[android-developers] Is it possible to send a log file via mms or email without user interaction?

[D.]

I know an android app can send an sms without the user's interaction,
but what about an mms? I think i've read that the intent used to send
an email brings up the email client for the user to decide which email
app and account to use(which is understandable), but how about mms?

I'm simply looking to send a text file to another phone or email
address via my app without the user's intervention. Can I use mms? Any
other ideas? Thanks.

[android-developers] What purpose does the top-level FrameLayout serve?

[adamphillips12]

I was watching the Google IO videos and Romain mentioned quite quickly
something about the top-level FrameLayout being needed by the OS? That
is the one directly below the getDecorView().

Can I get a more extended explanation of why it is needed? It is not
locked in anyway, we are quite able to remove it, if it was that
critical I would assume it would come already built-in to the
decorView itself, why is it only added as a public subview? I would of
thought the point of the decorView was to handle OS related items,
such as the soft keyboard.

I have not seen any adverse effects to its removal, so I'm fairly
curious to know what it does? I can see clearly what it does with a
title bar but without one, I do not.

[android-developers] Where the resize/scaling of video is happening inside surface flinger

[sreedhar b]

Hi,

I am not able to understand from the surface flinger code flow, where
exactly the resize/scaling for video is performed
inside the surface flinger??

Also, if anybody can give some data flow as from where the resize parameters
source width, source height, destination width, destination height are
 passed from the upper layers (may be from the video view widget or the
opencore) to the surface flinger?

help greatly appreciated.

Sreedhar

[android-developers] Re: Developing on different platforms

[Roman]

Hi Andrew,

I prefer to work with a Linux like environment. The Mac and Ubuntu
environment is pretty good for Android development. If you also work
on framework level and have to build a complete platform build then
Ubuntu and Mac should be preferred.  Windows might be fine for
application development and of course you can run Cygwin but why not
right away going for Ubuntu or Mac.

If you don't want to spend money on a Mac book then consider to run
VMplayer with a Ubuntu.iso image. On one of my machines I have this
setup and it is pretty fast.

Application development only:

Windows is fine but  Mac or Ubuntu preferred


Framework development:

Mac or Ubuntu

Platform builds and porting efforts

Ubuntu

[android-developers] Re: Creating new projects in eclipse

[Roman]

Try to create a new workspace folder. When you have an existing
Android app then use the import functionality for creating a new
Android project.

In general before spending too much time on a messed up Eclipse setup
consider to download Eclipse again which might be faster ...

[android-developers] Re: [AppWidget ] How to get widget object from appwidget

[clybe cai]

Tanks for your kindly support,JS.
Now I put the onclickactions to a BoardcastReceiver,then
bind the  BoardcastReceiver to a intent.If I want to do some operations when
click the button, I  need to create a PendingIntent object to wrap the
intent,and use RemoteViews.setOnClickPendingIntent(int buttonID,
PendingIntent pi) to bind the button with the button actions.

  final ComponentName receiverName = new ComponentName(context,
  MemoBroadcastReceiver.class);

  Intent deleteMemoIntent = new Intent(
  MemoBroadcastReceiver.DELETE_ACTION);
  deleteMemoIntent.setComponent(receiverName);
  Bundle deleteBundle = new Bundle();
  deleteBundle.putInt("KEY_APPWIDGETID", appWidgetID);
  deleteBundle.putLong("KEY_PRIORITY", priority);
  deleteMemoIntent.putExtras(deleteBundle);
  PendingIntent deleteMemoPending = PendingIntent.getBroadcast(context,
  0, deleteMemoIntent, PendingIntent.FLAG_CANCEL_CURRENT);
  views.setOnClickPendingIntent(R.id.delete, deleteMemoPending);

I do not paste all my code. The thread start is in OnClick on some
button as below:

public void onClick(View v) {
if(!thumbnailThread.isAlive()){
thumbnailThread.start();
}

Also has other code to change the jpg file for different image.

But now after check the link 
http://android-developers.blogspot.com/2009/05/painless-threading.html,
which i guess is written by you. I use AsyncTask instead. And it works
fine. Thanks for your great blog.

