[android-developers] Writing to External SD
I have an issue with writing on external SD... Writing on the external SD as Google puts it is not difficult with Environment.getExternalStorageDirectory(). However I want to make a difference for my users so they can choose to either backup their data to the 'on device' external memory and the 'SD Card' the user put in the device (if any). If both are available the Environment.getExternalStorageDirectory() method always gives me the SD memory build in the device. If only the SD-card is present I have the SD-card reference. Currently I solved it by letting the user manually enter the location URI of the SD-card, but that's not user-friendly at all so I'dd rather have a way to just let them choose between 'On device storage' and 'SD-card storage' and let me retrieve the URI myself... Is there a clean way (or maybe a library) to do so? Kr, Dirk -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] PendingIntent launched from widget causes onActivityResult to not be called
I do indeed need that. What I'm trying to do is: 1) I have a widget with a button, on the button I want to put the PendingIntent that I showed in my first post. 2) Then when the user presses that button, an action happens (something is started), and I want to change the PendingIntent on the button to something new (another activity and different extras) in order to create a 'stop' button 3) When the stop button is pressed I again change the PendingIntent to the one from step 1 So to achieve that I found out that I have to use a PendingIntent, but or the id of the pending-intent I use the id of the widget (because per widget the user needs to be able to start the process). And I do that I have to use the FLAG_UPDATE_CURRENT, so the pending intent is updated (and not removed or whatever) when the user presses the button. A second reason to use the FLAG_UPDATE_CURRENT is to not loose the PendingIntent when it's fired once. Whit this I mean when the user presses the button, he can still cancel his action (in the activity that opened he just presses the back button of the device). But doing this with the PendingIntent.FLAG_ONE_SHOT will make that when the user presses again that button on the widget my activity is no longer executed. Or should I do this another way...?

Re: [android-developers] PendingIntent launched from widget causes onActivityResult to not be called
It always worked find to just pass the extras (in fact it's not only the widget ID that i'm passing, there is some other stuff in there to..). It since the launced activity starts another activity for result it doesn't work anymore... So I guess using the extras or the data element won't make a difference. I even tried to launch the activity without passing anything and still my onActivityResult method is not reached... So what I currently do is nothing more than this (so without any extras): Intent intent = new Intent(ctx, activity); PendingIntent pendingIntent = PendingIntent.getActivity(ctx, widgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT); So then what do you mean with create different actions? Do you mean to create different pendingIntents (so with a different requestCode, something like start + widgetId and stop + widgetId) or do you mean to create two different activities (cause that is whay I already have, a start- and stop-activity)?

Re: [android-developers] PendingIntent launched from widget causes onActivityResult to not be called
I solved my own issue... I was setting some flags on my intent: Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS | Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK; But when using the FLAG_ACTIVITY_NO_HISTORY, my activity that is launched is not kept in the activity-stack, meaning when I start from that 'invisible' activity another activity 'for-result' I can never com back in the onActivityResult because it doesn't know where to go... So my activity gets killed and nothing happens. If run my original code without the flag FLAG_ACTIVITY_NO_HISTORY it works perfect...

