how programmatically install ca certificate (for eap wifi configuration) in android?

how install ca certificate programmatically on android without user interaction

i came know cannot install certificate silently without user interaction.currently don't know how stop prompt each time user open app.

whenever application starts every time inquire user install certificate. there way can observe whether certificate(in case certificate) installed or not, programmatically.

code snippet have installing certificate in app

private void installcertificate() { seek { bufferedinputstream bis = new bufferedinputstream(getassets().open(my_cert)); byte[] keychain = new byte[bis.available()]; bis.read(keychain); intent installintent = keychain.createinstallintent(); x509certificate x509 = x509certificate.getinstance(keychain); installintent.putextra(keychain.extra_certificate, x509.getencoded()); installintent.putextra(keychain.extra_name, my_cert); startactivityforresult(installintent, install_keychain_code); } grab (ioexception e) { e.printstacktrace(); } grab (certificateexception e) { e.printstacktrace(); } } @override protected void onactivityresult(int requestcode, int resultcode, intent data) { if (requestcode == install_keychain_code) { switch (resultcode) { case activity.result_ok: dothetask(); break; case activity.result_canceled: finish(); break; default: super.onactivityresult(requestcode, resultcode, data); } } }

also fyi, installcertificate() called oncreate().

please help me out same. help appreciated.
