java - Saving multiple images from URLs -


i'm trying save multiple images bought through in-app billing. 

      new thread(new runnable() {             @override             public void run() {                      string path = getfilesdir().getabsolutepath();                     file imagefile = new file(path, "image.png");                      fileoutputstream fos = null;                 //i'm sorry mess you're witness                 if(!imagefile.getname().equals("image.png")) {                     try {                         imagefile.createnewfile();                         fileoutputstream ostream = new fileoutputstream(imagefile);                         bitmap.compress(bitmap.compressformat.png, 100, ostream);                         ostream.close();                         log.d(tag, "image saved" + fos.tostring());                     } catch (exception e) {                     }                 }                 else if(imagefile.getname().equals("image.png"))                 {                     try {                         imagefile = new file(path, "image2.png");                         imagefile.createnewfile();                         fileoutputstream ostream = new fileoutputstream(imagefile);                         bitmap.compress(bitmap.compressformat.png, 100, ostream);                         ostream.close();                         log.d(tag, "image2 saved" + fos.tostring());                     } catch (exception e) {                     }                 }                 else if(imagefile.getname().equals("image2.png"))                 {                     try {                         imagefile = new file(path, "imag3.png");                         imagefile.createnewfile();                         fileoutputstream ostream = new fileoutputstream(imagefile);                         bitmap.compress(bitmap.compressformat.png, 100, ostream);                         ostream.close();                         log.d(tag, "image2 saved" + fos.tostring());                     } catch (exception e) {                     }                 }                }             }).start();     }      @override     public void onbitmapfailed(drawable errordrawable) {}      @override     public void onprepareload(drawable placeholderdrawable) {} };

so have saves 1 image, can't save more 1. i'm looking store max of 20 in long term , 5 in short term.

this why buy button. if 1 of buttons clicked download image, image file name download internal storage image2.png.

 else if (purchase.getsku().equals(item_sku_1)) {              //sets buy button false;             loadbutton(buybutton);             picasso.with(purchaseactivity.this)                     .load(itemskuimageurl)                     .into(target);          } else if (purchase.getsku().equals(item_sku_2)) {             loadbutton(buybutton2);             drawable d  = getbitmapfromurl(itemskuimageurl);             //string encoded = imagetobytearray(bm);                  picasso.with(purchaseactivity.this)                         .load(itemskuimageurl)                         .into(target);

i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...