Best Regards

Yes, the digital compass in the G1 is self calibrating, but you have to make
figure 8's or similar to make it do it, this isn't something you can do in
software, the Android OS has magnetic field projections for the earth and if
the current reading falls outside a specific range either something is
artificially influencing it, such as the magnetic field in metals or
electromagnetic fields caused by electronics and cars etc, or it needs
calibration.

[android-developers] Re: How to support drag and drop on listview.

[Craig]

Would it be too much to ask to get ListView dnd built into the
framework api? It seems like a common requirement, but a total pita to
implement every time. A couple of extra listeners like
onRequestStartDnD() and onRequestFinishDnd() would be adequate for a
lot of use cases.

(I know...patches welcome :)

[android-developers] Re: Intercepting an incoming/outgoing email

[Dianne Hackborn]

I wouldn't expect it to "mature" much in this regard.  At least not any time
soon.  First, the Gmail app is owned by Google, and by its nature is pretty
self-contained and unlikely to rely on any generic platform e-mail mechanism
you could intercept.  (Think of it the same way as the user using gmail in
their web browser on a desktop.)  Second, I don't think there is any
interest in any time soon having some kind of e-mail content provider or
back-end storage that mail apps would use, so the platform's generic e-mail
app will remain fairly self contained, and anyway I think it is something
that individual devices are likely to significantly customize or outright
replace.

I suspected as much with the Google Search "widget".  Thanks for
clarifying.  And the results of the grep for @RemotableViewMethod
annotation are very useful.

Great responses to every question!  Thanks Jeff!

I was mostly aiming at the internal email apps.  Seems the only way to
do it is to create an email application with the functionality I want
built in.  I think I'll wait to see if the platform matures enough,
first. :P

[android-developers] Re: Why is onActivityResult() called before onResume()

[Dianne Hackborn]

I don't think one way is necessarily more logical from the other.  The basic
reason is that generally when you get a result, this is coming from an
activity you had launched, so it is delivering it to you before you are
resumed.  So we give it to you before resuming so that you can update your
UI however you want, and onResume() is thus the last thing that happens
before the UI is shown and has all of the information it needs (including
whatever results are coming in) to do so.

[android-developers] Re: Intercepting an incoming/outgoing email

[Dianne Hackborn]

No there isn't.  There is a generic e-mail application that ships with the
platform, the special Gmail application from Google, and who knows what
other e-mail applications that other manufacturers can include or users can
download from the market.  There is thus no generic platform concept of
interacting with outgoing e-mail.

Yes it does.

If that's the case then I'll try using the
WindowManager.getDefaultDisplay() methods and replaced the fixed
values - this was currently for development purposes.

[android-developers] Re: Intercepting an incoming/outgoing email

[Anonymous Guy]

Anybody?  This is a basic thing to do on other platforms (well, other
than iPhone which can't have any background processes :P ).  Without
it being possible to intercept/change email messages, it limits what
the platform can actually accomplish.  And if it's a "security issue",
see Blackberries -- they are the most secure, yet still allow this for
third-party developers.  If a user puts an application on the phone,
they implicitly trust that application.

[android-developers] Re: RelativeLayout in Java code with inflate and custom view - position issues

[Romain Guy]

Does your activity have a title bar? Is the status bar visible when
your activity is on screen? If so, the problem comes from the fact
that you manually set the RelativeLayout's size to 480 px. With a
title bar and a status bar, this will end up being outside of the
screen.

By the way, you should NOT do what you are doing here. Using fixed
size and positions will not work with future Android devices.

[android-developers] RelativeLayout in Java code with inflate and custom view - position issues

[Tane Piper]

Hi there,

I have a custom view that I had to write for a large scrollable image,
as the images are larger than the size of the screen.  Before, I had
tried to do it by putting the image into a ScrollView but that of
course didn't work.

The view itself is within a RelativeLayout within the activity and at
the bottom of the screen I have two buttons that are used for
navigation and at the top a TextView with a caption for the activity
(the main header is already being used here for instruction).

