Android :: Account Preferences Crashes On ListPreference
May 14, 2010
I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working. I have added the line android:accountPreferences="@xml/account_preferences" to my account-authenticator and account_preferences.xml looks like so:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="@string/alum_settings_title"/>
<CheckBoxPreference
android:key="sync_alum"
android:title="@string/sync_alum"
android:summaryOn="@string/sync_alum_check"
android:summaryOff="@string/sync_alum_nocheck"/>..................

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences).
Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

I'm trying to understand remote services at the moment and everything works fine, i can start the service and know how to communicate with it through the AIDL-interface. My problem is that the service seems to still run in the same process like the activity it was started from, because the activity crashes too, if there is an error thrown in the Service.
I set the service process to remote ( android:process=":remote" ) so what am i doing wrong? Or what do i have to do to unbind the service-process completely from the activity-process?

When using a PreferenceActivity to do preferences, the PreferenceScreen can contain a ListPreference. A ListPreference has an array of keys and an array of values. But the PreferenceActivity only writes the values to SharedPreferences. How do I get the key of the item selected from the list? I would have thought this is pretty fundamental, especially if you want to translate your app.

My android application has two kinds of preferences:
1) I have user preferences defined in res/xml/preferences.xml so that users can manage their preferences with a PreferenceActivity.
2) I'd like to define another file for global configuration preferences of my app.
What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?

I'm using listpreference in my android app and getting my key values and all is well and works good (now that you guys have helped me) BUT - when my listpreference menus popup, they only contain a cancel button. Let's say the user is choosing between red, blue, and green. When the listpreference dialog first pops-up, the dialog only shows a cancel button. Because of that, the dialog disappears as soon as the user selects their choice. I would like it so that when the user chooses their setting, they see the radio button get highlighted and then they go ahead and click the ok button...but I don't have an ok button and can't figure out why.

Is there a way to use a custom row for the ListPreference in the Android preference screen? Currently I populate the ListPreference like this, but I need more info (description) shown in the List
int count = items.size();
CharSequence[] entries = new CharSequence[count];
CharSequence[] entryValues = new CharSequence[count];
for (int i = 0; i < count; i++) {
entries[i] = items.get(i).toString();
entryValues[i] = String.valueOf(i);
}
langPref.setEntries(entries);
langPref.setEntryValues(entryValues);

I want to put a ListPreference in my preference screen. But all the examples I have found in Internet the content are loaded out of a xml and I need that de options in the ListPreference are dynamic and not previously defined (in a xml).
I have mi preferences.xml in the folder xml/ of my project;
this is the code of preferences.xml:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android

I have an XML preferences screen which is handled by addPreferencesFromResource. On it, there is a ListPreference, for which I want the summary to contain the current value of that preference. I think this would be a common requirement, as otherwise you could not see the present value of the preference without expending a click. I read that the summary field supports resource references, and I see that I can refer to preferences as android:summary="@+preference/prefname" in my ListPreference. Clearly this is why resource references would be supported in this field. However, when I try this, instead of the present value of prefname, the text "false" appears as the summary. Does anybody know how to display a current value without taking the seemingly ridiculous step of rewriting the entire (large) preference screen in Java?

I'm trying to set a defaultValue to a ListPreference item. Here is an sample of my preference.xml file:
<ListPreference android:key="notification_delai"
android:title="@string/settings_push_delai"
android:entries="@array/settings_push_delai_human_value"
android:entryValues="@array/settings_push_delai_phone_value"
android:defaultValue="????">
</ListPreference>
The two arrays:
<string-array name="settings_push_delai_human_value">
<item>every 5 minutes</item>
<item>every 10 minutes</item>
<item>every 15 minutes</item>
</string-array>.............

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.

I am resuing ListPreference for a setting which I store in the database. I do not want it stored in the preference file. How can I reuse ListPreference in such way that it does NOT save to SharedPreference file?

I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?)