[android-developers] PendingIntent launched from widget causes onActivityResult to not be called
I have an issue with one of my applications that is using a PendingIntent to launch an activity from a widget... This is the piece of code that does the trick: PendingIntent pendingIntent = PendingIntent.getActivity(ctx, widgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT); views.setOnClickPendingIntent(resId, pendingIntent); Now let me explain you the cases: This is the flow it should do: [Widget] - Click button, launch activity [StartTimeRegistrationActivity] - task needs to be selected so start TaskSelectionActivity for result automatically [TaskSelectionActivity] - Task selected, so the TaskSelectionActivity is finished and coming back in the onActivityResult - Do some automated stuff in this activity - Finish the activity (so finish() and go into onDestroy()) If, from somewhere in my application, I start the activity manually (so without a pending intent) it's started correctly and executes correctly. However if I start it with the PendingIntent with the flag set to PendingIntent.FLAG_UPDATE_CURRENT part of my flow is not executed anymore, specifically the onActivityResult of the StartTimeRegistrationActivity. So this becomes the flow: [Widget] - Click button, launch activity [StartTimeRegistrationActivity] - task needs to be selected so start TaskSelectionActivity for result automatically [TaskSelectionActivity] - Task selected, so the TaskSelectionActivity is finished, but not coming in the onActivityResult but directly to the onDestory() method (not passing the finish() method anywhere) If I change the pending intent to use the flag PendingIntent.FLAG_ONE_SHOT the flow is executed correctly. But then, when the StartTimeRegistrationActivity is open, and the user presses the back-button to cancel his action (a case that is perfectly acceptable for this application) he cannot click the button anymore because the PendingIntent.FLAG_ONE_SHOT declares that it will be automatically cancelled as soon as the send() method is called once on it. So any ideas here how to work around it? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Ant build fails since upgrading SDK to latest revision
I've been looking into this issue some more and still cannot find out how to fix it. But one thing is for sure, the libraries for my app (which are in the 'libs' directory) are not included in the ant-build for testing. Here are two screenshots of a decompile. The first screenshot shows you a decompile of the application that I manually build using my IDE. You can see that it includes my libraries (Roboguice for example) https://lh3.googleusercontent.com/-Lz-4MOMEchs/T36KvVLLkUI/AaA/cxHWXwvIxjs/s1600/decompile_manual_build.png On the second screenshot you can see a decompile of the APK that Ant generated during the test-build: https://lh5.googleusercontent.com/-QeLmmkdDpgA/T36K6CXSTSI/AaM/M5fOIBLq-jU/s1600/decompile_ant_build.png That one does not contain the libraries (no Roboguice for example) that I need for the app, only some testing libraries... But the libraries are in the 'libs' directory so what else can I do to enforce them to be taken into account? Also when I do a release with Ant and I decompile the generated APK file the result is the same in the first screenshot (so included the libraries...!)

Any idea how to work around this? I though that maybe it just took the first few characters (always 3) after the BOM into account but I added some spaces between the BOM (exactly 3) and then it's ok.

[android-developers] Writing files in UTF-8
In my application users can export their data (or a subset of it) to a CSV
file (to be used in Excel or any other spreadsheet app).
However some of my users are reporting that if they export some that
contains non-western characters (like chinese or hebrew writings) the text
is not correctly in the export.
When I try this myself I indeed see that the text is not correct. Here is
the code that writes the content to the file (UTF-8 encoded).
Writer out = null;
try {
out = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(file), UTF-8
));
out.write(result.toString());
} catch (UnsupportedEncodingException e) {
Log.e(LOG_TAG, The encoding is not supported!, e);
} catch (FileNotFoundException e) {
Log.e(LOG_TAG, The file is not found, e);
} catch (IOException e) {
Log.e(LOG_TAG, Exception occurred during export..., e);
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {
Log.e(LOG_TAG, Could not close the writer, e);
}
}
}
Is there anything else that I can do to optimize my code to support those
languages?

[android-developers] Re: Writing files in UTF-8
Why are you using FileOutputStream AND OutputStreamWriter AND BufferedWriter? I need the OutputStreamWriter to specify the encoding, however that doesn't seem to work... What is the type of result? How did you put content in it? The result is a CSV file, I just loop over some DB records and build a string, then I write the string to the writer... You are not checking the returnvalue of your write statement. the Writer.write(..) method does not return anything... it's void...! Please explain exactly what is wrong with it. I thought I did, but anyway, I'll do it again: Very simplistic explained: so in the application text (that the user enters) is stored in a DB, I read the contents of the DB and construct a string. Then I write the string in the writer (to the file)! So when I do so for Dutch, German, English, Frensh,... (all western languages) it works. However users started reporting that when inputting Chinese or Hebrew characters the application works just fine but for the export the content of the CSV file is unreadable. You can open the CSV file in a text-editor or a spreadsheet editor but the characters that should be Chinese or Hebrew are just unreadable characters. So instead of seeing something like this: 這是一個測試 I see something like this: â €å”€å”€å”€à €à €à €ç¼€ç¼€ç¼€ç¼€ç¼€ç¼€ç¼€Ì€Ì€Ì€Ì€Ì€Ì€ So it's a matter of encoding that is not correct.

