facebook - Blogger - How to Percent Encode an URL / Escape It to Use as Query Param? -


in blogspot template engine how escape post url use query param can use in facebook / twitter / whatever buttons , iframes?

problem: have iframe src takes url.

<iframe src="https://www.facebook.com/plugins/like.php?href=my_url_goes_here">

so post url http://example.blogspot.com/1999/01/first.html. need convert :/. percent encoded characters, , ?&% etc. otherwise this:

<iframe src="https://www.facebook.com/plugins/like.php?href=http://example.blogspot.com/1999/01/first.html">

and looks it's going break someday. how can escape url in blogger?

the way pretty simple , takes wasting couple of hours searching every corner of internet semblance of documentation on blogspot's template engine , reading through bunch of stackoverflow's answer dismiss question "use shareurl instead."

anyway. every string in blogspot templates has .escaped field string escaped. it. anyurl.escaped , works. can data:post.url.escaped or data:post.url.canonical.escaped or whatever.

<iframe   expr:src="&quot;https://www.facebook.com/plugins/like.php?href=&quot;     + data:post.url.canonical.escaped + &quot;width=173&amp;layout=button_count&amp;action=like&amp;size=small&amp;show_faces=false&amp;share=true&amp;height=46&amp;appid=your_app_id_here&quot;" width="173" height="46" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowtransparency="true"></iframe>

other elusive string attributes can found in extremely fishy blog: http://template-data.blogspot.com.br/2016/04/title_58.html

you'd think google have info somewhere easy find got blogger http api docs? what?

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...
