Android BitmapFactory.decodeStream(...)在模拟器上无法加载HTTPS URL[英] Android BitmapFactory.decodeStream(...) doesn't load HTTPS URL on emulator

本文是小编为大家收集整理的关于Android BitmapFactory.decodeStream(...)在模拟器上无法加载HTTPS URL的处理/解决方法,可以参考本文帮助大家快速定位并解决问题,中文翻译不准确的可切换到English标签页查看源文。

问题描述

应用程序在仿真器上运行时不会从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()));

在实际设备上运行时,图像加载即可.如果通过HTTP而不是HTTPS访问,则仿真器也加载图像.

我做错了什么,或者是一个已知的问题吗?

推荐答案

imageview中使用以下代码从URL中的显示图像.

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);

也使用以下代码.

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);
}

试用此代码:

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;
           }
         }

和请确保您在清单文件中添加了 Internet权限. 这将有助于你这样做.

问题描述

App doesn't load an Image from an HTTPS URL when run on the emulator.

Sample code:

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

The image loads just fine when run on an actual device. Also the emulator loads the image if it's accessed via HTTP instead of HTTPS.

Am I doing something wrong or is this a known issue?

推荐答案

Use below code for display image in imageview from url.

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);

And also use below code for that.

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);
}

Is this a trusted https site? If not you will have a problem with the connection.

Try this code:

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;
           }
         }

And pls make sure u have added internet permission in your manifest file. This will help u to do so.