[android-developers] Fail ant-build on continious integration server
As continious integration server I'm using Jenkins. But when I'm locally on my pc building my Android application, the ant-build fails when one of my unit tests fails. However when I build the app on my continious integration server ant does not fail when one of my tests is failing. Both locally and on the server I'm using the same Android SDK, same emulator configuration to run my tests and same ant targets (all clean emma debug install test). I don't know if this is the right place to be with this question (in other words is it Jenkins releated or is it Android related...) but I hope to find just something here... :) Kr, Dirk -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Problem with writing files to internal memory (not visible on file browser on ICS)
I have a problem when I try to write a file to the device's SD-card.
It's an export in CSV format that I save to the directory /Android/
data/eu.vranckaert.worktime/files/worktime/ and the name of the file
is export.csv in this case.
File exportDir = ctx.getExternalFilesDir(null);
File file = new File(exportDir, export.csv);
//Already had the issues before I was applying these
permissions!
file.setReadable(true, false);
file.setWritable(true, false);
file.setExecutable(false, false);
boolean fileAlreadyExists = file.createNewFile();
if(fileAlreadyExists) {
file.delete();
file.createNewFile();
}
FileWriter fw = new FileWriter(file);
BufferedWriter bw = new BufferedWriter(fw);
bw.write(result.toString());
bw.close();
fw.close();
I tested this code and here are the results:
1) Emulator 2.3 with SD = no problem
2) Emulator 3.2 with SD = no problem
3) Emulator 4.0 with SD = no problem
4) HTC Hero (running 2.3.3) with SD = no problem
5) Samsung Galaxy ACE (running 2.3.x) with SD = no problem
6) Samsung Galaxy Nexus (running 4.0) with the 16 GB build-in SD =
problem!!
The problem I have is that I cannot see the file that is created:
a. when I use a file browser on the device
b. when I connect the device to my windows computer (windows 7)
However I can see the entire directory structure created, just not the
files! I already had this problem before when I was not applying the
permissions, I just thought to try that without any luck.
But I noticed something else, when launching DDMS I can see the file
and download it from the device on my computer.
However this is not user-friendly so I want to have my export working
on ICS as well witouth any hacks for the user to access his exported
files.
I also tried to change the directory where it's saved, instead of the
/Android/data directory structure, I set it up to save on my SD-card
to the /worktime/ directory, but that doesn't work either!
You can check out the DDMS and explorer screenshots I took attached to
the issue on google code: code.google.com/p/worktime/issues/detail?
id=84#c4
Does anyone know what I'm doing wrong or can do better to have this
working?
Kr,
Dirk

[android-developers] Permission Denial: starting Intent when launching my activity from my widget
I'm developing the WorkTime application for Android and I am
expieriencing some strange behaviour with my widget.
SO I have a widget on which basically 3 parts are clickable:
1) The header = opens a selection dialog
2) A button = starts an activity to start a new time registration
3) The rest of the widget = launches the main screen of the
application
Before telling you my exact problem I want to mention to you that I
have tried the application on a Nexus One and two emulators (4.0.3 and
2.3.3).
The issue is only valid for the Nexus One!
So a couple of hours ago I was still using the widget normally, all
buttons were working fine.
I then installed a new version of the application (with some minor
fixus, BUT nothing changed to the widget part or any activity called
from within the widget) And suddenly when I was pressing the
header (1) or the button (2) nothing happend and (when connected to my
PC) in the LogCat I saw some exceptions (attached at the bottom!).
Before the update (so no files related to the widget or the activities
launched from the widget have changed!) everything was working fine.
I also tried uninstalling the application and installing the old
version again (the version that has worked a few hours ago), but still
the two activities could not be launched and the same exceptions are
thrown.
The latest code with which I'm having these issues is availble on
http://code.google.com/p/worktime/source/browse/trunk.
Does anyone has any idea what could have gone wrong? :s
I read somewhere that I could add the android:exported=true
property in the AndroidManifest.xml file for those two activities, but
why does it suddenly fail for those two activities and it still works
for the third...?
Here are the two exceptions:

