He said

- he don't want to loose his BTC.
- he is a traveller.

Exporting addresses from Android to PC will secure those addresses even if the phone is lost

I would never suggest that a newbie try to directly handle private keys, there is far too much danger involved in messing something up. If physical loss of a phone is a concern (and I agree it should be), usage of a deterministic wallet plus properly backing up the seed is much better advice IMO.

OP is a newbie, so I am not willing to suggest OP to store whole balance in an Android.

Malware which targets mobile devices is considerably less common than PC-based malware, and some mobile devices are currently invulnerable to bitcoin-stealing malware (those which cannot yet be easily rooted such as iOS 8.3, most boot-locked android phones running 5.0.2, etc.).

OP is using an Android phone. By mobile, I mean 'Android'. Sorry! I should have told earlier. There are some reasons. If you also consider practical problems additionally to technical problems, I don't think it is good to store whole balance in a mobile especially when you travel a lot.

Aside from physical loss (which I addressed above), losses from malware are a real threat, and they are much smaller threat on mobiles than they are on desktops (at least for the time being...). IMO newbies should be steered towards mobile wallets, especially deterministic ones, not away from them.

(I certainly agree with you that large amounts shouldn't be stored in any hot wallet though.)
