Genymotion emulator crashes when logging in

My app crashes when trying to verify username and password from mySQL database (logging in). This is verified on an AsyncTask method. It works fine on the normal Eclipse emulator. Are there any settings or tweaks to be done? Does it crash coz of the AsyncTask, or is there any other factor?
Here's the logcat:

Maybe you already had fixed this issue. but this issue was caused by that you tried to do network operation in the main UI thread and that is not allowed.
The exception log can explain itself.

Running empty Android program - is this behavior expected?

I'm learning the basics of Android development and I've ran into some issues with setting up the programming environment. Now I've created a new Android Application Project and I'm running it using my phone. When I do, I get an error message on my phone: "Unfortunately, HelloWorld has stopped." and I'm not sure if it's supposed to or not, considering that I've done absolutely nothing to the project files. Here is the LogCat output in its entirety:

So, is this normal behavior or have I done something wrong while setting up Eclipse, etc?

It looks like the Android compatibility library is not correctly configured for your project. In Eclipse, right click on the project in the package explorer and select Android Tools > Add Support Library. After setting up the support library, clean and rebuild your project.

This is normal behavior when reporting an error with your application.

Getting warning when trying to view saved camera picture in gridview

I am going to use camera/gallery in my project. FOr this i have first taken picture and saved it in my folder(Suppose pictureworld) and also saved the imageuri in the localdatabase. Then when i am trying to get the picture to show it in the gridview i am getting a warning message. In the gridview there is no picture but it can view the picture name. I have checked that it is creating the picture and also the uri in the localdatabase is correct.I want to add that when i am trying to save the pic using the gallery ..there is no problem. I have used the same adapter for viewing the saved gallery and camera picture. I am attaching the warning here:

Have you given the permission to read the local storage? You should check if any permission is declared in Android Manifest regarding Writing and reading of Internal Storage.

did you add permissions
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
One more thing:
With sdk, you can't write to the root of internal storage. This cause your error.Try something like this
final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

Android http-request causes Error - sitting since 3 days

I am sitting since 3 days, looking everywhere on net but it dosnt work ... every time I try to make a http-request on android: it comes the error: unfourtunately, ... has stopped. here my code:

public class SdsdActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread trd = new Thread(new Runnable(){
public void run(){
// Creating HTTP client
HttpClient httpClient = new DefaultHttpClient();
// Creating HTTP Post
HttpPost httpPost = new HttpPost(

// Building post parameters

List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
nameValuePair.add(new BasicNameValuePair("test", "test"));
nameValuePair.add(new BasicNameValuePair("message",
"Hi, trying Android HTTP post!"));
// Url Encoding the POST parameters
try {
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
} catch (UnsupportedEncodingException e) {
// writing error to Log
e.printStackTrace();
}
// Making HTTP Request
try {
HttpResponse response = httpClient.execute(httpPost);
// writing response to log
Log.d("Http Response:", response.toString());
} catch (ClientProtocolException e) {
// writing exception to log
e.printStackTrace();
} catch (IOException e) {
// writing exception to log

} });
trd.run();
}
}

Maybe I am to stupid but since 3 days I trying to get it running, The Applications starts, but stops after start everytime ...
Permission Internet is done and Firewall is np > WebBrowser in emulator works as well, what is wrong? pls - thank you very much for every answer!

You are executing the run() method of your Thread object on the main thread. Replace this:
trd.run();
with this:
trd.start();

As of Android 3.0, you cannot perform this type of request on the main thread.
NetworkOnMainThreadException
Class Overview
The exception that is thrown when an application attempts to perform a networking operation on its main thread.
This is only thrown for applications targeting the Honeycomb SDK or higher. Applications targeting earlier SDK versions are allowed to do networking on their main event loop threads, but it's heavily discouraged. See the document Designing for Responsiveness.
Also see StrictMode.
See http://developer.android.com/guide/practices/design/responsiveness.html for guidelines on building responsive applications.

From your log, it looks like the error is android.os.NetworkOnMainThreadException. From http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html, it sounds like the error is that you're trying to do network operations in your main thread. Since this can make your UI unresponsive, it's discouraged. And since you seem to be running in strict mode (http://developer.android.com/reference/android/os/StrictMode.html), it's crashing the app.
Also, you should be calling trd.start() instead of trd.run()
