When I change the code and try to lauch the app sometimes this happends:

Aborted
And the app does not lauch unless I rebuild the solution - then it launches fine
This is not that serious but very annoying as it happens once every 3-4 builds
What is wrong?

You probably have and HTC phone (M8 I'd guess) with HTC Sense. There is a bug in their code which prevents you from installing the app sometimes. Here's relevant question and answer from HTCdev FAQ:
Why does my debug APK sometimes fail to install or run on my device
and how to recover?
HTC devices with Lollipop 5.0.0 or 5.0.1 may experience this issue and
we suggest retrying the installation step for workaround. HTC will
prepare the solution to address the issue on Lollipop MR1.
So, nothing you can do but to wait for Android update. Since HTC backed off from pushing Lollipop MR1, you will have to wait for Marshmallow update.

Cannot set up guest memory 'android_arm': Invalid argument

I've spent days trying to launch any Android program. Even "Hello World" gives me the same error:
[2014-10-28 18:07:14 - android19] Android Launch!
[2014-10-28 18:07:14 - android19] adb is running normally.

[2014-10-28 18:07:43 - Emulator] Cannot set up guest memory 'android_arm': Invalid argument
Anyone can help? Thanks much!

Try to reduce RAM size of an emulator
In Eclipse
Window -> Android Virtual Device Manager
Select your device and click Edit button in right part of window
Then in Memory Options secton find RAM parameter and set it to 512 for example. Click OK for saving. Now try to re-debug your app

In Android Studio:
Open Avd manager
Edit the settings for the AVD configuration
Click in the "Show Advanced Settings"
In the "Memory and Storage" section reduce the RAM size

For me, the default RAM size of emulator was 1 GB RAM which was the issue for me in opening the emulator. I reduced RAM size to 512 MB and it works....

In Android Studio:
Open AVD Manager and go to Advanced Settings
Tools > Android > AVD Manager > Your Device > Pencil Icon> Show Advanced Settings > Memory and Storage
Reduce RAM size (512 MB worked for me)
RAM size

In Android Studio:
If you have just updated the studio then you might face this problem.
Try restarting Android Studio. It should solve your problem

If you are facing problem in android studio, just click on show on disk operation
open config file and find for ram word. Edit size to your desired on and restart the studio.
It worked for me.

how to remove emulator starting error

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.

Running applicatiom from eclipse causing phone restart

im using eclipse to develop android app.
Im debugging my app on real device, htc desire hd.
When i start my app from eclipse its allways restart my phone.
This behavior wasnt allways like this and suddenly happaned.
I tried 3 different ROMs all 4.2.2 and its happing in all of them.
In my log cat i dont see any errors except this in my console:
[2013-09-05 21:25:33 - WorkoutLog2] Failed to install WorkoutLog2.apk on device 'HT0BRRX047774!
[2013-09-05 21:25:33 - WorkoutLog2] (null)
[2013-09-05 21:25:33 - WorkoutLog2] Launch failed on device: HT0BRRX047774
Why this is happening?

Android Emulator is not responding to program

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
[2011-03-14 00:11:25 - HelloAndroid] Android Launch!
[2011-03-14 00:11:25 - HelloAndroid] adb is running normally.
[2011-03-14 00:11:25 - HelloAndroid] Performing com.example.helloandroid.HelloAndroid activity launch

[2011-03-14 00:11:30 - HelloAndroid] Waiting for HOME ('android.process.acore') to be launched...
Or if I have the emulator already up, I get this
[2011-03-14 08:23:09 - HelloAndroid] Android Launch!
[2011-03-14 08:23:09 - HelloAndroid] adb is running normally.

[2011-03-14 08:23:27 - HelloAndroid] Starting activity com.example.helloandroid.HelloAndroid on device emulator-5554
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
HelloAndroid] Starting activity com.example.helloandroid.HelloAndroid on device emulator-5554
on you console
click on menu button and try to see output
