When I'm creating object to write to output stream (size is lower than 150KB) it probably gets instantly destroyed, because of:
System.out.println("Sending object..");
Packet p = new Packet(mJpegData); // here exists
System.out.println(p); // reference exists
oos.writeObject(p); // null exception error

Why GS is removing my object? I've got in about 120 MB free memory.
How to fix it?
I think the problem is with oos because it might be the one causing NullPointerException.
Change your code a little as below:
System.out.println("Sending object..");
Packet p = new Packet(mJpegData); // here exists
System.out.println(p); // reference exists
if(oos != null)
oos.writeObject(p);
else
Log.w("oos", "its null");

you will see that a NullPointerException is thrown in line 16 of your activity firstl.
Please post your code of the firstl activity if you need more help on that.
as after seeing your logcat these maybe possible
CASE 1: make sure you are setting right layout:
public class firstl extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// The activity is being created.
setContentView(R.layout.main);//MAKE SURE YOU ARE SETTING RIGHT LAYOUT
}
CASE 2: make sure you are using right id for views accessing in code as define in xml layout
CASE 3: make sure you are registering Activity with right name in Manifest.xml :
<Activity android:name=".firstl" />
recently while reading some tutorials online, I saw this video suggesting that the Android SDK now supports OpenGL ES 2.0:
http://www.youtube.com/watch?feature=player_embedded&v=T--vFtyZvc4
Enthusiastically, I added the option for 'GPU Emulation' in my emulator and tried to run a basic HelloOpenGLES20 app, however I was greeted with this error, and some null pointer exceptions which doesn't make sense:
Sorry!
The application
LessonOneActivity (process
lesson.One has stopped
unexpectedly. Please try again.
Force close
The app runs fine on a real Android phone displaying some spinning triangles, I'm wondering if anyone has encountered the problem I'm facing, I've did a fair share of googling but could find no solutions =(

I have run the code, and the exception is due to the fact that the emulator still does not support GLES20. If you print more information, you'll see that supportsEs2 is false.
Why the emulator does not support GLES20 even if GPU Emulation is set to true is system-dependent. If you are developing on Linux, it may be related to the graphics card. Here is a similar question with some possible solutions. At least you can try it.
EDIT:
According to the official site, you need to set your emulator target to API 15 (rev03) or higher.
I'm currently try to run some opencv filters (i.e find egde, Median, ...) on images which are stored in the image gallery folder.
But I get error for loading image. My device is galaxy tab 10.1 with android 3.2, my opencv - API level 8.
I have the following source on a Button:
#Override
public void onClick(View v) {
Bitmap myBitmap = BitmapFactory.decodeFile("/sdcard/image1.jpg");
Bitmap myBitmap32 = myBitmap.copy(Bitmap.Config.ARGB_8888, true);
Mat pic1 = Utils.bitmapToMat(myBitmap32);
}

Thank you.
The openCV library is not attached to your application. Please do the following (i assume that the openCV library is imported to your workspace). On Package Explorer > Right click on the application project > properties > under Library click Add > select openCV Be sure that on Java Build Path you don't have anything related to openCV
I'm designing an application that allows the user to retrieve his data from the server, I'm furnishing this using two different activities, the first one receives the username as a text input and the second one displays the user's data based on the username. I'm using JSON schema for storing and retrieving the data. The app works fine for the first time but when I logout from the second screen using finish() and try to re-enter a new username in the first screen "the app force closes". This has been giving me sleepless nights, want to be overwhelmed with your support.

Apparently, you're trying to access an object in an ArrayList at in your Menus.java file at line 309. You're trying to access the object with the index of 2, but the total ArrayList size is only 2, meaning the highest index would be 1. This causes an IndexOutOfBounds exception as shown here:
ComponentInfo{com.bombil.kustomizer/com.bombil.kustomizer.Menus}:
java.lang.IndexOutOfBoundsException: Invalid index 2, size is 2
E/AndroidRuntime(553): at com.bombil.kustomizer.Menus.AddEditText(Menus.java:309)
Do you have any objects that are being used by both activities? I know I saw this issue once with a project. One of the activities was messing up the HTTPClient object for the other activity. If you are getting a null exception being thrown try and find the variable. If it is a shared resource for both activities then just make sure to deal with it in a clean way when you exit the second activity.
I have 2 activities. First activity extends Activity and second extends ListActivity.
I need to call ListActivity from the Activity class
I have tried the following.
Intent intent = new Intent(firstclassname.this, secongclassname.class);
startActivity(intent);
I've added an entry in the manifest file but it doen't work.
That same code works for the Activity class (if the second class extends ListActivity)
I got following Logcat output

What am I doing wrong?
Your activity is properly started.
The problem is in ArrayAdapter that you are using. You are not providing the resource id of the TextView.
Check out which constructor you are using and provide the correct parameters.
