[android-developers] '-1' error during HTTPS communication.

[ABhi]

Hi All,

Below is my problem scenario.

 - My Server is on running on https.
 - Doing connection with ‘HttpURLConnection’ api & already tried
‘HttpClient’ as well earlier but both are showing same issue.
 - Server certificate is ‘Verisign Class
   3’ certificate.
 - Every alternate request sent to
   server, receives ‘-1’ in http
   response code. For e.g. If my first
   request is successful (200 code)
   second request would get (-1) code,
   then again successful & then again
   4th request gets -1 in response.  I’m
   not sure why this -1 code is returned
   & there’s not description on HTTP
   standard site as well.

Any idea how can i get rid off this '-1' response i receive. In which
scenario server returns this code?

I'm posting my sample code below.

--
HttpURLConnection connection;
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, new TrustManager[] { new TrustManager() },
new SecureRandom());

HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(new
MyHostnameVerifier());
connection = (HttpsURLConnection) httpUrl.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Length", String
.valueOf(requestBinary.length));
connection.setRequestProperty("Content-Type",
"octet/x-application-csam");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setConnectTimeout(3);
connection.connect();
connection.getOutputStream().write(requestBinary);
int responseCode = connection.getResponseCode();

Thanks in advance

[android-developers] Curved Gallery view

[Abhi]

Hi all,

I would like to know if it is possible to create a curved gallery view
from the default horizontal one that Android offers? I don't know if
that entails changing the Gallery code in Android framework which I
want to avoid. Is there any other way to make a custom Gallery view
from scratch? Again, how to go about doing that?

Thanks. Any help would be appreciated.

[android-developers] display images in galleryview from sqlite database

[Abhi]

Hi

I have a sqlite database that has over 2000 low res thumbnails of
pictures. The database itself is over 100MB in size. The project
requires me to have the photos residing in the database instead of the
file path. This is what I would like to do and need help with as this
is my first time dealing with images. I have a horizontal GalleryView
in my App UI that I want to populate with images pulled from this
database dynamically. I don't mind if these images are lazy loaded on
to the gallery view in the background. I read somewhere that I will
have to use an ImageAdapter to bind the images to the UI element
dynamically. I need in understanding how this is done. I have never
used the BaseAdapter class.

Thanks,

AB

[android-developers] how to deflate/hide(invisible) ViewStub from Menu (onOptionsItemSelected)?

[Abhi]

I keep getting NullPointerException trying to deflate or make
invisible the ViewStub from my UI. I just wanted to be sure I am doing
it right.

I am inflating my ViewStub in onItemLongClick method of GalleryView by
doing the following:

@Override
public boolean onItemLongClick(AdapterView arg0, View
viu, int arg2,
long arg3) {
Toast.makeText(GalleryView.this, "New item added to
Favorites", Toast.LENGTH_SHORT).show();


favsCount++;

   //checking to see if ViewStub is already inflated or
not
if(!stubvis){
stub = (ViewStub) findViewById(R.id.stub1);
stub.inflate();
stubvis = true;
trayUP = true;
}

return true;
}

});

and then in onPrepareOptionsMenu() I am adding the menu item based on
the visibility of ViewStub. If inflated and visible, I create a menu
item to hide it, otherwise, a menu item to show/make visible.

@Override

public boolean onPrepareOptionsMenu(Menu menu) {

menu.clear();


if(trayUP) {

menu.add(0, HIDETRAY, 0, "Hide Favorites Tray");

} else {

menu.add(0, SHOWTRAY, 0, "Show Favorites Tray");

}

return super.onPrepareOptionsMenu(menu);

}
Next, in onOptionsItemSelected(), I am writing the two cases based on
the menu item selection. Case 1 when the tray is not visible, so I
make it visible. Case 2 when it is visible, so I hide it by doing the
following:

@Override
public boolean onOptionsItemSelected(MenuItem item) {

switch (item.getItemId()) {

case HIDETRAY:

Log.v(TAG, "Hiding Favs Tray");
findViewById(R.id.stub1).setVisibility(View.GONE);
trayUP = false;

case SHOWTRAY:

Log.v(TAG, "Showing Favs Tray");
findViewById(R.id.stub1).setVisibility(View.VISIBLE);
trayUP = true;

}

return true;
}

I know I am making a silly mistake somewhere. And my mind is too
saturated to think straight at the moment. Need help :(

Thanks,

Ab

[android-developers] Re: how to deflate/hide(invisible) ViewStub from Menu (onOptionsItemSelected)?

