android - How to add a ring around the custom image marker pointing down on the map without using drawable file -

want marker in image. have made custom marker circular image unable add ring around circular image pointing down programmatically.

private googlemap mmap;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_maps);     // obtain supportmapfragment , notified when map ready used.     supportmapfragment mapfragment = (supportmapfragment) getsupportfragmentmanager()             .findfragmentbyid(r.id.map);     mapfragment.getmapasync(this);  }   /**  * manipulates map once available.  * callback triggered when map ready used.  * can add markers or lines, add listeners or move camera. in case,  * add marker near sydney, australia.  * if google play services not installed on device, user prompted install  * inside supportmapfragment. method triggered once user has  * installed google play services , returned app.  */ @override public void onmapready(googlemap googlemap) {     mmap = googlemap;      bitmap scaled = bitmap.createscaledbitmap(bitmapfactory.decoderesource(getresources(),             r.drawable.ab), 120, 120, true);      bitmap image=getcircularbitmap(scaled); 

// modify canvas // canvas1.drawbitmap(scaled, 0,0, color);

    // add marker in sydney , move camera     latlng sydney = new latlng(-34, 151);     markeroptions markeroptions = new markeroptions();     markeroptions.position(sydney);     markeroptions.icon(bitmapdescriptorfactory.frombitmap(image));      mmap.addmarker(markeroptions);     mmap.movecamera(cameraupdatefactory.newlatlng(sydney)); }  public bitmap getcircularbitmap(bitmap bitmap) {     bitmap output;      if (bitmap.getwidth() > bitmap.getheight()) {         output = bitmap.createbitmap(bitmap.getheight(), bitmap.getheight(), bitmap.config.argb_8888);     } else {         output = bitmap.createbitmap(bitmap.getwidth(), bitmap.getwidth(), bitmap.config.argb_8888);     }      canvas canvas = new canvas(output);      final int color = 0xff424242;     final paint paint = new paint();      final rect rect = new rect(0, 0, bitmap.getwidth(), bitmap.getheight());      float r = 0;      if (bitmap.getwidth() > bitmap.getheight()) {         r = bitmap.getheight() / 2;     } else {         r = bitmap.getwidth() / 2;     }      paint.setantialias(true);     canvas.drawargb(0, 0, 0, 0);     paint.setcolor(color);     canvas.drawcircle(r, r, r, paint);     paint.setxfermode(new porterduffxfermode(porterduff.mode.src_in));     canvas.drawbitmap(bitmap, rect, rect, paint);      return output 

developers required use drawables passed thru bitmapdescriptorfactory indicated in documentation. ring around image should part of image itself, if multi-colored (like on image provided), can use multiple templates markers.

hope helps!
