Percent character in String.format() is obtained by specifying "%%" (two
percent signs).
http://download.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html
( search for "percent", where it says "The result is a literal '%'" )
But I bet you already knew that :)
On the other hand, this requires that the string pass through Format to
produce the single percent sign, which it doesn't for stock Android source.
How about you create a subclass of ListPreference, override getSummary,
and return whatever you need, skipping the call to String.format(),
effectively undoing the CM change.
As a side note, that's custom firmware for you. Users probably love the
feature to see the current list entry in every application, but it seems
so insignificant compared to a possible crash. And no try/catch block in
the modified version either...

Reviving an old [degenerate] thread, rather than creating a new one...
I've been getting occasional UnknownFormatConversionException error
reports in my Dev Console, and had no idea what they were from. Today
I think I've figured it out, because it's occurring reliably on my
Honeycomb device.
Turns out it happens when there's a "%" character in a string resource
used as a label in a PreferencesActivity. Seems that the system thinks
it's going to be a format specifier, tries to evaluate it as such,
fails, and then falls over. But in my case, it's not; I'm letting the
user specify a pref for transparency of an AppWidget, with options
like 25%, 50%, etc.
I'm not sure how to fix it yet, and I'm open to suggestions. I tried "/
%", like you do for an apostrophe char, but that didn't work at all.
Tried "%" (the entity for "%"), but apparently that gets evaluated
too early, and the same problem occurs. If all else fails, I could
just use "percent", but that's kind of hokey.
Any other ideas?

android.preference.ListPreference.getSummary(ListPreference.java)
It happens only on Cyanogen's firmware when there's "%" symbol in
ListPreference's summary.
If u will open ListPreference.java from Froyo's sources u wouldn't
find method ListPreference.getSummary, so it looks like ListPreference
uses base method from Preference.java:
public CharSequence getSummary() {
return mSummary;
}
And javadoc's from eclipse it confirms that:Returns the summary of
this Preference.
Ok, now let's open ListPreference.java from Cyanogen's sources:
public CharSequence getSummary() {
final CharSequence entry = getEntry();
if (mSummary == null || entry == null) {
return super.getSummary();
} else {
return String.format(mSummary, entry);
}
}
It look's like it's Cyanogen's feature (only 8 bug reports from>3000
users), but let's go
tohttp://developer.android.com/reference/android/preference/ListPrefere...
Returns the summary of this ListPreference. If the summary has a
String formatting marker in it (i.e. "%s" or "%1$s"), then the current
entry value will be substituted in its place.
WHAT IS GOING ON HERE???
Can someone explain how *exactly* getSummary works?
