TextView with ellipsize middle casues "ArrayIndexOutOfBoundsException" Exception

Question

Edited:

I am getting java.lang.ArrayIndexOutOfBoundsException: Exception for a TextView with ellipsize middle. Here is my TextView

        <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="25dp"
        android:layout_marginRight="25dp"
        android:ellipsize="middle"
        android:maxLines="1"
        android:paddingLeft="10dp"
        android:paddingRight="27dp"
        android:text="123456 123 1234567890123456"
        android:textSize="16sp" />

I have experimented with this Exception and its causing for calculateEllipsis() method with this given margin, padding,textSize and singleLine.

Here is CrashLog

Here is some scenario where i am not getting Exception

If i remove the last character( set text "123456 123 123456789012345" removed '6' from last ) then i don't get Exception
If i set textSize 14sp then i don't get any Exception
IF i set ellipsize="end" it worked fine.
Its working fine in high resolution devices with same TextView properties.

I think making ellipsize middle with the large last word "1234567890123456" (16 character) caused This Exception.

Here is my device Specification:

Model: HUAWEI Y320-U30
Android Version: 4.2.2

Can anyone explain whats wrong with calculateEllipsis() method with this scenario.

Thanks in advance.

I got my answer. It's a bug for pre lolipop device if i use both android:ellipsize="middle" and android:maxLines="1" . The solution is to use android:singleLine="true". This prevent my crash. Here is the bug report . You can also check this answer
