[android-developers] Re: Send Email Automatically
Thank you for the quick answer Dianne. It confirms that I'll just have to
include another implementation of SMTP into my app.
Though I still think it would be nice if could set up an Intent, loaded with
the proper information in an attached bundle that would specify the email
account, the account authentication, and the message body. Which would be
handled by an application that the user had configured as the default email
handling application without user intervention. Hmmm, actually this might make
an interesting little project to continue my Android education.
Understand it's not possible at the moment though, through standard
resources..

have the permissions set properly. So I would expect that I would also need
to set permission to allow sending email as well.
There is only one way SMSs can be handled. On the G1 there are two e-mail
clients built in to the system, one of which can have multiple accounts. You
CAN NOT send an e-mail without the user being involved, period, because you
simply have no way to know how that e-mail should be sent.
If you want to send an e-mail, you need to have the code for doing so in your
app, and have the user specify the account information for it.
I have been poking around a bit in the source code and found this in the
stock Android email app:
package com.android.email.mail.transport;
/**
* This class handles all of the protocol-level aspects of sending messages
via SMTP.
*/
public class SmtpSender extends Sender {
public static final int CONNECTION_SECURITY_NONE = 0;
public static final int CONNECTION_SECURITY_TLS_OPTIONAL = 1;
public static final int CONNECTION_SECURITY_TLS_REQUIRED = 2;
public static final int CONNECTION_SECURITY_SSL_REQUIRED = 3;
public static final int CONNECTION_SECURITY_SSL_OPTIONAL = 4;
private Transport mTransport; 53 String mUsername; 54 String
mPassword;
..
/** Allowed formats for the Uri:
* smtp://user:passw...@server:port CONNECTION_SECURITY_NONE

* smtp+ssl://user:passw...@server:port CONNECTION_SECURITY_SSL_OPTIONAL
*
* @param uriString the Uri containing information to configure this sender
*/
public SmtpSender(String uriString) throws MessagingException {
...
Which seems to have public methods to send email.
You are looking in the e-mail app. There is nothing public here at all. It is
just internal implementation of the application. It doesn't matter if it makes
a class public in its internal implementation, it is still internal, and
nothing you can use.
As I understood the
philosophy behind building Android apps, which is to reuse
public Intents and methods to allow the scarce available memory to be
leveraged as much as possible.
Yes, there are intents for using parts of an application that they want to
allow others to access. There is no standard intent for "send an e-mail
without the user being involved," and I don't expect there to be such a thing
any time soon if at all. Some specific e-mail application may define its own
intents to use for that, but this would be specific to that app, so you would
need to know about it yourself. (And if multiple apps were to support this,
you would still need to have the user involved to decide which app to use, and
possible which account in that app to use.)
So the question is: Can we use the existing code to send email in the stock
Android email app? Or is that sort of thing frowned upon?
It's not possible.

[android-developers] Re: ERROR/MediaPlayer(1066): setDataSource called in state 128
I agree that it's most likely me doing something wrong. It looks like when the audio file is about to end the state of MediaPlayer gets changed in the native code. And maybe reset() doesn't take effect during this process while setDataSource(), invoked right after, finds player not to be ready. Maybe Android music app creates MediaPlayer every time or synchronizes the invocations somehow. I wonder whether the situation I described is possible and if it is whether you can advise on the solution. I can create MediaPlayer all the time, but I'm afraid to use too many resources doing so. I'm usually reluctant to creation of unnecessary objects. I really appreciate your help and apologize for my not very deep knowledge of the player functionality.

changing my output file extension from ".3gpp" to ".audio"
-Ben
final String path = "/sdcard/recording" + System.currentTimeMillis() +
"_" + (int)(Math.random() * 1000)+ ".audio";
final MediaRecorder mr = new MediaRecorder();
mr.setAudioSource(MediaRecorder.AudioSource.MIC);
mr.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mr.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mr.setOutputFile(path);
mr.prepare();
mr.start();
//stop recording after 10 seconds
Timer t = new Timer();
t.schedule(new TimerTask() {
public void run() {
//stop recording
mr.stop();
mr.release();
}
}, 10*1000);

[android-developers] Re: android.permission.GET_ACCOUNTS
We unfortunately left most of the permission string constants in the SDK, even for ones protecting private APIs. So something being there doesn't mean there is an API for it.

