What’s the problem?

After boot into Ubuntu 14.04, you enter your credential and the system just hangs up, freezes. If you are lucky, you might see mouse cursor, background wallpaper but nothing else.

#Missing Icon/Item AVD and SDK manager on eclipse? don't panic actually it's hidden, how to show it? 

#Let's do this:

- Window > Customize Perspective... (you will see Android and AVD Manager are disabled)

- Command Groups Availability > Android and AVD Manager > check

- Tool Bar Visibility > Android and AVD Manager > check

Are you sure you imported android.widget.Spinner and not something else named the same thing? Maybe try the following, just to be sure, change your error line to :

android.widget.Spinner s = (android.widget.Spinner) findViewById(R.id.spinner);

If it doesn't give you a problem there then odds are high that you have a namespace problem.

added this line on your field layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

/*Type conflict.

Your Activity can't have name GridView, because it conflicts with android.widget.GridView. Compiler thinks that you want to cast to GridView extending Activity, not the widget class.

Solutions:

rename you GridView
use fully qualified type here: */

android.widget.GridView gridview = (android.widget.GridView) findViewById(R.id.gridview);

it's just simple solution to take screenshot android emulator from terminal.
adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png

made easy with create bash
alias screenshot="adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > ~/creatorb/android_screenshot.png"

When you can't find command adb, surely your adb path is correct.
