Starting point:Traditional game simulators (FC, Neo, FBA, GBA, Mame, n64, NDS, and PSP) are all moved to Android phones, the game Rom is then saved to the SD card and run through the simulator. However, considering that mobile games must follow the fast forward and fast forward principles, I have implemented the following micro-innovations on this basis: 1. direc

Android 4.4 and later systems have read and Write permission restrictions on level two external storage devices, resulting in applications that may not be able to read and write external SD cards, and the following methods can be lifted.1, root system.2.

This paper illustrates the method of realizing SD card reading database with Android programming. Share to everyone for your reference, specific as follows: First add permissions to the Manifest: Then add the method in Mainactivity: Sqlitedatabase db; private final String Database_path = android.os.Environment. Getexte Rnalstoragedirectory

Recently the company framework has just been transplanted, because the framework program to call subroutines, each subroutine is a so file, there are hundreds of, all so and apk packaging unrealistic, timely upgrade maintenance is also very troublesome. So you need to put the SD card. Consider two different ways1The/data/app-lib/package name/so file that is placed on the device (and a default path is not re

How to determine files? You can use Cursor to traverse the database and compare the value of the INTERNAL_CONTENT_URI field. This is a Uri, which stores the complete path of the multimedia file on the Android mobile phone SD card. [Java] Copy codeThe Code is as follows: Uri originalUri = MediaStore. Images. Media. EXTERNAL_CONTENT_URI; // If it is a Video, it is

When the Android system is started, it will automatically detect the SD card files and collect music files to generate a database file. We only need to access the information in the database table to obtain the required File Code as follows: Obtain the cursor object to access the media resources in the cursor. If (cursor. moveToFirst () {do {String title = curso
