В моем приложении я получаю android.os.NetworkOnMainThreadException
.
Я пытаюсь получить изображения с url в то время я получаю это Exception
.
Если я запускаю приложение в версии 2.2, он работает нормально, но если я запускаю в 4.0 утра получение исключения.
public static Bitmap getBitmap(String url)
{
Bitmap bitmap = null;
try
{
// replace space with url encoded character.
url = url.replace(" ", "%20");
// System.out.println("url : " + url);
URL urll = new URL(url);
InputStream in = (InputStream) urll.getContent();
bitmap = BitmapFactory.decodeStream(in);
}
catch ( MalformedURLException e )
{
e.printStackTrace();
}
catch ( IOException e )
{
e.printStackTrace();
}
if ( bitmap == null )
bitmap = BitmapFactory.decodeResource(resources, R.drawable.noimage);
return bitmap;
}
Я получаю ошибку в
InputStream in = (InputStream) urll.getContent();
в этой строке, пожалуйста, помогите мне решить эту проблему.
Я использовал AsyncTask
private class RecipeDetail1Task extends AsyncTask<Long, Void, RecipeDetailBean>
{
@Override
protected void onPreExecute()
{
Log.i(TAG, "<<<<<<<<<<<<<onPreExecute>>>>>>>>>>>>>>>>>>>");
btnViewRecipe.setEnabled(false);
imgFree.setVisibility(View.GONE);
}
@Override
protected RecipeDetailBean doInBackground(Long... params)
{
Log.i(TAG, "<<<<<<<<<<<<<doInBackground>>>>>>>>>>>>>>>>>>>");
RecipeDetailBean bean = null;
try
{
ParserUtil pu = new ParserUtil(ParserUtil.ResultControl.LIMITED);
bean = pu.getRecipeDetail(params[0]);
}
catch ( ParserConfigurationException e )
{
e.printStackTrace();
}
catch ( SAXException e )
{
e.printStackTrace();
}
return bean;
}
protected void onPostExecute(RecipeDetailBean result)
{
Log.i(TAG, "<<<<<<<<<<<<<onPostExecute>>>>>>>>>>>>>>>>>>>");
Constant.recipeDetail = result;
if ( result == null )
{
Log.i(TAG, "<<<<<<<<<<<<<result == null>>>>>>>>>>>>>>>>>>>");
toast.setText(getString(R.string.recipe_detail_not_present_message));
toast.setDuration(Toast.LENGTH_LONG);
toast.show();
Constant.recipeDetail = new RecipeDetailBean();
btnViewRecipe.setEnabled(false);
}
else
{
Log.i(TAG, "<<<<<<<<<<<<<result |= null>>>>>>>>>>>>>>>>>>>");
//pb.setVisibility(View.INVISIBLE);
btnViewRecipe.setEnabled(true);
lblRecipeName.setText(result.getName());
lblRecipeDesc.setText(result.getDescription());
lblRecipeBy.setText(result.getAuthor());
lblPostedOn.setText(result.getCreatedDate());
String d=Integer.toString(result.getServedNumber());
if(d==null)
{
lblServesNumber.setText("N/A");
lblServesNumber1.setText("");
}
else if(result.getServedNumber()==0)
{
lblServesNumber.setText("N/A");
lblServesNumber1.setText("");
}
else
{
lblServesNumber.setText(d);
lblServesNumber1.setText(" Adult(s)");
}
if(Constant.recipeDetail.getFreeYN() == 1)
imgFree.setVisibility(View.VISIBLE);
//rbRecipeRating.setProgress((int) result.getRating());
rbRecipeRating.setRating((float) ( (result.getRating() * 5) / 100 ));
//Log.d("rating2", "" + (float) ( (result.getRating() * 5) / 100.0f ));
result.setRecipeBitmap(Constant.getBitmap(result.getImageURL()));
imgRecipe.setImageBitmap(result.getRecipeBitmap());
imgRecipe.setVisibility(View.VISIBLE);
//ImageLoader imageLoader = new ImageLoader(imgRecipe, pb, null);
//imageLoader.execute(result.getImageURL());
}
btnViewRecipe.requestFocus();
}
}
Я получаю ошибку в этой строке:
result.setRecipeBitmap(Constant.getBitmap(result.getImageURL()));