Hello Richard,
Thanks very much. This is very helpful. I am using the same SDK
version but in this case I was not using the SDK.
I had been experimenting with LocationListener too. I had been using
onLocationChanged.
Again, Thanks.

[android-developers] Re: Animation on a view doesn't 'stick' in reality
Okay I've figured it out. I would personally consider this a bug but not sure if this is how it's meant to be. Basically in onAnimationEnd I had to loop over all children inside the viewgroup (and children of children) and set their visibility to GONE/ INVISIBLE and the buttons stopped getting touch events after animation ended. And then onAnimationStart I had to set their visibility back to VISIBLE. Shouldn't setting visibility/focusability/enabled state etc on the parent ViewGroup apply these down to its children as well (especially the visibility part). Since the parent view became invisible, which is fine, but the children view didn't (well internally) and thus were intercepting Touch events eventhough the view as a whole was not visible. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Thanks Romain - I did this (and the completion listener) neither of these work. Basically the 'AbsoluteLayout' ViewGroup slides out of the screen but then when you tap on the are where that view once was, the old buttons apparently still get tapped (eventhough completely invisible). If I've 'translated' a view, shouldn't it stay where it is and not get the kind of focus/clicks it's getting right now? I tried setEnabled(false), setVisibility(View.GONE) -- nothing seems to work. The 'invisible' view still gets touch events and buttons are being pressed from the view that got slid away. Am I doing something wrong? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

How can i create objects on the map, which (after klicking on them) are able to show their names and also that specific arrows to jump to the next object, like in Google Maps.

Well, the built-in music player is open source: http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=tree In principle, you could make a sleep-timer patch and submit it: http://source.android.com Admittedly, there is a learning curve for making changes to the source code, more so than with many open source projects, due to the unusual build environment and the unusual patch submission process. I haven't climbed that curve myself. Another possibility would be for you to create an application that let users configure sleep timers and, when the timer elapsed, broadcast an Intent that confirming applications would pay attention to and honor. You might partner with OpenIntents.org, as this seems like their sort of application, and you might be able to help get some prominent third-party applications, such as some music players, to honor your sleep-timer Intent. This requires as much people skills as coding skills, though, to convince other developers to follow your sleep-timer lead. There are probably other ways to go about this as well -- those are just two off the top of my head. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Hi I'm using a TranslateAnimation to slide a ViewGroup in and out of screen. However after the animation slides the view out, the transparent view is still 'clickable' in the same place.

I have the SDK version 1.1r1 on my machine, and Actually don't see

Anyway, I assume you want to cell tower location and such. Try
creating a listener, and then registering your listener with the
TelephonyManager.
Start by giving your application the following permissions:
android.permission.ACCESS_FINE_LOCATION
android.permission.ACCES_COARSE_LOCATION
Then, create your listener:
// implement both phone state listener and location listener.
public class PhoneSignalListener extends PhoneStateListener
implements LocationListener{
/**
* @param signalStrength signal strength in ACU.
*/
public void onSignalStrengthChanged(int signalStrength){
float signalPercent = ((float)signalStrength)/31f * 100f;
SignalStrength.setSignalStrength(signalPercent);
SignalStrength.setSignalStrengthASU(signalStrength);
}
public void onCellLocationChanged(CellLocation cellLoc){}
public void onLocationChanged(Location loc) {}
public void onProviderDisabled(String arg0) {}
public void onProviderEnabled(String arg0) {}
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {}
}
And then you register it with TelephonyManager. In your application's
main activity (Activity.onCreate()):
public class MyActivity extends Activity{
public void onCreate(Bundle savedInstanceState) {
TelephonyManager telManager = (TelephonyManager)
this.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(new PhoneSignalListener(),
PhoneStateListener.LISTEN_SERVICE_STATE |
PhoneStateListener.LISTEN_SIGNAL_STRENGTH |
PhoneStateListener.LISTEN_CELL_LOCATION);
}
}
As the phone location changes you get the information delivered,
wrapped in a pretty package with a bow, to the Phone signal listener.

[android-developers] Re: Permissions to install other apps...
That's why apps can't install other apps without the user being involved. I was addressing the first part of the original poster's request, being able to download and run Dalvik code in your own process. In that case the new API will let you do this, though of course you are running the other code as -yourself- so taking responsibility for anything it does.

[android-developers] Re: list of request codes - their names and values?
But this is a RingtonePreference - I'm not starting the activity from code. RingtonePreference is defined in preferences.xml (which defines how the Preferences are laid out). All I know is that the request code - not the *result code* - that is returned is 100. I need to know the name associated with that value 100...

