[android-developers] Shared Preferences
Hi, what is the difference betweent PreferenceManager.getDefaultSharedPreferences and getSahredPreferences(String name, int mode) ? I thought that the defaultSharedPreferences are someting like global preferences that every application can manipulate. So lets say that I can call a preference from another application in my own application, and even change it. And the getSharedPreferences are preferences that I can only use in my application. Thats just what I thougt it is...but I'm not sure. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Shared Preferences
Hi,
The code itself is fine except that you don't print the exception.
If you would log the exception you can see (in the LogCat) that the
run-time is throwing some kind of a ParseException.
This is since users (usually) don't type 'L' at the end of their numeric
input, even when it's long.
Hope this helps

Re: [android-developers] Shared preferences and integer values
Most probably your Int_Value doesn't exist. In this case the number you
specified, 200, will be assigned instead.
Thanks

[android-developers] Shared preferences and integer values
Hello.
Iam using shared preferences to store some values.
final SharedPreferences pref = getSharedPreferences("MyPref",
MODE_PRIVATE);
final SharedPreferences.Editor edit = pref.edit();
edit.putInt("Int_value", 1);
edit.putString("String_Value", "test string");
edit.commit();
i look in the xml file and everything is saves as it should.
now i grabb the values:
int i = pref.getInt("Int_Value", 200);
String s = pref.getString("String_Value", "");
and now i wanna add it to a text label:
I have this in top of my code
final TextView test = (TextView) findViewById(R.id.test);
and then if i wanna show the string everything works as it should.
test.setText(s);
if i try to show the int value with this
test.setText(i);
then my application make a force close, so i thougt that the problem
was that i had to make the int a string so i did like this
test.setText(Integer.toString(i));
now the program wotk but it does not show my stored value it shows me
the in this case 200 becourse of
int i = pref.getInt("Int_Value", 200);
I must be missing something simple here i quess.
could someone point it out for me?

[android-developers] Shared preferences in a library
I made a library that I access and use across my app.
My code looks something like this:
package com.android.foobar;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
public class Library{
int someVar;
public Library() {
SharedPreferences settings =
PreferenceManager.getDefaultSharedPreferences(this);
someVar = settings.getInt("someVar", 435);
}
public int otherMethodes(){
return someVar; //not important
}
}
--
Now, I want to use the shared preferences to get some settings and use
them for doing calculations in my lib, and I've been trying but can't
get a valid context to use in getDefaultSharedPreferences(). Any ideas?

[android-developers] Shared preferences not accessible in service
Hello Android, We are using SharedPreferences(Not default preferences.) to store our application related settings. These settings are not accessible in the background service as the application context is different from service context. It always returns the default values. We want to have our own UI to manage settings. So, we don't want to use PreferenceActivity. Is there a way or hack to access SharedPreferences from inside a service which are created by application?
