packages cannot be nested???

Report · Mar 12, 2013

HI, I am trying to compile my QR Code reader App using Adobe flash CS6, but keep getting the error "packages cannot be nested"

My code is as follows:

package

{

import com.logosware.event.QRdecoderEvent;

import com.logosware.event.QRreaderEvent;

import com.logosware.utils.QRcode.QRdecode;

import com.logosware.utils.QRcode.GetQRimage;

import net.hires.debug.Stats;

import com.bit101.components.*;

import flash.media.Sound;

import flash.display.*;

import flash.media.Camera;

import flash.media.Video;

import flash.events.*;

import flash.utils.Timer;

import flash.desktop.NativeApplication;

import flash.geom.Rectangle;

public class ReadQrSimple extends Sprite

{

private var detectionRate = 10;

private var getQRimage:GetQRimage;

private var qrDecode:QRdecode;

//string to save first decoded

private var qrDecodedDataOld:String;

private var timesCompleted = 0;

private var btnclear:BtnClear = new BtnClear();

var snd:Sound = new camerasound();

var readSuccess:Number = 0;

public function ReadQrSimple():void

{

displayDebugText();

// initialize the webcam

cam = Camera.getCamera();

if(cam != null)

{

cam.setMode(320,240,30);

refreshTimer.start();

}

else

{ txt.text = "Didn't find a webcam\n";

}

// display a guide where to put the marker

displayMarkerGuide();

// add Mr. Doobs Hi-ReS! stats

//addChild( new Stats() );

}

function onClear(event:MouseEvent):void{

trace("clear");

readSuccess = 0;

}

private function refresh( event:Event ):void

}

private function onQrImageReadComplete(e:QRreaderEvent):void

{

qrDecode.setQR(e.data);

qrDecode.startDecode();

}

private function onQrDecodeComplete(e:QRdecoderEvent):void

{ // e.data is the string decoded from QR Code

timesCompleted++; // number times of recognition since start of program

var decodedDataNew = e.data;

var compare = decodedDataNew.localeCompare(qrDecodedDataOld);

if(compare==0 && readSuccess == 0)

{ txt.text = String(timesCompleted)+"\t data: "+e.data+"\n"+txt.text;

snd.play();

myQRText.text = String(e.data);

readSuccess = 1;

}

else

{ txt.text = String(timesCompleted)+"\t ERROR \n"+txt.text;

}

qrDecodedDataOld = decodedDataNew;

}

private function displayMarkerGuide():void

{ markerGuide = new Sprite();

var guideLW:int = 5;

var guideColor:uint = 0xFFFFFF;

// make the MarkerGuide smaller than the markerArea

// in this case users don't have to put the marker that precise in the area for detection

var mRect = markerAreaRect;

mRect.inflate(-40,-40)

with(markerGuide.graphics)

{ lineStyle(guideLW, guideColor, 1, false, LineScaleMode.NONE, CapsStyle.SQUARE, JointStyle.MITER);

drawRect(mRect.x,mRect.y,mRect.width,mRect.height);

lineStyle();

beginFill(guideColor);

}

markerGuide.scaleX = 2.6;

markerGuide.scaleY = 2.0;

holder.addChild(markerGuide);

}

private function displayDebugText():void

{ txt = new TextArea();

txt.editable = false;

txt.width = stage.stageWidth-20;

txt.height = stage.stageHeight-700;

txt.x=10;

//txt.y=stage.stageHeight-txt.height-10;

txt.y=750;

//addChild(txt);

}

function QuitApplication(e:Event):void

{

trace("quit");

holder.removeChild(video);

cam = null;

NativeApplication.nativeApplication.exit();

}

IS THERE ANY ONE THAT CAN HELP, AS I AM NOT SURE WHERE I HAVE GONE WRONG!?!?

Thanks

there are no nested packages in that code.

search your class path(s) for another class file with the same name.

p.s. stop posting to the other thread with the duplicate post.

Are you writing this code on timeline in a frame or is it a distinct .as file?

If you you write this code on the timeline - you cannot do that. You must create separate .as files for every class.
