From the JavaDoc, the EXTRA_STREAM parameter when launching an intent needs to be an URI. How can I pass a Bitmap object which I get from launching a "android.provider.MediaStore.ACTION_IMAGE_CAPTURE" intent? code...

I'm using eclipse to develop over android, i'm trying to connect to a .net webservice...when i'm calling a webmethod with no parameters it works fine... but when i come to pass a parameter to the webmethod things turn upside down... the parameter is passed as null (while debugging the webservice i discovered that) and i get a null from the webmethod in the client side code... i've been searching for a solution for a day now and all that i can interpreter is that people keep talking about encoding styles and such stuff.... i've tried it all but in vain. i'm using ksoap2 version 2.3 with the following code:

I try to save a unique image to each object but I get this error, how should the constructor look for it to work that way? The constructor Beer(String, int, int) is undefined

final Beer b2 = new Beer("Carlsberg", 7, R.drawable.carlsberg);

How to pass a parameter to an application that I call from my Application?
View 1 Replies View RelatedI'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?
I have this code: Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); startActivity(intent);

But how can i attach a Bitmap object when launching the intent?
I have read http://developer.android.com/reference/android/content/Intent.html, the closet thing to what i need is EXTRA_STREAM, like this: intent2.putExtra(Intent.EXTRA_STREAM, _uri);
but my case, I have a reference of Bitmap object, not an URI of an Bitmap.
Please tell me what can I do to attach a Bitmap object?

I know this has been asked a lot of times in StackOverflow already, but I haven't quite found a solution yet. My app sends an email with a link in it that when clicked should launch the app. According to @hackbod, the best way to do it is to make use of the Intent URI (see this). Here's my code that sets the intent and puts it in the email body: Code...

View 2 Replies View RelatedI've got two activities, one of them is called MyActivity. I want both of them to be able to use a function located in a class othat we may call MyClass. In MyClass, I try to use an intent to launch the activity AnotherActivity. Since the constructor takes a context as parameter, I simply tried to store a context from the activity in the constructor, and then use it when I try to create my intent.However, even thought none of the arguments are null (checked that with a simple if-statement), intent seems to be null and a NullPointerException is thrown. Why does it not work, and what can I do to solve the problem?

View 1 Replies View RelatedFirst of all let me say that this questions is slightly connected to another question by me. Actually it was created because of that. I have the following code to write a bitmap downloaded from the net to a file in the sd card:
// Get image from url
URL u = new URL(url);
HttpGet httpRequest = new HttpGet(u.toURI());
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity);
InputStream instream = bufHttpEntity.getContent();
Bitmap bmImg = BitmapFactory.decodeStream(instream);
instream.close();
// Write image to a file in sd card
File posterFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Android/data/com.myapp/files/image.jpg");
posterFile.createNewFile();
BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(posterFile));
Bitmap mutable = Bitmap.createScaledBitmap(bmImg,bmImg.getWidth(),bmImg.getHeight(),true);
mutable.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
// Launch default viewer for the file
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(posterFile.getAbsolutePath()),"image/*");
((Activity) getContext()).startActivity(intent);
A few notes. I am creating the "mutable" bitmap after seeing someone using it and it seems to work better than without it. And I am using the parse method on the Uri class and not the fromFile because in my code I am calling these in different places and when I am creating the intent I have a string path instead of a file. Now for my problem. The file gets created. The intent launches a dialog asking me to select a viewer. I have 3 viewers installed. The Astro image viewer, the default media gallery (I have a milstone on 2.1 but on the milestone the 2.1 update did not include the 3d gallery so it's the old one) and the 3d gallery from the nexus one (I found the apk in the wild). Now when I launch the 3 viewers the following happen:
Astro image viewer: The activity launches but I see nothing but a black screen.
Media Gallery: I get an exception dialog shown "The application MediaGallery (process com.motorola.gallery) has stoppedunexpectedly. Please try again" with a force close option.
3D gallery: Everything works as it should.
When I try to simply open the file using the Astro file manager (browse to it and simply click) I get the same option dialog but this time things are different:
Astro image viewer: Everything works as it should.
Media Gallery: Everything works as it should.
3D gallery: The activity launches but I see nothing but a black screen.
As you can see everything is a complete mess. I have no idea why this happens but it happens like this every single time. It's not a random bug. Am I missing something when I am creating the intent? Or when I am creating the image file? As noted in the comment here is the part of interest in adb logcat. Also I should note that I changed the way I create the image file. Since I want to create a file that reflects an online file I simply download it instead of creating a Bitmap and then creating the file (this was done because at some point I needed the Bitmap but now I do it the other way around). The problems persist thought and are exactly the same:

I've got a problem My app show a first layout like: Gridview1 (3 images in 1 row) ImageView1 (1 image) Gridview2 (3 images in 1 row) ImgaeView2 (1 image) Gridview3 (3 images in 1 row) ImgaeView3 (1 image) When you clik over an image it will be open full screen in a second layout, The problem was that I don't know how to pass the image to the new intent. Now I've the next code:
public AdapterView.OnItemClickListener pulsarImagen = new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { Intent intent = new Intent(GridViewer.this , GalleryViewer.class); intent.putExtra("id", arg0.getItemIdAtPosition (arg2)); startActivity(intent); //finish(); } };
But the ItemID is always 0. Before I've only one gridview and then I passed the item's position. But now I've 3 different gridviews and I don't know if the position of item selecte it's from gridview 1,2 or 3. I supose that the great solutin it will be to pass the id resource (image) but I don't know how to pass it. Can you help me?

I have a service that produces as result a SortedSet object. I need to pass it to another Intent that will use it.
