[android-developers] Re: Abort SMS broadcast

[squeakypants]

I'm working on a Twitter app that works though SMS. Twitter has a
normal API, but I don't plan on getting an internet plan (and I doubt
I'm the only one), and I'd still like to receive them on my phone.
However, having to look at Tweets as normal text messages wouldn't be
as comfortable as in a dedicated app.

I'm having the same problem as the person who started this thread:
While my app receives the tweets fine, it doesn't "intercept" them
from the Messaging app. I understand why you don't want apps to have
this ability, but isn't that why you list an app's permissions before
installation (as shown in the marketplace screens)? I do plan on
notifying the user just like the Messaging app, and receiving it in
two apps would be more annoying than helpful.

Do you have any suggestions on what I can do? It's noteworthy that it
will only "intercept" Twitter messages (from number 40404), and anyone
who uses Twitter via SMS (on any phone) knows how many texts they get
from it.

Thanks,
squeakypants

[android-developers] Re: Search Invoke sample

[Andrew Stadler]

That's a bug in the Sample.

On the emulator, you can use F5 to bring up Search (in the sample's
"automatic" mode).  For comparison, if you select "Disabled", F5 no
longer works - simulating an activity where you do not want to support
any search capabilities.

For comparison, you can see this in the browser, too - you can can use
menu-search or you can use F5, and both will bring up a search box.

If you'd like to file a bug, you can help make sure that the sample gets fixed.

(Note, "emulator -help-keys" provides a complete list of special keys
in the emulator)

Thanks,
Andy

[android-developers] Search Invoke sample

Question on the API demo - Search Invoke

I launched this sample and have selected "Automatic" in the spinner. I
also see a menu option "Automatic". When this menu option is selected,
it pops an alert that says "To invoke search try menu+S"

However, menu+S doesn't bring the search dialog.  Any issues?

[android-developers] Re: Orientation changes simulation

[hackbod]

It sounds like you will generally be in good shape, but again I will
say -- you should always always run your app on at least one piece of
real hardware before releasing it.  This app will be running in a
completely different environment (interpreted dalvik code), and the
general user experience on real hardware just can not be emulated.
Things like the screen density, interaction with the touch screen,
etc.  Personally I don't think running a previous J2ME version on some
other hardware counts as running the current Android version on the
corresponding hardware.

Btw, looking back, you are talking about making a talking compass that

[android-developers] Re: Orientation changes simulation

[blindfold]

Good points, hackbod. My app is mostly a port from an existing J2ME
app that runs on many physical Nokia phones, so I guess I have a fair
idea of the performance that I may expect because my CPU intensive
parts are actually identical on J2ME and Android. If I may believe the
rumors that the first Android phone will have a 500+ MHz processor, I
would be surprised if Android did worse than what I get with J2ME,
although there are still some Android-specific performance concerns.
One is stemming from the inability to play byte arrays in Android
(J2ME can do that), for which the current workaround is to write these
arrays to file (slow flash on physical phones?) and play these file
chunks with MediaPlayer. Another Android performance concern is that
one can currently not use the byte arrays coming from PreviewCallback
because of image format incompatibilities, while using PictureCallback
is probably less efficient for small images. Both concerns I feel are
more related to Android versus J2ME than to the physical phones, and
may be addressed through issues 398 and 739. Of course you are right
that I can only tell how badly these two factors limit performance
after trying a physical Android phone - or waiting for feedback from
Android phone users.

Thanks

Hello Felix,

You can easily change the default skin of the emulator to a skin which
does not have a keyboard at all.

This link will help you for this;

Business search is not a part of the current API, so you can only search
places or addresses..
For details see the API docs below:

[android-developers] How to use the mic for audio-input in android

[HTP]

Hi!

I'm trying to make an app that records audio from the microphone. In
the new the SDK i think the emulator supports audio capturing. But I
don't understand how to get the emulator to use my computers
microphone.

The emulator pages says that I have to start the emulator this way:
emulator -audio-in 
But I can't find any information about how to define  so it
will use my computer's mic.
Or use a -wav file as audio input.
Does anybody know?
Thanks in advance!

If you connect mic to your PC, the emulator should be able to detect it
without any additional launch flags.

I'm a bit confused. When I open the Contacts activity, and choose New 
Contact from the options menu, I get an activity that probably isn't a 
ListView. That's probably just a LinearLayout popped in a ScrollView to 
handle the extra length.

