Emulator doesn't start in eclipse

I've tried to find answers and similar problems, but nothing has fixed the problem.
I created a project and wanted to run the emulator to check if everything is working fine. But the emulator doesn't start up. It gives the following ouput, in console:
[2015-01-08 10:20:06 - MTNInfoHub] ------------------------------

Please help me.

Had this problem with Android Studio. To fix it, I just ran Android Studio as administrator.

My android emulator doesnt launch

I installed the Android Development Tool and created my first app but when I run the app, the emulator doesnt launch.The console reads:
[2013-06-18 14:36:57 - MyFirstApp] Android Launch!
[2013-06-18 14:36:57 - MyFirstApp] adb is running normally.
[2013-06-18 14:36:57 - MyFirstApp] Performing com.example.myfirstapp.MainActivity activity launch
[2013-06-18 14:37:19 - MyFirstApp] Launching a new emulator with Virtual Device 'AVD'
Unfortunately, it never launches. The following is what I have tried to do to solve the problem:
I created AVD both by graphical user interface and command line but it didnt run.
I tried to open task manager and stop the adb.exe process then run it again but no.
I tried to kill the adb server and restart it by command line but again no, didnt run.
I finally tried to launch the emulator on command line and this is what it says (directly translated): "a problem interrupted the program, trouble-free operation. Windows will close the program and notify you if a solution to the problem is available."
Please help.

After a long struggle, I decided to install a new Operating System. The emulator can now launch.

android app won't install

I recently bought a couple of books on android programming and have been having a terrible time getting anything to work. I finally got one of the books sample code to show up. I noticed that when it worked that in the eclipse console it showed installation logging. In everything else I've tried it never gets to that point. All I ever get is what is shown below. Does anyone know why it doesn't continue to the installation point?
I also noticed that in the code that does work, there's a folder structure in the bin directory that matches the src directory.
src>com.deitel.doodlz
bin>com>deitel>doodlz - contains all the class files
In my project, there is no folder structure like this in my bin directory. Is there something else I need to do besides just hitting the run button? Do I have to do some type of build first? Thanks.

I have got the answer of the Question :
Problem is solved using following below step :
step-1 : go to c:\user\name_of_user\.android\avd\name_of_avd
step-2 : delete below folder
1. userdata-qemu.img.lock
2. cache.img.lock
Run your application , every thing going right but i don't get right solution ,
why this problem is generate.
Thank You

Android app is not launching

i had a working application until i changed the package name in the AndroidManifest.xml. I changed it back, but then i found that i had two files in the gen folder.
I usually (as now) have sg like this:
But that time had something else in my gen folder: just "com.bfarago" as far as i remember and another R.java inside that was complaining about the package name. I deleted this package with the R.java and since then i cannot launch the application.
I exited and restarted eclipse and at the launch its stuck at this point:

Logcat:

Later i will need to recreate the whole app but now i want this to work again.
Please help me..

You can safely delete any R.java and it will regenerate them for you. Try making a new AVD and restarting your computer to fix the second problem .

(I am posting this to close the topic as i first commented this weeks ago)
Thank you guys. Luckily i had the .apk file on my phone so I just copied it to computer and now it's working again.
