android – RemoteViews for widget update exceeds max bitmap memory usage error

Posted by: admin June 15, 2020 Leave a comment

Questions:

I have a widget that parses xml feed and display its title and image.In this widget I am using a service that periodically changes the contents(ie, title and image).For this I am using timer class.When we run this widget, some contents are displayed without any problem but after sometime it force closes and shows an error like “RemoteViews for widget update exceeds maximum bitmap memory usage(used:2465280 max:2304000) The total memory can’t exceed that required to fill the device’s screen once”. Please some one help me to solve this issue…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");

                        }
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (DOMException e) {

            }
     }

}

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();








    }

How to&Answers:

I just solved a similar problem.
But I wasn’t loading any content from web.
My widget was displaying different images for different widget sizes. And for some screens there was the same error as yours displaying widget 4×4.

That what I’ve found at developer.google.com:

The total Bitmap memory used by the RemoteViews object cannot exceed
that required to fill the screen 1.5 times, ie. (screen width x screen
height x 4 x 1.5) bytes.

So I was able just to put a restriction on my bitmap size in widget to fit this requirement.

In your particular case the error occures when a bitmap loading from stream is larger than possible.

I think the ussage of

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

with proper options should help. (possible you need to use inSampleSize option).

Hope my post was helpful.

Answer:

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

….

the override(…) did the trick for me.
No more errors like:
RemoteViews for widget update exceeds max bitmap memory usage error
