I've started to write a small app for android. It looks very nice, but there is one thing I don't understand.I've created a new intent in the activity A and I've added a serialized vector intent.putExtra("key", vector).

b = this.getIntent().getExtras();
s = this.getIntent().getStringExtra("DEFAULTTEXT");
public void onClick(View v)
{
String a = "http://152.226.152.156:1010/jsp-examples/test1";
URL url = null;
HttpURLConnection httpurlconnection = null;
try {
url = new URL(a);
httpurlconnection = (HttpURLConnection) url
.openConnection();
httpurlconnection.setDoOutput(true);
httpurlconnection.setRequestMethod("POST");
Toast.makeText(Booking.this, a, Toast.LENGTH_SHORT).show();
Toast.makeText(Booking.this, "Toast1", Toast.LENGTH_SHORT).show();
ObjectOutputStream dos = new ObjectOutputStream(httpurlconnection.getOutputStream());
SendVEctor.add(txtArrivalTime.getText().toString());
SendVEctor.add(txtFerry.getText().toString());
SendVEctor.add(txtStatus.getText().toString());
SendVEctor.add(txtDestination.getText().toString());
SendVEctor.add(s.toString());
dos.writeObject(SendVEctor);
dos.close();
s would be my intent and how would i put it into my SendVEctor?
I have this code: protected void onListItemClick(ListView l, View v, int position, long id)
super.onListItemClick(l, v, position, id);
Log.i(TAG, "The id of the selected note is " + id);
Intent editNote = new Intent(this, TaskEditActivity.class);
editNote.putExtra(TasksDBAdapter.KEY_ID, id);
startActivityForResult(editNote, EDIT_TASK_REQUEST);
}And this code that retrieves the extra FROM A DIFFERENT ACTIVITY: if (savedInstanceState != null) { id = savedInstanceState.getLong(TasksDBAdapter.KEY_ID); Log.i(TAG, "Id of note = " + id);In the first code snippet, Logcat says: The id of the selected note is 2, but in the second code snippet, Logcat says: Id of note = 0. What just happened here? Any solutions to this VERY annoying problem.
Is there any way to put an extra into the intent launched by a shortcut?

View 4 Replies View RelatedI have a service that produces as result a SortedSet object. I need to pass it to another Intent that will use it. First is put in the notification area, then when the user actions it it will need to fire the activity.As it it's own SortedSet is not Parcelable nor Serializable so it won't work. One single item in SortedSet is already parcelable and it's used fine, but I need the whole set.How to pass a SortedSet as an Intent's extra?
View 1 Replies View RelatedI have a program that sends a broadcast Intent that needs an "extra" value.The value is declared as being of type Object[], though I know that the elements are always of type Integer or String.That's part of an API not under my control. What's the most concise and/or efficient way to do the equivalent of the putExtra call below?

How would i put a vector into my array_spinner?
Does the current API support scalable vector graphics? If so which file formats? If not, will it be added in the future? I ask because I'd like my animations to based off of SVGs - in order to better support different screen resolutions while reducing file size.
View 2 Replies View RelatedI need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ So i bet there is a simple solution how to recall the values of sensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me. Code...

View 2 Replies View RelatedI need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?

View 1 Replies View RelatedI'm am working on a basic augmented reality application on Android. What I did so far is detect a square with opencv and then using cvFindExtrinsicCameraParams2() I calculated a rotation and translation vector. For this I used 4 object points, which are just the corners of a square around (0,0,0) and the 4 corners of the square in the image.
This yields me a pretty good rotation and translation matrix. I also calculated the rotation matrix with cvRodrigues2() since using this is easier than the rotation vector. As long as I use these to draw some points in the image everything works fine. My next step is however to pass these vectors and the matrix back to java and then use them with OpenGL to draw a square in an OpenGLView. The square should be exactly around the square in the image which is displayed behind the OpenGLView.
My problem is that I cannot find the correct way of using the rotation matrix and translation vector in OpenGL. I started of with exactly the same object points as used for the openCV functions. Then I applied the rotation matrix and translation vector in pretty much any possible way I could think of. Sadly none of these approaches produce a result which is anyway near what I hoped for. So my question is can anyone tell me how to use them correctly?
So far the "closest" results I have gotten, was when randomly multiplying the whole matrix with -1. But most of the time the squares still look mirror inverted or rotated for 180 degrees. So I guess it was just a lucky hit, but not the right approach.
For an application I am working on, I need to display custom raster image tiles (not vector based, probably from satellite imagery), and I need to do so offline. I would like to use the MapView, but I cannot see a way to tell it to use custom, offline map tiles instead of pulling down data from google's servers.
I've seen a few alternatives, but none seem appropriate to my need MapDroyd Seems to only support vector-based maps. mapdroyd.com/ OSMDroid Appears to use Open Street Maps; I don't see any documentation anywhere stating that you can use custom map tiles. code.google.com/p/osmdroid/ There was a third alternative, but my post got eaten and I can't find it in my history. Am I going to have to bite the bullet and 'roll my own'?
Is it possible to add extra languages to Android? My current Android phone only supports English and Chinese language input. I would like to have Dutch also, as I can use it for word completion. The question on top of that is, how to switch easily between these languages in the text input (keyboard) GUI?

I've built a widget that uses a LinearLayout and I've put two TextViews in the layout.
The gravity of the layout is "top".
The problem is that I get a space between the two TextViews and I can't get rid of it.
CODE:....................
As you can see I tried putting padding 0 and verticalSpacing 0 but I still get a space between them.
When I created a button view, Android always create some extra space between this button and other views below it.
In this example below, there is a button above the second button. You can see the gap between these two buttons. How can I get rid of this gap?

View 2 Replies View RelatedI'm trying to pass an object from an activity to another activity. In the first activity i do:
Intent intent = new Intent(this, SecondsActivity.class); intent.putExtra("package.class", SerializableObject);
And in the second activity:
Class object = (Class) extras.getSerializable("package.class"); objetc.modifySomething(2432);
Intent intent = new Intent(this, ThirdActivity.class); intent.putExtra("package.class", SerializableObject);
But if i modify the object in the second activity, it fails when i send this object to a third activity.Why does it fail? What am i doing wrong? I just need to pass objects between diferent activities because i have an object which contains many information, and creating a Boundle would be very big and ugly in my code.
The product I have in mind is a Android phone with 32 GB of internal storage, plus the usual microSD expansion slot.
