[Q] Widget Issues - Android Software Development

Hi,
I am trying to create my first Android App, a widget to turn the Master Sync function on and off, and for some reason the widget is not clickable on the home screen.
Code Below, can anyone help please?
public class MasterSync extends AppWidgetProvider {
/** Called when the activity is first created. */
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// now label the property of the button
boolean sync = ContentResolver.getMasterSyncAutomatically();
if (sync){
ContentResolver.setMasterSyncAutomatically(false);}
else
//
if (!sync){
ContentResolver.setMasterSyncAutomatically(true);
}
}}

[Q] AlertDialog (-> list with a lot of elements) how to handle orientation-change

Hi,
A few weeks ago I started developing an Android app but I've gut one problem
If the user changed the orientation of his phone the Activity is of course newly created. If there is ProgressDialog opened, I simply open a new one and the user does not realize it, but if I show an AlertDialog containing a few hundred elements and the user scrolls a bit he/she will realize it after I recreate the AlertDialog because the dialog will start again with the first element and the user has to scroll newly to the element he wants.
How I handle the "ListDialog":
At first I have two classes which simplify the ListDialog because I use it a few times...
ListDialog class:
Code:
public class ListDialog {
public static int CHOOSE_MODE_ONLINE = 0x01;
public static int CHOOSE_MODE_BOOKMARK = 0x02;
public static int CHOOSE_MODE_LOCAL = 0x03;
public static int CHOOSE_CHAPTER_ONLINE_DOWNLOAD = 0x04;
public static int CHOOSE_CHAPTER_BOOKMARK_DOWNLOAD = 0x05;
public static int CHOOSE_CHAPTER_ONLINE_READ = 0x06;
public static int CHOOSE_CHAPTER_BOOKMARK_READ = 0x07;
public static int CHOOSE_CHAPTER_LOCAL_READ = 0x08;
public static int CHOOSE_CHAPTER_LOCAL_DELETE = 0x09;
public static int GOTO_PAGE = 0x0A;
public static void show(Context context, String title, CharSequence[] elems, final ListMethodInvoker invoker)
{
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setItems(elems, new DialogInterface.OnClickListener() {
%mail%Override
public void onClick(DialogInterface dialog, int which) {
invoker.invoke(which);
}
});
builder.setOnCancelListener(new OnCancelListener() {
%mail%Override
public void onCancel(DialogInterface dialog) {
invoker.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
ListMethodInvoker class:
Code:
public class ListMethodInvoker {
public void invoke(int id)
{
}
public void cancel()
{
}
}
and now I create the dialog:
Code:
ApplicationController.get().addOpenedDialog(ListDialog.CHOOSE_MODE_ONLINE);
ListDialog.show(OnlineActivity.this,
mangaController.getManga().getMangaName(),
new CharSequence[]{"Add to Bookmarks", "Download a Chapter", "Read a Chapter"},
new ListMethodInvoker()
{
%mail%Override
public void invoke(int id)
{
ApplicationController.get().removeOpenedDialog(ListDialog.CHOOSE_MODE_ONLINE);
switch(id)
{
case 0: addBookmark(mangaController.getManga()); break;
case 1:
ApplicationController.get().addOpenedDialog(ListDialog.CHOOSE_CHAPTER_ONLINE_DOWNLOAD);
handleChapter(ChapterMode.Download);
break;
case 2:
ApplicationController.get().addOpenedDialog(ListDialog.CHOOSE_CHAPTER_ONLINE_READ);
handleChapter(ChapterMode.Read);
break;
}
}
%mail%Override
public void cancel()
{
ApplicationController.get().removeOpenedDialog(ListDialog.CHOOSE_MODE_ONLINE);
}
});
I also add the ID of the dialog to my ApplicationController which allows me to remember if a dialog has been openend and I can recreate it when onCreate(...) is called again.
(The ApplicationController uses the singleton design pattern which always allows me to retrieve the same instance of the ApplicationController.)
Thanks in advance
best regards
mike
btw: If you wonder why I write %mail% instead of the correct symbol, I get the following exception message if I use it: To prevent spam to the forums, new users are not permitted to post outside links in their messages.

[Q] Handling ACTION_SCREEN in a widget

Hi,
I'm doing a widget that needs to be update on screen_on or on
user_present. As I'm not hable to register a BroadcastReceiver inside
the widget I'm doing it in a Service that is triggered by the widget
like this:
Widget.java:
Code:
@Override
public void onEnabled(Context context) {
super.onEnabled(context);
context.startService(new Intent(context,
WidgetService.class).setAction(WidgetService.ACTION_WIDGET_START));
}
WidgetService.java:
Code:
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
String action = intent.getAction();
Log.d(LOG_APP,"WidgetService onStart: "+action);
if (ACTION_WIDGET_STOP.equals(action)) {
this.unregisterReceiver(mReceiver);
stopSelf();
return;
} else if (ACTION_WIDGET_START.equals(action)) {
// register receiver that handles screen on and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
this.registerReceiver(mReceiver, filter);
return;
}
The problem is that when I try to register the receiver I get the
error that the service has leaked IntentReceiver because it was
already registered. Ive checked and no duplicate registration was done
in my code.
Do you have any idea what I'm overlooking?
Thanks,
PMD

