Android BitmapFactory.decodeStream(...) 不在模拟器上加载 HTTPS URL

Question

应用程序在模拟器上运行时不会从 HTTPS URL 加载图像。

示例代码:

URL url = new URL("https://someserver.com/photo.jpg");
mImageView.setImageBitmap(BitmapFactory.decodeStream(url.openStream()));

图像在实际设备上运行时加载得很好。如果通过 HTTP 而不是 HTTPS 访问图像，模拟器也会加载图像。

我是做错了什么还是这是一个已知问题？

使用以下代码在 imageview 中显示来自 url 的图像。

ImageView mImageView = (ImageView)findViewById(R.id.mImageView1);

URL url = new URL(address);
InputStream content = (InputStream)url.getContent();
Drawable d = Drawable.createFromStream(content , "src"); 
mImageView.setImageDrawable(d);

也可以使用下面的代码。

try {
    URL url = new URL(imageUrl);
    HttpGet httpRequest = null;

    httpRequest = new HttpGet(url.toURI());

    HttpClient httpclient = new DefaultHttpClient();
    HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);

    HttpEntity entity = response.getEntity();
    BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
    InputStream input = b_entity.getContent();

    Bitmap bitmap = BitmapFactory.decodeStream(input);

    ImageView mImageView = (ImageView) findViewById(R.id.mImageView);
    mImageView.setImageBitmap(bitmap);
} catch (MalformedURLException e) {
    Log.e("log", "bad url", t);
} catch (IOException e) {
    Log.e("log", "io error", t);
}
