[android-developers] Re: Strange StringIndexOutOfBoundsException with TextView(stacktrace contains supportTabandEmoji)

Hi

So maybe the TextView is modified by manufacturer.

Going down your stack trace, the first method I can't find in the source is TextView.onMeasure2 and searching Google for "TextView.onMeasure2" (without the "") turns up some hits that look like they are from China.

Hi

My application 's error log in google play shows many StringIndexOutOfBoundsException.

I want to find the root cause, but it's really hard for me. Because it happens at render time.

So there is not any my method in stacktrace.  

my stacktrace looks like this.

        java.lang.StringIndexOutOfBoundsException
        at java.lang.String.getChars(String.java:1059)
        at android.text.SpannableStringInternal.getChars(SpannableStringInternal.java:102)
        at android.text.TextUtils.getChars(TextUtils.java:101)
        at android.text.Layout.processToSupportEmoji(Layout.java:3747)
        at android.text.Layout.supportTabandEmoji(Layout.java:3783)
        at android.text.Layout.measureText2(Layout.java:3141)
        at android.text.Layout.getDesiredWidth2(Layout.java:183)
        at android.text.Layout.getDesiredWidth2(Layout.java:161)
        at android.widget.TextView.onMeasure2(TextView.java:5925)
        at android.widget.TextView.onMeasure(TextView.java:6138)
        at android.view.View.measure(View.java:8363)
        at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:3169)
        at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1048)
        at android.widget.LinearLayout.measureHorizontal(LinearLayout.java:732)
        at android.widget.LinearLayout.onMeasure(LinearLayout.java:342)
        at android.view.View.measure(View.java:8363) 

        ....

And I can't find supportTabandEmoji in android git repository.

My TextView's content sometimes has some ImageSpan, but it depends on use's input, so I don't know what textview set actually.

Did some one see this error before? And is there any work around for this problem?

thanks
