and research on Android programming is believed to have some help, especially for Android beginners have some reference value. The full functional code is as follows: Package com.test; Import Java

Resources are additional files that you use in your code and are packaged into your application during compilation. Android supports a variety of different files, including XML, PNG, and JPEG files. The format of an XML file depends on the content it describes. These files describe the types, syntaxes, or formats supported by the files. In consideration of loading efficiency, resources are separated from th

I always think that development is messy, because several projects need to be carried out at the same time, and version iterations are required. I have never studied software engineering and feel a lot of pressure. It seems that the next time you are free, you still need to find a software engineering book to read well. The voice input of Google Pinyin is powerful, and the recognition rate is almost. It may be related to my standard Mandarin. The address of code is: http://code.google.com/p/app

For people engaged in Android development, encountering ANR (application not responding) is a more common problem. In general, if a ANR occurs, the system will generate the trace file in the/data/anr/directory, by analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the ANR, such as high CPU use, the event did not get timely r

This article illustrates the simple File Manager implementation approach for Android development. Share to everyone for your reference, specific as follows: Here using Java I/O, listactivity, Dialog, bitmap and so on to implement a simple File manager, you can view the directory file, modify the

In Android, there are two methods to display the file list in the SD card through ListView: Display by inheriting ListActivity; and display by using BaseAdapter. BaseAdapter is a common base class adapter used to provide display data for ListView, Spinner, and other controls.

The specific analysis is as follows: The Sharedpreferences class provides a simple file storage function, like a program's configuration file can be implemented th

Android Call so The Android virtual machine cannot call the underlying device directly, and we need to use so if we want to call the underlying device. So use C language or C + + writing complete, using NDK to compile, run directly in the Linux kernel. By JNI call So when the basic type can be directly interactive, jstring use a bit cumbersome, so I do a jstring and char* to convert the example. First ste

A lot of times we're sensitive. Google follows a large number of MVC architectures when designing Android, allowing it to be independent of writing public code, artwork, and concrete logic developers. How do you implement a formatted string in the Android resource file Values/strings.xml? Here's a simple example of Android123, and where you might end up using it.
