第二篇、Android Supersu 屏蔽权限请求通知 SuReceiver广播

标签：

我们想要去定制Supersu 让其，过滤掉我们自己的应用，不显示权限提醒。我们可以来看看这个su调用系统发送广播。然后我们的Supersu.apk会收到弹窗的广播。我们可以在这里进行拦截过滤。

public class SuReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, Intent intent) {
        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);

        //这里可以对super日志输出的拦截，过滤掉不想打印日志的应用
        UidPolicy u = SuperuserDatabaseHelper.addLog(context, le);

        String toast;
        if (UidPolicy.ALLOW.equals(action)) {//这里将会弹窗超级应用授权，我们可以在这里判断，让他不显示Toast提示
            toast = context.getString(R.string.superuser_granted, le.getName());
        }
        else {
            toast = context.getString(R.string.superuser_denied, le.getName());//拒绝用户的请求
        }

        if (u != null && !u.notification)
            return;

        switch (Settings.getNotificationType(context)) {//是否显示弹窗等。
        case Settings.NOTIFICATION_TYPE_NOTIFICATION:
            NotificationCompat.Builder builder = new NotificationCompat.Builder(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;
}

下一篇，

下一篇将介绍如何屏蔽授权Acitivty的确认通知 

通过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"

这个我发现，su是通过，shell命令来启动一个权限请求的Acitivty这个就是我们所看到的 权限提醒界面。
