NoClassDefFoundError - Android 2.3.X -

-

i have task defined in class. fatal exception "noclassdeffounderror" happening on following line 

mycutetask mytask = new mycutetask(equations)

here code

public class myclass  {      public void run() {         mycutetask mytask = new mycutetask(equations)     }      protected class mycutetask extends  asynctask<string, integer, string> {         ...     } }

recently, have strange bug reports. android throw exception when instantiate task. have bug android 2.3.x only.

do of got same bug?

edit: here stack trace

line @ com.mathssolver.main.logic.updategraph(logic.java:310) is

 mycutetask mytask = new mycutetask(equations)

its google play services issue. (https://code.google.com/p/android/issues/detail?id=81083)

workaround avoid crash till google fixes it:

add following application#oncreate() method 

try {   class.forname("android.os.asynctask"); } catch(throwable ignore) {   // ignored }

note application#oncreate() , not activity#oncreate()

update: can verify above changes fixed these crashes me.

any ideas when firefox implement lengthadjust andtextlength?..... working svg application. lengthadjust , textlength working fine in chrome not working in fire fox . <svg viewbox = "0 0 500 300" version = "1.1"> <defs> <path id="s3" d="m 10,90 q 100,15 200,70" /> </defs> <g> <text font-size = "20"> <textpath xlink:href="#s3" textlength="205"> short text</textpath> </text> <use xlink:href="#s3" fill="none" stroke="black" stroke-width="1"/> </g> </svg> this implemented in firefox text elements (not textpath or tspan) in case that's ok though can move attribute text element. <svg viewbox = "0 0 500 300" version = "1.1"> <defs>
