[android-developers] android voice route

Hi all:
 
    I am developing an apk to get and send the audio stream from Socket(via BT spp)，it can work as a Bluetooth Walkie Talkie now,
    then,i want to put the audio string (PCM 8k) to the voice call when i get it from Bluetooth.
    1、android system, how can i put the audio stream to the phone call connection that the other end can hear?
    2、During a voice call, how can i play Background music ? is there any interface in android can mix the voice to call?
 
 
best regard

    Hello,
    For making compatible in all device you shold use the "dp" in height and
    width instead of "sp" and if text size is small then you can define the
    size like "14sp" it will compatible in all device. and space between text
    and image if you want then give the margin right of text so it will
    automatically give the space.Is it your requirement?

    I've been trying to convert an iPhone app, built with phonegap/jqtouch, to
    Android and I've hit some issues. I'm pretty ignorant about eclipse and
    java so go easy on me. I've two questions..
     
    I got the app working in eclipse and on my htc desire s, it was a bit slow
    and unresponsive but at least it worked. Then I discovered the app wouldn't
    work on android devices (as far as I can tell, testing is a biatch) running
    OS 3 and over (the htc is 2.3). It stops working on the homepage screen by
    failing to load the tabbars. My only guess is that its somehow realtaed to
    internet connection, as on the iphone version, the tabs would only load
    when the connection was fine. Apart from that, I just know enough about
    eclipse/android to even know what the right questions to search for. Any
    advice on how to track down the problem?
     
    The second question is how to improve the perfomance. - its very sluggish.
    I knew it would be bad but its worse than. I'm in the process of trying to
    minify and strip out as much as I can but are there any other suggestions
    about how to improve performance? One really annoying thing is that on
    certain transistions from one page to another, the new page loads up, then
    the old page flashes up for a second before going back to the new page -
    has anyone encountered this before?
     
    thanks!

    Hi guys,
     
    I'm attempting to get into NFC on Android by communicating with a custom
    PN532 device, however I'm a little confused as to my options and the
    Android protocol.
     
     
    - NFCIP-1, is it possible to place my device as a target into this mode,
    for Android to automatically detect and communicate with to load an app or
    can this only be done in card emulation mode (i.e. does NFCIP-1 have to be
    actively triggered)?
    - What's the easiest to use card emulation mode for the sake of data
    format simplicity? (get an NDEF file over to the phone as simple and easy
    as possible that it will automatically act upon)?
     
    Any help/advice is very much appreciated,
    Many thanks

    Hi lads,
     
    I'm running into trouble trying to make the software keyboard pop.
    I've already read all the posts related to that but unfortunately none
    helped me.
     
    I tried toggleSoftInputFromWindow, showSoftInput,
    getWindow().setSoftInputMode() with all possible combinations and all
    possible flags. I don't have an EditText, so I even tried to create a
    fake one. I made the call from different listeners to make sure it was
    not a thread related issue. I tried to delay the thread a bit.
     
    Still, those methods always return false and therefore the keyboard
    doesn't show...
     
    BUT! Everything works as expected as soon as I minimize the
    application (by pressing Home) and restore the application. From then,
    the keyboard shows up without any problems.
     
    Any clues?
     
    Phil.
     
    PS : My phone has a hardware keyboard.

    Hello, I was just wondering if there was any way for a developer to receive
    and distribute promotional codes, keys, or licenses for a paid app once it
    is on the app store. If not, what would be the best way for a developer to
    distribute copies of the paid app while still having a license or key check
    of some sort?

    I am creating an app. it consist of 2 screen graphics (.jpgs) and an .mp3
    file.
     
    Everything is ready to go as far as content, I just can't make it work!
     
    Basically on screen 1 there is a play button, when pressed it should switch
    to screen 2 and infinitely loop the mp3 file. If the play/stop is pressed
    again, the mp3 stops and screen one loads.
     
    That's it!
     
    I am having a hard time getting the basics done for some reason, It would
    take me ages to code but I am hoping someone here is bored and maybe has an
    mp3 player type code that could be slapped together with my graphics... let
    me know if you can help please. I'm making this app as a suprise for my GF.
    :)

    I wanted to log some existing information without installing an app in
    android. I wanted to log the connected wifi name with timestamp. This
    hardly takes 5-6 lines of code. But, I dont want to create a separate app
    or service. I want this to be added as inbuilt module in kernel and flash
    the phone. But, I am quite not sure where would be the best place to
    include this. It would be helpful if anyone can give me some ideas. There
    is a class that gives the wifi name. All i wanted to do is log it with
    timestamp. HOw to go about it? Thank you in advance.

    Hi,
     
    I'm currently making a SDK for a payment gateway, however I'm having some
    problems.
     
    The project setup is supposed to be:
    *Library Project*
     
    DAO Classe
    SDK
    Server connectivity class
     
    *Application*
     
    UI
     
    Using the above Library project
     

    And from the library project I want to send some images (drawables) for
    example images for what credit cards are available for the payment. These
    credit cards can change depending on different settings so they need to be
    sent dynamically to the application using the SDK.
     
