Android, backspace doesn't work properly in a flash.text.TextField

[pol2095]

Hello,

I have a bug on my Nexus 5 Android 4.4 Air 4.0.

when I scroll the text in the textField and I select the text (in my example near "subclass" word), the TextField get focus, if I put on the backspace key, the character deleted is the previous character the first time, and if I put again on the backspace key, the caracter deleted is the first character and not the previous character.

package{
import flash.text.TextField;
import flash.display.Sprite;
import flash.events.Event;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
public class Main extends Sprite {
  private var myTextField:TextField = new TextField();
  public function Main() {
    stage.scaleMode = StageScaleMode.NO_SCALE;
    stage.align = StageAlign.TOP_LEFT;
    addEventListener(Event.ADDED_TO_STAGE, init);
  }
  private function init(event:Event):void {
    myTextField.type="input";
    myTextField.text="The TextField class is used to create display objects for text display and input. You can give a text field an instance name in the Property inspector and use the methods and properties of the TextField class to manipulate it with ActionScript. TextField instance names are displayed in the Movie Explorer and in the Insert Target Path dialog box in the Actions panel.\nTo create a text field dynamically, use the TextField() constructor.\n\nThe methods of the TextField class let you set, select, and manipulate text in a dynamic or input text field that you create during authoring or at runtime.\n\nActionScript provides several ways to format your text at runtime. The TextFormat class lets you set character and paragraph formatting for TextField objects. You can apply Cascading Style Sheets (CSS) styles to text fields by using the TextField.styleSheet property and the StyleSheet class. You can use CSS to style built-in HTML tags, define new formatting tags, or apply styles. You can assign HTML formatted text, which optionally uses CSS styles, directly to a text field. HTML text that you assign to a text field can contain embedded media (movie clips, SWF files, GIF files, PNG files, and JPEG files). The text wraps around the embedded media in the same way that a web browser wraps text around media embedded in an HTML document.\n\nFlash Player supports a subset of HTML tags that you can use to format text.

[nimitja]

We are not able to reproduce the issue. Could you plesae share the application.xml that you used in your project.

Regards,

Nimit

[pol2095]

I use the default application.xml.

steps to reproduce

scroll the text to "subclass" word

put on the textField, the cursor appear and the soft keyboard, put on the backspace key

"subclass" -> "subclas", put again on the backspace key

"subclas " -> "subclas" => bug, put again on the backspace key

the cursor disappear

scroll to the top of the text and see the cursor at position 0

@nimitja

Are you able to reproduce this issue ?

[nimitja]

We are still not able to reproduce the issue. We need to check this once again with new Google Keyboard 3.0 as mentioned above. We will update you on this soon.

Nimit

[pol2095]

I have the same bug in AVD of the Android sdk

steps to reproduce :

- launch Eclipse of the Android sdk -> Window -> Android Virtuel Device Manager

- Device Definitions -> select Nexus 5 -> Create AVD... -> Android 4.4.2 - API Level 19 -> ARM (armeabi-v7a) -> uncheck Hardware keyboard present -> No skin -> RAM 1907 -> check Use Host GPU

- Start...

- launch the CMD on Windows

- adb install -l C:\Users\user\Desktop\Clavier_Google_3.0.19373.1072412a.apk (I find it in my Nexus 5, you can download it at http://pol2095.free.fr/Google_Keyboard_3.0.19373.1072412a.apk)

- launch the Google Keyboard on AVD

- adb install -l C:\Users\user\Desktop\TextFieldApp.apk and test the bug (TextFieldApp.apk exported with a captive runtine)

We are able to reproduce the issue now with Google Keyboard 3.0 and now investigating it.

Thanks for reporting.