[Q][SOLVED] PreferenceActivity as AppWidget Config

I have been using a hand built ListActivity as my AppWidget config Activity but to be honest it looks ****ty and doesnt fit in with the rest of the app. So i wanted to transition over to a PreferenceActivity. i made a stub of a PreferenceActivity that launches the layout just fine when it is the main activity. but when i try to change from my ListActivity to my PreferenceAcitivity i get no launching of PreferenceActivity when i launch my widget. all i get is my widget.
i did a refactoring of my xml files to change the instances of my ListActivity (GITextConfig) to my PreferenceActivity (GITextPreferences).
how can i use a PreferenceActivity as my config?
do i need to have a dummy Activity be the config with a button to launch the PreferenceActivity? cause that works just fine. its lame and shouldnt be that way... nvm that does not work... i just cant get a prefs activity to run from an appwidget
anyone? this is quite annoying... i know it can be done as other widgets like gmail unread count does this. at least it appears to have a preferenceactivity as the configuration
got it to work. i dont know what i was doing before but i think i had a little too much of a stub for it to work. after i implemented the appwidget id verification and created my PreferenceManger and overode the onBackPressed() method it seems to work.... happy and confused.
Code:
public class GITextPreferences extends PreferenceActivity {
private int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PreferenceManager localPrefs = getPreferenceManager();
localPrefs.setSharedPreferencesName("GITC_Prefs");
addPreferencesFromResource(R.xml.gitc_preferences);
// Find the widget id from the intent.
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
// If they gave us an intent without the widget id, just bail.
if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
finish();
}
}
@Override
public void onBackPressed() {
// Make sure we pass back the original appWidgetId
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
}

[Q] Dialog out of Activity

Hello app developers!
I have got serious problem. Every time I call alertdialogs or other dialogs I see them only in activity. But my app needs to show this dialog when user works on phone, that's why it must be shown out of activity. Any ideas?

You cannot do this. There is simply no feature for that. I have had that problem, too.
Use a Notification or a Toast message.
There is a work-around for this. If you run a service, you can technically launch an activity that can resemble this.
I have an app that uses a broadcast receiver to listen for the events I want to alert my user to. I created a custom layout for my alert dialog and then when the event happens, my broadcast receiver calls the activity.

Yes, great idea. Launch a transparent Activity and start a dialog. Set an onDismissListener and close the app when the dialog is closed.

If I start a transparent activity user can't see that it was started as I understand. Can you give code for broadcast receiver maybe I misunderstand something
The broadcast receiver is just the mechanism I use to launch the activity. It is a mere intent that I start from it. Below is the class I use for my alertdialog. You won't be able to cut and paste because I also created my own class to dismiss the activity.

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
showAlert();

// it seems that LinearLayout doesn't trigger a MotionEvent.ACTION_UP or MotionEvent.ACTION_MOVE
if (actionPerformed == MotionEvent.ACTION_DOWN)

I understood everything except the way how app switch between position before signal came and required activity with alert dialog in it. As I see this code initialize activity and alert dialog but don't contain switching that I need
Are you asking how I call the dialog? If so, a simple intent from a broadcast receiver.
Code:
Intent i = new Intent(context, SilentDialog.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
I would use the AlertDialog.Builder class for compatibility.
Why not use a notification, I think that is more elegant.
Code:
public class InstalledReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager ;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
if (BaseActivity.DEBUG) System.out.println("Received Broadcast");
Boolean update = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
mNotificationManager = (NotificationManager) context.getSystemService("notification");
SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean disabledNotifications = getPrefs.getBoolean("disableNotifications", false);
if (!disabledNotifications && !update) makeNotification(context);
}
private void makeNotification(Context context) {
CharSequence label = context.getString(R.string.labelNotify);
CharSequence text = context.getString(R.string.textNotify);
CharSequence full = context.getString(R.string.fullNotify);
final Notification notification = new Notification(R.drawable.ic_launcher,text,System.currentTimeMillis());
notification.setLatestEventInfo(context,label,full,null);
notification.defaults = Notification.DEFAULT_ALL;
mNotificationManager.notify( 0, notification);
}
}

I agree, but if he wants to use a dialog, we help him to make one.
The bad thing about the dialog is that it will interrupt whatever the user is doing. This could be very annoying. And who wants to use an app which has annoying popups?

When I use this code activity don't shows when I am out of application. For example Handcent SMS when SMS comes to user shows up a great dialog over all windows. My aim is the same thing

Ah. You need to call setContentView. Create a transparent View and pass it as a parameter.

Doesn't help:

finish();
}
});
// Set the Icon for the Dialog

}
If you use another layout, is the Activity opened?
Is the "Here" written to the log? Is there any Error message?
And I recommend configuring the AlertDialog within the AlertDialog.Builder: http://www.mkyong.com/android/android-alert-dialog-example/
(However, I guess that it will not solve your problem.)

Read This guide first, then it's easier to help you.
What I'm seeing is that you should set your message=getIntent ().... ; in the onCreate since the Intent data is probably not available before.
