[android-developers] Re: Image scaling on Sony Ericsson Xperia phone

[anon ymous]

Hi Mr Johan, 

I am developing a chat app for my final year project.
So what I am doing is that the image on the sender's phone is being scaled 
down to 20 by 20 sp.
When it reaches the destination i want that image to be scaled up to 100 by 
100 sp.
I had downloaded the code provided 
from 
https://developer.sonymobile.com/2011/06/27/how-to-scale-images-for-your-android-application/
But unfortunately the scaling doesn't work. The images I am saving to the 
database are very very blurry. 
I am using the fit method, not crop.
I am not sure what I am doing wrong. I have been trying to fix my problem 
for the past 3 weeks but its not working.
Please help me. Thank you.

[android-developers] Re: Image is being oriented differently once uploaded to server, why?

[Doug Gordon]

I've seen this happen in a number of places when uploading images. The 
basic issue is that there are two ways to save a rotated image: save the 
raster data in the correct orientation and without metadata, or save the 
raster data in its native orientation and set the metadata value to 
indicate the desired rotation. The problem is that some software 
implementations still do not look at the metadata field and just display 
the raw raster image. So the photo may appear rotated correctly in one 
place and not rotated in another!

 Also when the user is presented the thumbnail, it also shows correct, but

 Im using ftp to upload the image with this code:

 }

 }

 I even changed my logic to this and still nothing, the image is always 
 uploaded in landscape. Even though the thumbnail and stored image on the

[android-developers] Re: Image is being oriented differently once uploaded to server, why?

[Dan Cha]

Can someone tell me if this line in the code actually rewrites the image 
with the new settings or is this merely in memory and not touching the 
original image.. 

It would be great to fix the orientation and resize the image before being 
stored, so that the upload image is already the appropriate file size.

You can scroll top image in horizontal, by using Scrollview Horizontal, if 
there is multiple image at top.

[android-developers] Re: Image captured from my app is rotated by default

[Doug Gordon]

This may not be related to your problem, but I believe that there are 
basically two ways that the orientation of a JPEG photo is determined. One 
is simply by the way the actual data in the file is laid out; for example, 
whether it is stored as 1024x768 or 768x1024. The other determinate is an 
(optional) datum in the file's metadata that specifies camera 
orientation and indicates the degrees of rotation. So even if a photo's 
data is stored as 1024x768, if the orientation data is +90, then it is to 
be displayed rotated to the right in 768x1024 format.

The problem that I've found is that not all devices or image 
processing/display software seems to use the metadata and, making things 
worse, may not propagate the data when saving a modified image. So I've had 
photos from my phone that I've had to rotate in image software to make them 
look right on my PC, but then I'll do something like upload them to 
Facebook and they're rotated the wrong way!

I might be wrong about this, but it's what I've concluded after playing 
around with various devices and image processing programs.

[android-developers] Re: Image captured from my app is rotated by default

[Nobu Games]

This is expected behavior, and Doug's assumption is right. JPEG images may 
contain EXIF http://en.wikipedia.org/wiki/Exchangeable_image_file_formatdata 
blocks that also specify the orientation of the image. On your server 
you need to read the orientation data and use it to rotate the image into 
the opposite direction. If your server code is written in PHP you can use 
the Imagick library and the following functions for determining the 
orientation and rotating the image 
respectively:Imagick::getImageOrientation()http://www.php.net/manual/en/imagick.getimageorientation.php,
 
Imagick::rotateImage()http://www.php.net/manual/en/imagick.rotateimage.php
.
If the server software is written in Java you could use a library such as 
Metadata-Extractor http://code.google.com/p/metadata-extractor/ for 
reading the orientation and any image processing library of your choice for 
rotating the image.

[android-developers] Re: Image to Video Converter In android

[bobbybrend]

Videos are encoded in many different formats for different devices and it 
is necessary to convert your videos to a format compatible with the Android 
operating system. Professional video conversion applications are expensive, 
but there are many free programs available for Macintosh and Windows 
operating systems that can convert your videos to play on Android mobile 
devices.

