Where is the temp folder on Android devices?

Question

Where is the temp folder located on Android phones?

Answer 1

The temporary directory is /data/local/tmp.

I've seen some comments that claim you need to be rooted to access it but I'm not sure that's true. Whilst it is true that you need root to freely access /data, this is not required for /data/local/tmp.

I have verified this on Android 5.1.1.