[android-developers] Re: Using sd-card in 4.0 emulator
I prefer Mac (or even Linux) but my employer enforces me to use Windows so yeah... :-) But here's what I just found (posted it already): Ok I found the problem, the my documents directory is set to be in D:\DVRANCKA . So when the AVD manager creates an AVD it's places under D:\DVRANCKA\.android\avd \...However when I want to launch an AVD it's looked for in the C: \user \DVRANCKA\.android\avd\... Is there somewhere I can configure that for launching he should also look at D:\DVRANCKA?

[android-developers] Re: Slow scrolling in Date/TimePicker using Holo theme
Thanks for the help Matt! I implemented a CustomDatePicker and
CustomTimePicker, for both classes have overriden the
onInterceptTouchEvent method and works like a charm now! :)
On 16 dec, 16:47, Matt H mjholg...@gmail.com wrote:
Hi Dirk,
I had the same problem (noticed it yesterday, too, coincidentally!).
The issue is that the ScrollView is intercepting and stealing the
touch events once your finger moves outside of the Date/Time Picker
controls.
To work around this, I created sub classes of Date/TimePicker which
prevent the parent from stealing events after the initial touch down
(see below). If you use those in your layout XML instead, you should
find the problem goes away.
Hope that is useful!
Matt.

public CustomDatePicker(Context context, AttributeSet attrs)

}
public CustomDatePicker(Context context)

super(context);

/* Prevent parent controls from stealing our events once we've
gotten a touch down */

ViewParent p = getParent();

[android-developers] Slow scrolling in Date/TimePicker using Holo theme
I'm trying to build an activity on which the user can change a certain
date and time.
So I created an activity and a layout file, in the layout file
(containing more than just the date and time picker, you can see it
beneath) i define the date and time picker.
The application android 2.1 compatible, but I compile it under 3.2 so
that I can use the Holo theme in the entire application.
Running the application on 2.1 till 3.1 gives me the old-style date
and time picker, where you can type the value or press plus/minus.
Running on 3.2 or 4.0 gives me the new Holo styles date and time
picker, where you can also type or press plus and minus. So far so
good. But with the new style you can also scroll on the day, month,
year, hour and minute, but for some reason that doesn't quite work in
my application! What it does: I try to scroll down (let's say minute
is on 49, I want to change it to 30). It starts scrolling, and the
first pixels are just fine and smooth. But then it blocks and
everytime i initiate a scroll-swipe again it scrolls only a few
pixels. To scroll from 49 to 48 I have to scroll 5 or 6 times... Not
really normal I guess.
I also use the DatePickerDialog in some cases, there scrolling goes
smooth as supposed to be.
So is there anything I forget to do when using a date and/or time
picker in an activity?
Attachments:
Here is my layout file:
ScrollView xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=fill_parent
android:layout_height=fill_parent
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=fill_parent
android:orientation=vertical
!-- Content... --
DatePicker android:layout_width=fill_parent
android:layout_height=wrap_content/
TimePicker android:layout_width=fill_parent
android:layout_height=wrap_content/
!-- Content... --
/LinearLayout
/ScrollView
And here is the part of my activity where I set the values on the date
and time picker:
datePicker = (DatePicker) findViewById(datePickerId);
timePicker = (TimePicker) findViewById(timePickerId);
datePicker.init(part.get(Calendar.YEAR),
part.get(Calendar.MONTH), part.get(Calendar.DAY_OF_MONTH), null);
if (getAndroidApiVersion() = 13) {
datePicker.setCalendarViewShown(false);
datePicker.setSpinnersShown(true);
}
timePicker.setIs24HourView(true);
timePicker.setCurrentHour(part.get(Calendar.HOUR_OF_DAY));
timePicker.setCurrentMinute(part.get(Calendar.MINUTE));

