安卓各文件存储路径汇总（Android file path)

写下来，省得以后不记得到处翻：

Environment.getDataDirectory() = /data

Environment.getDownloadCacheDirectory() = /cache

Environment.getExternalStorageDirectory() = /mnt/sdcard

Environment.getExternalStoragePublicDirectory(“test”) = /mnt/sdcard/test

Environment.getRootDirectory() = /system

getPackageCodePath() = /data/app/com.my.app-1.apk

getPackageResourcePath() = /data/app/com.my.app-1.apk

getCacheDir() = /data/data/com.my.app/cache

getDatabasePath(“test”) = /data/data/com.my.app/databases/test

getDir(“test”, Context.MODE_PRIVATE) = /data/data/com.my.app/app_test

getExternalCacheDir() = /mnt/sdcard/Android/data/com.my.app/cache

getExternalFilesDir(“test”) = /mnt/sdcard/Android/data/com.my.app/files/test

getExternalFilesDir(null) = /mnt/sdcard/Android/data/com.my.app/files

getFilesDir() = /data/data/com.my.app/files
