Programmatic sdcard mounting/unmounting

Answer 1

以编程方式挂载 SDCARD..

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

<小时/>

查找文件位置很简单:

我的 SD 卡/我的文件夹名称/视频中有视频，那么路径是

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

<小时/>

检查外部存储是否可用？

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;
}
