Android获得内/外置存储卡路径

我们知道android上一般都有外置的存储卡,
但是通过Environment.getExternalStorageDirectory()获取的是内置的存储卡位置 (也有的手机可以在系统中修改默认存储) 那么如何获取外置存储卡的位置呢?

我们可以通过StorageManager来获取多个外置sdcard，代码如下：

StorageManager storageManager = (StorageManager) cxt.getSystemService(Context.STORAGE_SERVICE);            try {                Method method = StorageManager.class.getDeclaredMethod("getVolumePaths");                method.setAccessible(true);                Object result = method.invoke(storageManager);                if (result != null && result instanceof String[]) {                    String[] pathes = (String[]) result;                    StatFs statFs;                    for (String path : pathes) {                        if (!TextUtils.isEmpty(path) && new File(path).exists()) {                            statFs = new StatFs(path);                            if (statFs.getBlockCount() * statFs.getBlockSize() != 0) {                                pathsList.add(path);                            }                        }                    }                }            } catch (Exception e) {                e.printStackTrace();                File externalFolder = Environment.getExternalStorageDirectory();                if (externalFolder != null) {                    pathsList.add(externalFolder.getAbsolutePath());                }            }        }        return pathsList.toArray(new String[pathsList.size()]);