[android-developers] Re: image issue while view it as base64 in android mobile2.3

[senthil kumar]

Store the image as base64 in sqlite browser but we are not able to see the 
5 or 6 image.
In samasung galaxy y we only see  2 image which we store.In Lemon mobile we 
only see 2 or 4 images.
In micromax only to see 5 or 6 image after that all image we took is seen 
as black screen we don't know why it happening..

[bob]

 

I would try storing the image as a BLOB instead of base64.


Thanks.

[android-developers] Re: Image background (not 9-patch) for an AppWidget

[Mário César Mancinelli de Araújo]

I created a file digital_clock_background.xml (inside res/drawable) and put 
this code:

?xml version=1.0 encoding=utf-8?
shape xmlns:android=http://schemas.android.com/apk/res/android;
android:padding=10dp
android:shape=rectangle 

solid android:color=#00 /

stroke
android:width=2dp
android:color=#00 /

padding
android:bottom=1dp
android:left=1dp
android:right=1dp
android:top=1dp /

corners android:radius=10dp /

/shape

So my AppWidget layout is basically:

?xml version=1.0 encoding=utf-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@+id/rllWidgetBigger
android:layout_width=match_parent
android:layout_height=match_parent
android:layout_margin=@dimen/widget_margin
android:background=@drawable/digital_clock_background 

ImageView
android:id=@+id/imgBackGroundBigger
android:layout_width=fill_parent
android:layout_height=fill_parent
android:layout_alignParentBottom=true
android:layout_alignParentLeft=true
android:layout_alignParentRight=true
android:layout_alignParentTop=true
android:contentDescription=@string/app_name
android:scaleType=centerCrop
android:src=@drawable/digital_andromeda_galaxy_m31 /

/RelativeLayout

And, well, the RelativeLayout now have rounded corners, but the ImageView 
doesn't. And it's corners are coming out of the RelativeLayout...

Is there anyway to correct it (without putting more padding)?

Thanks!

Re: [android-developers] Re: Image background (not 9-patch) for an AppWidget

[vinay kumar]

Hi,

They are number of solution available online but one of them is to recreate
a your bitmap with rounded corners.


public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int pixels) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap
.getHeight(), Config.ARGB_);
Canvas canvas = new Canvas(output);

final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(),
bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = pixels;

paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);

return output;
}


Hope this helps!

Re: [android-developers] Re: Image background (not 9-patch) for an AppWidget

[Mário César Mancinelli de Araújo]

Not really... First of all, how do I discover the value of pixels?
Because it depends on the Android version, on the manufacture of the
equipament... And, most important, I don't have access to the ImageView (I
can set properties, but not get because of the RemoteViews).

Other thing is that the format (if it is a rectangle or a square) will
depend on the AppWidget's minHeight and minWidth. And the images are square
and I set scale type to center crop.

So... I really don't know if it's possible to solve the problem like this.
:/

But thanks anyway. ;)

[android-developers] Re: image view on Customized dialog box

[Piren]

not sure why you're using the .Show() method, its best to use 
onCreateDialog for custom dialogs as well.

but either way, ASyncTasks dont run onPostExecute on the UI thread 
automatically, the run it on the thread the ASyncTask was created in.
To avoid your issue either add a Handler to run the onPostExecute code on 
or try and using  runOnUiThread

Hi Farhan

I guess, the application that you want to create is already present in the
new android version 4.0 (ICS). this effect is known as live effects and
this effect works for both still capture and video record. Please check *Live
Effects* on android site.

Thanks and Regards

It may be present, but I would like to learn how to apply the same or

 Dear Arun,

 First you need to convert Image to YUV format using Image Decoder.
 Then you can feed each YUV Image as a Video Input to Media Recorder Engine.

 Go through the Media Recorder Source Code to get more info.

[android-developers] Re: Image loading in Gridview

Try AsyncTask? You can have doInBackground downloading the images,
then call publishProgress for each image completed, and have
onProgressUpdate update the gridview. You should have no problem
finding tutorials on how to use AsyncTask with a quick search.

 Hi,

 I would like to display an image from external storage which is 72x72
 px.
 My device has high density.
 The image view height and width are wrap_content.

 I got different results if I load the image or use an URL.

