after i tried a lot to fix this problem i figured out that the library res will not compile with project which i don't understand but i just merged all library projects together in new project (like copy all resource value drawable style and everything related).
now its work like a charm! :)

You're calling findViewById() too early, in object initialization phase such as constructor or member variables initialization. You cannot call any activity methods like findViewById() before onCreate(). Move the call to onCreate(). Also place it after setContentView() so you can get a non-null value.

I would recommend you update the ADK's libraries. This question's answer details how to update your libraries.
Furthermore, verify that the libraries you imported for com.google.android.maps have been added to your build path. It seems an off thing to check but working with Android, I have seen many stranger things!
Edit: As stated by one of the comments, the deprecated maps library might be the culprit. If the update does not fix the problem. Try raising the minimum version you are targeting. Legacy support is nice but often induces more problems than it solves. Unless it is of crucial importance to you, I would personally only target the latest release which I believe was API version 14 or 16.

yup as Raghunandan said you are using Google maps API V1 which is deprecated one. Follow this link for Convert it to API V2.
And also you can try this code which I got map on my emulator.

LogCat. How to trace a bug?

I am new to Android debugging. i read about logCat and DDMS on the functions both have and on filtering.
But, i dont understand how to debug my code with logCat. i classified my logcat by Error. and i got 30 errors relating to all kind of issues, ranging from sound issues to battery issues to main issues...

My code in the class is quite simple, i did what the example in Android Orielly book did:

public class StatusActivity2 extends Activity implements OnClickListener{

EditText editText;

Twitter twitter;
/** Called when the activity is first created. */

updateButton.setOnClickListener(this);
textCount= (TextView) findViewById(R.id.editText);
textCount.setText(Integer.toString(40));
textCount.setTextColor(Color.GREEN);
// editText.addTextChangedListener(this);
twitter=new Twitter("student","password");
twitter.setAPIRootUrl(("http://yamba.marakana.com/api"));
//added by me
AsyncTask<String, ?, ?> asyn=new PostToTwitter();
asyn.execute("deliver this to twitter");
}
class PostToTwitter extends AsyncTask<String,Integer, String>

return status.text;
}
catch(TwitterException e)

e.printStackTrace();
return "Failed to post";
}
}

{
super.onProgressUpdate(values);
}
protected void onPostExecute(String result)
{
Toast.makeText(StatusActivity2.this,result,Toast.LENGTH_LONG).show();
}
}
public void onClick(View arg0) {
// TODO Auto-generated method stub
String status=editText.getText().toString();
new PostToTwitter().execute(status);
Log.d(TAG, "onClick");
}
}
i have no red error marks, nor here nor in the main.xml , string.xml files
How do i trace my bug?

You just read through the output to find
Caused by: java.lang.ClassNotFoundException: com.markana.yamba.StatusActivity1
Which means that this class is missing in the .apk that you've deployed to the device.
Note that your activity is named StatusActivity2 - double check the manifest if that has still StatusActivity1.

I got an error during activity start [closed]

java.lang.RuntimeException:
Your content must have a ListView whose id attribute is 'android.R.id.list'
Make sure your view file has a ListView element, with android:id="#android:id/list".
This is how the ListActivity knows where to display the data you're adding.

From http://developer.android.com/reference/android/app/ListActivity.html
ListActivity has a default layout that consists of a single, full-screen list in the center of the screen. However, if you desire, you can customize the screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain a ListView object with the id "#android:id/list" (or list if it's in code)
Check if you have "#android:id/list" in your xml ?
