[android-developers] Re: Where do we have to close the DB in a ContentProvider?
Hi all,
I have seen that if we use an AbstractSyncableContentProvider (other
providers like ContactProvider use it), a “close()” method is
implemented:
public void close(){
if(mOpenHelper != null)
mOpenHelper.close();
}
In this case, the helper seems to be closed (and also de DB), the same
helper that remains open in a ContentProvider. I can’t understand the
lifecycle of the ContentProvider without a method to release all the
things. Any ideas ?.-Thanks in advance.

I use a DBHelper class which extends the SQLiteOpenHelper class, and I

[android-developers] just renaming the file seems to help.
i have an incredibly weird issue -- I have an image button -- The button doesn't show up. If i copy the file in the drawable directory to "btn2" (the exact same file) and change the src in the xml to point to the new file "btn2", it shows up. if i rename it back to btn1, it doesn't show up again. then some time later, after adding some other buttons, btn1 reappears, but a later button I've added goes missing again. Then I do the same trick of copying the file to another copy, rename it, and change the src in the xml and it appears again!! very unusual. any ideas on what could be happening? tia. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Where do we have to close the DB in a ContentProvider?
Hi,
With an Activity there is no problem, the lifecycle is clear and we
have to realease all the resources in that method. The problem is that
I use this helper inside a ContentProvider. In this case there is
neither clear lifecycle (almost for me) nor a “close()” or “onDestroy
()” method where release the resources.

First, android:layout_centerHorizontal="true" is only valid if the parent is a RelativeLayout, and in your case, you are using LinearLayout. Second, android:layout_gravity="center_horizontal" might work, if you used android:layout_width="wrap_content". Since you used android:layout_width="fill_parent", you are saying that the TextView is to fill up all remaining space in the row, so there is nothing to be centered.

[android-developers] Re: ADC 2 - can I update my app after the 1. round
So this means that an app cannot be updated during the ADC? So if I discover a bug on 2nd September, I have to leave my app unpatched until mid-November? Even if it was going to be on TechCrunch the next day? Maybe it will be possible to release two versions of the app, one within the ADC which stays unpatched, and another one on the general Market which can be fixed?

[android-developers] problem using progress dialog with usertask
Hi, I have an application that downloads some content from the network, processes it and displays it. When any link is clicked, the user task(async task) is used to download and process the content and the content is shown in the new activity. I want to show a progress dialog until the content gets downloaded and processed. But when i call the progessdialog.show() method I am getting the following error. 'android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.binderpr...@435904d8 is not valid; is your activity running' I use the get method to get the result from the user task. I make the main thread to wait until the usertask completes its work. I know this is a bad way, but the normal handler does not work here.I think it is not good idea to start a new activity in the onPostExecute method. Please tell me how to do this. Thanks in advance.

Not necessarily. I'd hope that ADC2 apps are served to "judges" from a different location than the Market; if so, then you can update your Market version all you like. The updates just won't affect your ADC2 entry. Of course, here's hoping you don't find a serious bug on Sep 2, because your ADC2 entry will have to remain unpatched. :^/ String --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] System time update : NTP server
I find my droid doesn't update its clock itself, even if I ask it to automatically update it from network, I am still 2 min late since I ask it to automatically use network values (15 days ago). I need a better time for some data synchronization. So I dove into the Android API and I found the SntpClient class declared as internal, it seems to be used during the GPS localisation protocol. I extracted it. First, I was (and i'm still) unable to set up my Android device clock, the method SystemClock.setCurrentTimeMillis() is locked as described in the doc. Is there a way to unlock it or get round this to set the current time myself ? Second, when I was using the SntpClient class and doing some simple tests with it by getting time from a NTP server, I found that there was a difference between the real time and the received time (2 or 3s). It appears that the implementation of SntpClient doesn't look in accordance with the RFC 2030, after changing the SntpClient as described in the RFC, the time obtained was correct. long originateTime = readTimeStamp(buffer, ORIGINATE_TIME_OFFSET); long receiveTime = readTimeStamp(buffer, RECEIVE_TIME_OFFSET); long transmitTime = readTimeStamp(buffer, TRANSMIT_TIME_OFFSET); long destinationTime = requestTime + (responseTicks - requestTicks); long clockOffset = (receiveTime - originateTime + transmitTime - destinationTime)/2; long roundTripTime = destinationTime - originateTime - transmitTime + receiveTime; Only the clock offset value and the round-trip time where changed, the destination time was added as the time of arrival according to the device clock. I don't know which way the phone uses to update the time but I would be grateful to know.

Why do you think this? You might consider taking the approach of passing download instructions to the second activity (via extras) and having it display the progress dialog, arrange for the download, and dismiss the progress dialog. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Development Wiki: http://wiki.andmob.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Note that this creates new objects constantly that have to be garbage
collected later. Depending on the kind of application, it may be
better to just copy the values into a persisting array.

