Re: [android-developers] Compiling Android Source

[Andrew]

Well that does make more sense. I guess the point at which lunch stopped 
working was when I restarted the shell. So I then when and installed lunch, 
which then overrode and use of the lunch script from then on.

Any thoughts on the linking error when compiling using -j4? (That being 
said, having completely removed and re-downloaded the source - there have 
been no errors with char casting I didn't realise that was a missing 32-bit 
library... and I am running make using -j4 and it has already gone way past 
where it normally stops...).

I am not really trying to develop for a particular device at this point - I 
am just trying to write an app that uses some of those 'private' libraries. 
However when Honeycomb source comes out I will be after that. Busy breaking 
in my XOOM right now...

Thanks for the help

[android-developers] View & Open files downloaded from the server

[Salma hamed]

Hi,
I'm having an Android Ftp Client, I download different types of files
(.txt , .pdf , .mp3) from the server. And then I list all the files I
downloaded.
So my questions are as follows:
1) if I downloaded it on the internal memory of the Android device. Is
there a way to view the file ??
2) If the file is on the SD card & I listed the files by their names.
What I want to do is that by clicking on the name the file is opened.
Meaning if the file name is "test.pdf" & I clicked on it it should be
opened in the same way the pdf file is opened in the pdf viewer, Same
thing goes for mp3 files for example, by clicking on the file I want
it to be played.

Thanks alot for the help in advance

Wait you reinstalled lunch? `lunch' is a bash function that is
accessible after sourcing build/envsetup.sh. It is not a program that is
actually 'installed'. The lunch function finds all the device/vendor
configs in the source tree and then allows you to choose one to set as
your product. Once this is done, you can build Android specifically for
that product.

Man you gotta set up the android build environment with `.
build/envsetup.sh'. And then you can run lunch, as well as a bunch of
other helpful tools.

You'll probably need to install some more 32bit libraries before it will
build.  And also, if you are building for any actual device you will
need to obtain that devices' proprietary files from its configuration
directory (if it has one).

[android-developers] Compiling Android Source

[Andrew]

I am having some difficulty compiling the source code. This post is
largely posting my problems and solutions that I was unable to find
anywhere else.

(I have been following the directions from here:
http://source.android.com/source/downloading.html)

Repo seems to be downloading the code without a problem.

When I run make...

initially I encountered compiler errors having to do with const char* -
> char* for several instances of strchar(...) and strrchar(...) being
invalid. I corrected these errors by casting using
strchar((char*)...).

I encountered and error having to do with something not being able to
find '-lasound'. I reinstalled lib-asound a few times, the correct
solution was to install the 32-bit library for it.

Then I encountered and error with a something not being able to find
the wx/wxprec.h header file. (wx was not on that list of stuff to
install, however I needed to install libwxbase2.8-dev and then move
the it from /usr/include/wx-2.8/wx/* to /usr/include/wx/*

I have attempted to run make using 'make -j4' (my computer has a dual
core processor), however it gets a few minutes into the compile and
gives a linking error with a .so file. if I just run 'make' with no
arguments it passes that point by over an hour, but obviously takes a
longer time to get there. I was also looking into using distcc to
spread out the load across another computer or two - but I am not sure
if there is anything to be gained (it looks like a large portion of
the work is linking and not actual compiling).

Addititonally, while I was able to run 'lunch' the first few times, it
seems to have broken since, and now when I run lunch it says:

Using lunch master without the GUI.
No such file: /home/andrew/.lunchrc.

I have redownloaded the repo and reinstalled lunch with no effect.

[android-developers] Re: EditText to filter a listview

[mathe...@gmail.com]

I think the problem is that your RestaurantInfo needs to implement
toString() so that it can be filtered on correctly.

If you use the other flavor of scanFile, one that takes a
MediaScannerConnection.OnScanCompletedListener object, you will need
to implement onScanCompleted() in that listener.

You would use the Uri if you wanted to query the MediaStore to get
more information about the file that was scanned. Or, if it is null,
the file was not scanned for some reason (corrupt?).

There is no Uri. The parameters to scanFile() are a path and a MIME type.

I'm glad to hear you've got a solution!

