java - Android install apk without asking user permission -


i building app kiosk mode purposes. device not rooted. app device administrator (android.permission.bind_device_admin) . want app able download , direct install other apks onto tablet without asking permission.

at moment using android downloadmanager download apk: then:

intent intent = new intent(intent.action_view);                                 intent.setdataandtype(uri.fromfile(new file(filepath)), "application/vnd.android.package-archive");                                 intent.setflags(intent.flag_activity_new_task); // without flag android returned intent error!                                 downloadmanageractivity.this.startactivity(intent);

to install apk. bring popup confirmation. theer away direct install apk after has been downloaded? thanks

update:

i came across post: https://paulononaka.wordpress.com/2011/07/02/how-to-install-a-application-in-background-on-android/

but not work , limited.

there no way install apk without popup confirmation. by-design security feature. phone vendors samsung offer options safe or knox allow installing without prompt, requires additional permissions , these technologies not available across android devices.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
