Android Keyevent injection requires system permissions -

-

hi using key event injection using window manager when tested application gives me error 

  04-12 18:19:35.794: warn/windowmanager(58): permission denied: injecting key event           pid 6290 uid 10039 window window{45034880      com.android.launcher/com.android.launcher2.launcher paused=false} owned uid 10020     04-12 18:19:35.794: warn/system.err(6290): java.lang.securityexception: injecting      application requires inject_events permission   04-12 18:19:35.854: debug/phonedata(6290):    04-12 18:19:36.048: warn/system.err(6290):     @    android.os.parcel.readexception(parcel.java:1247)    04-12 18:19:36.048: warn/system.err(6290):     @    android.os.parcel.readexception(parcel.java:1235)

i give inject event permission there way give application system permissions.

only applications part of firmware (i.e., signed firmware signing key) can hold inject_events permission. if making own device or firmware, relevant. if creating ordinary sdk application, cannot inject events.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