Are you referring to something else?

What happens on a rotation is that your activity is shut down and 
restarted with the new resource set.

During the shutdown process, onSaveInstanceState() will be called, and 
you'll get that Bundle back on the ensuing onCreate().

Since I'm not seeing the same activity as the one you're describing, I 
can't say for certain, but it might be a footer view. Try 
ListView#addFooterView().

[android-developers] Re: ListView and custom rows containing EditText

[Jeff Hamilton]

ListView isn't really meant to handle that type of UI with editable
entries, as it manages the selection state of the items directly. It's
designed to handle long lists of items that don't take focus
themselves.

The contact editing screen is using a vertical LinearLayout wrapped in
a ScrollView, containing horizontal LinearLayours of the EditTexts and
Buttons. When using a ScrollView you can set
android:fillViewport="true" in your layout file to get it to fill up
the entire screen, which is how contacts pushes the buttons to the
bottom.

How to get web search results in an application (without launching the

Since MapView's setOnLongPressListener() method is now removed...if you need

handling the OnTouchEvent() and passing it on to a GestureDetector to handle
it yourself..

[android-developers] ListView and custom rows containing EditText

[istv]

Hello everyone,
 I had problems today concerning ListView/ListAdapter... I'd like to
get an activity that is very similar to the "New contact" one in v0.9.
Basically a ListView, that is expandable by custom rows containing
EditText, RateBars, etc..
I tried by extending BaseAdapter's onView (the simple way by inflating
layout-xmls per row), which actually worked, but nevertheless, it
raised a couple of problems which I want to address here.

1. Whenever I "touch" an EditText and start typing, the focus jumps to
the respective EditText of the first row that has the same inflated
listitem-layout. Navigating with keys works.

2. Changing orientation of the device in emulator (Ctrl+F12) causes
the EditTexts to lose all changes made. Do I really need to save their
states manually?

3. How to get a row that sticks to the bottom (the two buttons in "New
contact")? It is apparently achieved by an additional row containing
nothing.


So, are there any solutions around that I did not see yet? I had a
look at Mark Murphy's blog, and also some of the tutorials on
anddev.org..

Thanks & Cheers,
 István

[android-developers] Re: allocation in loop each 1s

[barbapapaz]

For framerate I'm talking about number of request by time unit. Each
request I get messages and display it on map. I launch request only if
map move

Thanks for your advices!

Nobody should publish their app without first running it on actual
hardware.  Once phones become available, anyone who is developing
should have a phone to test and run their app on.  You can't expect
the emulator to provide 100% fidelity with real hardware, and it
certainly won't give enough fidelity to be able to judge the real
experience on hardware.  If you only ever run in the emulator, you
will ultimately end up with a poor application.

Hello it's for a map application you can see a video here
http://www.youtube.com/watch?v=3cHyRdLi1D8

What are rational framerate for this type of application? For example
when you use google map or google earth what is methodology?

Thanks for your interest

[android-developers] Re: allocation in loop each 1s

[hackbod]

I'm not sure what you mean by framerate...  we are talking about http
requests, right?  They shouldn't be tied to a frame rate.  You really
need to think about the repercussions of running on a mobile device:

- When on a EDGE network, it can easily take more than a second just
to set up a network connection.
- Opening a network connection puts the device in to a high power
state, and it will remain in that state for at least 10 seconds as it
expects more network traffic.  This will drain the battery very
quickly.
- Even if you get the network connection up in time, it is doubtful
you will get all of your data back within 1 second.

As a target, I would recommend trying to do a network connection no
more than once a minute (and this only when your app is in the
foreground; when in the background you want to be much more frugal
than that).  In that connection, you can retrieve all of the
information around the current area that you might be interested in.
That is, batch your requests so that you can get a lot of data in a
small number of batches, to help mitigate the impact of network
connection delays and bringing the device in to a high power state by
performing network activity.

Another option you can use is to keep a persistent connection open
while your app is in the foreground, which the server and client talk
back and forth on as needed.  When there is no traffic on the
connection the device can go into a lower power state (though there is
still the delay so you still want to batch interactions as much as
possible), but this avoids the initial setup overhead.  I'm not sure
how useful this is for doing repeated requests, except for getting rid
of the htttp and network setup overhead, but it can be very useful
when a server is pushing data to an app on the server's schedule.

