Recently, I am working on an image upload function. I need to provide the path for uploading images to the SD card. I have read some examples on the Internet. The code is very simple after debugging. The layout file is as follows: Copy codeThe Code is as follows: Android: layout_width = "fill_parent" Android: layout_he

When you use MediaPlayer to play a local Mp3 file , you need to be aware of the problem with access paths and access permissions .1. Access path:/storage/emulated/0 This path is the root path of the phone, you can download the es file browser software to view the current playing MP3 specific path, through Environment.getexternalstoragedirectory (). GetPath () gets /storage/emulated/0 This sdcard path This

When we do Android development, we often have this experience, because the customer's device models are different, resulting in a variety of problems, but for developers, because there is no log log files, it is not easy to locate the exact location of the problem. So we need a tool that can write the program log to the SD card file, like the Web log4j. At this t

1, because the simulator must be installed under the system disk, so the default SD card file is also stored in the C disk, then the expansion of capacity will inevitably lead to the reduction of C disk space, which is usually intolerable to users, so you also need to transfer it to the hard disk of other more free partitions, The following functions can be used to facilitate the implementation of the Force

This example mainly implements Android to get the data in the Assets folder and write it to the SD card, which is mainly to read the database in the Assets folder and write it to the SD memory card. The complete sample code is as follows: Import Java.io.File; Import Ja

Suppose the SD card folder is in/mnt/sdcard when Google comes with a simulator or a real machine debug. This is a belief that we all know.but today when debugging with Genymotion. found that the/mnt/sdcard not open the folder, at that time did not pay attention to other information. Think it is the ADB, eclipse what the problem, after restarting them still can't open, after a struggle, found an important cl

The Android program function Copies files in the assets folder to the SD card (including subfolders) of the mobile phone and androidassets. Recently, the function is to copy all files (including sub-files) in the asset folder to the specified directory. The method used is nothing more than AssetManager. However, the problem here is that both subfolders and subfol
