memory - What is an Efficient way to load apk icons in Android? -


i working on small file manager helping me learn android development , ran few issues loading apk icons apk files. trying load icon assoicated apk. planning on loading in adapter.

here method using: 

  public bitmap getapkbitmap(file f) {         packageinfo packageinfo = getcontext().getpackagemanager().getpackagearchiveinfo(f.getabsolutepath(), packagemanager.get_activities);         applicationinfo appinfo = packageinfo.applicationinfo;         if (build.version.sdk_int >= 8) {             appinfo.sourcedir = f.getabsolutepath();             appinfo.publicsourcedir = f.getabsolutepath();         }         drawable icon = appinfo.loadicon(getcontext().getpackagemanager());         bitmap bmpicon = ((bitmapdrawable) icon).getbitmap();         return bmpicon;     }

problem:

it works ok, problem whenever have lot of apks, or scroll little fast, app crashes , run few memories. plus whenever scrolling, laggy , isn't smooth @ all.

you need implement lazylist show images on demand. solve memory problem.

another thing consider scale images down if big. solve laggy list problem.