[android-developers] Re: allocation in loop each 1s

[hackbod]

You are making an http request every second?  Though I don't know what
you are doing, that seems way too frequent to me.  This will be very
hard on the battery, effectively causing the device to keep its radio
turned on in a high power state for the entire time you are running.

[android-developers] Re: Multipart Messages - Is there an example how to get them work now. (Uploading to a web API)

[Rajesh]

Hi James,
I downloaded the apache common jars and added them to my build path,
but still I get "org.apache.http.entity.mime" cant be resolved.
Don't know if I'm doing something wrong. I just followed the steps you
had explained. Kindly let me know if there is anything extra I should
do with eclipse.

Thanks and regards,
Rajesh

[android-developers] Re: Orientation changes simulation

[hackbod]

Testing across multiple devices may be needed, though our goal is
certainly to have much more consistency across devices than J2ME does.

Testing on at least -one- device, however, should be a basic
expectation.  If you are running on the emulator, you have no idea how
your app will behave on actual hardware.

I don't think we are expecting developers to have their apps up on the
marketplace the first day devices are shipped.  At least, if I was a
developer, I certainly wouldn't want to do that, because I would have
no idea how my app would actually behave on real hardware.  Since
Android is about a third party developer ecosystem as much as it is
about a phone platform, we are in the somewhat tricky situation where
initial hardware is available at the same time for both users and
developers, which does imply that developers won't have their
applications available to users the first day devices are on sale.

[android-developers] Re: Setting highlight text color (textColorHighlight doesn't do it)

[Megha Joshi]

If you want the textcolor to change to white when you select it...you should
use ColorStateList.

Say, you have a ColorStateList drawable  named textcolor:

http://schemas.android.com/apk/res/android";>




you can set your textview's attributes to:

android:textColorHighlight="#00f"
android:textColor="@drawable/textcolor"

I don't know what your assumptions on resource constraints are, but
while developing for J2ME, I've had to deal with a wide variety of
firmware issues making that no single phone is representative either
any more than an emulator, and the cost of testing on the myriad of
Symbian based phones is for most developers prohibitive. I do not
see how Android will be much different in this respect.

The emulator had better be fairly representative, although of course
I'd love to play with the first physical Android phone if I can find
one. :-)

[android-developers] Does getLocationFromName work in 0.9?

[[EMAIL PROTECTED]]

Does anyone know if getLocationFromName (with a bounding box) works in
0.9? I can use the simpler version just fine:

public List getFromLocationName(String locationName, int
maxResults)

When I use the version that accepts a bounding box, I always get a
null result:
public List getFromLocationName(String locationName, int
maxResults, double lowerLeftLatitude, double lowerLeftLongitude,
double upperRightLatitude, double upperRightLongitude)

Has anyone successfully used it?

I somehow improved Justins code.

See http://pastebin.com/m1f06415f 

It has now a New-York based journey (longer than before) and the
time-interval between each points can be set so that the update inveral
(set to 500ms) can be arbitraryly small (see line 177)

[android-developers] Re: Will android provide Mail API??

[hackbod]

Where did you get these classes from?  These are not part of the SDK,
nor internal implementation of the platform, as far as I know.  Given
that, you shouldn't be having classes in the com.android namespace,
since that is reserved for android.

[android-developers] Httpunit and Android

[acet]

Hello all,
has anyone had any experience with using httpunit in an android
project? I have been unable to build my eclipse project once i have
imported the required files for httpunit.

When I import the httpuint jar files:

activation-1.1.jar
js-1.6R5.jar
jtidy-4aug2000r7-dev.jar
junit-3.8.1.jar
mail-1.4.jar
nekohtml-0.9.5.jar
servlet-api-2.4.jar
xercesImpl-2.6.1.jar
xmlParserAPIs-2.6.1.jar
httpunit.jar

After adding all the jar files to the build path of the project I
receive this error when trying to build:

[android-developers] Re: Some help with webservices?!

[kennyg]

Did you set the android.permission.INTERNET permission in the
Android.Manifest.xml?

Not providing this leads to unexpected errors when connecting.

[android-developers] Re: Bug in Bitmap.compress when used on JPEGs?

