Android Emulator does not work on Ubuntu after upgrading Android Studio to 2.0 - Qt library not found

Question

Today, I updgraded my Android Studio installation to version 2.0. I updated it manually (download the .zip, because the update mechanism just telled me that there is a new version but offered no possibility for direct update in Android Studio). When I now try to start an emulator, I receive this error message:

ERROR:./android/qt/qt_setup.cpp:33:Qt library not found at /home/kcd/Android/Sdk/tools/lib/qt/lib Could not launch '/home/kcd/Android/Sdk/tools/qemu/linux-x86/qemu-system-x86_64': No such file or directory

I checked this directory and notices that the path name is .../qemu/linux-x86_64/qemu-system_x86_64 and not .../qemu/linux-x86/qemu-system_x86_64

So I renamed the direcory to match the correct path. After trying to launch the emulator, it puts this error message:

ERROR:./android/qt/qt_setup.cpp:33:Qt library not found at /home/kcd/Android/Sdk/tools/lib/qt/lib

emulator: WARNING: VM heap size set below hardware specified minimum of 228MB

This application failed to start because it could not find or load the Qt platform plugin "xcb". emulator: WARNING: Setting VM heap size to 384MB

My system is Ubuntu 14.04 64 bit. Before the update to Android Studio 2.0, everything worked fine.

Can anyone help?

EDIT: After testing the answer from Anurag Maheshwari, this error disappeared. Then I have got the following error message:

Cannot launch AVD in emulator. Output: emulator: WARNING: VM heap size set below hardware specified minimum of 228MB emulator: WARNING: Setting VM heap size to 384MB emulator: ERROR: Could not load OpenGLES emulation library [lib64OpenglRender]: lib64OpenglRender.so: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden console on port 5554, ADB on port 5555 emulator: ERROR: Could not initialize OpenglES emulation, use '-gpu off' to disable it.

I tried to use '-gpu off', but it still does not want to start...

Answer 1

I got the same problem. It may be occur due to your 64bit linux didn't match to the avd you installed. Try copy 'lib' folder from your Android sdk location -> ../Android/Sdk/tools/lib64/qt/lib to ../Android/Sdk/tools/lib/qt/lib It worked for me.

Finally I've managed it. While testing from command line (-gpu off), it does not seem to work, but when I use the Virtual Device Manager and choose "Emulated Performance - Graphics --> Software - GLES 2.0" instead of "Hardware - GLES 2.0", the emulator starts. Unfortunately, it a bit slower now, and I wonder why it worked before the upgrade, but my emulators are running for now.
