Environment中涉及到外部存储路径和储存大小API（测试机：魅族MX2，用其他测试机测试结果会有不同）：

System.out.println("getExternalStorageDirectory.getAbsolutePath===="+Environment.getExternalStorageDirectory().getAbsolutePath());// /mnt/sdcard

System.out.println("getExternalStorageDirectory.getPath===="+Environment.getExternalStorageDirectory().getPath());// /mnt/sdcard

System.out.println("getExternalStorageDirectory.getName===="+Environment.getExternalStorageDirectory().getName());// sdcard

System.out.println("getExternalStorageDirectory.getParent===="+Environment.getExternalStorageDirectory().getParent());// /mnt

System.out.println("getExternalStorageDirectory.getFreeSpace===="+Environment.getExternalStorageDirectory().getFreeSpace()); //12124454912

System.out.println("getExternalStorageDirectory.getTotalSpace===="+Environment.getExternalStorageDirectory().getTotalSpace());//12624855040

System.out.println("getExternalStorageDirectory.getUsableSpace===="+Environment.getExternalStorageDirectory().getUsableSpace());//12124454912

System.out.println("getExternalStorageState===="+Environment.getExternalStorageState());//mounted

System.out.println("getDataDirectory.getAbsolutePath===="+Environment.getDataDirectory().getAbsolutePath());// /data

System.out.println("getDataDirectory.getPath===="+Environment.getDataDirectory().getPath()); // /data

System.out.println("getDataDirectory.getName===="+Environment.getDataDirectory().getName());// data

System.out.println("getDataDirectory.getParent===="+Environment.getDataDirectory().getParent());// /

System.out.println("getDataDirectory.getFreeSpace===="+Environment.getDataDirectory().getFreeSpace());//1912451072

System.out.println("getDataDirectory.getTotalSpace===="+Environment.getDataDirectory().getTotalSpace());//2113748992

System.out.println("getDataDirectory.getUsableSpace===="+Environment.getDataDirectory().getUsableSpace());//1912451072

System.out.println("getDownloadCacheDirectory.getAbsolutePath===="+Environment.getDownloadCacheDirectory().getAbsolutePath());// /cache

System.out.println("getDownloadCacheDirectory.getPath===="+Environment.getDownloadCacheDirectory().getPath());// /cache

System.out.println("getDownloadCacheDirectory.getName===="+Environment.getDownloadCacheDirectory().getName());// cache

System.out.println("getDownloadCacheDirectory.getParent===="+Environment.getDownloadCacheDirectory().getParent());// /

System.out.println("getDownloadCacheDirectory.getFreeSpace===="+Environment.getDownloadCacheDirectory().getFreeSpace());//201908224

System.out.println("getDownloadCacheDirectory.getTotalSpace===="+Environment.getDownloadCacheDirectory().getTotalSpace());//206405632

System.out.println("getDownloadCacheDirectory.getUsableSpace===="+Environment.getDownloadCacheDirectory().getUsableSpace());//201908224

注意：涉及到大小的API sdk必须到大于9！