I'm betting im missing one small thing. I've looked on the developer site and i've read some tutorials and i'm just not seeing what i did wrong. I'm trying to use a ListPreference to decide which sound to play on a button click. I have this at the top:
public String greensound;
Here's my OnClick code:
case R.id.green:
SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(this);
greensound = prefs.getString("greensound", "gsone");
if (greensound == "gsone") {
mSoundManager.playSound(1);
} else if (greensound == "gstwo") {...................

I have a ListPreference with the entries and entryValues correctly set. When I go in the prefernces activity and change the value it successfully works (I added a Toast to output the value after changing the option to test). But when I do the following to compare it, it always executes the else statment when I change it everytime, even like above when I changed the ListPreference and the value was "bluesky" it still failed to execute the correct if statement. Here's the code I use to check the value of the ListPreference in the onResume():
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this)
String backgroundPref = prefs.getString("backgroundPref", "");
if(backgroundPref == "bluesky"){
mainLayout.setBackgroundResource(R.drawable.bluesky);
Toast.makeText(getBaseContext(), "Blue Sky", Toast.LENGTH_SHORT).show();
}else if(backgroundPref == "sky"){
mainLayout.setBackgroundResource(R.drawable.sky);
Toast.makeText(getBaseContext(), "Sky", Toast.LENGTH_SHORT).show();
}else{
mainLayout.setBackgroundResource(R.drawable.sunsetscene);
Toast.makeText(getBaseContext(), "Sunset Scene", Toast.LENGTH_SHORT).show();
}
The Toasts are there so I can double check which statement gets executed, and it always seems to be the else one. Am I having a bad day and getting something wrong?

I have this at the top:

Here's my OnClick code:................
I also tried removing the default value here it didnt seem to change anything but, should it be removed?
Here's my Settings.java:
package com.my.app;
CODE:...........
And here's my array's if that will help at all:
CODE:............
Here's a logcat that kinda looked possibly related:
CODE:..........
For those that might ask here's my DDMS > File Explorer > Data > Data > packageName > SharedPreferences This is what was in there:
com.my.app_preferences.xml:
CODE:...................
This all really confuses me more because...It looks like greensound does == gsone so.... I don't understand whats wrong its not even playing the default sound. and yes i've tested all this code without the listpreference code and they work great. I'm not sure what's wrong?

I want to have an element in my preference menu that does the following: Show a list of options. Many are selectable Maximum amount of options to be chosen 2. Possibilities I thought of: Doing a separated PreferenceScreen and showing options as checkBoxes but I don't know where to place the logic of max 2 options. Extending DialogPreference and doing it by hand.

I am trying to put together a modal box with a scrollable list of checkable items and an OK and Cancel button at the bottom for the user to select filters from. It seems the simplest way to do things like this in Android is to reuse API components (widgets, layouts, etc) and the closest one I can find to this looks to be the ListPreference, which basically does exactly what I want (I can even work with storing the data in SharedPreferences). The problem is that I'm not launching this modal box from a PreferenceActivity, but rather will be launching it from either of two activities: a ListActivity and a MapActivity.

I'm setting out to create a settings activity for my app. I've defined a PreferenceActivity with a nice layout including a ListPreference object for the user to select a bluetooth device. I'm having trouble dynamically populating the list. I would like to populate ListPreference with values from an array adapter (which I'll create and populate with relevant bluetooth device names). If this were a spinner View, I could just call setAdapter(). However with the ListPreference object I can't figure out how to attach an adapter (findviewByID won't cast from View To ListPreference, so I can't even get a handle to the object). I would like to attach an adapter and then populate the adapter with values, which in turn would populate the ListPreference with values.

And I want to get the value with something like: int val = sharedPrefs.getInt(key, defaultValue).
At the moment I have to use getString and parse the result.

I am attempting to add a simple preferences file in a new Android project (New -> Android XML File), but it doesn't appear to be working correctly.
There is no root element to choose from when I select the Preference type layout. If I press Finish, it doesn't do anything. See screenshot below.