 If I use an URL like this then the result will be about 48x48px.

                 imageView.setImageURI(Uri.fromFile(file));

 If I load the bitmap the result is 72x72 px as expected:

                 InputStream is =
 context.getContentResolver().openInputStream(Uri.fromFile(file));
                 Bitmap b = BitmapFactory.decodeStream(is, null, null);
                 is.close();

                 iv2.setImageBitmap(b);

 You can see the results here:

 http://dl.dropbox.com/u/51679071/share/facebook.png

 It would be better if I could use the setImageURI and not to preload
 the image
 and I would like to display the image in appwidgets too.

 Can you tell me what cause the difference and how can I avoid it?

 Thanks,
 Tamas

[android-developers] Re: Image comparison problem: getPixel() in android and getRGB() in JDK return different values for the same image

[Ergen]

Thanks.
I've thought about it. And I tried to change the format _after_
loading the image.
I created a new image IMG2 with new BufferedImage(width, hight,
IMAGE_TYPE) and copied old image (also IMG1)  into the new image
as IMG2.createGraphics().drawRenderedImage(IMG1,null)
Then i've tested all the formats in Java2D  (all constans of
IMAGE_TYPE). All in vain.

 Also, f I remember correctly, Java2D can apply color
 profiles when loading a bitmap.

That would be perfect. But I found no method to make it.
I'll try it again in the evening...

[android-developers] Re: Image Quality problems using Canvas and canvas.scale(Scale, Scale);

[JamesColeman]

Thank you for your reply, I appreciate the input!

Overall I agree with what you are saying about the bleeding
obvious.  However, I down scaled the exact same images on
BlackBerry's and had no problems whatsoever.  In our graphics arts, I
downscale graphics all the time and end up with great looking images.
The problem I am experiencing is something particular to Android
Canvas scale and is similar to the problem in the link I posted.

In intend to have a pinch zoom control the canvas scale so it looks
like I have a challenge ahead of me. One would think if I can pull it
off on a BlackBerry I could do it on an Android somehow.  I hope I am
not stuck with it as you say.

 make it fit. Which gives you a not so great result.

 You have gone to great lengths to avoid scaling when you read it in
 (using Bitmap Factory Options), this is largely a waste of time if you
 scale it for writing using canvas.scale. You will still get scaling
 artefacts on write. You need to suppress scaling for read *and* write.

 The only way that I know of to get pinsharp graphics - with your
 bitmaps appearing exactly how you intended - is to write to a canvas
 which has the same resolution as the actual device (or View). The
 downside of this is that you have to manage all possible screen
 resolutions within your code, as you can no longer use the system to
 map a fixed co-ordinate space in your code to the specs of the actual
 screen. A pretty obvious trade-off between coding simplicity and image
 quality.

 If you are already relying on automatic output scaling for lots of
 other stuff in your code, you are probably stuck with it.

[android-developers] Re: image to text android OCR help?

[Nikolay]

There are Java APIs which wrap calls for native interfaces, for
example, for one of the most popular opensource OCR engines -
Tesseract (http://groups.google.com/group/tesseract-ocr/) - there are
some Java wrappers like tesjeract (http://code.google.com/p/
tesjeract/) or Tess4J (http://tess4j.sf.net/).

One more solution could be a cloud service. It requires end-user
application to have the internet connection, but it's independent from
your programming language choice and resources limitations. Have a
look at ABBYY Cloud OCR SDK (http://www.ocrsdk.com/), it's a cloud-
based OCR SDK recently launched by ABBYY. It's in beta, so for now
it's totally free to use and it has a ready-to-go Android code
samples: https://github.com/abbyysdk/ocrsdk.com/tree/master/Android

[android-developers] Re: Image dpi, does Android care about it?

[Studio LFP]

Check out this documentation:

http://developer.android.com/guide/practices/screens_support.html#qualifiers

Different image densities can be stored in different folders so Android can 
pick the best one suited for the device. Android also scales images when 
loaded unless they are stored in the drawable-nodpi folder when used in XML.