However, opening the file should never cause the IDE to freeze, so I'd
like to find out exactly what you did to see if I can reproduce it
here -- and more importantly, fix it. I've tried using the "New XML
File" (the builtin Eclipse template instead of the Android specific
one) and that too worked for me. So can you tell me in very explicit
detail what you did? E.g. you created a folder called "Menu" under
"Res", presumably using the new-wizard, and then how did you place a
new XML file in there? Using a wizard (if so, which template?), or
copying from elsewhere, or did you do it on disk using file explorer
or something? If so, what were the exact contents of the file you
placed there?

Thanks,
  Tor

Many thanks,
I'm using now Asyntask and I'm using Toast in PreExecute and
PostExecute methods.

Re: [android-developers] Re: help: dont display Toast

[Kostya Vasilyev]

Your code, as far as I can tell, runs inside onCreate. Android UI framework
is designed so that it expects callbacks like onCreate and others to return
control to Android within a reasonable amount of time.

Your code prevents Android from doing things in the UI, including showing
toasts (or dialogs), because it ties up the UI thread with your work
function.

Study Application fundamentals in the SDK documentation, specifically
information about threads, it does a good job at explaining this.

To run networking code, create a background thread. An easy way to do it is
to use AsyncTask, a generic class provided by the Android framework.

Re: [android-developers] Re: refresh the gallery without restart the emulator

[Mark Murphy]

You use the MediaScannerConnection when you add a new file to external
storage that the MediaStore needs. Your code below seems to have
nothing to do with adding new files to external storage.

You have your Toast message inside an if, are you sure that condition is
satisfied? Also, if you uncomment the first toast, does it show?

[android-developers] Re: refresh the gallery without restart the emulator

[cervello]

Should I do something like this? but it's not correct..

public void onCreate( Bundle savedInstanceState ) {

super.onCreate( savedInstanceState );
setContentView( R.layout.main );

ListView videoListView = (ListView)findViewById(R.id.List);
videoListView.setAdapter(new ArrayAdapter(this,
android.R.layout.simple_list_item_1, getListOfVideos()));

 
videoListView.setOnItemClickListener(videoListItemClickListener);

MediaScannerConnection mScanner;

mScanner = new MediaScannerConnection(this, new
MediaScannerConnection.MediaScannerConnectionClient() {
public void onMediaScannerConnected() {
mScanner.scanFile(filename2, null /* mimeType 
*/);
}

public void onScanCompleted(String path, Uri uri) {
if (path.equals(filename2.toString())) {
mScanner.disconnect();
 }
 }
});

mScanner.connect();
 }

I've installed the app in the devices but the Toast doesnt shows.
The complete Oncreate is:

 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d("PRUEBA", "COMENZAMOS EL PROGRAMA");

   // Toast.makeText(ssh.this, "",

InetAddress pp;

Log.d("PRUEBA","No llega despues de comprobar el primer ping.
Hay que mandar paquete");
Toast.makeText(this, "",
Toast.LENGTH_SHORT).show();

wakeonLan();
Toast.makeText(this, "",

mandarSsh();
}else{

[android-developers] Message Dialog appears, The market billing service is not available, Dungeons Sample, Although i have followed the steps given in documents.

[muhammad mahmood]

Hi,

As Android Market In-app Billing  is now available to developers and
users to publish applications that use Android Market's in-app billing
service.

To implement this, i followed the instruction provided in
"Implementing In-app Billing" document carefully.

1. Downloading the Sample Application
2. Configuring and building the sample application
3.Uploading the sample application
4.Running the sample application

After completing these steps when i run the sample app, dialog appears
with following title and message.

Can't make purchases
The market billing service is not available at this time. You can
continue to use this app but you would not be able to make purchase.

How to resolve this issue.?

Kind regards,
Muhammad Rashid

[android-developers] Image manipulation at high level

[luiX_]

Hi,

I'm looking for any lib that allows me to apply some effects to images from
my android app. There are different effects I would like to apply, from
color filtering (ok, that's easy) to a "polarized" effect (adding the frame
around the image). I'll love to be able to use ImageMagick in Android but I
think that's not possible.

Do you guys know any lib I could use to do a high level manipulation in
Android? or any way to use ImageMagick in Android?

Thanks!

The toast will only show after your code returns from onCreate, which it
should.

Hmm... that should work fine.

Are you running that in a real device? I've had problems not seeing Toasts

Ping and Java have never worked terribly well together, due to
historically weak ICMP packet support. I would try to find some other
solution to whatever problem you are trying to solve.