[Abhi]

Hi Kostya,

I have a GalleryView in my ViewStub and I dynamically add images to
the Gallery. I would like to control from a menu option, the
visibility of the complete ViewStub view. So basically, when the
ViewStub is up displaying the gallery and I press the menu option, the
whole view gets hidden but the content (i.e. Gallery items) remain in
the stub. On pressing menu option again, the whole view is displayed
again with the gallery items selected earlier.

I don't know what you mean by replacing the stub with  and
toggle its contents' visibility. Could you elaborate a little more?

Thanks,

Abhi

[android-developers] how to retrieve images from a sql database?

[Abhi]

Hi

I have a database of low res images that I am trying to use for one of
my applications. What I would like to do is to retrieve the images one
by one and display them in a slideshow. I was told that images are
stored as byte arrays in sql database. I am new to sql and looking for
some direction on how to do this, what query to put and how to extract
the byte array from the database for further use.

Any help appreciated.

Thanks,
AB

Well, that's an option I don't have at the moment. I have a pre-

[Abhi]

@Ibendlin - Yes, SQLite on device is what I meant. Sorry about the
confusion
@Drezden - I somehow don't have that option to add images to
MediaStore, keeping the file path in the SQLite database. I would like
to still try retrieving those images stored in the database before
deciding which way to really go. Anything you could tell me about
doing that?

Thanks,

AB

The field type for image column is BLOB. And I have no idea what that
means. I am trying to figure out a way to retreive BLOB data into my
Android application and display it on the screen.

[android-developers] NullPointerException on displaying ImageView of a bitmap

[Abhi]

Hi

I have the following piece of code which is resulting in a
NullPointerException and I am not able to understand why. I am able to
get the correct size of the bitmap in the Log statement below before
displaying the image, so up to that point everything is good.

//result is a byte array which contains the jpeg image

ByteArrayInputStream inputStream = new ByteArrayInputStream(result);
b = BitmapFactory.decodeStream(inputStream);

Log.i(TAG, "Size of bitmap is " + b.getWidth() + " x " +
b.getHeight());

ImageView imageview1 = (ImageView) findViewById(R.id.ImageV);
imageview1.setImageBitmap(b);

The exception I am getting is below :

[android-developers] Gallery View and SQLite database

[Abhi]

Hi all,

I have a sqlite database of 100+ low res images saved as Blob data. I
am creating an App that has a GalleryView and I would like to display
the 100+ images from my database in this view. The user can scroll
through the horizontally scrolling list and select the one he wants to
see full screen.

I am using a sample app that takes sample images from 'res/drawable'
folder to display them on the gallery view. I would like to do the
same but pull images from the database instead. Can someone guide me?

Thanks,

AB

[android-developers] unable to write to sdcard and the permission is not set

[Abhi Rao]

Android 2.2 using the emulator
I am unable to read and write sdcard

When I do ls -l after adb shell - this is what I see
# ls -l
ls -l
drwxr-xr-x root system2010-12-27 05:24 asec
drwx-- root root  2010-12-27 05:24 secure
d- system   system2010-12-27 05:24 sdcard
#

Here is how I prepared the SDCARD
- Run mksdcard 8192K C:\android-dev\emu_sdcard\emu_logFile
- Create a new AVD, then assign emu_logFile to it so that when I view
the AVD Details it says C:\android-dev\emu_sdcard\emu_logFile against
the field "SD Card"

In the code, sdDir.canWrite returns false - please note it is not the
exception.

I have added the following to AndroidManifest.xml
**uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" **

I have posted this in stackoverflow - I have gone through the postings
related to sdcard and emulator - no success yet!

Please help -