[android-developers] Re: OOM errors during inflation
Hi Romain,
Thanks a lot for your answer: this should definitely help fix the
issue! In fact, I
wouldn't be surprised if a lot of posts regarding OutOfMemory issues
are caused by
the same problem.
However, I think many hours of bug hunting could have been prevented
if this
'recycler' point was mentioned in the API docs for Adapter. My own
thinking was that
"convertView" was basically the View that was previously generated
(for the item
above the current one in the list), and if you wouldn't use it, it
would be garbage
collected.
Take the following from getView:
"convertView - The old view to reuse, if possible. Note: You should
check that this
view is non-null and of an appropriate type before using. If it is not
possible to
convert this view to display the correct data, this method can create
a new view."
It actually talks about "this method can create a new view", but to me
it's not clear
that a reference to each returned View is kept somewhere in the
ListView. How could I
have known this? You may have written part of this code, so it's
probably very
obvious to you, but to the outside developer, it's not.
The point about how you MUST reuse the convertView should be stressed
much more
clearly in the API docs, in my opinion. As well as the point about the
recycler.
Alternatively, maybe the Adapter implementation could be changed so
that it always
only keeps one reference of a particular type of View. Why should it
keep multiple
references to the same View type, if it's only possible to provide a
single one as
convertView?
Either way, I'm very happy to finally understand the inner workings of
the Adapter,
and it will help create more robust code.
Kind regards,
- Niek

[android-developers] Re: Permissions to install other apps...
Would not it be somewhat dangerous to allow apps is /data/app folder to install other applications?? An app can just create an infinite loop in which downloads applications which do not require any permission and keep on installing them and fill out the memory space?

[android-developers] More Than One Instance of Application
Hello, Is there a way to prevent the user of opening more than one instance of my application? For example: User clicks on App and opens it. The user clicks on the home button. (the app is still running in the background) The user clicks on (not the menu button, but the button above it in the homescreen), and then opens the application again. Does it open the same instance, or does it create another one? If it does create another one, how can I prevent it from creating another one, and just opening the existing instance?

any ideas?

[android-developers] Re: sample source code for beginner
Hi Tony. No, you are not stupid, although you would be if you didn't listen to my as-usual perfectly awesome advice. I recommend you look at the Android tutorial at http://developer.android.com/guide/index.html, and for UI layouts, see http://developer.android.com/guide/topics/ui/declaring-layout.html . Or you can go straight to the sample code at http://developer.android.com/guide/samples/index.html . The layout sample code is at http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/view/index.html . There are of course many other good tutorials out there as well.

[android-developers] Re: How to login to the root of Android Dev Phone 1?
Hi Gavin, Giving full rights to everything in /data is not a very good idea. I don't think chmod supports -R on android so it might not be possible at all. The easiest way to remove everything related to your application would be to uninstall it from "manage applications". Then when you'll run it from eclipse it would be just as a fresh install. Another solution is to connect your phone with USB to your desktop (there is a driver for windows, on Linux it should work by default), run adb shell, su to become root and rm /data/data// databases/ to delete the db. You could also use sqlite3 to only drop tables and not delete the entire db. Regards On Apr 9, 6:30 pm, Gavin Aiken wrote: > Hi Guys, > > I'm having the same issue.

[android-developers] Re: ERROR/MediaPlayer(1066): setDataSource called in state 128
I am one, and the error you posted indicates you called setDataSource while the MediaPlayer was in the 'playback completed' state. It could be a race condition in the framework, but since I have never seen this problem occur with the Android music app, I'm inclined to think it's a problem with your code. As a workaround, you could create a new MediaPlayer when you want to play something new.

[android-developers] ListView row not receiving highlight with ImageButton in row
Hi This must be something very simple but I've tried almost everything and still can't get this to work. Basically I've made a custom LinearLayout view with a TextView and an ImageButton to be used as a row for a ListView. The moment I use an ImageButton tapping on the row does not highlight the row any more. Moreover, I can't 'focus' the rows using the trackball, nor can I set focus on the button. If I remove the ImageButton and replace with an ImageView, the Row highlight/selection works. How can I get row selection/highlight along with ImageButton highlight at the same time? Many thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Intent to Trigger a Dialog Only
I want to expose a portion of my app with an intent that will only display a simple dialog box for system setting. The only way I currently know how to do this is to have an activity that accepts an intent. In the activity I don't use setContentView. I only create and show the dialog. The activity is finished after you press OK from the dialog. This is kind of okay, but the activity shows as a black backdrop under the dialog, until you press OK which brings you back to the last application. I'd like to just be able to show the dialog on top of the calling Activity. Any idea on how this can be done?