[kp]

Maybe some of the requests are getting blocked. Try adding connect and
read timeouts by replacing url.openStream() with
openConnection().getInputStream():

...
URL url = uri.toURL();
URLConnection con = url.openConnection();
con.setConnectTimeout(3000);
con.setReadTimeout(3000);
Bitmap bmp = BitmapFactory.decodeStream(con.getInputStream());
...

Adjust the 3000 ms timeout values if necessary.

You can add exception handling for the connection timeouts.

Regards,

Kim

You want an options menu, typically defined in 
Activity#onCreateOptionsMenu() on onPrepareOptionsMenu().

To create your submenu, use Menu#addSubMenu().

If you have specific questions or problems with implementing option 
menus, write back!

[android-developers] Some help with webservices?!

[Cezar Augustus Signori]

Hi all!

i still try to send/receive data from/to webservices...well, i tried
the kSoap2 (as almost of us), but all that i get is an "unknown error"
message.

After some tries, i've decided to simple send XML to the webservice
through a connection and receive the response as String to later
handle it with some XML parser. But all i can get is a bug "Does Not
Support Output" message from the URLConnection. If i use another class
such HttpUrlConnection from java.net or apache,  the "unknown error"
message comes again.

I tried things like described:

http://www.anddev.org/calling_a_web_service_from_android-t348.html
http://chitgoks.blogspot.com/2008/03/android-and-web-services.html
and other resources from this group..

Thanks in advance!

[android-developers] Re: Bug in Bitmap.compress when used on JPEGs?

[snowcrash]

Hi there,

I think I was able to track it down.
It seems to be based on how the JPEG was saved. If it was saved using
Photoshop in 'normal' mode, it doesn't work. If it's saved using 'Save
for Web & Devices...', it works. The same applies for saving it with
GIMP, it then works flawlessly, too.
I did a 'strings ' in a terminal on the different files, and
it yielded that saving it in Photoshop/normal mode puts quite a bunch
of extra material like EXIF and additional Photoshop-metadata in the
file. This seems to make something inside Android (OpenCORE?) choke on
it.

Can anyone confirm this?

Cheers,
snowcrash

@Kim: It wasn't a timeout, but it is a good idea to set one
nevertheless. Thank you!

try changing

private GeoPoint mRandomPoint = new GeoPoint(5309691, 8851933);
to some thing like this
currentPoint = new GeoPoint((int) (-43.2973 * 100), (int) (172.5929 
* 100));
the map is draw much faster

[android-developers] Background image disapearing

[etooler]

Hi All,

I have been tinkering with the Notepad V1 tutorial to try out a few
things. One thing that I did was put a background image in the linear
layout using the android:background attribute in the
notepage_list.xml
layout file. This works as expected.
When I run the application, if I click the mouse and drag it, two
things that I cannot explain happen:

1.) The background image disappears as soon as I start to drag the
mouse with the left mouse button held down (I assume this is
simulating a finger drag on a touch screen). The image comes back
when
I unclick the left mouse button.
2.) When I drag the mouse up, the list of notes scrolls down and when
I drag the mouse up, the list of notes scrolls down (this seems
counter intuitive to me).

Is there anyway to ensure that the background image is always
rendered
when scrolling? The other thing that I can't determine is what the
orange color indicates? Does this mean that the element in the UI is
selected? Is there anyway to change this colour?

 Thanks for any information people can provide.

[android-developers] allocation in loop each 1s

[barbapapaz]

Hello

I have question about efficiency in loop. In my app I have loop called
with sceduler each second. In this loop I launch request with
httpclient, I must cronstruct an entity with MultipartEntity.

this procedure explain here (http://groups.google.com/group/android-
developers/browse_thread/thread/e4230ed22c196772/1284daa5723acd0c?
lnk=gst&q=MultipartEntity#1284daa5723acd0c)


ContentBody[] parts =   {new
StringBody(Float.toString(latitudeMin)),
  new 
StringBody(Float.toString(latitudeMax)),
  new 
StringBody(Float.toString(longitudeMin)),
  new 
StringBody(Float.toString(longitudeMax)),
  new 
StringBody(dateMin),
  new 
StringBody(dateMax),
  new 
StringBody(noteMin),
  new 
StringBody(categories)
};

MultipartEntity getMessagesRequestContent = new 
MultipartEntity();
getMessagesRequestContent.addPart("latitudeMin", 
parts[0]);
getMessagesRequestContent.addPart("latitudeMax", 
parts[1]);
getMessagesRequestContent.addPart("longitudeMin", 
parts[2]);
getMessagesRequestContent.addPart("longitudeMax", 
parts[3]);
getMessagesRequestContent.addPart("dateMin", parts[4]);
getMessagesRequestContent.addPart("dateMax", parts[5]);
getMessagesRequestContent.addPart("noteMin", parts[6]);
getMessagesRequestContent.addPart("categories", 
parts[7]);

In this code there are lot of "new" and the garbage collector is often
called!
MultipartEntity and StringBody objects aren't clear or erase function,
I must called new each loop!

