Second, Android SUPERSU blocking permission request notification Sureceiver broadcast

We want to customize the Supersu so that it filters out our own apps and does not show permission reminders. We can take a look at this SU call system to send broadcasts. Then our supersu.apk will receive the broadcast of the pop-up window. We can do interception filtering here.

public class Sureceiver extends Broadcastreceiver {@Override public void OnReceive (final context context, Intent in                Tent) {if (intent = = null) return;        String command = Intent.getstringextra ("command");        if (command = = null) return;        int uid = Intent.getintextra ("UID",-1);        if (uid = =-1) return;        int desireduid = Intent.getintextra ("Desired_uid",-1);        if (Desireduid = =-1) return;        String action = Intent.getstringextra ("action");        if (action = = null) return;        String fromname = Intent.getstringextra ("From_name");        String desiredname = Intent.getstringextra ("Desired_name");        Final LogEntry le = new LogEntry ();        Le.uid = UID;        Le.command = command;        Le.action = action;        Le.desireduid = Desireduid;        Le.desiredname = Desiredname;        Le.username = FromName; Le.date = (int) (System.currenttimemillis ()/1000);        Le.getpackageinfo (context);        Here you can intercept the Super log output, filter out applications that do not want to print the log uidpolicy u = superuserdatabasehelper.addlog (context, le);        String Toast; if (UidPolicy.ALLOW.equals (action)) {//Here will pop the window Super app authorization, we can judge here, let him not show toast prompt toast = context.getstring (r.string.s        Uperuser_granted, Le.getname ());  } else {toast = context.getstring (r.string.superuser_denied, Le.getname ());//Deny user's request} if        (U! = null &&!u.notification) return;        Switch (settings.getnotificationtype (context)) {//Whether the popup window is displayed, and so on. Case Settings.NOTIFICATION_TYPE_NOTIFICATION:NotificationCompat.Builder Builder = new Notificationcompat.build            ER (context); Builder.setticker (Toast). Setautocancel (True). Setcontentintent (pendingintent.getactivity (context, 0            , New Intent (), 0). Setcontenttitle (Context.getstring (R.string.superuser)). Setcontenttext (Toast) . Setsmallicon (R.drawable.ic_stat_notification);            Notificationmanager nm = (Notificationmanager) context.getsystemservice (Context.notification_service);            Nm.notify (notification_id, Builder.getnotification ());        Break            Case Settings.NOTIFICATION_TYPE_TOAST:Toast.makeText (context, TOAST, Toast.length_short). Show ();        Break }} private static final int notification_id = 4545;}

by su.c

#include "Su.h"


/* Intent Actions */
#define Action_request "Start", "-N", requestor "/" Requestor_prefix ". Requestactivity "
#define ACTION_NOTIFY "Start", "-N", requestor "/" Requestor_prefix ". Notifyactivity "
#define ACTION_RESULT "Broadcast", "-N", requestor "/" Requestor_prefix ". Sureceiver "


#define Am_path "/system/bin/app_process", "/system/bin", "Com.android.commands.am.Am"

This I found, Su is through, shell command to start a permission request Acitivty This is what we see the permission alert interface.