In my below code, I've checked the Hierachy Viewer to confirm all the
elements are loaded and in the Activity I can see the TextView,
however it overlays the ZN5ScrollView area and below the image I just
have a blank area of the size defined rather than my buttons.  For the
bottom navigation, the Hierachy Viewer is saying the absolute_y of the
bottom navigation is 480.

I'm wondering if anyone can help with my layout code here to get this
working correctly?

How it should be is:

Bottom navigation is 50px high, ZN5ScrollView is 365px above the
navigation, and the TextView takes up the rest of the area at the top:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle("Tap Image To Return");

/* We need to get the inflator for the bottom navigation */
LayoutInflater inflator = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
gestureScanner = new GestureDetector(this);
res = getResources();
bmp = BitmapFactory.decodeResource(res, 
R.drawable.zn5_overview);

/* We need a root layout for this */
RelativeLayout layout = new RelativeLayout(this);

/* We now need to load the bottom navigation */
RelativeLayout bottom_navigation = 
(RelativeLayout)inflator.inflate
(R.layout.bottom_navigation, layout);
RelativeLayout.LayoutParams bottom_nav_params = new
RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
bottom_nav_params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
bottom_navigation.setLayoutParams(bottom_nav_params);


HomeButton = (ImageView) bottom_navigation.findViewById
(R.id.btn_home);
NextButton = (ImageView) bottom_navigation.findViewById
(R.id.btn_next_session);
HomeButton.setOnClickListener(Navigation);
NextButton.setOnClickListener(Navigation);

ZN5ScrollView = new ZN5ScrollView(this, bmp, IMAGE_WITDH,
IMAGE_HEIGHT);
RelativeLayout.LayoutParams ZN5ScrollView_params = new
RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, 365);
ZN5ScrollView_params.addRule(RelativeLayout.ABOVE,
R.id.bottom_navigation);
ZN5ScrollView.setLayoutParams(ZN5ScrollView_params);

layout.addView(ZN5ScrollView, 1);

TextView textView = new TextView(this);
textView.setText("WHAT'S COOL");

RelativeLayout.LayoutParams textView_params = new
RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
textView_params.addRule(RelativeLayout.ABOVE, 1);

textView.setLayoutParams(textView_params);

layout.addView(textView, 2);

setContentView(layout, new RelativeLayout.LayoutParams(320, 
480));
}

Any help on this would be much appreciated!

[android-developers] Why is onActivityResult() called before onResume()

[MrSnowflake]

I ran into a problem of resource allocation and release using the
activity lifecycle functions when waiting for an activity to return a
result. I suspected that onResume() was going to be called before
onActivityResult() but it's the other way around.

Why is this? Isn't it more logical for onResume() to be called first,
so we can get a hold of resource we need to evaluate the result from
the sub activity in onActivityResult()?

I'm just wondering.

[android-developers] 2 mediaplayer using one surfaceview

[sbw.android]

hi,
I want to play 2 videos one after one minimizing delay between each
video.
so I created 2 mediaplayer, one playing the current video and the
other preparing to play the following video.

 the 1st video is played correctely but I couldn't get the video track
of the second video. only sound without any error.
can somebody help?
thanks.

this is my source code :

use files on a web server. that's why I need to prepare the second

[android-developers] Re: Questions about how animations work / are implemented

ViewGroup simply calls invalidate() after drawing its children if

As long as I can get the device and do a little prototyping and it

are no ties to a specific carrier to test the application on a real

[Deren]

Okay, thanks! But what about the question regarding invalidate()/
postInvalidate()? Because I tried to experiment with scrolling, and
simply calling invalidate() from computeScroll() wasn't sufficient, I
had to call postInvalidate, even though computeScroll() runs on the UI
thread?

[android-developers] Questions about how animations work / are implemented

[Deren]

I've been looking around in the framework source and I can get my head
around some things. For instance, in the ScrollView, the animated
scrolling is done by using computeScroll(). To make the screen redraw
(and thus call computeScroll() again), postInvalidate() is used. Why
is that one used, instead of a regular invalidate-call?

