java - file exists but in toast it's empty -


the toast says file exists, after read response empty. can mistake?

thanks

filename = "locations.txt"; file file = new file(environment.getexternalstoragedirectory()             .getabsolutepath() + "/doma/" + filename);      string response = "";      if (file.exists()) {         toast.maketext(this, filename + " exists", toast.length_short).show();         bufferedreader br;          try {             br = new bufferedreader(new inputstreamreader(new fileinputstream(file), "cp1252"));             (string line; (line = br.readline()) != null; response += line + '\n') ;         } catch (filenotfoundexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }         toast.maketext(this, "read:\n" + response, toast.length_short).show();     } else {         toast.maketext(this, "sorry, " + filename + " doesn't exist!!", toast.length_long)                 .show();     }

if referring response set empty toast.maketext(this, "read:\n" + response, toast.length_short).show();

your toast must file , not filename .. value of filename?

file file = new file(environment.getexternalstoragedirectory()             .getabsolutepath() + "/doma/" + filename);      string response = "";      if (file.exists()) {         toast.maketext(this, filename + " exists", toast.length_short).show();         bufferedreader br;          try {             br = new bufferedreader(new inputstreamreader(new fileinputstream(file), "cp1252"));             (string line; (line = br.readline()) != null; response += line + '\n') ;         } catch (filenotfoundexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }  toast.maketext(this, "read:\n" + response, toast.length_short).show();                 .show();     } else {      toast.maketext(this, "sorry, " + file + " doesn't exist!!", toast.length_long)     }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
