The android APK installation method is very simple. I will share with you how to install the APK file to the android simulator graphic tutorial. 1) first start the android simulator, find the emulatorfile in the toolsfolder of Android sdk, and double-click emulator.exe to s

Analysis of App engineering files For information on how to create one of the simplest Android apps please refer to the link: Android Learning Notes (i) Environmental installation and the first Hello World http://www.jb51.net/article/52593.htm The completed engineering files are shown in the following illustration, and some of the major documents are analyzed in this paper.

Start analyzing Android todayRoot file system startup process.When the Android system is started, "init =/init" is usually set in the kernel boot parameters. In this way, if the kernel is successfully mounted to the file system, the INIT program in the root directory is run first. What does this program do? We only hav

The example in this article describes the method of sharedpreferences file storage operations in Android programming. Share to everyone for your reference. 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

This article is an example of the Android implementation of the URI to get the real path into file method. Share to everyone for your reference. The implementation methods are as follows: Uri uri = Data.getdata (); String[] proj = {MediaStore.Images.Media.DATA}; Cursor actualimagecursor = Managedquery (uri,proj,null,null,null); int actual_image_column_index = Actualimagecursor.getcolumnindexorthrow (Me

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.

Android configuration file (3) ---- root node of the application 1. Generally, when an Android application is generated, the default AndroidManifest. xml file contains some default Android: backupAgent = "string" Android:

A file encoding test is conducted to prepare for the next file. Four files with different codes must be prepared. The file name is specified in the code. The xml Code is as follows:Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: orienta

(1) The android.mk file first needs to specify the Local_path variable to find the source file. As a general caseAndroid.mk and the source files that need to be compiled are in the same directory, so they are defined as follows:local_path:=$ (call My-dir)The above statement means that the LOCAL_PATH variable is defined as the directory path of the cost file. (2)
