Unfortunately, AndroidFirst has stopped

Question

I am a beginner in android application & just started building first "HelloWorld" app. i followed official tutorial and designed emulator. But when i run it, the emulator says "Unfortunately, AndroidFirst has stopped". I looked around on SO but different solutions didn't help. I am a very beginner for Android, hence can't find the bug or something like wrong/error.

following is logCat:

For that Android Support library is required

See this image:

enter image description here

Then just import the v7 compact library project into your work space and add it as a library to your project

you can find it in sdk\extras\android\support\v7\appcompat where your SDK is present in directory.

After importing, select your project right click ->Properties-> Android->Add->Select app compact

click ok.

The problem resolve when i downloaded API-19 & re-created the AVD. On a very first attempt, the AVD shows "Hello World" the default text on emulator.