Thanks Al. I downloaded it. Works great. However, I couldn't connect to the network.

[android-developers] Re: Incorrect clip rect in onDraw()?
setText() invalidates the TextView entirely and when two invalidates
happen in the same UI event (as it is the case in your code), the
invalidate region becomes the union of the two original invalidate
regions.

[android-developers] Re: OOM errors during inflation
There is no memory leak in LayoutInflater. While this is never a
proof, it's something we never encountered in
any of the apps we wrote. Also, the Android team works very hard to
plug all the memory leaks we can find
and when we tell developers to use less memory it's when we're pretty
sure that the APIs that seem to be
causing the memory leak are not responsible.
For instance, in your case you are basically saying that if you
inflate views until you run out of memory, you
run out of memory. Every View created by the adapter is kept by the
ListView in a 'recycler'. That recycler is
used to provide the adapter with a convertView whenever possible. That
means you MUST reuse the
convertView.
If you need views of different types in the list, just use the
appropriate APIs: Adapter.getViewTypeCount() and
Adapter.getItemViewType(int position) (see
http://d.android.com/reference/android/widget/Adapter.html). If
you implement these methods correctly, ListView will manage several
recyclers and always give you back the
correct convertView.

[android-developers] Re: layout_weight is inconsistent for horizontal and vertical orientation.
I already explained this to you :) The weight is meant to distribute the remaining empty space amongst the views. In your case, there is NO remaining empty space since all your views are "fill_parent" (i.e., they are as wide and as tall as their parent.) In this case, LinearLayout *subtracts* the overflowing space from the views. So if a child has a weight of 2 it will be shrunk twice as much as a child with a weight of 1.

[android-developers] Subclassed ImageView does not draw in Gallery View
I am subclassing the ImageView class and adding to the Gallery View.
But, nothing seems to get drawn in the expected location; though I can
fling through the Gallery list. I added an image from a resource, and
it shows up correctly in the Gallery.
Any idea on why this may be happening?
Here is the code I am using:
public class CustomCanvas extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Gallery g = (Gallery) findViewById(R.id.gallery);
g.setAdapter(new ImageAdapter(this));
}
private class CustomImageView extends ImageView {
public CustomImageView(Context context) {
this(context, null);
}
public CustomImageView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CustomImageView(Context context, AttributeSet attrs, int
defStyle) {
super(context, attrs, defStyle);
}
protected void onDraw(Canvas canvas)
{
canvas.drawColor(Color.BLUE);
}
}
private class ImageAdapter extends BaseAdapter{
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return 2;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView,
ViewGroup
parent) {
if (position == 1)
{
ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.icon);
return i;
}
else
{
CustomImageView w = new CustomImageView
(mContext);
w.invalidate();
return w;
}
}
private Context mContext;
}

There is only one way SMSs can be handled. On the G1 there are two e-mail
clients built in to the system, one of which can have multiple accounts.
You CAN NOT send an e-mail without the user being involved, period, because
you simply have no way to know how that e-mail should be sent.
If you want to send an e-mail, you need to have the code for doing so in
your app, and have the user specify the account information for it.

You are looking in the e-mail app. There is nothing public here at all. It
is just internal implementation of the application. It doesn't matter if it
makes a class public in its internal implementation, it is still internal,
and nothing you can use.

Yes, there are intents for using parts of an application that they want to
allow others to access. There is no standard intent for "send an e-mail
without the user being involved," and I don't expect there to be such a
thing any time soon if at all. Some specific e-mail application may define
its own intents to use for that, but this would be specific to that app, so
you would need to know about it yourself. (And if multiple apps were to
support this, you would still need to have the user involved to decide which
app to use, and possible which account in that app to use.)

[android-developers] Re: is there best way to passing array buffer between Activity in same application
Really really do not pass large amounts of data (such as bitmaps) through an Intent. This data must be marshalled over to the system process, held there the entire time the target activity can be in use, and marshalled back over to the application process when the activity is being launched. You can certainly put data in globals, but you need to be aware you will lose this if your process gets killed (such as if the user presses home to leave your app, goes and does something else, and memory is needed that causes it ot be killed). Then when the user returns to your app, your data will be gone. I would probably suggest that you store the data in a file.