It's not that hard, if your preferences will work OK all concatenated
together. Here's a sample project that uses PreferenceFragment on 3.0
and "classic" preferences pre-3.0:

Get Android source and build against the same libs/headers.
Interfaces might differ between Android versions, so you'd
better stick with EVP/standard stuff.

Besides, you are going to monitor cellphone battery state, not control

[android-developers] Re: Background service stay alive

[Eason]

Thanks for ur reply =]
But what i wonder is, if i only update the battery state every 5 mins,
the update would be a bit too late.

I can see on the market there is some battery widget doing the same
(i.e. give immediate response when the phone is plugged to the AC),
how can i do the same??

for the music player, the problem is, if accidentally the service is
killed, my app will be totally crapped. I use singleton on my service
and start it when my app is started, and control the media player
through the service. So if the service is died at some point, if i
want to get the playback time or do anything with the service, my app
will not be working anymore. Are there any better implementation can
be done on my app? I feel so frustrated about it...

[android-developers] Access to phone's built-in OpenSSL?

[DanH]

As I understand it, OpenSSL is a part of the standard build for
Android phones.  Is there any way for an NDK app to access the OpenSSL
encryption interfaces?

I understand that one could simply compile a separate copy of OpenSSL
with the app, but, in addition to being stupid from a storage point of
view, this isn't legally possible, since the app could then not be
shipped out of the US without being "blessed" (which takes months).

So, is there some way to access the built-in facilities?  (This isn't
for data transmission, so simply using HTTPS isn't a solution.)

Hi,

I am facing problem with list selector.

The code is as follows:

*2) list_selector.xml*


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






Still it is not taking any effect on the list item getting displayed.  The
default color is coming on selection instead of customised one.
I will be grateful if any help is provided on this

[android-developers] Canvas problem using drawing square around face

[Ian Menzies]

Hey guys,

I have a program that successfully accesses a gallery, allows a user
to select a picture from that gallery, and display that pic to the
user. I have tried to add a facedetector into this program but some
issues have arised, the picture is still displayed to the user but
when I try to use canvas to draw an image around a face within a
picture it doesnt and the picture is shown without any square. Im not
sure whether its an issue with Identifying the face or drawing a
square around the face. Any help would be really appreciated. Thanks
for your time.

The code is as follows

[code]



public class Activity3 extends Activity {

private static final int ACTIVITY_SELECT_IMAGE = 1;
private static final int GALLERY_ID = Menu.FIRST + 1;
public String mCurrentImagePath = null;
public int imageWidth, imageHeight;
public int numberOfFace = 5;
public FaceDetector myFaceDetect;
public FaceDetector.Face[] myFace;
float myEyesDistance;
int numberOfFaceDetected;
Bitmap bitmap;
public Canvas canvas;



private ImageView mImageView;



  /** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mImageView = new ImageView(this);
setContentView(mImageView);


}

// the canvas is below


public void onDraw(Canvas c) {
// TODO Auto-generated method stub

 canvas.drawBitmap(bitmap, 0, 0, null);

 Paint myPaint = new Paint();
 myPaint.setColor(Color.GREEN);
 myPaint.setStyle(Paint.Style.STROKE);
 myPaint.setStrokeWidth(3);

 for(int i=0; i < numberOfFaceDetected; i++)
 {
  Face face = myFace[i];
  PointF myMidPoint = new PointF();
  face.getMidPoint(myMidPoint);
  myEyesDistance = face.eyesDistance();
  c.drawRect(
(int)(myMidPoint.x - myEyesDistance),
(int)(myMidPoint.y - myEyesDistance),
(int)(myMidPoint.x + myEyesDistance),
(int)(myMidPoint.y + myEyesDistance),
myPaint);

 }
}


 //adds a menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);

menu.add(0, GALLERY_ID, 0, "Gallery");
return true;
}




//if gallery is chosen begin activity and allow user to select a
pic from the gallery

@Override

switch (item.getItemId()) {

case GALLERY_ID:

return true;
}

return super.onMenuItemSelected(featureId, item);
}


//when the user has selected an image and no error has been occurred
retrieve the image detect faces within the image and display the
image.

@Override

Right, you are supposed to get an exception with this. The NfcA tech
is for "low-level" access to ISO 14443 Type A tags (i.e. the
proprietary protocol as mentioned in ISO 14443-3.) Exchanging APDUs
happens on top of ISO 14443-4 data exchange protocol (which is
independend of whether you use type A or B by the way). The correct
tech for this is IsoDep.

