[Q] activity properties - Android Q&A, Help & Troubleshooting

Hi every one
I have already develop a new android app, this app have three activities:
the first one :
there is just one button when the user press the button it will transfer him to the second activity and this is the default activity
the second one:
there is multiple edit Texts and spinner item and two buttons the user fill the data and when he press the save button it will save the data in a shared preference and transfer him to the third activity
the third one:
it is a list activity and it will list the shared preference that the user saved
so if there is a shared preference I have change the default activity to the third activity, if not it will stay the first activity
how I can do that ????
and thanks for helping...:good:

Release rk-Location Switch (1.0.3) [Updated 15 April 2008]

Here is a 'Phone location based application trigger’. Launches other applications, command lines and MortScripts and anything based on time frame and location you setup. Works on Windows Mobile Professional 5/6 (PDA with Phone) only.
Some of the possible uses have been added at second post below.
This is more advanced version of my application rk-Sleep, where you could just perform one action at one location.
rk-LocSwitch can have any numbers of locations and any numbers of actions. But please do understand that this is not a 'readymade profile application' but by configuring it properly you could make it a profile application and much more. Ultimately you can automatically customize your phone based on where you are and the time span you setup.
Also support fixed actions, actions at pre-defined time, not based on the location (This is helpfull to set up backlight 'Bright' during day hrs and 'dim' during eventing/nights)(This feature is freeware and does not expire)
Now the important thing, this is not a freeware, it is 3.99 USD for XDA-Developers.com members. The trial version runs for 15 days so that you can test it and see if it satisfies you.
Update 1.0.6
Support for undefined/unknown location actions added.
Application now by default starts in minimized mode(not the sys tray mode)
Update 1.0.5
Error while 'Testing' the actions is rectified.
Update 1.0.4
Option to Show/Hide the Tray icon added
Debug support added.
Cosmetic changes done.
Update 1.0.3
Support for hide/show 'Un-Defined' location icon.
Bug fixes
Update 1.0.2
Support command line tags, eg Application could automatically send information such as LocationName, LAC, CellID by using the command line tags <LocationName>, <LAC>, <CellID. By this you could even send sms based on your location Entry/Exit along with location info.
Application can update registry with the current Location name, LAC and CellID.(HKCU\Software\rk-LocSwitch). Now your custom application can access the location information!
New menu added to copy TowerIds from one location to other.
New menu added to copy actions from one location to other.
New menu to force saving of the configuration data.
Bug fixes
Setup:
Install the application.
Run the application rk-LocSwitch from programs for the first time from the programs menu, after which the application starts automatically after soft resets.
A new task bar icon will appear in the task tray, click it to launch the application(application runs hidden, this is the only way you can access the UI to set it up)
First tab in the application is ‘General’, the information mostly read-only; you can specify the polling time (in minutes) and enable/disable the application.
‘Locations’: lot of information here. First you create a new location from the top part of the screen.
Location name is just a name such as ‘My Home’, ‘Office’ etc
Choose a icon ‘which would be displayed on the top notification bar’(you can have custom icons, just add the icons to the ‘\Icons’ folder under \Programs\rk-LocSwitch)
Check the box ‘Notify’(when ever you are at known location, a icon would show up on the title bar)
Specify the time frame such as 08:00 to 18:00(day schedule) or 22:00 to 06:00(for night schedule)
Specify if the location is of 'Undifined Type', If undefined then time frame settings are ignored and LocationIds are removed automatically.
Click OK to save this location
Add the current tower id displayed to the list, you could have multiple towers (if the location has interference from multiple towers or if you have say multiple ‘Places’ put under same location. Such as you want to configure the location ‘Office’ at two different physical locations but you want to have similar actions to perform.)
Now go to the ‘Actions’ button
You have ‘Entry’ and ‘Exit’ actions. You can add multiple actions for each action type. You can even order then ‘up’ or ‘down’. Use the ‘Action’ menu for additional commands such as ‘test the action’.
Next tab is 'Fixed Actions' here you could setup actions independent of 'Location' meaning these actions takes place irrespective of 'Locations' Useful for setting the backlight of the device.
Next tab is log where each attempt based on the polling time is logged. You can change the log action to log all, location change (Actions) only or none. Once you understand the concept put it to ‘None’(but if you think that something is not working then switch the log to all and investigate)
Last tab about: which is basically the registration module and the version info
Important notes:
Notes: if you want to configure home day and home night, you must have two locations setup such as ‘Home Day’ and ‘Home Sleep’ have the time frames carefully set e.g. 08:00 to 22:00(Home Day) and or 22:00 to 06:00(for night schedule). Do not overlap the time frames!
Keep the polling time as large as possible, unless you need real time response.(although I found keeping the polling to minimum (=2 minutes) did not make any noticeable difference to battery usage!. But test it out.
Do not forget to configure the ‘Entry’ and ‘Exit’ actions properly. Enter and exit actions generally should be cancelling each other (i.e. if you switch on flight mode on entry, make sure you have flight mode off on exit)
System is real time( ± Polling Time) , so if you are at home with flight mode activated and if you leave the home at mid night phone would switch back on.
If you really want to exit the program, use the right menu ‘Options’ and choose ‘Save & Exit’
When you start the application(not while activating the rk-LocSwitch) make sure the phone is not in flight mode
More importantly this is a ‘Switcher’ so I do not supply any command line applications to do your custom tasks; they are available in this site and over the internet. You are welcome to link in this thread so that it can be easily accessed by other users. But if some customization what you want is not available then you can make a request, and I will do my best to find one or built it myself.
Check in this thread for more pluggins
Note: This application requires Compact Framework 2.0
You need compact framework 2.0 installed inorder to run this application. The compact framework is already part of WM6, so if your device is WM6 skip this step. But most of the WM5 devices do not have this update. So you must download here and run the installation on your desktop (then active sync to update your device). Only after completing this step install the application.
Thank you all for the support.