[android-developers] Re: Activity can't be displayed from a notification
Have you tried just launching the activity from elsewhere to see if it
actually works at all? (For example you can use the am command to launch an
activity.)
Fwiw, you don't want to use the Theme.Activity.Alert style. Actually that
shouldn't even be part of the SDK, so I'm not sure how you are using it at
all. (And if you are not using the SDK, you should not be here, but in
android-porting.)

[android-developers] Re: WebView - issues with back button
I tried this approach and it worked out fine.
I followed step 3 and
I used WebViewClient implemented my own
shouldOverrideUrlLoading()
>From within this method
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent i = new Intent( Intent.ACTION_VIEW, Uri.parse(url) );
i.addFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
try
{
view.getContext().startActivity( i );
}
catch (Exception e)
{
Log.e("Problem", e.getMessage());
}
return true;
}
This enabled me to get clicks and also handoff the URL to a different
WebView.
If you see issues with this approach, pls let me know.
Thank you.

[android-developers] Updating a built-in application - data preserved?
Hi, There was a discussion on this earlier (http://groups.google.com/group/ android-developers/msg/59f5c1ad46e6b94c) - could someone confirm whether the functionality of updating a built-in/system application with a app published on the Android Market will be available in cupcake? If I have an agreement with the device manufacturer/operator to pre- install my application on the device, I want to be able to publish an update to the application later via Android Market. I will have access to the same certificate as was used to sign the original application that was bundled with the device.

[android-developers] Permissions to install other apps...
Hi, We are a team of Android developers and we are facing a serious problem for quite some time. Our app (a game client) is designed in such a way, that once it's installed it can be used to download games from a game server. In order for the downloaded games to work, they have to be installed and launched by the client. The problem is that the client has no write/update rights for the / data/dalvik-cache directory, unless we specifically execute the chmod 777 command for that directory. Setting the android.permission.INSTALL_PACKAGES permission in the client's manifest file also doesn't work. After reading countless forums where other people have complained about the same problem, we would like to know when this issue is going to be resolved. Apparently the code for this feature already exists (the DexFile class of the so called "cupcake" release) but it hasn't been released yet. What's more frustrating is that the Android team points out that all Android apps are equal, that system apps are equal in rights to custom apps. Obviously this is not the case. If the client game app is installed in the /system/app the problem described above is solved. System apps have the right to dynamically install other apps. Regular apps (installed in the /data/data folder) do not. Is this issue going to be resolved anytime soon? Will the "cupcake" DexFile class going to be present in the next release? This is a rather urgent problem since we are waiting for this new functionality in order to continue development.

[android-developers] Modular resources under eclipse
I'm developing a family of applications that have a lot of functionality in common. In eclipse, I have a "core" project with all the base functionality. Each individual application project has this core project on its build path, so it can use the functionality offered by the core project. This works fine for code: the android eclipse plugin packages all code in the .apk files of the application projects, so each application apk file is then a self-contained application. However, I also want to reuse the resources that are used by the core project, like layouts and images. The "core" project is an android project with resources, but these resources are not packaged automatically in the application projects. In a perfect world, the "core" resources would be merged in the application project seamlessly, even updating R.java in the application project when a core resource changed. I understand this is probably too much to hope for, and I might end up juggling two "R" classes in my application: the core R in one package and the application R in another package. Outside of eclipse I can see how this might work: I package both sets of resources in the apk file, and with two AssetManager (and Resources) instances manage the two sets of resources. Or maybe I use ant to first create a single distribution by merging the core and application project files into a single directory, and then build the apk like you would do when there is only a single project. Is there some way to trick eclipse into packaging both "core" and "application" resources files into one .apk file? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] layout_weight is inconsistent for horizontal and vertical orientation.
Hi everybody! I have played around a bit with the xml files for creating layouts and can't explain the behaviour of layout_weight when using it in a LinearLayout that has orientation="vertical" When creating a layout that is horizontal everything follows the documentation, that a child would get more space if it's has the highest value. But the following code for vertical orientation, give more space to the item with lowest weight. http://schemas.android.com/apk/res/android"; android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> And the question is: Is this a bug or just a feature that maybe need more documentation?