Re: [android-developers] help: dont display Toast

[Kostya Vasilyev]

Are you sure this code actually runs, and calls Toast? Add logcat printouts
just before Toast to make sure.

[android-developers] Background service stay alive

[Eason]

Hi all,

I am trying to make several apps that can listen to system states all
the time and give responses when there is any event happens. For
example, a battery state widget, but my widget doesnt work after a
certain period of time. I found that the problem is, the background
service is not functioning after some time. So how can i solve that??

Say, for the battery widget, is that wrong to create a background
service and listen to the battery state (battery level, plugged to USB/
AC)? if else then what should i do to keep track with the battery
status?

Another app im working on is a music player, i created a background
service to allow user listen to music in background (even if the
application is closed), it is also a better way for me to manage the
life cycle of the media player in the app), but the service is gone
after some time and it annoys me.

Please help =[

[android-developers] Creating test application Dungeons

[grndvl1]

I am stuck at the part where you setup in app products.  per the
Google guide it says not to publish the example but lto leave it as a
draft.  Only problem is that the Developer Market won't let you
create in-App Products unless you publish it.  So which is it to
publish or not to publish or am I missing some trick?

Here is from googles guide:

Uploading the sample application

After you build a release version of the sample application and sign
it, you need to upload it as a draft to the Android Market publisher
site. You also need to create a product list for the in-app items that
are available for purchase in the sample application. The following
instructions show you how to do this.

   1. Upload the release version of the sample application to Android
Market.

  Do not publish the sample application; leave it as an
unpublished draft application. The sample application is for
demonstration purposes only and should not be made publicly available
on Android Market. To learn how to upload an application to Android
Market, see Uploading applications.
   2. Create a product list for the sample application.

  The sample application lets you purchase two items: a two-handed
sword (sword_001) and a potion (potion_001). We recommend that you set
up your product list so that sword_001 has a purchase type of "Managed
per user account" and potion_001 has a purchase type of "Unmanaged" so
you can see how these two purchase types behave. To learn how to set
up a product list, see Creating a Product List.

  Note: You must publish the items in your product list (sword_001
and potion_001) even though you are not publishing the sample
application. Also, you must have a Google Checkout Merchant account to
add items to the sample application's product list.

Re: [android-developers] In-app billing problem

[Kostya Vasilyev]

FWIW,

It's still not working for me - although it worked fine two or three 
days ago.


Same phone, same account, same modified Dungeons sample. In fact, I made 
no changes at all.


Now purchases for android.test.* are sent to Market, but never get any 
response. This is as if I was running the unsigned debug build on my 
test phone, but I'm running a signed release build. I even tried 
removing and adding back the test account in Market profile, no change.


They are presently rolling out per-country pricing for in-app billing, 
perhaps it's related.


PS - I don't see a way to set country-specific prices in my console. All 
I see is USD with no way to choose another currency. Their email said 
"available immediately".

Hi Ivan/Kostya,

I am having the exact same problem, and I am also seeing the same 
output regarding the GTalkService.

[android-developers] Re: Intent not received after application started

[nadam]

Make sure onNewIntent is overridden correctly. Should look like this:

@Override
public void onNewIntent(Intent intent) {
...
}

[android-developers] setPreviewCallbackWithBuffer issue

[chen ji]

Hi All,

I use Android 2.3 on NeuseOne.

Now, I use setPreviewCallbackWithBuffer to get preview callback and it
works well. But if I call takepicture, it will halt and I can not get
jpegcallback. But if I use setPreviewCallback, all things works well.
But as you know, its memroy is inefficient.

I just want to know what is the special thing before I call
takepicture when i use setPreviewCallbackWithBuffer .

BTW, my set preview call back code is just below:


 Size size = p.getPreviewSize();
callbackBuffer1 = new byte[ size.width * size.height * 3 / 2 + 1];
callbackBuffer2 = new byte[size.width * size.height * 3 / 2 + 1]; ;
mCamera.setPreviewCallbackWithBuffer(mPreviewCallback);
// if I use mCamera.setPreviewCallback(mPreviewCallback); it works
well

 mCamera.addCallbackBuffer(callbackBuffer1);
 mCamera.addCallbackBuffer(callbackBuffer2);

Thanks,

Ji