rk-LocSwitch Update 1.0.1
Fixes and enhancements
Added support for fixed actions
You can add any number of fixed schedules and add any number of actions on each such schedule(e.g. to set the backlight low during night and bright at day)
These fixed schedules not specific to the locations and will occur at the time specified.
Does work even if the application expired!(it is a freeware, only location service would not work)
Better file browser added, now you do not have to key in the command line.
Bug with the system not clearing some of the old notifications fixed.
Battery use better that before (almost makes no difference on the battery use!)
If you are upgrading from the old version please uninstall the old version and delete any existing notification manually (delete any notification with name ‘rk-LocSwitch’). Then install the new version.
Also added new component rk-BackLight to support setting backlight on command line.
rk-Calendar-Update: Convert all day Calendar events to time spanned events
To convert all day Calendar events to time spanned events automatically so that you don’t get reminders at midnight!
Use this utility if you are entering many appointments during day as 'Full Day Events' and difficult to manage it. Otherwise you can just run this utility once manually.
Read more about it here
Code:
\Program Files\rk-Calendar-Update.exe “08:00” “22:00”
Updates all your 'full day events' to fixed time event with specified time span.
Hmm, No one has any comments?
I really like the idea. Unfortunately, this does not work on CDMA.

Wasn't there a topic about this app with many comments like adding vibration on/off? I'll try this app with hermes.
EDIT: Oh this is a new app (update of rk-sleep)
Guys, can this software send an sms to a predefined no. whenever the Tower ID changes.

It can not send sms as it is now, if you find exe, or mortscript which could send an sms then you could use this program.
This program is like a trigger which calls other executables based on location, so as long as you can point to right executable then you are good.
But let me know if you are not able to find a executable to send sms, I might be able to build one for you.
Hi TyTnGuy,
is it possible to get the geographic Coordinatas wich assigend to the Tower ID somewhere in the www?

What kind of battery indicator app do you use?
Is it a standalone battery indicator? or part of other app?
Really nice.
Im looking from a very long time for an app. which can send an sms to a predefined no. But I couldn't find any such. I would be grateful if you can develop such app.
Thanx.
Looks realy good. Will test this on the HTC Trinity.
Keep up the good work!

[Q] How to organise different screens? Activity or layout?

