The easiest way to download image from URL is to use
main.xml:
Java file:
method Drawable.createFromStream
:main.xml:
<linearlayout android:id="@+id/LinearLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <imageview android:id="@+id/ImageView1" android:layout_height="wrap_content" android:layout_width="wrap_content"> </imageview></linearlayout>
Java file:
import java.io.InputStream; import java.net.URL; import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.widget.ImageView; public class ImageFromUrlExample extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView imgView =(ImageView)findViewById(R.id.ImageView1); Drawable drawable = loadImageFromWeb("http://www.example.com/android.png"); imgView.setImageDrawable(drawable); } private Drawable loadImageFromWeb(String url) { try { InputStream is = (InputStream) new URL(url).getContent(); Drawable d = Drawable.createFromStream(is, "src name"); return d; }catch (Exception e) { System.out.println("Exc="+e); return null; } } }
Hi,
ReplyDeleteThis works for me most of the time, but createFromStream() sometimes returns null on certain URLs. What can I do?
Thanks,

Yes, I discovered that yesterday as well. I can't believe it hasn't been fixed yet. I used a workaround that seems t work okay.
