This is possible, even multiple manners.

If both applications are from the same developer they could use the same shared user id. This is an attribute in the AndroidManifest.xml, android:sharedUserId. When different applications/apks have the same userid they are able to read each others files. When using this technique, files are still prive to the rest of the OS, but are readable/writable by other apks from the same developer.

Another posibility is using the sdcard to share data. That storage is publicly available.

Android has built-in support for sharing data with other applications through the use of ContentResolvers. This does not work for files, but is probably the preferred way to shared data between applications.