    I'm currently importing the library project by selecting the library
    project under properties in Eclipse (I need to do it with a Jar or
    something to make it closed source but one problem at a time).
     
    Now the problem I get is that I get a NullPointerException when I try to
    set the drawable from the SDK to an ImageView in the app. Here's some code:
    DAO Class from the SDK (this class extends Application):

     
    > case (MASTERCARD):
    > this._logo = getResources().getDrawable(R.drawable.mastercard_securecode);
    > break;
     
     
    This is in the constructor. And then there's a simple getter method to
    access the _logo varible, which is a Drawable. The R.drawable i refer to is
    a ressource located in the Library Projects res folder.
     
    In the application I then want to be able to do something like:
     
    > ImageView img = (ImageView) findViewById(R.id.imageView);
     
    img.setImageDrawable( DAOObjet.getLogo() );
     

     
    So that whoever implements the SDK is able to decide how the UI should be
    implemented.
     
    However doing it this way I'm as said getting a NullPointerException on the
    line that serves the Drawable from the SDK (eg the line quoted above in the
    switch/case statement).
     
    I have a feeling I'm loading the ressource in a completely wrong way, but I
    dont know.
     
    Could someone assist me with this? That would be much appreciated!

    I am attempting to test the update() method of my custom content
    provider. I receive a null pointer exception due to the getContext()
    method call within the update() method being null. To alleviate this
    issue I have attempted implementing
    http://stackoverflow.com/questions/6516441/why-does-androidtestcase-getcontext-getapplicationcontext-return-null
    to no avail. My test class looks like the following:
     
    public class AddressContentProviderTest extends
    ProviderTestCase2<AddressContentProvider> {
    public void testInsert() {
    Uri CONTENT_URI = Uri.parse("content://" +
    AddressContentProvider.AUTHORITY + "/address");
    AddressContentProvider addressContentProvider = new
    AddressContentProvider();
    ContentValues initialValues = new ContentValues();
    boolean isException = false;
    Uri returnURI = null;
    initialValues.put("country", "USA");
    initialValues.put("region", "test");
    initialValues.put("city", "Jacksonville");
    initialValues.put("state", "FL");
    initialValues.put("zip", "32258");
    initialValues.put("province", "test");
    initialValues.put("geo_location_id", "");
     
    returnURI = addressContentProvider.insert(CONTENT_URI,
    initialValues);
     
    assertTrue(returnURI != null);
     
    }
     
    The insert method looks like the following:
     
    @Override
    public int update(Uri uri, ContentValues values, String where,
    String[] whereArgs) {
    SQLiteDatabase db =dbHelper.getWritableDatabase();
    int count;
     
    switch (sUriMatcher.match(uri)) {
    case ADDRESS:
    count = db.update(ADDRESS_TABLE_NAME, values, where, whereArgs);
    break;
    default:
    throw new IllegalArgumentException("Unknown URI " + uri);
    }
    getContext().getContentResolver().notifyChange(uri, null);
    return count;
    }

    I'm a Chinese and sorry about my English is not good .
     
    That is my problem:
    How can I get two angel?
    angel 1. angel between device surface and the level
    angel 2. azimuth of device surface (azimuth of the projection of device
    surface normal vector)
     
    I read the document on developer.android.com which part about class
    Sensor.Event , and have several questions.
     
    1. Is sensor of type TYPE_ORIENTATION really physically exist ?
    In the document , it told me that :"use getRotationMatrix() in
    conjunction with remapCoordinateSystem() and getOrientation() to compute
    these values instead."
    (this is it
    http://developer.android.com/reference/android/hardware/Sensor.html#TYPE_ORIENTATION
    )
    Since I can compute the orientation values by other two sensor values , why
    is there a redundant sensor exist?
     
    2. I need to compute the normal vector of device surface?
    I want to get the angel between device surface and the level .
    In my mind , I put device in the world coordinate system : Y point to North
    , X point to East , Z point to sky
    Then for the two angel I want , I only need to get the normal vector
    of device surface .
     
    3. How can I get the normal vector?
    Whether I use sensor of type TYPE_ORIENTATION or use getRotationMatrix()
    plus getOrientation() , the values I can get are Azimuth Pitch and Roll (
    differences are only on sign and 3 angels is in degree or radian ).
    I tried several different way to rotation vector (0,0,1) with this 3 angels
    to get the normal vector , but all of them seems do not work .Help me ,
    make is work please. T T
     
     
    Thank in advance.

    Last I heard, Java 7 and the SDK weren't getting along with each other
    very well (if at all). Is this still the case? Or is Java 7 ok now?

    Hello,
    if you want to just differenciate the button images then use the one xml
    and define the two image one for default and one for press and set that xml
    as background of button.It will solve your problem ok.

    I need to delete some images from my application dir (inside
    Pictures/Application).
    Though the image gets removed, when I call for the managedQuery() to fill
    again the grid, the image that I just removed is retrieved.
    I'm trying to force a scan on the application directory, but it's not
    working. Some code below:
     
    deleting files:
    http://pastebin.com/tQe8s7mm
     
    sanning directory
    http://pastebin.com/ixuz8xsC
     
    Do you guys have any ideas of what may be causing this behavior?
    Thanks in advance,