You can control the scaling of images if you use the BitmapFactory by using 
BitmapFactory.Options and set isScaled to false.

 stretched out and the edge is blurry.

 but when i increase resolution of the same image, say 300 dpi, and display

 so it seems image resolution has an effect here. but i just can't

 http://sourceforge.net/projects/javaocr

  We are focusing primarily on OCR , but OCR also involves some image
  processing - and we could use help
  on this.   There are android demos (not yet complete,  but sampling
  and teaching recognisers work,  corresponding recogniser is not yet
  ready)

[android-developers] Re: Image processing

[Indicator Veritatis]

You should start with the chapter on running Sobel Edge Detection on
Android using the NDK in Android in Action, 2nd or 3rd edition.

The 3rd edition is really written for Honeycomb, so you might want to
go ahead and buy the 2nd which is already available. Or go to the
website for the book and download the code, though it will be hard to
pick up much from it without the accompanying text.

For heavy duty image processing you are likely to want to use the NDK
rather than the SDK. Yet 'zxing' does surprisingly well without using
the NDK. That too is a good project for you to look at, since it uses
image processing for barcode decoding. The Java code is better
documented than many other open source projects.

[android-developers] Re: Image Map Type style Overlay in MapView

[EVK]

Scott. Thanks for sharing this.

I got ImageMapType working on Javascript using getTileUrl method of the 
Google Maps API V3. 
But I am not sure how to do this on Android's native MapView object. I am 
sifting the WWW for a relevant
tutorial which can help me do this, luckily I found your post.

Could you please share some pointers on how to get started on this? How do I 
use overlays on MapView to
achieve ImageMapType kind of functionality? If possible could you share your 
code? or point me to some references 
that you may have used?

Thanks a bunch

If you need just a simple image and some text around you can use

[android-developers] Re: Image Map Type style Overlay in MapView

[Scott Kennedy]

I figured it out.  For anyone else who might be interested, the map
tiles on Android's MapView seem to be twice as dense as the JS API's.
So if you have an existing tileset, just read them in with an
inSampleSize of 2, and adjust the positioning accordingly.

 I have a website where I use the Javascript Maps API, and I use an
 Image Map (http://code.google.com/apis/maps/documentation/javascript/

 in that document.  This works fine for the Javascript API.

 To give a better in-app experience, I'd like to use a MapView, rather
 than a WebView (or opening the browser) with the JS API.  However, I'm
 having a hard time getting the tiles to display properly in the
 MapView.  It doesn't seem to behave the same way as the JS API.  I'm
 not sure whether that's due to tile size, the projection used, or
 something else, but I was wondering if anyone had done something
 similar and could share some ideas or code on how to do this.

Re: [android-developers] Re: Image Picker and Cropper

[Mark Murphy]

Picking an image, yes. Cropping an image, no.

There is some undocumented cropping activity somewhere (Gallery app?),
but it does not work on all devices and, as noted, is not documented.
And even that probably will not let you enforce a specific Width x
Height ratio. Anything that specific would need to be implemented by
you.

[android-developers] Re: Image processing in Android

[Yahel]

Bitmap memory management is buggy and completely unintuitive. It does
not show in MAT as it is allocated in another place and not counted in
the heap. Well it is counted but not easily released or something.

My app is all about images(a world of faces), and here is how I get it
to work most of the time :

//decodes image and scales it to reduce memory consumption
private Bitmap decodeFile(File f){
try {

//decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f),null,o);

//Find the correct scale value. It should be the power of
2.
final int REQUIRED_SIZE=480;
int width_tmp=o.outWidth, height_tmp=o.outHeight;
int sampleSize=1;
while(true){
if(width_tmp/2REQUIRED_SIZE || height_tmp/
2REQUIRED_SIZE)
break;
width_tmp/=2;
height_tmp/=2;
sampleSize*=2;
}


//decode with inSampleSize
Bitmap bitmap = null;
boolean cacheHasBeenCleared = false;

BitmapFactory.Options options = new
BitmapFactory.Options();
options.inSampleSize=sampleSize;
byte[] tempBuffer=new byte[8000];
options.inTempStorage = tempBuffer;

while ( (bitmap == null)  (sampleSize  64) ) {
try {
bitmap = BitmapFactory.decodeStream(new 
FileInputStream(f),
null, options);
} catch (OutOfMemoryError e) {

if (!cacheHasBeenCleared) {
this.clearMemoryCache();

//Try to free up some memory
System.gc();
System.runFinalization();
System.gc();

cacheHasBeenCleared = true;
}

sampleSize *=2;
}
}

return bitmap;

} catch (FileNotFoundException e) {}
return null;
}

The idea is to try to decode the file at top quality. If that throws
out of memory error, it tries to free memory and reopen the file but
with a smaller scale. Rinse and repeat.