[android-developers] Transparent background issue with image in 2.2, not 2.3
All, For my current project I'm having an issue with images that I have never seen before on Android. I have an image (link at bottom) that I use in my application and as you can see in the screenshot (screenshot of HTC Hero, running 2.2, at the bottom) and the background is a little gray while the png has a transparent background... However when testing this on my N1 device, running 2.3, the background is transparant (screenshot of N1 at the bottom), as should be... Does anyone has an idea what causes the issue, I also have the issue on a 2.2 emulator, not on the 2.3 emulator, and how I could solve it?

[android-developers] ListView items appear 2 or 3 times
Hi all,
I'm having an issue with the ListView in Android.
So I have an activity extending the ListActivity, in the activity I
have an innerclass for my adapater.
Now both on my device and the emulator some entries appear 2 or 3
times in the list (not always the same items) although the size of my
ListLabel is always the same!
On the emulator I noticed that it's mostly related to the scrolling in
the list... If I scroll down some entries are duplicate, if I scroll
up and down again the entries have changed all over the list...
Is there anything in my code that you guys can see that is wrong?
Here's my code:
this.labels = labelService.findAll();
Collections.sort(this.labels, new LabelByNameComparator());
Log.d(LOG_TAG, labels.size() + labels loaded!);
ManageLabelsListAdapter adapter = new
ManageLabelsListAdapter(labels);
adapter.notifyDataSetChanged();
setListAdapter(adapter);
/**
* The list adapater private inner-class used to display the
manage labels list.

private class ManageLabelsListAdapter extends ArrayAdapterLabel
{
private final String LOG_TAG =
ManageLabelsListAdapter.class.getSimpleName();
/**

*/
public ManageLabelsListAdapter(ListLabel labels) {
super(ManageLabelsActivity.this,
R.layout.list_item_labels, labels);
Log.d(LOG_TAG, Creating the manage labels list
adapater);
}
@Override

parent) {

Dirk,
You have a bug in your getView() method.
When a list item layout gets recycled (convertView != null), your code
correctly avoids re-inflating a new layout. However, since the item
layout is being recycled, it's also necessary to update its views with
values for the current item.
Pseudo-code:
getView() {
if (convertView == null) {
inflate a view
}
/* Always execute below code, for both new and recycled item layouts */
YourDataItem item = get data item specified by position
TextView view1.setText(item.name);

And if it is, could you guys give me some tips before I start on this? Kind regards, Dirk -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Google Maps: Let the user choose a location
Hey all, I've been working on an application lately that is using GMaps to display a location that is stored in the devices database. However when no location is available (no GPS signal is available) the user can go through an edit wizard and at a certain point he can add a location himself. I already have to code to display the stored location, but is it possible to write something so the user get's to see a map and when he clicks/touches on a certain area a map pointer appears and the location is stored. Is that possible in any way? Is there any good online documentation available? I searched through this group and on Google but couldn't find anything usefull.

