Hello,

I'm trying to use the droid-VNC-server on our own android device.
I pushed the libdvnc_flinger_sdk25.so from nativeMethods/libs/armeabi-v7a on /data/local/tmp with one androidvncserver.

When i start the server without param i have :

Initializing grabber method...
No grabber method selected, auto-detecting...

With tightvnc i can control the device but i'm not able to see the screen.

When I try to run ./androidvncserver -m flinger, I have :

And it automatically stop...

Did you have an idea of ​​what's going on ?
Thanks in advance

@stranchand it looks like its not able to load the flinger lib file. Can you remove all the flinger libs from the /data/local/tmp folder except the one required for your platform...also try renaming it from libdvnc_flinger_sdkxx.so -> libdvnc_flinger_sdk.so

subho007 commented

@stranchand rename /data/local/tmp/libdvnc_flinger_sdk25.so to /data/local/tmp/libdvnc_flinger_sdk22.so

This should work

First, thank you for your replies.

So that's not working

I have the same result as before, I have a black screen and I can control the device..

stranchand commented

When I say that "I can control the device but i'm not able to see the screen" / "I have a black screen" I mean :
When I'm connecting with the client I have one frame which does not appear completely, but immediately after clicking on the screen the vcn client loose the video and at this moment I have a black screen forever.

I would check if files in /data/local/tmp/ have enough permissions. Try to start the vnc server from root user, if you're running it from shell one.
In my case I run libandroidvncserver.so -m flinger and /data/local/tmp/libdvnc_flinger_sdk.so is loaded (also copied it from libdvnc_flinger_sdk25.so). Before that I also had the black screen, and only -m flinger works OK
