Does not work with Genymotion
I am new to Android development (started just this month) and I am already diving into customizing this app. Please bear with me :)
I tried on both Nexus One and S4 virtual devices on Genymotion and it doesn't seem to work. Both virtual devices had Google Play installed so I installed droid VNC server from Google Play.
It always shows "Couldn't start server :(" everytime I try to start it. I adb'd into the virtual device and it turns out /data/data/org.onaips.vnc/lib is empty! No dependency so files were found.
I am not sure yet if this is a Genymotion or Droid VNC apk issue?
The devices should be root. If the root devices not work, maybe you can try to build the source code by the following command $cd droidVNCserver $ndk-build $./updateExecsAndLibs.sh
Then the .so file will be generated to the droidVNCserver/lib folder.
The virtual device is already rooted, it passes with Root Checker Basic.
I will try that. I will also probably try copying from the SO from an installation on a real device and copy it into the virtual device.
OK, it may have been a bad idea to copy .so files from real device into emulator due to the difference in architecture. The device is arm(?) and the Genymotion device needs the x86.
So I did the recompilation with the NDK and got the x86 .so files. Still fails. And I can't get anything useful from logcat: V/VNCserver( 2229): Running as root...

What can I do next?
Updates: Still not working but I got these logs from running libandroidvncserver.so from shell:

Cleaning up...
Not sure why flinger load fails when I have these files in x86 arch: /data/data/org.onaips.vnc/lib//libdvnc_flinger_sdk14.so /data/data/org.onaips.vnc/lib//libdvnc_gralloc_sdk14.so
Gralloc also seems to have loaded successfully but init fails... I'll try to rebuild libandroidvncserver.so with more debug. I don't know how to do this yet, I'll find my way but tips will help :)
Okay, I looked at the logs more carefully and the framebuffer.c code. In the logs, it says:
line_lenght=0 xres=600, yres=1024, xresv=600, yresv=1024, xoffs=0, yoffs=0, bpp=16
..
mmap failed
mmap fails because it is given a zero fbSize. fbSize is zero because line_length is zero.
There is no ioctl error but what does this do?
ioctl(fbfd, FBIOGET_FSCREENINFO, &fscrinfo) != 0
I'm starting to compare the logs of a working setup and the failing one. It's only til now that I shouldn't be looking in /data/data/org.anaips.vnc/lib but in /data/data/org.anaips.vnc/files instead.

So I checked on the Genymotion setup, and the files are actually there. Whew. I tried running /data/data/org.onaips.vnc/files/androidvncserver manually on the AVD but it doesn't seem to have x86 architecture. How do I build x86 into these binaries in /data/data/org.onaips.vnc/files/?
I have the same question. But it run well(except the mouse don't work) on the AndroVM which is free version of Genymotion.
Confirmed, I am also experiencing the same issue. Any ideas on what could be causing this?
I've got the same issue (mmap failed) with several VNC server apps in Genymotion.
Well, hello. Iam try to use the app from google play on galaxy S2 and galaxy tab 8 (android 4.x), in both, the app dont work, say that pixel deep is not supported, or something like...
I install the enviroment to build the app with eclipse/ndk, etc.. I can build de project, and run on emulador (api-15), but dont runs on emulator.. the app starts.. but when I try to start vnc in the app, the follow message appear:
..(571): Error! Could not find daemon file, /data/data/org.onaips.vnc/lib/libandroidvncserver.so
Can you have an ideia about this ?
thanks
