Do you have templates that match your godot version (commit)?

[mohaalak]

yes I have the correct template version , android export is unstable , it force close sometimes, in some scene it just show a blank screen with camera( in 3d).
for finding out that what's a problem I remove nodes from scenes and export step by step.one problem is that I preload some scenes in my script but I have that scene instanced in editor too, when I remove the instanced scene in editor, export was good to go.
another problem was I have a 3d scene with a spaital a camera and the robotrigged.xml from 3dplatformer it force closes on android. but if I remove the robotrigged instance it export, if I set the main scene the robotrigged it export.

just open the platform 3d from demo and then mess with enviroment and gridmap a little then save export to android it will give you force close:(:(

[mohaalak]

ok I got what's wrong you cannot instance another scene in 2.0 alpha android. I did not check the current repository but that's wrong . @akien-mga can you confirm this?

[mohaalak]

this is correct in head repo , I close it now