I'm designing an App with several layers of menus (on the screen, not from the menu button) which lead to several content pages each, so in total I'll be looking at probably 6 screens of Menu and about 30 content screens (just a picture, text and some buttons).
Should this be just 1 activity for the entire application and with each menu and content page loading a different layout xml? If so how do I do change the layout?
Or should each menu screen and content screen be its own activity as well as having it's own layout xml?
Thanks very much for any help.
I usually use dialog box for simple user infos and I prefer activities to do something more complicated, but it's my opinion. I prefer activities because are simplier than using different dialog boxes or anything else, and so my code doesn't become an incredible mess
I don't think it would work to have dialog boxes to display buttons, like I need for my menus or content pages.
If I did only use 1 activity for it, what's the best way to redraw the layout from a different xml when you click a button? Just have the onClickListener call setContentView(R.layout.new_layout)?

Ok, I understand your needs. Unfortunately I didn't use a new layout in the same activity after a button click, it should be tested.
For my game, I have on the same screen different buttons, textviews, and imageviews that appears and disappears, even after a button click. I putted all of them in the same layout xml (one above the other, what a mess!) and I set the different visibility suitably the buttons clicks (the OnClickListener). It works for me because I have 7-8 items to manage, but maybe not so smart for a lot of different items.
In general, Google recommends using different activities, I remember reading about it in the Dev Guide somewhere.
Although maybe your case is different.
The default recommendation of Google is to use activities. But it does depend on your usage - if everything you are doing is related to the same "activity" (for want of a better word), it may make good sense to keep everything in the same class.
You should also think about what behavior you would like the app to have. Do you want the user to be able to use the "BACK" button to step backwards in your menus? If so, it may make sense to implement this as multiple activities (which will give you this behavior for free), rather than implementing it manually.
I think I'm leaning towards activities as from all I've read it does seem to be best programming practice, it just seems a bit of a waste for me to have 1 activity just displaying a menu! However yes, it would be much easier to use activities then just have user press BACK to navigate backwards.
Also with having 1 activity just switching layout it would mean a massive onClick() 'switch' with at least 30 'cases'! I had thought about implementing my own Back button on the screen but that would be a pain to code.
Thanks for the replies, think I'll go with separate activities and see if it works ok, like I said my main concern was that it's a waste of an activity to have it do something so basic!
Maybe ViewFlipper will be useful?
ViewFlipper just seems to add an animation to changing the layout, no? I'm wondering whether I should just change the layout per screen or to start a new activity per screen.
I've worked it out and I've got 27 Menus, each of these is a ListActivity and 62 Content Pages (each of these is an activity calling a RelativeLayout and some onClick Listeners).
In total this is 89 activities, is this too many for one application? I like the idea of having a different activity per page as that means the user can just press the Back button on their phone to go back up the menus rather than coding in one myself. I've got it working with all the menus but only 1 content page and it's ok, but I can imagine that if I add the remaining 62 contents it may get bogged down?
But yeah, is this too many activities for one app? It is likely at a given time the user probably won't use more than 10 of them.
trying to have a single Activity and then have it able to handle every layout you throw at it and its coorosponding functionality will be a nightmare. use multiple Activities. it will also make using the back button alot easier.

Thanks, shouldn't take me too long to create all the content (with copy paste and find/replace) so will see how it works like that.

How to create shortcuts within apps?

Hello,
I've been using Nova Launcher and Button Mapper for years and it comes with one handy feature which is Activity launcher. I am able to create shortcuts to any hidden app/settings and sometimes I can even make shortcut within app depending on which activities that app has.
Does anyone knows is it possible to create custom shortcut activities on Android 9 and Android TV 9?
Let's make few examples if you don't understand what I mean: Shortcut that directly opens YouTube subscriptions/watch later, Shortcut that directly opens HBO GO favorites, Shortcut that directly opens "Downloads" in any file manager etc.
Some apps already have those activities and it's pretty cool to make shortcuts with them on my Android TV Box remote control, while some apps don't have those activities at all except main one.
There is one more example, I use one app called EON TV and in order to go to "Favorites" I need to click over 8 times through UI to see Favorites list. Can I just somehow make custom activity that leads to favorites and map it with Button Mapper on my remote?
Thanks!
