关于Android文件存储路径： 参考:彻底搞懂Android文件存储---内部存储，外部存储以及各种存储路径解惑_ 雨季莫忧离的博客-CSDN博客 1、Environment.getDataDirectory() = /data 这个方法是获取内部存储的根路径 2、getFilesDir().getAbsolutePath() = /data/user/0/packname/files 这个方法是获取某个应用在内部存储中的files路径 3、getCacheDir().getAbsolutePath() = /data/user/0/packname/cache 这个方法是获取某个应用在内部存储中的cache路径 4、getDir(“myFile”, MODE_PRIVATE).getAbsolutePath() = /data/user/0/packname/app_myFile 这个方法是获取某个应用在内部存储中的自定义路径 方法2,3,4的路径中都带有包名，说明他们是属于某个应用 ………………………………………………………………………………………… 5、Environment.getExternalStorageDirectory().getAbsolutePath() = /storage/emulated/0 这个方法是获取外部存储的根路径 6、Environment.getExternalStoragePublicDirectory(“”).getAbsolutePath() = /storage/emulated/0 这个方法是获取外部存储的根路径 7、getExternalFilesDir(“”).getAbsolutePath() = /storage/emulated/0/Android/data/packname/files 这个方法是获取某个应用在外部存储中的files路径 8、getExternalCacheDir().getAbsolutePath() = /storage/emulated/0/Android/data/packname/cache 这个方法是获取某个应用在外部存储中的cache路径 先安利一个GitHub的Android工具类代码集合：AndroidUtilCode/README-CN.md at master · Blankj/AndroidUtilCode · GitHub 感兴趣的可以去看看，个人感觉很好用，已经star了~ 压缩文件成zip的工具类就是在上面扒下来的： 建议直接用我这个类，后面加了几个获取所有文件名的方法。 ZipUtils.class: package cnwy.xda.threedpolygontest.utils;
