【解决方案1】：

获取外部存储路径 Environment.getExternalStorageState()

final String state = Environment.getExternalStorageState();

if ( Environment.MEDIA_MOUNTED.equals(state) || Environment.MEDIA_MOUNTED_READ_ONLY.equals(state) ) {  // we can read the External Storage...           
    //Retrieve the External Storage:
    final File primaryExternalStorage = Environment.getExternalStorageDirectory();

    //Retrieve the External Storages from the root directory:
    final String externalStorageRootDir;
    if ( (externalStorageRootDir = primaryExternalStorage.getParent()) == null ) {  
        Log.d(TAG, "External Storage: " + primaryExternalStorage + "\n");
    }
    else {
        final File externalStorageRoot = new File( externalStorageRootDir );
        final File[] files = externalStorageRoot.listFiles();

        for ( final File file: files ) {
            if ( file.isDirectory() && file.canRead() && (file.listFiles().length > 0) ) {  // it is a directory (not a External drive)...
                Log.d(TAG, "External Storage: " + file.getAbsolutePath() + "\n");
            }
        }
    }
}