Oh and don't think the second system.gc() can be removed that would be
so naïve of you :D That's Android framework we're talking about :D

Good luck with your app.

[android-developers] Re: image upload

[Kumar Bibek]

Well, it's a little different, but it also depends on how the server
is configured to extract and recreate your data. HttpClient is
sufficient for simple file uploads, but getting a multi-part data to
work with your server might be a bit tricky.

Re: [android-developers] Re: image background - how to repeat an image rather than strech it

[Richard Leggett]

An easy way of making a bitmap repeat is to create an XML file in the drawable 
folder which looks something like this:

?xml version=1.0 encoding=utf-8?
bitmap xmlns:android=http://schemas.android.com/apk/res/android;
android:src=@drawable/background 
android:tileMode=repeat /

background is a PNG in the same folder, it doesn't sound like you need a 9 
patch in this case. Simply assign @drawable/repeatingbackground or whatever you 
called the file, in place of the original bitmap. 

As for rounding corners, you can subclass the view you are rendering (let's say 
an ImageView) and use clipping to mask the corners, there are a few examples 
here:

http://stackoverflow.com/questions/2459916/how-to-make-an-imageview-to-have-rounded-corners

I'm presenting techniques here that are more generalised and re-useable and not 
a specific one-off which could be better performance-wise (so if you are making 
a component that's like a progress bar, you'd do this clipping and 
repeat-bitmap drawing in the onDraw() rather than increasing rendertime by 
compositing a separate RoundedImageView and a repeatable BitmapDrawable 
described above).

[android-developers] Re: Image show problem

[Indicator Veritatis]

Well, in a certain important sense, yes, 2.0 is 'obsolete'. But I am
afraid people will read this out of context, so I have to object here:
any Android developer should still keep 2.0 in mind as a probable
target for his applications, even if never the primary target
platform.

That is, most of us should develop using the latest Android 2.3 SDK,
but continue to develop applications that will run well on 2.0, 2.1
and 2.2 devices. Unless you need new bug fixes or new APIs available
only in a later SDK, I would even say it should run on 1.6 devices.

The application I am developing is an example of this: I am using the
2.3 SDK, but the customer will run on a 2.2 phone. So I test on a 2.2
phone. But since the application requires a recent Bluetooth API, I
cannot run it on a 1.6 phone, so there is no point in testing it
there; except to make sure that it doesn't crash (we have done this
test).

I have a give-away app, SylloGizmo, that I originally developed for
Android 1.5. Now since it is hard to even find a 1.5 phone in the wild
anymore, there is not much point in continuing to test it on 1.5. So
whenever I touch the code, I test it on 1.6 and up instead.
This turned out to be valuable, since I found a layout bug that only
appears in 2.1 with a certain choice of screen width and lcd density
(I forget the magic combo now).

It is getting hard to find 2.0 phones too: curious that by any
definition of 'obsolete', 2.0 is more obsolete than 1.6. The Android
Market Dashboard, for example, shows no more than .1% of phones
connecting are using 2.0 -- if even that many.

So summing up: you are right to warn him that no one will consider
sample code or tutorial code to be broken just because it doesn't work
under 2.0. But we should all continue to test against it, except when
our applications require features not available under 2.0. But when we
test, since 2.0 is 'obsolete', we should not be overly concerned about
minor bugs that show up only in 2.0: worry only about crashers.

PS: after seeing the Dashboard, I decided testing against 2.0 is less
important than I thought at first. But the conclusion above stands: we
should still test against it. I will be keeping my 2.0 AVD, I just
won't spend much time on it now that I see how few 2.0 phones there
are out there. But I will still use it for quick testing before new
releases.

