RemoteViews for updating widget exceeds maximum bitmap memory usage error

I have a widget that parses an XML stream and displays its title and image. In this widget, I use a service that periodically changes the content (i.e. the title and image). To do this, I use the timer.When class, we launch this widget, some content is displayed without any problems, but after that it forces to close and shows an error, for example: "RemoteViews for updating the widget exceeds the maximum use of raster memory (used: 2465280 max: 2304000). The total memory may not exceed the time required to fill the device screen once. " Please help me solve this problem ... Thanks in advance

Here is my AppwidgetProvider =>

public class myappwidgetprovider extends AppWidgetProvider { public static String urls="http://www.abc.com/en/rssfeeds/9/latest/rss.xml"; // XML node keys static final String KEY_HEAD = "item"; // parent node //static final String KEY_TITLE = "title"; static final String KEY_DATE = "pubDate"; public static String headflag="english"; public static String[] Title; public static String[] Description; public static String[] Tit; public static String[] Tit2; public static String[] Desc; public static String[] Desc2; public static String[] image; public static TextView flashnews; public static int i=0; public void onUpdate( Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds ) { Log.i("Tag", "onCreateView"); parse(); RemoteViews remoteViews; ComponentName thisWidget = new ComponentName(context,myappwidgetprovider .class); int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); Intent intent = new Intent(context.getApplicationContext(), Updatewidget.class); intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds); context.startService(intent); } public static void parse() { URL url; try { url = new URL(urls); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); if((conn.getResponseCode() == HttpURLConnection.HTTP_OK)){ DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc; doc = db.parse(url.openStream()); doc.getDocumentElement().normalize(); NodeList itemLst = doc.getElementsByTagName("item"); Description = new String[itemLst.getLength()];//........ Title = new String[itemLst.getLength()]; Tit=new String[itemLst.getLength()]; Tit2=new String[itemLst.getLength()]; Desc=new String[itemLst.getLength()]; Desc2=new String[itemLst.getLength()]; image= new String[itemLst.getLength()]; for(int i=0; i < itemLst.getLength(); i++){ Node item = itemLst.item(i); if(item.getNodeType() == Node.ELEMENT_NODE){ Element ielem = (Element)item; NodeList title = ielem.getElementsByTagName("title"); NodeList date = ielem.getElementsByTagName("pubDate"); NodeList description = ielem.getElementsByTagName("description"); Tit[i]= title.item(0).getChildNodes().item(0).getNodeValue(); Desc[i]= description.item(0).getChildNodes().item(0).getNodeValue(); Tit2[i]=Translate.title(Tit[i]); Desc2[i]=Translate.description(Desc[i]); if(headflag=="malayalam") { Desc2[i]=Desc2[i].replace("read more","IqSpXÂ"); } Title[i] =Tit2[i]; if (Desc2[i].contains("<img ")){ String img = Desc2[i].substring(Desc2[i].indexOf("<img ")); String cleanUp = img.substring(0, img.indexOf(">")+1); img = img.substring(img.indexOf("src=") + 5); int indexOf = img.indexOf("'"); if (indexOf==-1){ indexOf = img.indexOf("\""); } img = img.substring(0, indexOf); //setImgLink(img); if(headflag=="malayalam") { String img2=img.replace("files","files/imagecache/android_320"); Description[i]=Desc2[i].replace(img,img2); image[i]=img2; } else { String img2=img.replace("files","files/imagecache/android_1_img"); Description[i]=Desc2[i].replace(img,img2); image[i]=img2; } } else { Description[i] =Desc2[i]; } } } } } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (DOMException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ParserConfigurationException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

And here is my service =>

 public class Updatewidget extends Service { static String UPDATEMOOD ="UPDATEMOOD"; public Intent newintent; public AppWidgetManager app; public RemoteViews newviews; public int[] newappid; int i=0; @Override public void onStart(final Intent intent, int startId) { Log.i("Tag", "Service Called!!!!!!!!!!!!!"); newintent=intent; int[] allWidgetIds = intent .getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS); newappid=allWidgetIds; final AppWidgetManager appWidgetMan = AppWidgetManager.getInstance(this); app=appWidgetMan; final RemoteViews views = new RemoteViews(this.getPackageName(),R.layout.widget_main); newviews=views; views.setTextViewText(R.id.title, myappwidgetprovider.Title[0]); Bitmap bitmap; try { bitmap = BitmapFactory.decodeStream((InputStream)new URL(myappwidgetprovider.image[0]).getContent()); views.setImageViewBitmap(R.id.imageView4, bitmap); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } appWidgetMan.updateAppWidget(allWidgetIds, views); new ProgressAsyncTask().execute(); } public class ProgressAsyncTask extends AsyncTask<Void, Integer, Void> { @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub int delay = 5000; // delay for 5 sec. int period = 5000; // repeat every sec. Timer timer = new Timer(); timer.scheduleAtFixedRate(new TimerTask() { public void run() { i++; if(i==5) { i=0; } int[] allWidgetIds = newintent .getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS); newviews.setTextViewText(R.id.title, myappwidgetprovider .Title[i]); Bitmap bitmap; try { bitmap = BitmapFactory.decodeStream((InputStream)new URL(myappwidgetprovider .image[i]).getContent()); newviews.setImageViewBitmap(R.id.imageView4, bitmap); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } app.updateAppWidget(allWidgetIds, newviews); } }, delay, period); return null; } } @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } }

I just solved a similar problem. But I did not download content from the Internet. My widget showed different images for different widget sizes. And for some screens there was the same error as your 4x4 widget.

What I found on developers.google.com:

The total Bitmap memory used by the RemoteViews object cannot exceed which was supposed to fill the screen 1.5 times, i.e. (screen width x screen height x 4 x 1.5).

That way, I was able to simply limit the size of the bitmap in the widgets to fit this requirement.

In your particular case, an error occurs when the bitmap download from the stream is more than possible.

I think using

public static Bitmap decodeStream (InputStream is, Rect outPadding, BitmapFactory.Options selects)

with the correct parameters. (maybe you need to use the inSampleSize parameter).

Hope my post was helpful.

  Glide.with(mContext) .load(imageUrl) .override(480, 342)

....

redefinition (...) helped. No more errors: RemoteViews for updating a widget exceed the maximum memory usage error in raster memory
