I'm brand new to development.
I've installed Eclipse and Andoid SDK. But, I can't get emulator to work. I've tried the sample notepad code and Hello Android tutorial code. Each time I try to run either app it just hangs on clock screen (screen also says charging 50% and has a padlock).
Here is the console info for the sample notepad app.

Then nothing...
I've tried the following steps already from this page, but still not working.

Eclipse isn't talking to the emulator
When communication doesn't seem to be happening between Eclipse and the emulator, symptoms can include: nothing happening when you press run, the emulator hanging waiting for a debugger to connect, or errors that Eclipse reports about not being able to find the emulator or shell. By far the most common symptom is that when you press run, the emulator starts (or is already running), but the application doesn't start.
You may find any of these steps will fix the problem and with practice you probably can figure out which one you need to do for your particular issue, but to start with, the safest option is to run through all of them in order:
- Quit the emulator if it is running
- Check that any emulator processes are killed (sometimes they can hang, use ps on unix or mac, or task manager in the process view on windows).
- Quit Eclipse From the command line, type: adb kill-server, start Eclipse and try again
Wondering if I need to try uninstalling and reinstalling some component?
I'm running Windows 7.
Any help much appreciated - in as plain english language as possible please :-)
Are you at the unlock screen? Did you unlock the "phone" You need to drag the unlock button with your mouse by clicking on the button and then dragging to the right
Since you are new to development pls try the following step
- Restart Eclipse
- Open the Android SDK and AVD Manager
- Delete your existing AVD
- Recreate the AVD with your set of paramaters (i.e. name, android version etc)
- Go back to your code and run the program again.
You should now be able to run the sample programs again..
Hope it helps

Setting eclipse, adb and emulator to high priority (it wouldn't let me set it to real time), restarting eclipse, and deleting the emulator and creating a new one actually made the emulator start working for me. Thanks.
Just click on the power button once (it's on the right side). Now try to drag the unlock button on the screen and it should work.
It seems that the ,memory resources are inadequate for running emulator. One thing you can do is that when the emulator hangs for the first time, just close it and then restart it. After this go to Task Manager and set the emulator and adb priority to real time.
