Android获得所有存储设备位置的最佳方法

public static List<HomeDirBean> getAllExternalStorage(Context context) {  List<HomeDirBean> storagePath = new ArrayList<>();  StorageManager storageManager = (StorageManager) context.getSystemService(STORAGE_SERVICE);  StorageVolume[] storageVolumes;  try {   Method getVolumeList = StorageManager.class.getDeclaredMethod("getVolumeList");   storageVolumes = (StorageVolume[]) getVolumeList.invoke(storageManager);   Method getVolumeState = StorageManager.class.getDeclaredMethod("getVolumeState", String.class);   for (StorageVolume storageVolume : storageVolumes) {    String desc = storageVolume.getDescription(context);    Log.i(TAG, "storageVolume name--->" + desc);    Method getPath = StorageVolume.class.getMethod("getPath");    String path = (String) getPath.invoke(storageVolume);    Log.i(TAG, "StoragePath--->" + path);    //这里需要用StorageManager反射调用getVolumeState函数，而不应该用StorageVolume的getState方法，因为可能会报错    String state = (String) getVolumeState.invoke(storageManager, path);    Log.i(TAG, "storageVolume State--->" + state);    if (Environment.MEDIA_MOUNTED.equals(state)) {     HomeDirBean bean = new HomeDirBean(path, desc);     storagePath.add(bean);    }   }  } catch (Exception e) {   Log.e(TAG, e.getMessage());  }  return storagePath; }