[android-developers] ADP1 device not listing by adb devices command in Ubuntu.
Hi,
I am trying to flash images to ADP1 G1 Android device. For this, I
have tried to Setting up a Device for Development as follows:
1. Login as root and create this file: /etc/udev/rules.d/50-
android.rules.
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
2. Now execute:
chmod a+rx /etc/udev/rules.d/50-android.rules
But, still I am not able to list the device on giving adb devices OR
fastboot devices.
Again I have tried as below steps.
1) Make an "android" group and add yourself to it.
2) Found out the Vendor ID of your device using lsusb. The vendor ID
is the number before the semicolon.
$ lsusb
Bus 005 Device 005: ID 0bb4:0c02 High Tech Computer Corp.
...
3) Create a rules file as root.
# cat - > 70-android.rules
BUS=="usb", SYSFS{idVendor}=="0bb4", GROUP="android", MODE="0660"
-D
4) # /etc/init.d/udev restart
But, still no luck for me to list the device on giving adb devices OR
fastboot devices.
Can anyone help me to list the device to flash the images onto it.
Thanks & regards,
Lumit

[android-developers] setOnKeyListener does not works with MapView
Hi all,
I am trying to write a map application based on the MapView, and I
need to handle the UP/DOWN/LEFT/RIGHT keys.
At first, I tried to implement with setOnKeyListener, please take a
look at he following code.
mapView = (MapView) findViewById(R.id.mapview);
// set on key listener
mapView.setOnKeyListener(onKeyListener);
// Inner class for OnKeyListener
final private OnKeyListener onKeyListener = new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
boolean ret = false;
Log.i("SuperMap", "event.getAction()=" + event.getAction());
Log.i("SuperMap", "keyCode=" + keyCode);
if (event.getAction() == KeyEvent.ACTION_DOWN) // key pressed
down
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_UP:
Toast.makeText(SuperMap.this, "UP",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_DOWN:
Toast.makeText(SuperMap.this, "DOWN",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_LEFT:
Toast.makeText(SuperMap.this, "LEFT",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_RIGHT:
Toast.makeText(SuperMap.this, "RIGHT",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
default:
// do nothing here
ret = false;
break;
}
else {
// do nothing when key released or multiple keys
pressed at the
// same time
ret = false;
}
return ret;
}
};
It compiles OK, but does not works (there isn't any log in Logcat,
seems it does not receive any key press event).
Later, I tried to use the onKeyDown() function, so no setOnKeyListener
() is needed, and all I need is just the following function which
override the one in the super class.
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
boolean ret = false;
Log.i("SuperMap", "event.getAction()=" + event.getAction());
Log.i("SuperMap", "keyCode=" + keyCode);
if (event.getAction() == KeyEvent.ACTION_DOWN) // key pressed down
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_UP:
Toast.makeText(SuperMap.this, "UP",
Toast.LENGTH_SHORT).show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_DOWN:
Toast.makeText(SuperMap.this, "DOWN",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_LEFT:
Toast.makeText(SuperMap.this, "LEFT",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
case KeyEvent.KEYCODE_DPAD_RIGHT:
Toast.makeText(SuperMap.this, "RIGHT",
Toast.LENGTH_SHORT)
.show();
ret = true;
break;
default:
// do nothing here
ret = false;
break;
}
else {
// do nothing when key released or multiple keys pressed at the
// same time
ret = false;
}
return ret;
}
This time, it works, but I am confused.
According to my understanding, they are almost the same.
Anybody knows why?

[android-developers] ADP1 device is not listing by adb devices command in Ubuntu.
Hi,
I am trying to flash images to ADP1 G1 Android device. For this, I
have tried to Setting up a Device for Development as follows:
1. Login as root and create this file: /etc/udev/rules.d/50-
android.rules.
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
2. Now execute:
chmod a+rx /etc/udev/rules.d/50-android.rules
But, still I am not able to list the device on giving adb devices OR
fastboot devices.
Again I have tried as below steps.
1) Make an "android" group and add yourself to it.
2) Found out the Vendor ID of your device using lsusb. The vendor ID
is the number before the semicolon.
$ lsusb
Bus 005 Device 005: ID 0bb4:0c02 High Tech Computer Corp.
...
3) Create a rules file as root.
# cat - > 70-android.rules
BUS=="usb", SYSFS{idVendor}=="0bb4", GROUP="android", MODE="0660"
-D
4) # /etc/init.d/udev restart
But, still no luck for me to list the device on giving adb devices OR
fastboot devices.
Also my adb command is not responding for a long time
Can anyone help me to list the device to flash the images onto it.
Thanks & regards,
Lumit

[android-developers] API Demos APK not running.
Hi, I am trying to run API-Demos.apk in the zoom board. But it seems, the APK is not getting installed properly. I have compiled the CodeBase using Eclipse, and source is been taken from Android SDK 1.0. Please let me know, how can i run the application on zoom board.