Secondly, I wonder some things about the Animation framework. I know
how a ViewGroup is responsible for animating the children (modifying
the Canvas and so on), but what drives the animation, i.e. what makes
the screen redraw over and over again? In the case of the ScrollView,
it's the call to postInvalidate() made from computeScroll(), but what
is it in the case of an Animation?

[android-developers] Re: Sortable ListView

[Jeff Sharkey]

The Music app can reorder a playlist of songs, and its source code is
available.  It might take a little bit of digging since it's
intertwined with Music-specific code, but here are the important
parts:

TouchInterceptor, which is a custom ListView:

http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/TouchInterceptor.java;hb=cupcake
http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=res/layout/media_picker_activity.xml;hb=cupcake

TrackBrowserActivity, which uses TouchInterceptor.  In particular,
mEditMode is what enables the reorder mode:

http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/TrackBrowserActivity.java;hb=cupcake

Hope this helps.

[android-developers] Re: which width and height for a 2*1 cell widget? 160*100? Bug in Widget?

[Jeff Sharkey]

Using the following equation yields:

Minimum size in dip = (Number of cells * 74dip) - 2dip

146dip = (2 * 74dip) - 2dip
72dip = (1 * 74dip) - 2dip

The reason for the odd math is because the same dimensions are used
when inserted in landscape mode, which has different cell sizes on the
default home screen.

[android-developers] Re: Widget Unresponsive after Opening/Closing

[Jeff Sharkey]

Are you sending a full RemoteViews update each time?  (The AppWidget
framework only keeps the last RemoteViews sent, and reapplies it when
needed, such as after a screen rotation.)

For example, if you only set the PendingIntent once, and have a second
RemoteViews update that doesn't include it, the PendingIntent will be
lost when the screen is rotated.

[android-developers] Re: How to disable Buttons on a Widget

[Jeff Sharkey]

> Is it possible to disable a button on a Cupcake desktop widget?

Not directly, but you could send a widget update that swaps out the
drawable used and clears the PendingIntent.  Or, keep two buttons in
your layout, and visible/gone them as needed.

The Google Search bar on the desktop looks and feels like a widget,
but it isn't a real widget.  It lives directly in the Launcher app,
which is how it does things like auto completion.  Other
AppWidgetHosts are free to include their custom elements like this:

The allowed methods are simply marked with the @RemotableViewMethod
annotation, here's a quick grep across the Cupcake tree:

[android-developers] Bug in IntBuffer.put() when using direct buffers

[djp]

In a process of switching from indirect to direct buffers for OpenGL
geometry specification I've found a problem with the following
function in java.nio.IntBuffer class:

IntBuffer put(int[] src, int off, int len)

this function is supposed to do a bulk transfer of int data from the
given array starting at the specified offset. It should be an
optimized version of the following code:

for (int i = 0; i < len; i++) {
buffer.put(src[off + i]);
}

The problem is that the bulk transfer method does not work properly
with non-zero offset when the IntBuffer is created from a direct
ByteBuffer. I'll try to demonstrate the problem using a code sample:

ByteBuffer directBuffer = ByteBuffer.allocateDirect(size).order
(ByteOrder.nativeOrder());
IntBuffer intBuffer = directBuffer.asIntBuffer();

// does *not* work with offset > 0
intBuffer.put(data, offset, length);

// does work with offset > 0
for (int i = 0; i < length; i++) {
intBuffer.put(data[offset + i]);
}

I'm using G1 with an official 1.5 firmware.

Regards,
David

You can't access the actually-inflated layout from your app because it
exists entirely in another process.

You can't setOnClickListener() directly, because the target View lives
in another process.  If this were allowed, the other process would be
executing your code as itself, which is a security hole.

Right, you can't pass the appWidgetId through a PendingIntent extra

[android-developers] Re: New Google Maps app - new Intents URI schemes?

[JP]

Clarification: I am looking for the Intents URL schemes that may or
may not be available to call the new functions in the Google Maps app,
from outside of an app. This is similar to the websphere when opening
calling a web server with a RESTful GET query. So this is *not* an API
call from within an app.

[android-developers] Re: How to save the "view" to "image file" ?

