java - Downloading Large file to certain directory from within app using DownloadManager -


i have application needs able download ~3gb file user specified location, have below code, seems work. i.e download takes place showing in download manager etc.

however once download complete fails appear in correct location, , space has not been taken @ all.

this current code:

 public void file_download(string url) { install_txt = apppreferences.getprefs().getstring(                 "path",                 environment.getexternalstoragedirectory().getpath()                 + "/test.img");              downloadmanager mgr = (downloadmanager) this.getsystemservice(context.download_service);              uri downloaduri = uri.parse(url);             downloadmanager.request request = new downloadmanager.request(                     downloaduri);              request.setallowednetworktypes(downloadmanager.request.network_wifi)                     .setallowedoverroaming(false).settitle("test")                     .setdescription("downloading test")                     .setdestinationinexternalpublicdir(environment.directory_downloads , install_txt);              mgr.enqueue(request);         }

so question why above not work well? or download manager struggles download such large files? if case there better method use download reliably such large file

after download finishes below shown in logcat

07-19 13:19:28.112: w/downloadmanager(19199): exception id 8952: invalid int: "3891000000" 07-19 13:19:28.112: w/downloadmanager(19199): java.lang.numberformatexception: invalid int: "3891000000" 07-19 13:19:28.112: w/downloadmanager(19199):   @ java.lang.integer.invalidint(integer.java:138) 07-19 13:19:28.112: w/downloadmanager(19199):   @ java.lang.integer.parse(integer.java:378) 07-19 13:19:28.112: w/downloadmanager(19199):   @ java.lang.integer.parseint(integer.java:366) 07-19 13:19:28.112: w/downloadmanager(19199):   @ java.lang.integer.parseint(integer.java:332) 07-19 13:19:28.112: w/downloadmanager(19199):   @ com.android.providers.downloads.downloadthread.handleendofstream(downloadthread.java:516) 07-19 13:19:28.112: w/downloadmanager(19199):   @ com.android.providers.downloads.downloadthread.transferdata(downloadthread.java:314) 07-19 13:19:28.112: w/downloadmanager(19199):   @ com.android.providers.downloads.downloadthread.executedownload(downloadthread.java:278) 07-19 13:19:28.112: w/downloadmanager(19199):   @ com.android.providers.downloads.downloadthread.runinternal(downloadthread.java:193) 07-19 13:19:28.112: w/downloadmanager(19199):   @ com.android.providers.downloads.downloadthread.run(downloadthread.java:142)

that error message suggest downloadmanager, @ present, limited files 2147483647 (integer.max_value) bytes or smaller.

there has been a bug report filed already, no response google @ present.

in meantime, i'd see if arrange split ~3gb file 2 smaller files. if not, may need downloading yourself.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
