Android BitmapFactory.decodeStream（...）不會在仿真器上加載HTTPS URL

Question

在仿真器上運行時，應用程序不會從HTTPS URL加載圖像。

示例代碼：

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

圖像加載就好當實際設備上運行。如果通過HTTP而不是HTTPS訪問圖像，模擬器也會加載圖像。

我做錯了什麼或者這是一個已知的問題？

使用以下代碼顯示來自url的imageview中的圖像。

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); 

而且還使用下面的代碼。

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); 
}

這是一個可信任的https站點嗎？如果沒有，您將會遇到連接問題。

試試這個代碼：

imageView.setImageBitmap(LoadImageFromWebOperations(url)); 

private Bitmap LoadImageFromWebOperations(String url){ 
      try{ 
      String encodedurl = url.replace(" ", "%20"); 
      InputStream is = (InputStream) new URL(encodedurl).getContent(); 
      Bitmap d = BitmapFactory.decodeStream(is); 
      return d; 
      }catch (Exception e) { 
      e.printStackTrace(); 
//   System.out.println("Exc="+e); 
      return null; 
      } 
     } 

和PLS確保ü已經在你的清單文件添加Internet權限。 這將幫助你這樣做。