I have been using:
ConnectivityManager
connMgr=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info=connMgr.getActiveNetworkInfo();
return(info!=null && info.isConnected());
Are there scenarios where a NetworkInfo other than
getActiveNetworkInfo() might be connected?

[android-developers] Re: ADC 2 - can I update my app after the 1. round
The problem here is that you can only install one app with the same signature. So either the judging app will let you judge the app using the currently installed version, instead of downloading the "contest version", or it will not let you judge apps you already have installed. I hope they'll go with "use the installed one", even if it means a little bit of unfairness, seeing how apps will be judged based on different versions in some circumstances. Preventing users from judging applications they have installed would seriously punish popular apps. Both scenarios create unfairness, but the first one rewards good developers instead of punishing them. If I get some kind of confirmation on the second scenario, I'll have to submit my app under a separate signature. Otherwise, I'll just submit the one in the Market.

[android-developers] How to know the length of the character using Graphics?
Hi friends,
How can I know the length of the each character of word.
Actually, I am trying some thing like this:
I will show some set of lines on the screen. Later after some time, I
would like to set the color to each character in the line at a
frequent interval.
Here I am drawing the txt on canvas c:
p = new paint();
p.setAlpha(0x30);
p.setXfermode(new PorterDuffXfermode
(PorterDuff.Mode.SRC));
p.setTextSize(20);
p.setTextAlign(Paint.Align.LEFT);
c.drawText("some data",x,y,p);
here c and p are Canvas and Paint respectively.
Now I want to set the color to each and every character of the drawn
string.
How can I achieve this.
Please help me.
Thanks,
Manoj.

Hi, I am currently using sensors and I would like to know if I can slow down the sampling rate.

[android-developers] Security of application
Hi, I want to learn that how google android market provides security of application.That is, I realize that, when user downloads application, market downloads and install application atomically to phone. I am designing market and security is important issue so I wonder that how google achieve this? How is application installed phone? 1) Is the apk downloaded sdcard and deleted after installation? In the case of this how can market guarantee that when apk downloaded to sdcard, program finishes unexpectedly and installation- deletion of apk cannot be done? 2) Or installation is done from server? 3) I think that there exists security not to copy apk. how do they do this? Maybe they use phone id to install application, by this way even if anyone copy apk they cannot install it other phone? As I said above I am trying to desing market.

I can get it to work if I hard code the dimensions, but I'd rather do something a little bit more flexible.

[android-developers] Re: Security of application
The official way to do this is to put the .apk somewhere, and launch the app installer on it. This will copy the .apk into a secure place, analyze it, present the confirmation dialog (with the app's identity and permissions) to the user, and once confirmed proceed with the install. If your app is being built into the system, you can do a flow like market does: get the information about the app from the server first to present the confirmation dialog, then download the .apk and directly call the package manager to install it. This of course requires that the app be extremely careful about its implementation to avoid holes (ensure it has a secure connection with its server, is correctly parsing all relevant data out of the .apk on the server, is retrieving the .apk into its private storage before installing, etc). I believe the market also makes use of the download manager for downloading the .apk (which has access to the cache partition as a secure area for temporary download storage), which is not yet a public API but again if you are being bundled with a system you can use. That all said, there is nothing fundamental here that market is doing that regular apps can't. It is just able to do a different flow (permission check before download) because the system trust things built into it to directly install apps, and is able to use private APIs like the download manager instead of doing that work itself. Anyway, you probably don't want to download the .apk to the SD card, though from the system's perspective this is not a security hole, since it will copy the .apk into its own secure area before proceeding with the install.

[android-developers] Re: Where do we have to close the DB in a ContentProvider?
A content provider is created when its hosting process is created, and
remains around for as long as the process does, so there is no need to close
the database -- it will get closed as part of the kernel cleaning up the
process's resources when the process is killed.

[android-developers] ListView inside TabActivity
hi everyone,
i'm new in android, and i wanner put a "List" inside a TabActivity.
by google and coder's guide, my work out "direction" is to create a
"TabActivity" as MAIN and "ListActivity"
then add it in the "TabHost" and turn out code something like (below)
and fail:
"mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator
(this.getString(R.string.tab_search),getResources().getDrawable
(R.drawable.help)).setContent(new Intent(this, ListViewDemo.class)));"
I know i may need to spend more time on the BOOK and google for
android development, but i also feel that the resource for android is
quit scattered and not detail. (i'm a developer of C# for a few years,
and it's more easilier to search for information)
can anyone give me some information or links for this issue?
many thanks for any of your kindly help

Are you on Linux? You could try this.. From a terminal: killall -STOP emulator To pause it while not in use, and: killall -CONT emulator To unpause it.

