[Solved] Sharing Screenshot

cocos2d-x
1

I’m going to share a screenshot of my game by calling a Java function in my code. I used RenderTexture to save the screenshot. I wonder if I should save the image somewhere in the sdcard and then share the image from that path in my Java function or there is a way to share the image without manipulating the sdcard.

Thanks

There is other way is send Texture data via JNI to java code. you need write your own plugin in proj.android to get that work.

Hi @namkazt

Thanks for your reply. I think the link you provided do this job in the opposite way that I wanted. Anyway maybe the best way is saving the image in the internal storage using RenderTexture and then sharing it via JNI using FileProvider or something like that without the WRITE_EXTERNAL_STORAGE permission.

i do not test that way but i think Save + Send path + Load is slower than just passing data.
android often using NC21 format ( 5+ version will use another - already note in API page but can force to use NC21) and you can pass raw byte[] to cocos2d-x and convert from YUI_NC21 to RGB then load that data to Image. i tested it on my camera plugin and it output smooth like native code.

Note: my way can be use when want to capture data from camera with native performance but if you just want share one image so better save and load.

Hi @namkazt

Thanks. For now I want to share an image containing the current score of the player and some sprites of my game, like most of the games share button and I think save and load would be fine for this purpose(correct me if I’m wrong). Anyway, I would be happy if you provide some code and explain more your method.