Do you think that is no problem?
Do you think that I musn't use this new (do you have solution)?

MultipartEntity and StringBody objects are in an opensource library
(code here http://hc.apache.org/httpcomponents-client/httpmime/xref/index.html).
Do you think that I must write clear funtion to don't called new
function (and recompile)?

Thanks

[android-developers] How to transfer Image bytes from MediaStore.Image ContentProvider to byte [] array

[Graeme]

Hi

I am puzzled how best to copy a JPEG image data bytes held by the
MediaStore.Images ContentProvider to a byte []  within an Activity. I
am not certain about how the java.io
Classses fit into my scenario...

So a sketch of the code might look something like ...

import android.provider.MediaStore.Images;
import android.net.Uri;
import android.database.Cursor;




Uri extImagesUri = Images.Media.EXTERNAL_CONTENT_URI; // Images on SD
Card
// Obtain a  Cursor
Cursor cur = managedQuery(extImagesUri, null, null, null, null);
int rowIndex = cur.getColumnIndexOrThrow(Images.ImageColumns._ID);
Uri imageUri = null;
byte [] imageBytes = null;
String rowStr = null;
InputStream inStream=null;
OutputStream outStream = null;


// Iterate through cursor rows
cur.moveToFirst();
while ( cur.moveToNext()  )  {

// Get RowID
long rowID = cur.getLong( rowIndex );

// Image URI
rowStr = (new Long(rowID)).toString();
imageUri = Uri.withAppendedPath(extImagesUri, rowStr) ;

   // Now open an InputStream or OutputStream or a File ??
   
   inStream = getContentResolver().openInputStream( imageUri );
  // OR ??
   outStream = getContentResolver().openOutputStream( imageUri );
  // OR ??
ParcelFiledescriptor pFD = getContentResolver().
openFileDescriptor(imageUri, "r");
// then open a FileInputStream ??



   // transfer (copy) image content bytes  to imageBytes array
   < Please help here !!>

   // do something with imageBytes ...

}

Can someone please give me some pointers. I am rather a Java newbie
so
am notclear about which of the java.io classes to leverage.

Thanks
Graeme

[android-developers] Re: getScale replacement for BaseAdapter in 0.9 beta?

[Chris Cicc]

Hey,
I appreciate the prompt reply. Unfortunately I'm having trouble making
complete sense of your instructions. I admit I'm new to Java and
Android (though I'm very experienced in C#.NET so I'm picking it up
pretty quickly).

Right now I have the following code in an activity:

Gallery gal = new Gallery(ctx);
gal.setLayoutParams(new 
LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
gal.setAdapter(new HomeGalImgAdapter(ctx));
gal.setHorizontalFadingEdgeEnabled(true);
gal.setSpacing(0);
gal.setClickable(true);
gal.setFocusable(true);
//  gal.setUnselectedAlpha(0.5f);
topPanel.addView(gal);

Along with this image adapter class:

public class HomeGalImgAdapter extends BaseAdapter {
private Context myContext;

private int[] myImageIds = {
R.drawable.test128_add_to_folder,
R.drawable.test128_calendar,
R.drawable.test128_chart_pie,
R.drawable.test128_clock,
R.drawable.test128_comments
};
public HomeGalImgAdapter(Context c) { this.myContext = c; }
public int getCount() { return this.myImageIds.length; }
public Object getItem(int position) { return position; }
public long getItemId(int position) { return position; }

public View getView(int position, View convertView, ViewGroup parent)
{
ImageView i = new ImageView(this.myContext);

i.setImageResource(this.myImageIds[position]);
/* Image should be scaled as width/height are set. */
i.setScaleType(ImageView.ScaleType.FIT_XY);
/* Set the Width/Height of the ImageView. */
i.setLayoutParams(new Gallery.LayoutParams(96, 96));
return i;
}
}

This works perfectly, and the gallery displays with a bunch of other
content. How do I implement your suggestion to have the not-in-focus
images be scaled smaller?

