Android :: Shared Preference Listener Being Called Multiple Times When I Change A Pref

May 31, 2010

I've written an app with 3 tabs. Each tab has the same list view with different data sources. I have setup SharedPreferences in the tabhost activity, but I put my onSharedPreferenceChangeListener method in my listactivity. When I change a preference, my listener gets called and it updates my database. This is all working. However, if I change the data in tab 1, it calls my listener once. If I change the data for tab 2 it calls it twice and if I change the data in tab 3 it calls it three times. Any idea why it works this way? I guess I could setup my shared prefs in my listactivity and that might avoid the issue, but I'm curious why my listener is called multiple times if it's in a different tab.

I am using a PreferenceActivity to show some settings for my application.I am inflating the settings via a xml file so that my onCreate (and complete class methods).These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity.

Android :: Explanation Of ADT Layout Editor UI?

Apr 13, 2009

Is there an explanation of the ADT layout editor UI some place? I can't find anything on the Android web site about it. When I look at a layout in the design view, there are a number of fields at the top with labels like MCC, MNC, Lang, etc. I've noticed that I can change the contents of these fields, such as orientation, and it has an effect on the view. But a yellow warning triangle appears next to the field I've changed and the next time I open this view I see the unmodified field. For example, if I change to landscape orientation the view goes back to default next time. Is there documentation some place on what these fields mean and how they are supposed to be used?

Android :: Preferences Use Explanation - Recommended Best Practice?

Oct 6, 2010

Some of my app's preferences could use some more explanation than the scarce space available for the summary. Sadly, there doesn't seem to be support from the system, like an optional help button that shows a longer text. How do you solve this problem? The first thing that comes to mind is an additional custom "preference" like "more information to above entry" that opens an AlertDialog with the help text, but that's not really nice for both user (two entries for the same preference) and the developer (manual work to do in Preference Activity). A bit nicer for the user, but way more work for the developer would be custom dialogs for each preference with more text and/or a help button. Is there a better solution or even an officially recommended best practice?

Android :: Simplest Way To Compile An Autotools Based Shared C Library For Droid?

Jul 16, 2010

I have a cross-platform C library that I need to compile for Android as a *.so file. The library consist of many .c and .h files, and it use autotools as it's buid system. (./configure && make dep && make). Afaik, the library does not depend on other libraries, other than libc and OpenSSL (which should be present on Andriod).

I'm trying to find the simplest (read fastest in terms or not needing to read hundreds of pages of manuals and then apply try && fail brute-force approaches to complete the task) way of getting the library off my machine in source code form, and into the Android phones as a .so. The library will eventually be accessed from Java's native library interface. For development, I have both Windows and Debian machines on my desk.

Android :: How To Get Specific Preference And Set Its Value?

Sep 23, 2010

I have the following code in my application in res/xml/preferences.xml:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="Wi-Fi settings">
<EditTextPreference
android:key="pref_voice_threshold_top"
android:title="@string/title_pref_voicetopthreshold"
android:dialogTitle="@string/dialog_title_pref_voicetopthreshold"
android:defaultValue="20" android:inputType="number"/>
</PreferenceCategory> </PreferenceScreen>

And I was wondering is it possible for me to then use this preference in code so I can update it via downloading an xml file? So I currently display the above preference in a PreferenceActivity, which works fine, however I want to be able to update the setting by downloading a new setting every week from the internet. So my question is how do I open this preference in code and set its value to the new downloaded value?

Android :: Mangled Preference Activity

Sep 24, 2009

I have pretty unassuming preferences screen based on Preference Activity. (You can see it in DroidIn app) I'm having some problems with it that I think have to do with redrawing the screen after updates. Here are the symptoms: 1. OnPreferenceChangeListener#onPreferenceChange if I change summary of the preference by doing Preference#setSummary the new value is painted over the old one creating unsightly effect 2. My preferences screen is large enough that user has to scroll. While scrolling, the whole screen get all messed up, again it looks like view is redrawn (when scrolled) without erasing the background first.

Android :: How Do You Create Custom Preference?

How should I proceed? I want to be able to use a activity for result intent with the PICK action.

Android :: ListPreference In Preference View

Jan 17, 2010

This is my first Android app (which is a soft keyboard, with dvorak layout) and so far it has gone pretty smoothly (either because or despite working from the sample code). I've had some problems (with special/swedish characters) that I've managed to take care of, but this problem I can't figure out how to solve..