[android-developers] Couldn't open fd for content://settings/system/ringtone
Hi,
I am trying to build donut on a reference device. I am using alsa lib
for audio drivers. When any app tries to write audio my device
crashes. From the logs first I saw that no audio files were created in
system/media. That I fixed by enabling the frame work sound makefile
to pick up default android sounds. After that, when any app like
incoming call or alarm is trying to play some default sound, it is
failing.
Before my crash, I see -
D/CallNotifier( 876): RINGING... (new)
D/CallNotifier( 876): onNewRingingConnection(): incoming
D/Ringer ( 876): ring()...
D/Ringer ( 876): mRingHandler: PLAY_RING_ONCE...

content://settings/system/ringtone
E/MediaPlayer( 876): Unable to to create media player
E/RingtoneManager( 876): Failed to open ringtone

Could this be the reason of my crash? It is actually crashing after
this in audioflinger when trying to AudioMixer and Resampler.
Any thoughts?

[android-developers] can anyone use adb after crc37 update (with g1)
hi there
last week i received the crc37 update for my g1. since then i was not
able to use my phone for developing. USB-Debugging is enabled but "adb
devices" doesn't recognizes the device. not shure whether it's my setup
or the new update. that's why i am asking here.
my setup:
debian sid, kernel 2.6.30-1-686
content of /etc/udev/rules.d/51-android.rules: SUBSYSTEM=="usb",
SYSFS{idVendor}=="0bb4", MODE=="0666"
is anyone of you successfully developing on the g1 with the crc37 build?
best regards,

[android-developers] Re: ADC2
I'm also searching for an answer to this question. We finished our app today and looked for the submission form, only to not find one. We are unsure if we should submit it to the Android Market or wait for the form. Anyone from Google want to help us out? Also, the fine print states that the apps cannot be updated once submitted, but implies they should be available for free in the Android Market. Does that mean that the Android Market will prevent updating of the application during the competition? Thanks!

[android-developers] Software Packaging Problem: How to create an Android installer (apk) ?
HI all, In Windows, we write "installer script", and user an "installer compiler" to generate an installer, let's say .inf for .msi/.cab and .nsi for NSIS.

[android-developers] ListView with multiple buttons, how do I detect which View the buttons were pressed in?
Hi all, I am writing a program where I need a ListView for which I am using a ListActivity. Each one of the views within the ListView has four buttons, (Off, Dim, Bright and On). Each one of these buttons is configured with it's own OnClickListener when I build the view. This part seems to work ok. However when I have say 5 Views each which has these four buttonns, I cann tell whether an off,dim,bright or on button was pressed but I cannot tell from which view it was pressed. So for example if my views are devices (Light, Heater and Kettle) I press an "on" button and i know an On button was pressed but how do I get it to tell me the On button for the Light was pressed? Any ideas on how to achieve this? Thanks, Matt --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] File created by app on sdcard can always be accessed by other apps
File created by application on sdcard can always be accessed by other applications, is that the fact ? For example, use camera capture pictures which will be saved to sdcard, and my application can access it. Tried more, I found File.createNewFile(new File(file_path)) create a file and set its access permission accroding to different file_path, e.g. if file_path is "/sdcard/DCIM/Camera/photo.jpg", photo.jpg is created on sdcard, and is set read&write by all applications. rw-rw- system system 16692 2009-08-21 16:25 photo.jpg if file_path is "/data/data/com.philip.camera/files/photo.jpg", photo.jpg will be the private file of the application com.philip.camera. -rw--- app_41 app_41 0 2009-08-21 17:03 photo.jpg it's interested that where android put the control of checking the path, I think it couldn't be in File.createNewFile, it's better for the standard library class to be unchanged, so could someone tell me where to satisfy my curiosity :) if above description has some errors , please let me know, thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] How to capture and save the image of Google Map(MapView)...
Dear Developers!
I'm trying to develop a map application which can save some part of
map inside a phone.
So, refering to the example of google developer site, I created my
activity that using the MapView class to display the location what I
want to see. It works.
And I attached some code to save that view into png format file using
Bitmap and Canvas classes. But it didn't work.
One image file was created but it didn't contain any information of
the map. I don't know the reason why those codes didn't work and
couldn't find any related information on the Web...
code is...
public class AndroidTest extends MapActivity {
MapView mapView;
List mapOverlays;
Drawable drawable;
HelloItemizedOverlay itemizedOverlay;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// build map and mark point
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapOverlays = mapView.getOverlays();
drawable = this.getResources().getDrawable
(R.drawable.androidmarker);
itemizedOverlay = new HelloItemizedOverlay(drawable);
GeoPoint point = new GeoPoint(1924, -9912);
OverlayItem overlayitem = new OverlayItem(point, "", "");
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
// copy MapView to canvas
Bitmap bitmap = Bitmap.createBitmap(400, 800,
Bitmap.Config.ARGB_);
Canvas canvas = new Canvas(bitmap);
mapView.draw(canvas);
// save it!
FileOutputStream fo = null;
try {
fo = this.openFileOutput("test.png",
Context.MODE_WORLD_WRITEABLE);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
bitmap.compress(CompressFormat.PNG, 100, fo);
try {
fo.flush();
} catch (IOException e) {
e.printStackTrace();
}
try {
fo.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Please, help!

