Ok Folks I decided to try this developer thing, and after about a dozen tutorials, ended up with the following Hello World type program:
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);}
}
Simple enough, So I go to compile it and I get this

Or if I have the emulator already up, I get this

And then the emulator comes up everytime with just this blank screen, with the text "android" on it. And it sits there for about 3 minutes until it goes to another blank black screen with "android" except its animated. I have looked around and can't seem to find anyone who has the same problem. Its like the emulator does not even recognize anything I am doing. Here is a nice screenshot of the blank nothingness:
So, any ideas what I did wrong?
Try waiting for the emulator to load everything before lunching your app.
That's the startup screen for the emulator... It takes a while to boot the emulator, but once it is up and running, it should fire up your application.
The first typed font is the bootstrapping stage, and then the animated version is when it is loading the OS. The next screen should be your Android platform with a GUI.
I too had the same issue.
The program should be executed only after the emulator is ready to run it. So wen u open eclipse press the run button and wait for some time. This will indirectly start the emulator. Once it is loaded press the run button again, this time to run the program.
I had this issue too. My problem was the SDK version. I installed versions 3.1, 3.2 and 2.2 on my Eclipse and I created 3 different target machines. SDK versions 3.1 and 3.2 did not work whereas version 2.2 did go through. I guess there is no stable emulator for SDK 3.*. If you really need to use such a SDK version you might consider using an actual device. My system: Ubuntu 10.04 running Eclipse 3.5.2.
Hope this helps.
when you open the eclipse then go the run tab and run the emulator and appears the GUI screens in emulator then run the application.and then here after use the same emulator dont close.it take a more time to run the emulator. if your system slow.
Try using Genymotion. You can download a version for Windows/Mac OS X/Linux after registering. A plugin for Eclipse is also avaliable.
i give you link Genymotion Emulator please download and setup.
as per my experience Genymotion Vertual device is faster then android emulator.
after you get result

How to attach back the Android emulator to ADB?
Well I just downloaded everything today to get started programming on android. Files Downloaded: Java JRE and JDK, both latest versions. And ADT Bundle (unzipped in a folder).
In the process running "Myfirstapp" I got stuck trying to launch AVD, no idea why it is not working.
(Device: 2.7" QVGA--Target:Android 4.3 - API level 18--default everything else)
After created the new AVD, I clicked start then the launch windows appears and nothing happened, no error message also.
If I try to run the app directly using "run as: Android Application" i got this on the

Hi guys I just wanted to say that I solved My problem updating my videocard driver(ATI Radeon HD 5450).
On Starting emulator for AVD 'hello' it shows Logcat Error:
emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.
RenderServer::create failed to listen
emulator: emulator window was out of view and was recentered
it seems too many emulator instances are running on this machine. Aborting
It is actually happen when you upgrade your ADT and SDK to the 20th version. For more details Reffer.
I try to understand how works emulator for android.
I use adt bundle (Eclipse).
Yesterday emulator launched with error,
changing ram, heap size, re-creating, restarting allowed to run emulator.
After restarting of computer today - emulator stop run again. The same error 0x3005 - OpenGlES.

To fix the API level warning, check uses-sdk element.
The failure seems to be caused by a disconnected device. Remember that you should allow USB debugging.
Try the steps recommended in the documentation: Eclipse isn't talking to the emulator
Let us know if that works. There are several more things that can be done if that doesn't work.
Please:
Open the SDK manager
Then download the latest APIs and API Tools from here
Then you need to start new AVD using one of the downloaded APIs