But when I click the list item to edit it, i get an empty dialog (Title and button is shown right and with the text I set in the xml- file, but no list, screenshot: http://i49.tinypic.com/2501p55.png ). I can't see any problem with the program code (which isn't many lines..) or the xml (the arrays are generated by the Android utils in Eclipse and the preferences is a mix of auto and manual). You can see both Java code and XML here: http://pastebin.com/m4c52c3a2 (titles etc in Swedish..) (I've also tried a EditTextPreference item, which seemed to work fine..) I have also looked at the log/output using adb, and can't see any problems there either, so I have no idea onto how to solve this.

Android :: Where To Store Preference Keys?

May 18, 2010

When I create preference activity I define all preferences in xml file. Every preference has a key defined in this xml. But when I access preference I write:

SharedPreferences appPreferences = PreferenceManager.getDefaultSharedPreferences(this);
boolean foo_value = appPreferences.getBoolean("foo_key_defined_in_xml", false);

Is there any way to avoid referencing "foo_key_defined_in_xml" in hard-coded way? Maybe there is a possibility to reference it in R style way (not to refer to string)?

Android :: How To Declare Type Of Preference?

Mar 16, 2010

I have a preferences.xml that looks like this:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference android:name="Sample" android:enabled="true"
android:persistent="true" android:summary="Sample" android:defaultValue="3.0"
android:title="Sample" android:key="sample" /> </PreferenceScreen>

When I do sp.getString("sample", "3.0"), it works fine and returns a string, but it shouldn't be a string, it should be a float. Running sp.getFloat("sample", 3.0f) throws a ClassCastException because it is a string. What should I put in the XML so that the preference is stored as a float?

Android :: How To Get Pressed State Of Preference

Sep 10, 2009

There is know problem in all the Android phones. Go to Bluetooth Settings->Turn ON bluetooth->Click on bluetooth discovery->Then timer will start in summary->Long press on Bluetooth device discovery-> observe Bluetooth ON/OFF title start to toggle with Bluetooth Discovery toggle. I analyzed the issue. Blueooth ON/OFF is CheckBoxPreference. Bluetooth Discovery is also CheckBoxPreference which has dependency on Bluetooth ON/OFF. When we click on Bluetooth discovery then On thread will run at every second to update summary in Bluetooth Discovery preference. When we change the Bluetooth discovery to OFF then thread will be removed/ killed. When i press the Bluetooth discovery for long time when its already in ON State then still the thread will be updating the summary (remaining time from 120 to 00) till i press it. When i leave the Thread will stop. As it has dependency on Bluetooth ON/OFF, its making to the title invisible. But it should not happen. Solution: When i touch the Device Discovery i should kill the update summary thread then i guess, that problem will be solved. But in prefence i dont have any listener to know the pressed state. I hope somebody can give me solution.

Android :: GPS Lookup And User Preference

Aug 6, 2010

I'm starting to dip my toes into LocationManager. I've created a service which tracks GPS location (interval is more than 60000ms) and updates my application with user location so they can find stuff nearby. As I understand it, users can go into their preferences and disable GPS for a particular application. I would essentially like to offer my users two modes.
1) GPS. 2) If GPS can not pull, device does not have a GPS chip, or GPS is turned off for my app, I would like to allow them to type in their zip code (or maybe switch to cell tower lookup).

The bold text is what I'm interested in. How can I tell if the device does not have GPS? How can I tell if the user has disabled GPS for my application?
Side question: My service gets launched from my 2nd Activity. I call stopService in the onDestroy method of this Activity. If I back up to my 1st Activity and the 2nd Activity is destroyed, I still notice the GPS icon on my phone running. Is stopping the service sufficient? Or do I need to stop the LocationManager in the onDestroy of the service?

Android :: Intent Receiver According To Preference

Apr 9, 2010

I have a intent receiver in my android manifest, but would like to give the user the opportunity to choose whether he/her wants the app to automatically start at the specific state. Until now, I've used a service with a broadcast receiver, but I really want to delete this service as it seems a bit unnecessary.

Can register the intent action only if the user wants it (I guess not)? If not, should I make a class that will be called every time the intent is received and checks the user's preference or should I keep the service?

Android :: Leaked Window In Preference Activity

Jan 30, 2009

I've created a set of preference screens building on the tuts on androidguys. My preference XML contains nested PreferenceScreens. The below doesn't occur in the root screen, only once clicking to a child PreferenceScreen. Once in that PreferenceScreen, even before selecting an EditPreference, if I change orientation (i.e. flick the G1 keyboard out) I get an error: 01-30 09:33:54.080: ERROR/WindowManager(1261): android.view.WindowLeaked: that was originally added here.I have previously overcome this in other activities by utilising the onPause etc methods with custom dialogs I use. How can I prevent this in the PreferenceActivity? What am I missing?
