[英]Fetching image from url in Android
I am trying to Fetch image from Url, but i'm getting I/O exception. 我正在尝试从网址获取图片,但是我遇到了I / O异常。 I really have no idea why. 我真的不知道为什么。
try {
URL profilePicUrl = new URL("http://houssup.netau.net/vivek_thumbnail.jpg");
HttpURLConnection connection =(HttpURLConnection) profilePicUrl.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream inputStreamImage = connection.getInputStream();
Bitmap profileImage = BitmapFactory.decodeStream(inputStreamImage);
holder.profilePic.setImageBitmap(profileImage);
} catch (MalformedURLException e) {
Log.e("Profile Image","Error in URL");
e.printStackTrace();
} catch (IOException e) {
Log.e("Profile Image","Error in IO");
e.printStackTrace();
}
Also i want to make point that, HttpURLconnection is throwing exception everywhere in my app. 我也想指出一点,HttpURLconnection在我的应用程序中到处都引发异常。 I mean in every class, I am not able to use this class. 我的意思是在每个班级中,我都无法使用该班级。
I tried that code and the error is this: 我尝试了该代码,错误是这样的:
Caused by: android.os.NetworkOnMainThreadException 造成原因:android.os.NetworkOnMainThreadException
so the solution is to include this on your code: 所以解决方案是将此包含在您的代码中:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
