How read/write file in sdcard using PhoneGap?

Since Android 4.4, apps are restricted to read-only access outside of their sandbox. The only place the app has write access to is within its sandboxed areas:

• in /data/ area, e.g. file:///data/data/your.app.id/
• in internal /sdcard area, e.g. file:///storage/emulated/0/Android/data/your.app.id/
• in external SD card area (if present) e.g. file:///storage/emulated/1/Android/data/your.app.id/ - note: this is not accessible via cordova-plugin-file

It is not possible for an app to write to other locations outside of these sandboxed areas.
