Hello all, got a rather unique question that I hope someone can shred some ideas.
What I am trying to do is the following:
1.) Run a particular android application that sends push notifications periodically.
2.) Convert the push notification into a CSV file and saved it in a Dropbox. folder. I can already sort of solved this via applications such as Automate, Tasker, Automagic, etc.
3.) Be able to run this application off an ANDROID EMULATOR installed on Windows and all ON a VPS.
One reason for running it on VPS is that I need this application with the push notifications to be "monitored" continuously for several hours a day, 5 days a week. It is EXTREMELY CRITICAL that I don't miss a single push notification from my end, so the VPS provides me with the guaranteed 99.99% uptime and is much more reliable than if were to run it off my own mobile phone. Another reason is that I will be using a VPS anyway to run another program (python FYI) that automatically reads the "CSV file" created from the push notification through Automate/Tasker/etc.
It is a unique situation, but I can't think of another way that could make use of the "text" from the push notifications received from this particular application. So any ideas would be great.
If all else fail, my fall back position is run it on a physical mobile phone, but I need to find ways to make sure it can achieve 99.9%+ internet uptime.
Thanks all!

Just out of curiosity does anyone know if any android devices can be affected by a fork bomb sent via text or email?
It is Linux so I'm guessing it will be affected. Maybe it won't be like OMG but it will be some what affected.
If a text or email could execute a custom script on being received, there is probably a lot worse that it could do than a fork bomb... Might be possible to get two views to keep calling each other, in which case the bundle for that program will expand until it runs out of memory and android will kill the app. This is very much an app specific bug though, and isn't related to the "fork bomb" of a program making a new instance of itself.
I thought Android runs on the sandbox environment for applications, which means the app can't execute much permissions as compared to Windows.
Just my $0.02
Yes, the apps are sandboxed for the most part.
Now that I think on it, there is a launch flag to open a new instance of a program leaving any currently running ones alone, which could be used to make a forkbomb. In this case, it would not be stopped by memory as the earlier instances will shut down but the exponentially increasing new instances will keep going, probably making the phone unusable until a reboot.
This can only be done by compiling and launching a signed app though, no email client can do this unless it has a backdoor to trigger this code from itself or from a trojan-esque feature to download, install, and launch apps on its own. The user would be promted to ok the new app's permissions anyway, unless it uses and gets permission for root access.
Basically, forkbombs are possible, but not by email or text with stock or nonmalacious programs.
Task Management
If the script gained root access, it'd be just the same as on a Linux machine. But I believe the DalvikVM simply kills any apps/processes it needs to in order to keep the system running smoothly (in theory).
well it works...

Id like to run 2 versions of a app is this possible? Id love to do this is a unrooted scenario but if its not possible my phones can be rooted.
My second question is how easy/safe would it be to simulate a button press externally? Looking for creative ideas here I need to hit a prompt once a hour on my phone. I dont want to use internal apps because im pretty sure those will get noticed.
Thanks!
You can, if you break an application to change the name of the package, replacing all the way to him to collect and re-sign. Get a new application. Of course, there may be problems with the treatment settings, databases, etc., but if the application is very simple, you can hire.
Is it feasible to do an app that automatically accesses the whatsapp key file, that from my understanding is located in /data/data/com.whatsapp/key, and sends it to a listener ip location, or by email?
To access that file, one has to have su privileges. So, could the app use a su command and prompt the user for authorization? The ideal would be to do it without rooting, like with a custom APK that managed the whole thing. ADBing the app from within the phone?
I think one could do this (with rooting :S) with metasploit, but it is quite a questionable tool to use, as my intentions are completely benevolent and I would like to make the script as direct and transparent as possible.
How could I do this? Any guidelines are hugely welcome!
TLDR: Got new phone, don't want to root now but still want to do things I needed root for. I need a non-root packet capture solution, or to decide if I should still root my new phone, or to get into development again. What is my best option? Use case below.
I have always rooted my phones which have always been as easy as 'fastboot oem unlock'. Not with ROG3. It needs an OEM tool and from what I read here I only get one chance.
After all the years though my uses of root fall into one of 3 categories: ad blocking, back up, and one specific case of packet capture.
I used AdAway for DNS level ad blocking. Private DNS with dns.adguard.com seems to be fine for that. Easy enough to set up.
Backup is with Titanium Backup. I am going to install all apps I ever had on my last phone (which has root and Ti) hoping that the stock transfer tool would pick them up and carry them over. Storage is not an issue; I have 512G. Apps I really don't care about anymore can be deleted later.
