android - Listactivity error with jelly bean running device ( SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length) -
i have app start splash screen open listactivity rows, clicking on row opens activity containing textview, 2 buttons (one of opens infinite gallery, other opens custom dialog), , menu items (about, preference, exit).
this app runs on ginger bread when tested on galaxy s3 running jelly bean, opens when click on 1 of listactivity rows appears ignore click. log cat on eclipse shows :
span_exclusive_exclusive spans cannot have 0 length however, there no force close (the listactivity scrolls , menu items work fine , ).
update:
noticed application: created eclipse since around 1 month ago name lets (trip) , today testing (trip.apk) on both ginger bread , jelly bean works perfectly.
but wanted change name trip travel , did not use refactor. instead created new project application name called travel other things same previous app trip including classes, res, , when tested jelly bean shows:
span_exclusive_exclusive spans cannot have 0 length update 3 :
i solved problem :
i added line textviews in app :
android:textisselectable="true" and line lead rows ignore click ,
so removed , both old , new app work fine both api .
update 4:
the above phrases related old issue , solved ,
the question :
my application work apis when tested with:
galaxy s3 running jelly bean work ,
but in eclipse log cat show error :
span_exclusive_exclusive spans cannot have 0 length without affect application performance , idea solve error .
any explanation highly appreciated , thanks.

to understand happening here, starts design decision textview should , shouldn't be. according the android source textview:
/** * displays text user , optionally allows them edit it. textview * complete text editor, basic class configured not * allow editing; see {@link edittext} subclass configures text * view editing. this means that, if you're doing putting piece of text on screen, hidden behind full text highlight, selection , editing facilities. has happened here little tweak resolve issue in them appears have interfered other functionality, , created log lines. case given more weight by, say, nexus 7 error "span_exclusive_exclusive spans cannot have 0 length", in seem on android versions situation can resolved disabling autocomplete in text (entry) fields:
view.setinputtype( inputtype.type_class_text | inputtype.type_text_flag_no_suggestions ); this done in xml using corresponding tags textview:
android:inputtype="none" the lines in question appear have arrived in android 4.1 (jelly bean), in setspan function of spannablestringbuilder (eg. 2.2.3 source vs 4.1.1 source). log line triggered attempt set span within string of 0 length. why setting no (sub) section of text needs selected should avoid error, either above tip or using:
android:textisselectable="false" android:editable="false" a more speculative solution maybe ensure there never blank string in textview adding character "\u200b" (a non-shown blank character of 0 width) every string put in textviews, either overriding settext (to add end of string) in custom textview or putting in code every string sent textviews.
for delving android system , overriding parts of it, according this piece of android source looks mght possible solve issue following. however, there absolutely no guarantee works. brave (foolhardy) can write complete spannablestringbuilder ....
creating own form of
spannablestringbuildertraps condition. example stops quietly, rather stopping loudly, per original:import android.text.spannablestringbuilder; public class myspannablestringbuilder extends spannablestringbuilder { // taken spannablestringbuilder.java private static final int mark = 1; private static final int point = 2; private static final int start_mask = 0xf0; private static final int end_mask = 0x0f; private static final int start_shift = 4; myspannablestringbuilder() { super(); } myspannablestringbuilder(charsequence text) { super(text); } myspannablestringbuilder(charsequence text, int start, int end) { super(text, start, end); } @override public void setspan(object what, int start, int end, int flags) { // determine if error going triggered, if fail silently int flagsstart = (flags & start_mask) >> start_shift; int flagsend = flags & end_mask; if (flagsstart == point && flagsend == mark && start == end) { return; } // good, call real routine super.setspan(what, flagsstart, end, flagsend); } }creating
myeditablefactory extends editable.factory, setting return spannablestringbuilder:import android.text.editable; public class myeditablefactory extends editable.factory { private static myeditablefactory sinstance = new myeditablefactory(); /** * returns editable factory. */ public static editable.factory getinstance() { return sinstance; } public editable neweditable(charsequence source) { return new myspannablestringbuilder(source); } }
other writing custom version of os , putting on phone, i'm not sure else possible.
all suggestions improvement welcome, feedback on using code in various os situations.