[android-developers] Trying to create wizard-like layout
Hey, I'm currently trying to create some wizard-like layout for some edit/ add views in my Android application. Therefore I use only one activity and different layout files which I load. Altough there is something wrong with my layout files. The layout files can be found here: http://pastebin.com/YmW2PmLw What I'm trying to do: So I have my screen in which some date and time can be set manually with the date and time pickers. At the bottom of the screen I want a bar with a cancel button and next button (I'm not sure yet if I will keep this cancel button as the device's back button does the same, but whatever). With the layout file posted this works. So my problem: When switching the device from portrait mode to landscape my time picker get behind the button bar at the bottom, as I added a scrollView I can scroll to the time picker but a part of the the time picker stays invisible behind the button bar. Does any of you think of a solution for that? So I want to scroll but the scrolling area should come just above the button bar and not underneath! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Can an AppWidget's RemoteViews be edited/created dynamically, or only from XML?
James, To modify the widget layout from an activity or service you should use some could like this: RemoteViews rv = new RemoteViews(context.getPackageName(), WIDGET); rv.setTextViewText(R.id.label1, text for label1); rv.setTextViewText(R.id.label2, text for label2); rv.setTextViewText(R.id.label3, text for label3); ComponentName cn = new ComponentName(context, YourActivity.class); AppWidgetManager mgr = AppWidgetManager.getInstance(context); mgr.updateAppWidget(cn, rv); As you can see in the example (written on the fly so not sure that it is 100% correct) you can edit multiple view-object in just one RemoteViews object. Don't start using different RemoteViews for each object on the view you want to edit cause you will run into problems with the updating right then. Also, have a look at the RemoteViews class to see what you can exactly do with it, don't know if you can make things visible or invisible with it. Although whatever that you want to edit with the RemoteViews should already being declared in the layout.xml file of your widget if I'm not wrong! Kostya, as far as I know that is not possible. You should then just create different widgets with the XML configuration file and perhaps you can reuse the widget provider class you have to implement so that you can share the logic for both widgets (if the content of both widgets is the same off cours.) On 29 mei, 10:42, Kostya Vasilyev kmans...@gmail.com wrote: James, I don't have the answer, but I would like to amend your question. Switching views is one thing, but what if there are versions of the same widget that have different sizes? Minimal widget size is specified in res/widget.xml, using appwidget-provider minWidth minHeight. Is it posible to specify different sizes depending on what widget version the users selects in my configuration activity (or some other way)?

Is there a way to do it with stock Android firmware? -- Kostya 2010/5/28 James W jpbwebs...@gmail.com I suspect the answer is no, but it only seems possible at the moment to update an AppWidget via a RemoteViews object which is inflated from a static XML file. Is there any way to build a RemoteViews object on the fly, or edit the layout of one that is already there? The requirement is that I dont know until runtime exactly how many ImageViews I want to display in my AppWidget. Currently I am setting all the ImageViews I may need in the layout XML file as invisible and then just making the ones I want visible, but am I then limited to what I have in the XML file to start with. It would be far more convenient to be able to just add the ones I need on the fly, and set their properties when updating. Anyone know if there is a way to do that?

Yeah I think it must be something like that if I understand you right.

Now everytime I update the widget I will update both the texts and the intents on the buttons and at first sight, it seems to work just fine right now :) Thanks for the help!

Does this happen with your widget also? Slight difference with my widget is that it was sending intents to itself. Anyway, solution was to set pending intents to widget buttons every time that onReceive is called (since I am sending intents back to widget). After that, there was no more problems with orientation change - buttons were reacting every time. Maybe you can do something similar?

Dirk,
This is the reason your widget sometimes stops responding to clicking.
Each and every RemoteViews update needs to specify complete state,
including data and PendingIntents (if any). The home screen process can
be bumped out of memory, and Android uses the most recent RemoteViews to
recreate widgets. If it's incomplete and only contains text updates,
then pending intents will be lost.
Same thing happens on orientation changes - there is no onUpdate(), just
the mechanism described above.