[android-developers] MVC model state change requires creating an Intent?
Hi, I have a main activity class that launches a couple of my subordinate activities from a tabHost. Periodically (actually when I receive an incoming message on a socket), I want to inform the subordinate activities that application state has changed so that they can refresh their views. In Swing I could wire this together using something like a PropertyChangeListener. As far as I can see, the Android design philosophy requires creating an Intent and broadcasting to (as far as I can tell all) other activities that are running. This strikes me as overkill considering that I'm only trying to notify my own views of a model change. Am I missing something?

[android-developers] Re: How could add a new src folder into android src for compiling?
You could do this very easily in eclipse. Just go to the project properties and choose java build path view.In the source tab add a folder that you want to set as souce folder. Is zte developing android phones? I come from china ,too.

[android-developers] WebView - issues with back button
Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application. Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page. After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application). Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: OOM errors during inflation
Hi guys,
I've read several posts from developers having OutOfMemory issues, and
a lot of them seem to be related to lists. I'm having a similar issue,
and the root of the problem seems to be a memory leak in the inflation
process.
The problem is particularly tricky to track down, because as of yet it
seems impossible to get a view of part of the heap (where the bitmaps
reside, and possibly other objects), as also mentioned by Ward and
others.
I created a small demo, so hopefully some Google engineers (Romain,
Dianne) can look at this, and either point out to me what I'm doing
wrong, or fix a possible memory leak in the inflation process in the
Android framework. I'm sure a lot of people would be very thankful if
this issue got resolved, as it often results in sudden crashes of the
app, without a clear reason. I must say it's disappointing to read the
standard: "use less memory" reply from Google to a lot of these posts,
as it seems to be worthy of further investigation.
Here's the demo, and the resulting logcat log with some peculiarities
contained within.
http://www.coffeebreakmedia.com/android_heap_issue.zip
A small explanation: it's a very simple list implementation with a
ListAdapter. It works fine if the list rows are inflated just once (by
re-using the convertView), but I purposely commented out two lines of
code:
// if(convertView == null) {
convertView = inflater.inflate(R.layout.list_row,
parent, false);
// }
This is to ensure that for each row, the XML is inflated again. In
this demo, this would be completely unnecessary and a big waste, but
in a real life a similar scenario happens when you have a list with a
few different types of rows (e.g., a different xml is used for the
header of a set of items, which use their own xml). In that case,
sometimes the convertView will be of the wrong type, in which case you
have to inflate another one. Obviously, this would then happen less
often than in this demo, but this only postpones the issue: eventually
you'll run into the same problem as is demonstrated here.
To test the demo, simply open the project in Eclipse (you can use the
emulator, but it also happens on the G1), and follow these
instructions:
1. Completely scroll down the list as fast as you can (all the way to
Item 199), and then back up again.
2. Keep doing this until you scrolled down & up about 5 times, while
watching the LogCat.
Eventually, you'll start getting errors such as these:
04-08 12:15:03.380: ERROR/dalvikvm-heap(345): 13824-byte external
allocation too large for this process.
04-08 12:15:03.380: ERROR/(345): VM won't let us allocate 13824 bytes
Keep scrolling! And you'll see this after a few more ups & downs:
04-08 12:16:48.589: DEBUG/dalvikvm(345): GC freed 0 objects / 0 bytes
in 169ms
04-08 12:16:48.589: INFO/dalvikvm-heap(345): Clamp target GC heap from
16.003MB to 16.000MB
04-08 12:16:48.589: INFO/dalvikvm-heap(345): Grow heap (frag case) to
16.000MB for 24-byte allocation
04-08 12:16:48.810: INFO/dalvikvm-heap(345): Clamp target GC heap from
18.003MB to 16.000MB
Apparently, the 16MB heap is used completely at this point, which
seems rather wasteful considering the simplicity of the application in
question.
After still more scrolling, you'll get errors such as this:
04-08 12:17:01.700: ERROR/dalvikvm-heap(345): Out of memory on a 708-
byte allocation.