[Brian Smith]

Two questions...

1) (out of curiosity) What does the ability to take snapshots have to
do with the ability to design a game for Android?  Games usually put
things on the screen, not the other way around.

2) Are you wanting to do this from your code, or just to have
screenshots for advertising/publishing?

I don't know how to do it from code, but the Android SDK does provide
a way to take screenshots from an emulator or connected device.

http://developer.android.com/guide/developing/tools/ddms.html

If you're using Eclipse for Android development, the DDMS functions
are available in the DDMS context (assuming you've installed the
Android plugin).

[android-developers] Re: Upgrading to sdk 1.5

[ndatta]

To add to the above: on Windows, the current working directory is
included automatically in the search PATH. Thus when you type
"android" from inside the tools directory, Windows searches the
current directory by default and runs the android tool. On Mac/Linux
however, the current working directory is not automatically included
in the search path. Thus you have to tell the system that the android
tool is in fact located in the current directory (assuming that you
have already changed to the tools/ directory). Thus you need to type
"./android" instead of just "android".

[android-developers] Re: Android WebView - handling orientation changes

[Brian Smith]

It has to reload the page every time, by default, because the default
action for an activity dealing with a configuration (including
orientation) change is for it to be destroyed and restarted.  That can
be overridden, though, by specifying an android:configChange attribute
for the activity in your manifest file.  My uses of WebView so far
don't involve any forms where keyboard input would be required, so
I've been able to specify "orientation|keyboardHidden" for that
attribute without having to do anything special with config change
notifications.  The WebView widget handles re-wrapping text and images
based on view size.

Running apps on Android doesn't depend on carriers, unless you want to test
data networking, in any case I'd get something other than the HTC Dream/G1
for AT&T if you want data cause AT&T EDGE is so slow it's not funny... The
HTC Magic supposedly does 900Mhz which I think AT&T runs 3G over... so will
the i7500 and no doubt countless other devices once they start shipping...

[android-developers] Re: Search context with type-to-search?

[Brian Smith]

Figured this one out... along with overriding onSearchRequested(), I'm
also overriding startSearch() and inserting the required app data in
the 2 activities where I need it if it's not there and local search is
specified.  It may be redundant but, at the same time, logic suggests
that the default key handler in android.app.Activity should call
onSearchRequested() in the first place for local searching, in case
it's overridden.  Oops :-)

[android-developers] Re: Able to use T-Mobile G1 without contract for application testing?

[dindin]

I don't have T-Mobile but AT&T. I want to get an unlocked Android
Phone (thinking of the new Samsung i7500 or the G2). Can I use that as
a development device to test my applications? Will it even work on
another GSM carrier?

Thanks.

[android-developers] Re: start call with intent from browser

[nleiptv]

Hi,

I am quite a newbie to Android, so chances are there is an easier way
to do this, but what I propose should work.
Have a look at this project from Android's SVN:
http://apps-for-android.googlecode.com/svn/trunk/Samples/WebViewDemo
It displays how to use a web view (if you want: a browser view that
you can integrate in your own application) and how to call JavaScript
from the activity that embeds it. Furthermore it shows how to call
from JavaScript into your Activity by registering a JavaScript
interface with the web view to serve as the callback. You could attach
JavaScript code to the link you want the user to press in your web
view, then that JavaScript code could call into your application and
that could initiate the call.

Say you had written a JavaScript interface class like this:

public class CallDispatcher{

  public void call(String number)
  {
 String dispatchURI = "tel:" + number;
 // the code to fire the intent to start the call
  }
}

then in the activity you embed the WebView in you would call:

mWebView.addJavascriptInterface(new CallDispatcher(),
"jsCallDispatcher");

and in the JavaScript of the link you would call:

window.jsCallDispatcher.call("+00161384950");


I think that should work.

Cheers,

nle

[android-developers] Features of SDK 1.5

[Andy_Metia]

Hi Developers!
My software team is looking to develop mobile apps on the Android
platform for our clients and they have asked me to do some research on
the platform.  I'm not a dev so apologies if some of the questions are
a little simple!!

