Programmatic sdcard mounting/unmounting

Answer 1

以编程方式安装SDCARD ..

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
 Uri.parse("file://" +  Environment.getExternalStorageDirectory())));

查找文件的位置很简单：

我的sdcard /我的文件夹名称/视频中有视频，然后路径是

File videoPath = new File(Environment.getExternalStorageDirectory()+"/myFolderName/video1.mp4");

检查外部stroge是否可用??

boolean mExternalStorageAvailable = false;
boolean mExternalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
    // We can read and write the media
    mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
    // We can only read the media
    mExternalStorageAvailable = true;
    mExternalStorageWriteable = false;
} else {
    // Something else is wrong. It may be one of many other states, but all we need
    //  to know is we can neither read nor write
    mExternalStorageAvailable = mExternalStorageWriteable = false;
}

Answer 2

试试这个..

Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) {
File f = Environment.getExternalStorageDirectory();

这将为您提供外部存储路径。您也可以使用：“/ mnt / sdcard” 如果仍然不清楚，请查看此链接：Link
