Question

我在android上的ti.paint模块有错误。每当我尝试设置图像时，我的应用程序崩溃（在iOS上运行正常）我尝试了几个代码：

var paintView = Paint.createPaintView({
    top:0, right:0, bottom:80, left:0,
    image : "images/doge.png",
    eraseMode : true,
    strokeWidth : 70
});

和

image : "/images/doge.png"

也

image = "http://dogr.io/doge.png"

最后

var dogeFile = Titanium.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'images/doge.png');
var paintView = Paint.createPaintView({
    top:0, right:0, bottom:80, left:0,
    image : dogeFile.nativePath,
    eraseMode : true,
    strokeWidth : 70
});

但是应用程序每次都在Android上崩溃（在iOS上运行正常）。

我也尝试过使用jpeg图像，甚至是NULL值。

以下是我在控制台中收到的错误消息

我正在运行Titanium SDK 3.2.3.GA。

任何帮助都将不胜感激。

我目前正在使用ti.paint，我遇到了与Android相同的问题。 Android的管理视图与Titanium的管理视图不同，这就产生了问题...... 想法是使用主线程。

这里是PaintViewProxy.java模块的变化：

@Kroll.setProperty
@Kroll.method
public void setImage(String imagePath) {
    final String imgPath = imagePath;
    getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            paintView.setImage(imgPath);
        }
    });
}

重新编译它应该有效，它对我有用。我希望你有帮助...