What are the key features of SDK 1.5?  i.e. what works well and is an
improvement on 1.1, what needs to be added and what plain doesn't
work?

Can you help??!

Thanks!

[android-developers] Playing video as a raw resource

[JP]

I'm writing a program which requires that a video be packaged with
it.  The only way I know of doing this is by adding the video to res/
raw/, which coincidentally renders the video useless.  I've looked all
over the web and the consensus seems to be you can only play streaming
video, or video from a file.  In the emulator if I attempt to play the
video through the method used here ( 
http://developer.android.com/guide/topics/media/index.html
), all I get is audio and a black screen.

I've attempted to use VideoView as well, and the same thing occurs,
audio but with a black screen.  There must be a way to package video
with your application without needing an SD card, or having to stream
the file and have the video actually play.  In the words of Google, I
would like to create a "seamless" experience.  :)

Any help is greatly appreciated!

[android-developers] Re: How to play video file in android.

[yangzw]

MediaPlayer does support streaming, but in this case, setDataSource
should have Uri as the input, rather than a String input just like you
used in your code. Hope it helps.

[android-developers] Native MediaPlayer plays audio but not video (3gp format)

[dglushko]

Hi,
I have the following native source code that is supposed to display
video.
It plays 3gp file ok and I can hear the audio, but the video is not
shown.

Code:

// Global surface initialized elsewhere
extern sp g_surface;

void media_player_test(void) {
MediaPlayer *mp;

mp = new MediaPlayer();
if(mp == NULL) {
return;
}

mp->setDataSource("/data/local/video.3gp");
mp->setVideoSurface(g_surface);
mp->prepare();
mp->start();
}

End of code

In Java I manage to play video with almost the same implementation.
The only difference I can see is that Java code calls setType() for
the surface holder.
I can't find a matching operation for setType() in native code.
Is it important?

One more thing, I tried with and without listeners/callbacks, but the
video still doesn't play.

Thank you.
David

[android-developers] RTSP and RTP streaming on the Cupcake-upgraded

[pierre]

Hello all,

I am trying to test RTP streaming on the Android G1 dev phone with no
success.
I used to do that successfully before to upgrade to Cupcake. But now
the same test doesn't work anymore.
Is it supposed to work?

Here is a detailed description of the test:

1) The device is the G1 dev phone upgraded to Cupcake.
2) It is connected via WiFi
3) The RTSP session is started with the VideoView activity from the
sample code (http://developer.android.com/guide/samples/ApiDemos/src/
com/example/android/apis/media/VideoViewDemo.html). The only
modification consists in specifying the RTSP URL for the path string.
4) The Darwin Streaming Server version 5.5.5 is used as an RTSP
server.
5) The mp4 file which is streamed complies with the specifications in
http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/media/VideoViewDemo.html
. It is hinted.
6) Wireshark is used to monitor RTSP exchanges. The OPTIONS and
DESCRIBES commands take place normally. Then nothing more.
7) The following error appears in the Android error Log:
E/PlayerDriver(   35): Command PLAYER_INIT completed with an error or
info PVMFFailure
8) A popup windows says: "Cannot play video. Sorry, this video cannot
be played".

Notes:

1) The same test was successfull with the 1.1 Android version before
upgrading to Cupcake.
2) There is a web server collocated with the RTSP server. The same
file streams OK over http with the web server.

Thanks in advance for any clue.

[android-developers] How to get the audios' _id list from db

[Androlux]

Hi, All,

Now, I wanna get the audios' _id in the same folder, except
the audio files in the sub-folder; do you have any suggestions?
For instance, there is a folder /sdcard/A, which contains some
songs and sub-folder B(that is, /sdcard/A/B), and there are some song
files exist in /sdcard/A/B; now, how to get the _id of the files in /
sdcard/A except those in /sdcard/A/B?
Thanks in advance!

[android-developers] Android WebView - handling orientation changes

[Glenn]

Hi,

Just started working with the webview. The issue is performance
following rotation. The WebView has to reload the page, which can be a
bit tedious.

What's the best of of handling an orientation change without reloading
the page from source each time?

Thanks

Glenn
