Does not work with Genymotion

[radj]

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.

[radj]

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.

[radj]

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:

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 :)

[radj]

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/?

[wangrangli42]

I have the same question. But it run well(except the mouse don't work) on the AndroVM which is free version of Genymotion.

[paulmai]

Confirmed, I am also experiencing the same issue. Any ideas on what could be causing this?

[gounthar]

I've got the same issue (mmap failed) with several VNC server apps in Genymotion.

[lalinden]

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