I think String is right about that. I wouldn't do that either just to
save battery life!
However I think it is better to set the update interval of the applet
to a high enough amount of time (like 24 hours or sth) and just update
the widget manually. I'm currently working on a widget to and in my
case the widget only receives an update upon clicking a certain
button.
The way I do that is like this:
RemoteViews rv = new RemoteViews(context.getPackageName(), WIDGET);
rv.setTextViewText(R.id.textField, Updated value for some text on the
widget);
ComponentName cn = new ComponentName(context, YourActivity.class);
AppWidgetManager mgr = AppWidgetManager.getInstance(context);
mgr.updateAppWidget(cn, rv);
That should basically work to update a widget.
Oh and one tip: using the this method you should do all updating just
after the line rv.setTextViewText(...). If you execute this entire
block a few times after each other you can get into troubles when
updating the widget.

[android-developers] Stalling widget buttons after some time
Hey all, I'm currently working on a widget/application and I have an issue with that. Before I get into the issue you could check out the code which is available just over here: http://code.google.com/p/workregistrationwidget-android/source/browse/ So my issue... :) The widget contains two buttons. The linking of the buttons with an activity happens in my widget provider (http://code.google.com/p/ workregistrationwidget-android/source/browse/trunk/ WorkRegistrationWidgetAndroid/src/eu/vranckaert/workRegistrationWidget/ widgetProvider/WorkRegistrationWidgetProvider.java). So far so good. Clicking the buttons interacts with my activities and my widget gets updated. However after some time (and this did not happen with myself but with one of my testers) the buttons just didn't work anymore. He had to remove the widget from and add it again (no re-install) and it fixed the problem. So I was thinking about two possible places where it might go wrong: 1) First off all I was thinking that the linking with the buttons to an activity through an intent maybe isn't the right way. Anyone who knows? 2) And secondly because there is always large period between when it was working and when it wasn't anymore (a few hours at least) I was wondering if it could have anything to do with the updatePeriod set in the widget info xml file (http://code.google.com/p/ workregistrationwidget-android/source/browse/trunk/ WorkRegistrationWidgetAndroid/res/xml/ work_registration_widget_info.xml) altough it is set to 24 hours. I should mention that I tested it on Android 1.5, 1.6 (only for a small amount time in the emulator), 2.1 and 2.2 and I can't reproduce the issue he's having.

[android-developers] Starting activity witouth window from widget
I recently (yesterday in fact :)) started creating widgets. So my
first widget I want to create is something like:
* A 2x2 widget
* Containing 2 buttons
* Button 1: Register current time and location
* Button 2: Open up an activity where configuration can be
modified, registered times and location can be viewed,...
Now the problem for me is button 1. As I only try to do some
registration data (so no further user input required after pressing
the button) I would like to just show a loading bar and after wards
Toast a message to screen, or a popup if anything goes wrong.
This is what I do now:
* In my widgetProvider
Intent intent = new Intent(context, LogDataActivity.class);
PendingIntent pintent = PendingIntent.getActivity(context, 0, intent,
0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.my_widget_view);
views.setOnClickPendingIntent(R.id.startButton, pintent);
* In my LogDataActivity class
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Do some of my stuff
Toast.makeText(LogDataActivity.this, Success,
Toast.LENGTH_LONG).show();
super.finish();
}
So what happens: I click the button, a plain black screen pops up
(Altough I did not specify a layout upon creating the activity), and
after my work is done the Toast shows up and the activity gets

[android-developers] Re: Starting activity witouth window from widget
Sorry all for bothering.
I didn't look well enough in this group, now I found the answer:
http://groups.google.com/group/android-developers/browse_thread/thread/8ac30e3b1870fb98/1cc71bab92a7ff97?lnk=gstq=Starting+activity+without+layout#1cc71bab92a7ff97

