我的代码是：

gridView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        Media clicked = adapter.getItem(position);

        String url = Backend.BASE_MEDIA_URL + clicked.url_big;

        Log.d("Media", url);

        Intent intent = new Intent();  
        intent.setAction(android.content.Intent.ACTION_VIEW);   
        intent.setDataAndType(Uri.parse(url), "image/*");  
        startActivity(intent);  
    }
});

我100％肯定网址是正确的。提前谢谢。

编辑：清单文件，我删除了一些无关的活动

每次我想使用Android中的内置图库来显示来自网络的图片时，我都会收到此错误

首先，没有单一的“build in gallery”应用程序。有数百个设备，他们将有各种“内置画廊”应用程序。

其次，除了浏览器之外，您的设备上没有任何内容能够“显示来自网络的图像”，并且只有当您让Android确定实际的具体MIME类型时才会这样。不要求任何设备的“内置图库”应用程序支持使用它来下载和显示图像的第三方应用程序。

从web获取图像时出现android.content.ActivityNotFoundException