Also, I am trying to figure out how to set a TextView to act as a
caption whenever the picture changes focus, but at the moment as soon
as I start scrolling through the gallery and the first image loses
focus I am unable to get another image to take focus. Still trying to
figure that one out...

Thanks for your help!

I appreciate the prompt reply. Unfortunately I'm having trouble making
complete sense of your instructions. I admit I'm new to Java and
Android (though I'm very experienced in C#.NET so I'm picking it up
pretty quickly).

Right now I have the following code in an activity:

Gallery gal = new Gallery(ctx);
gal.setLayoutParams(new 
LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
gal.setAdapter(new HomeGalImgAdapter(ctx));
gal.setHorizontalFadingEdgeEnabled(true);
gal.setSpacing(0);
gal.setClickable(true);
gal.setFocusable(true);
//  gal.setUnselectedAlpha(0.5f);
topPanel.addView(gal);

[android-developers] Re: Bug in Bitmap.compress when used on JPEGs?

[Kim Pedersen]

Maybe some of the requests are getting blocked. Try adding connect and
read timeouts by rewriting the url.openStream() to
openConnection().getInputStream():

...
URL url = uri.toURL();
URLConnection con = url.openConnection();
con.setConnectTimeout(3000);
con.setReadTimeout(3000);
Bitmap bmp = BitmapFactory.decodeStream(con.getInputStream());
...

Adjust the 3000 ms timeout values if necessary.

You can add exception handling for the connection timeouts.

Kim

[android-developers] Re: Orientation changes simulation

[Andrew Stadler]

Just to clarify things a bit, two different forms of orientation are
being discussed here.

The orientation changes that are triggered by emulator keys are
"gross" orientation of the device itself - primarily, is the screen in
portrait or landscape mode.  Because the screen will be laid out
differently for portrait vs. landscape orientations, this has direct
impact on the view system and your activities.  See

for more information.

Finer-grained orientation changes, such as those that might come from
sensors such as an accelerometer, and do not immediately impact the
view system, are provided via the android.hardware.SensorManager and
android.hardware.SensorListener classes.

It is helpful to clarify which type you're interested in, as the
answers are quite different.

[android-developers] MediaPlayer and LocalSocket problem

[3,14]

I want to set LocalSocket FileDescriptor as a data source for the
MediaPlayer. Here is my code:

public class sipActivity extends Activity {
public static final String S_ADDR = "test.server";

public class Server implements Runnable {
public LocalSocket receiver = null;

public void run() {
try {
LocalServerSocket server = new LocalServerSocket 
(S_ADDR);
while (receiver == null) {
receiver = server.accept();
}
} catch (Exception e) {
Log.e("me", "ooops", e);
}
}
}

public class MediaWriter implements Runnable {
public LocalSocket sender = null;

public void run() {
try {
sender = new LocalSocket();
sender.connect(new LocalSocketAddress(S_ADDR));
FileInputStream media = new 
FileInputStream("/system/media/
audio/alarms/Alarm_Classic.ogg");
int readed;
byte [] b = new byte [1024];
do {
readed = media.read(b);
if (readed > 0) {
sender.getOutputStream().write(b, 0, 
readed);
}
} while (readed > -1);
} catch (Exception e) {
Log.e("me", "ooops", e);
}
}
}

/** Called when the activity is first created. */
@Override

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

try {
Server mServer = new Server ();
new Thread (mServer).start();
MediaWriter mMedia = new MediaWriter ();
new Thread (mMedia).start();
while (mServer.receiver == null) {
Thread.sleep(10);
}
MediaPlayer mMediaPlayer = new MediaPlayer();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 
mMediaPlayer.setDataSource(mServer.receiver.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();
} catch(Exception e) {
Log.e("me", "ooops", e);
}
}
}

But I got an exception on the line:
mMediaPlayer.setDataSource(mServer.receiver.getFileDescriptor());

The error is following:
java.io.IOException: setDataSourceFD failed: status=0x8000
  at android.Media.MediaPlayer.setDataSource(Native Method)
  at android.Media.MediaPlayer.setDataSource(MediaPlayer.java:251)
  ...