Well, it's more like in the official sense.
http://developer.android.com/resources/dashboard/platform-versions.html
* *Other: 0.1% of devices running obsolete versions*

2.0 would fall into the other category.

That is, most of us should develop using the latest Android 2.3 SDK, but

Agreed - mostly. Hell, I still support 1.5 - but that's 6.3% usage,
according to that chart, which is still a pretty good number.
There are enough platform version X screen size configurations to worry
about with wasting time on one that's no longer really a consideration.

If you want to be that thorough, props to you - personally, I think it's a
waste of time. Particularly with the OP simply trying to run a sample app.

What's varying?  The data won't be read back into the same address,
but into a new byte array, and [...@ is just a byte array at a

10) so you can compare their contents.

The addresses vary because they're different objects.  You need to
dump some of the actual byte arrays to see if they're different.  You
could even write code to compare input and output.

Re: [android-developers] Re: Image doesn't appear from sqlite

[Kostya Vasilyev]

+0.02 - this code:

public void insertlistNews(String city,*byte[] newsImageUrl*, String

 publishDate, String expiredDate){

[snip]

  +  VALUES (' + city + ',*' + imageUrl + '*,' + publishDate+
 ',' + expiredDate'););


appends a byte[] to a String.

This is the same as appending String.valueOf(imageUri), which calls 
byte[].toString, which *does not* return the contents of the array, but 
rather its type marker and address - which does look like [...@437c1338 
and so on.


If you want to insert byte[] values into the database, use one of:

- SQLiteStatement and bindBlob(int index, byte[] value)

- DatabaseUtils.InsertHelper and bind(int index, byte[] value)

- ContentValues, put(String key, byte[] value), and SQLiteDatabase.insert()

If you mean to insert the URL as a string, make sure you use a String 
variable for the URL to build your SQL statement.


Perhaps you are trying to do both (your code sample uses two different 
variable names: newsImageUrl and imageUrl), so do each one as described 
above.

[android-developers] Re: image resolutions and scaling

[Vinay]

Hai All,

Adding on to this thread, since I facing an issue very much related to
this.

I did go through the Multiple screen support document:
http://developer.android.com/guide/practices/screens_support.html

I'm using freescale imx51 board connected to a DELL 14 TFT monitor.
The default applications do appear full screen. But when I port my
custom application it renders in compatibility mode.

I have all the three folders (hdpi, ldpi, mdpi) holding density
specific images.

First I tested my application on the emulator (Medium Density / Normal
Screen). Hence my image size were specific to 480X320 (Landscape
mode). I generated hdpi and ldpi images as stated in earlier post:
hdpi = 1.5 x mdpi
ldpi = 0.75 x mdpi

Why is the custom application not being rendered full screen like all
other default application. Why are images not being scaled to fit the
DELL 14 monitor connected to the imx51 board.

Thanks for any help.

Vinay.

  Hello,
  In order to ensure that my app looks good on devices with different
  screens I have to store my images (icons, etc,..) in the three folders
  for ldpi, mdpi and hdpi so that android can scale the images, right?
  Now how do i know which resolution the single pictures must have? For
  example I have two images for a navigation bar. Now I store these
  images for instance with size 60x60 in the hdpi folder which sizes
  do i have to choose for the mdpi and the ldpi folder? how do I know
  this?

[android-developers] Re: Image loading from remote problem

[umakantpatil]

Kumar,
I have already checked your pages. Its shows example for drawable
which you have on mobile.
I want to load remote image. As remote image loading takes long time.
UI hangs up till the time.

I have also seen that you have written saying that we can pass null
and open new thread which downloads image to local.
Replace's the path to local file in html and then reset the text in
TextView.

This works fine when textview has one image but when our text has 2/3
img tags. Each time getter is called and 2/3 new threads get open and
2/3 times text is reset.
Lets imagine case where means while image downloads in new thread then
user goes to other activity and the one which we opened is destroyed.
Also the case where in same acitivty i have 2/3 pages like which has
next and prev button. So the image comes bit late and then the thread
will take other text and replace it somewhere else

I dont know but Im going it in big confusion. Is there some direct
widget for this ?

I dont want to use webview as I have some other things which gets
disturb because of webview. Need to it in textview only.