Next, my sticking point: Packet capture.
For that I have been running a tcpdump binary inside Terminal Emulator a week at a time. I am after the network traffic of one game, which I am not going to name for fear of ruining the fun. Its traffic has been in clear HTTP since I started playing in 2015. Through it I have gathered how units level up, enemy patterns in battles, and scripts for story scenes. I so enjoyed having these data that I kept playing, as long as it remains viable. My setup writes a pcap file to external storage that I can copy to my laptop for analysis. I configured tcpdump to capture only traffic to/from one IP to save space.
To get the same functionality I need a packet capture app to capture only the game's traffic, and save one pcap file per session. I tried 3 such apps and they all fall short in one way or another.
TPacketCapture captures all; app filter is its very expensive paid feature. Plus it stalls all traffic within 3 minutes of starting.
Greyshirts SSL Packet Capture splits capture by HTTP streams. Each must be selected manually for export with no option for a whole session export. Is a problem because every transaction of the game is its own HTTP stream. Is also a known beef among users and author seems unwilling to address. It keeps its data files to itself; I was only able to get them via root and they are not straight pcap, yet not difficult to figure out. It does decode the game traffic very nicely, to the point it becomes human-readable.
PCAPDroid does not save files; it only streams off its builtin HTTP server or UDP. I could not get useful capture out of it, but it is open source, so I could try adding that feature myself, hence the question of getting into development.
I did find a way to mass export data out of Greyshirts. I can use adb backup to back up that entire app's data. Then I found information on how to extract from it the data files it kept to itself. Then because those data is in a lighter format than pcap, it's actually easier for me to script a parser and work on them directly!
-- EDIT --
I found that some public wifi break if used with a private DNS.
Then for some time I totally lost adb backup functionality! I would get an empty backup even though everything else goes as expected. I resigned to defer moving that game over and set up Android Studio to start that development work I mentioned (in essence, attempt to modify PCAPDroid to save captures to external storage and add AdAway functionality).
Instead of using just the command line tools like I always have, I installed Android Studio. The SDK tools got updated along the way to 1.0.41 on SDK Tools 30.0.5 (I got the "ADB backup deprecated" message too, but the [email protected]% I care) . Then when I tried adb backup again I got my full backups again.
-- END EDIT --
I think there's my solution and I can now go without rooting. If I do need root in the future, adb backup should save the day.
Hi Guys,
I'm currently looking for a possibly very special app and can't find anything but the usual suspects like Tasker that don't seem to meet my requirements.
I'm looking for an automation app that allows me to navigate in apps, fill in text fields, if possible, transfer predefined data into the text fields for each run and wait for text to be entered at certain points.
For a better explanation:
I would like to test 2 apps and their behavior. Reset smartphones should be used for this. The automation app should run through the following steps:
- Step 1: The app creates an account with Gmail. As soon as the SMS code has been requested, the app should interrupt so that I can enter the SMS code. After confirmation, the app should continue to go through its routine.
- Step 2: Another app is to be opened that has a longer waiting time before it starts. Then text fields should again be filled in with predefined data.
- Step 3: Finally, the app should go to the settings and delete the G-Mail account.
I don't care how the whole thing is realized. Either macro recording again or using symbols as with Tasker. The main thing is that it works properly. I am not familiar with such an app. Just such simple apps as Tasker that work with if and while and are not sufficient for my purposes.
Otherwise, I had the idea to use Python to implement my dream routine. A few days ago I discovered a Python SDK for Android. If I understand correctly, the SDK is based on Python 3. I just can't estimate how well the programming is going or whether scripts can be executed 1: 1 as on the PC. What do you all mean? Do you know of an app that meets my expectations or should I deal directly with the Python method?
Nobody has an idea? Or is my text not understandable?
I know you said no "Tasker" like apps, but this app called Automate can definitely achieve what you outlined without any other apps (or with them). You only need android 7 or above and These function blocks:
The app uses a flowchart logical system (essentially the basis of all programming languages) and can even execute shell scripts with/without root privileges. You can also install Termux (a terminal emulator) and use the command:
Code:
pkg install python
To install python3.7, from there the world is in your hands, provided you have sufficient java/kotlin knowledge and an understanding for android processes.
Also please tick the check mark next to my answer if I solved your question, so that others can find the solution.
Thank you Slim K. Automate looks good at the first look. I'll give that app a chance and otherwise test thy python way with termux.
If there are other ways to solve the problem, let me know.
