Posted 2021-07-09 hankern

1、SD卡路径

String ROOT_DIR= Environment.getExternalStorageDirectory().getAbsolutePath();

本机为：/storage/emulated/0

2、系统分区路径

ROOT_DIR= Environment.getRootDirectory().getAbsolutePath();

本机为：/system

3、外部存储上公共文件的路径

ROOT_DIR= Environment.getExternalFilesDir("").getAbsolutePath();

本机为：/system/storage/emulated/0/android/data/com.example.testopenfile/files/test

通过手机的文件浏览器看到的路径为/Android/data/com.example.testopenfile/files/test

3、音乐、视频、图片等公共文件路径

ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_MUSIC").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_PODCASTS").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_RINGTONES").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_ALARMS").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_NOTIFICATIONS").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_PICTURES").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_MOVIES").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_DOWNLOADS").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_DCIM").getAbsolutePath();
            ROOT_DIR= Environment.getExternalStoragePublicDirectory("DIRECTORY_DOCUMENTS").getAbsolutePath();

本机为：/storage/emulated/0/DIRECTORY_MUSIC

/storage/emulated/0/DIRECTORY_PODCASTS

/storage/emulated/0/DIRECTORY_RINGTONES

/storage/emulated/0/DIRECTORY_ALARMS

/storage/emulated/0/DIRECTORY_NOTIFICATIONS

/storage/emulated/0/DIRECTORY_PICTURES

/storage/emulated/0/DIRECTORY_MOVIES

/storage/emulated/0/DIRECTORY_DOWNLOADS

/storage/emulated/0/DIRECTORY_DCIM

/storage/emulated/0/DIRECTORY_DOCUMENTS

4、用户数据路径

ROOT_DIR= Environment.getDataDirectory().getAbsolutePath();

本机为：/data

5、下载的缓存路径

ROOT_DIR= Environment.getDownloadCacheDirectory().getAbsolutePath();

本机为：/data/cache

6、应用程序缓存路径

ROOT_DIR=getApplicationContext().getCacheDir().getAbsolutePath();

本机为：/data/user/0/com.example.testnativecplusplus/cache

7、 应用程序数据路径

ROOT_DIR=getApplicationContext().getDataDir().getAbsolutePath();

本机为：/data/user/0/com.example.testnativecplusplus

8、 应用程序文件路径

本机为：/storage/emulated/0/Android/data/com.example.testnativecplusplus/cache

12、 应用程序备份路径

ROOT_DIR=getApplicationContext().getNoBackupFilesDir().getAbsolutePath();
