Question

当我长按我的自定义网页浏览时，会显示以下错误： -

java.lang.NullPointerException
at android.webkit.WebViewClassic.showSelectActionWindow(WebViewClassic.java:1974)
at android.webkit.WebViewClassic.access$8100(WebViewClassic.java:279)

启动操作模式时出错： public ActionMode startActionMode（ActionMode.Callback callback）{

    Log.d("dic","STARTING ACTION MODE");

    if(callback == null){  
        Log.d("longpress","callback is null");
        return null;
    }
    /*
     * Related to XC-929
     * if the new UI proposal is approved use this

     *
     **/
    if(callback.equals(mActionModeCallback)){
        Log.d("longpress","callback is equal");
        selectedText=getSelectedText();

        if(mActionMode == null){
            mActionMode = super.startActionMode(callback);
        }

        return mActionMode; 
    }

    if(isTablet){

            Log.d("longpress","callback is different");
            if(mActionMode == null){
                mActionMode = startActionMode(mActionModeCallback);


        }
            return mActionMode;
    }
    else {
        mActionMode = null;
        return null;
    }
}

，错误是： -

  STACK_TRACE=java.lang.NullPointerException

我在网上搜索没有关于webviewClassic的内容。它仅在三星s3 4.3和所有其他设备上显示此错误，相同的代码工作正常。请建议我任何解决方案的线索。感谢