[android-developers] how to get launchCount and execution time for applications
Hi,
i am developing application which displays the recently launched
application. I am able to get the list of apps using
ActivityManager.RecentTaskInfo.
Now i need to keep track of "how many times an application is
launched" and "also execution time of an application"?
In spare parts example, this is done. To achieve this they have used:
PkgUsageStats
public PkgUsageStats(String pkgName, int count, long time) {
packageName = pkgName;
launchCount = count;
usageTime = time;
}
But in the latest android SDK , PkgUsageStats is been replaced by
PackageStats
and it has only:
public PackageStats(PackageStats pStats) {
packageName = pStats.packageName
codeSize = pStats.codeSize;
dataSize = pStats.dataSize;
cacheSize = pStats.cacheSize;
}
So is there any other way to get the "launchCount"?
What is the alternative for this function?
Regards,
Shruthi

[android-developers] Contacts photos does not work after insert
Hello Friends.
I'm writing a small backup application for contacts and i encountering
some weird problems.
Firs of all I retrive data through the content resolver:
contentResolver.query(contentUri, columns, null, null, null);
where content uri and columns are both taken from Contacts.People,
Contacts.People.Phones, Contacts.People.ContactMethods, etc. So I
extract several sets of data and save them. Later on I'm making
restore operation:
for( HashMap row : data )
{
ContentValues values = new ContentValues();
for( String key : columns )
{
String value = row.get( key);
if( null != value && !"".equals( value))
{
values.put( key, value);
}
}
String masterKey = row.get( BaseColumns._ID);
if( null != masterKey && !"".equals( masterKey) )
{
try
{
contentResolver.delete(
Uri.withAppendedPath(
contentUri, masterKey),
null, null);
}
catch(Throwable t)
{
t.printStackTrace();
//do nothing, to not to crash
}
}
try
{
contentResolver.insert( contentUri, values);
}
catch(Throwable t)
{
t.printStackTrace();
}
}
Such operation done for each ContentProvider I retrieved data at
backup.
I'm not backuping Contacts.Photos, becouse I don't want to do that.
But next, strange thing happenning, when i try to attach photo to a
contact in Contacts application. First of I select a contact i wish to
modify. Then clicking to add icon. Selecting photo, cropping it. And
it appears near the contatc name in contact editing activity. But
after I click "Done" and android says that chages were successfully
changed, icon just dissappears like i never added it to a contact.
And nothing helps after this restore, I tried rebooting my phone,
deleting all contacts, deleting all contacts programaticatlly and all
this doesn't helps. The only thing that helps is factory data reset.
This problem both happens on emulator and on g1 phone. Later i had an
idea so i've taken contacts.db file from fresh emulator, where photos
feature were still working and saved it. Then i performed backup-
restore operations. And compared the databases. They were identical.
And still photos weren't inserting anymore. And this probleblem also
happens wether I had any photos added to contacts before backup or all
contacts were without photos. So I'm kinda desperate now, becouse I
don't know what to do. And I hope someone here will help me =) So any
help would be appreciated.
Thanks in advance =)

Look up the Great Circle Calculation. That will provide you with the method for finding x within a given y radius.

[android-developers] how to reuse existing activity?
If my current activity stack is A->B->C, I want it to be like A->B->C- >A, which the top A is the same instance as the first A. I tried several approaches, but couldn't get what I want. 1. Before calling startActivity, set intent flag as Intent.FLAG_ACTIVITY_REORDER_TO_FRONT, which makes the stack like B->C- >A 2. Trying activity A's launch mode as "singleTask" or "singleInstance", still couldn't get expected stack. It looks like the activity stack per task cannot have duplicate one. Any solutions will be appreciated. Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: sharing database across applications
why no accessing contacts.db by ContactsProvider directly? If any changed , using ContentObserver to receive changes.

[android-developers] Re: Security of application
Thanks Dianne. That was a nice piece of information. A couple of questions/comments. 1. Is there any way to retrieve information from the .apk on the server side other than using the aapt tool ? 2. Just curious, why did you say "you probably don't want to download the .apk to the SD card".