I recently (yesterday in fact :)) started creating widgets. So my
first widget I want to create is something like:
* A 2x2 widget
* Containing 2 buttons
* Button 1: Register current time and location
* Button 2: Open up an activity where configuration can be
modified, registered times and location can be viewed,...
Now the problem for me is button 1. As I only try to do some
registration data (so no further user input required after pressing
the button) I would like to just show a loading bar and after wards
Toast a message to screen, or a popup if anything goes wrong.
This is what I do now:
* In my widgetProvider
Intent intent = new Intent(context, LogDataActivity.class);
PendingIntent pintent = PendingIntent.getActivity(context, 0, intent,
0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.my_widget_view);
views.setOnClickPendingIntent(R.id.startButton, pintent);
* In my LogDataActivity class
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Do some of my stuff
Toast.makeText(LogDataActivity.this, Success,
Toast.LENGTH_LONG).show();
super.finish();
}
So what happens: I click the button, a plain black screen pops up
(Altough I did not specify a layout upon creating the activity), and
after my work is done the Toast shows up and the activity gets
'killed'.
Basically that is what I want to do except for the black screen to
show up. Is it possible not to show a screen upon creating the
activity?

[android-developers] Custom Dialog
I'm trying to create a custom dialog in my application to show an

[android-developers] Creating dialogs from a thread
I'm working on an application which loads some data from the net in a
thread.
However when something goes wrong (no internet connection or sth) I'dd
like to create a dialog to show an error message to the user.
However my code works fine not using threads but creating a dialog
from my thread makes my application crashing.
In my activity I have overwritten the onCreateDialog method and looks
like this:
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog = null;
switch (id) {
case EPISODE_LOADING_DIALOG:
ProgressDialog progressDialog = new
ProgressDialog(this);
progressDialog.setMessage(this.getString
(R.string.progressLoadingTitle));
//progressDialog.setTitle(R.string.progressLoadingTitle);
dialog = progressDialog;
break;
case EXCEPTION_DIALOG:
if (exceptionMessageResId == null) {
exceptionMessageResId =
R.string.defaultExceptionMessage;
}
AlertDialog.Builder builder = new
AlertDialog.Builder(this);
builder.setTitle(R.string.exceptionDialogTitle)
.setMessage(exceptionMessageResId)
.setCancelable(false)
.setPositiveButton(R.string.dialogOK, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface
dialog, int id) {
dialog.cancel();
}
});
exceptionMessageResId = null;
default:
dialog = super.onCreateDialog(id);
}
return dialog;
}
The method which is calling a method and catching an exception (within
a thread):
private void getEpisodes() {
try {
episodes = myEpisodesService.retrieveEpisodes(user);
} catch (InternetConnectivityException e) {
String message = Could not connect to host;
Log.e(LOG_TAG, message, e);
exceptionMessageResId =
R.string.internetConnectionFailureReload;
showDialog(EXCEPTION_DIALOG);
}
runOnUiThread(returnEpisodes);
}
So does anyone of you guys knows what I am doing wrong here? Can't you
create a dialog from within a thread?
If so, what's the best way of handling my exceptions here?

[android-developers] Re: Creating dialogs from a thread
It seems your solution does not work either. As long as I'm doing it in a thread it doesn't work. Altough what I tried next was setting the error message for the user in my catch clause. And right after the thread finished I handled the showing of the errors based on wheater some error message was set or not! Thx for your help!

The way I tried it was with a custom written ArrayAdapter but I then get some rendering issues, for example no data is shown and when I start to scroll the data is filled in in some rows but the not the data belonging it that row and that kind of stuf.

[android-developers] Re: ListView
Here is an excerpt from one of my books that discusses the process: http://commonsware.com/Android/excerpt.pdf I tried the examples coming with the SDK in combination with some more advanced stuff I found online but didn't work. I now had a look at Mark's PDF and modified some things and found my main/biggest problem: This is how I retrieved the TextView element of each row: TextView topText = (TextView) findViewById(R.id.episodeRowTitle); And this is what it should be (watch the 'row.'): TextView topText = (TextView) row.findViewById(R.id.episodeRowTitle); So I guess beceause I forgot the 'row.' I go my first created row and had it overwritten all the time. Is that correct? ViewHolders that give you better performance but are harder to grasp. Christine, I will certainly give this a test now I got my ListView working! Thx a lot all!! -- You received this message because you are subscribed to the Google Groups Android Developers group.
