AirDroid for Android

Must try for Android Addicts
Managing your Android phone or tablet does not mean that you have to establish a physical connection – providing you have a copy of AirDroid installed. With this app in place on your Android device, all you then need is a web browser; it does not matter which web browser you use or whether you are running OS X, Linux or Windows. Launch the app and you will be provided with both a URL and an IP address that you can use to establish a remote connection along with a pass code for security.
Once this has been entered you’ll be presented with a virtual desktop for your device. This is not an emulator, so you will not be working with a representation of your phone or tablet, but you will be able to browse through its contents and even make use of various features. You can quickly see how much space you have left available both on internal storage and your memory card and you can see how this space is taken up by different types of file.
There is a great file browser that can be used to view the contents of your device, but also enables you download files to your computer or upload them to your phone or tablet. Drag and drop support is a great feature and you can also install and uninstall apps with ease, including setting up batch operations to help get things completed more quickly.
Other great features include a shared clipboard that can be used to copy and paste text between computer and Android. You can also view your call logs, control your ringtone settings and control your music from your computer. If your device is rooted, you have a handy screenshot tool on your hands, but there’s plenty to keep you busy even if you haven’t take this step.
Verdict:
A superb way of managing your Android device and transferring files in both directions.

I have AirDroid and ApMobile on a Galaxy Note GT-N7000. The N7000 is unlocked and has Android vers 4.0.4. AirDroid says it can 'remove' ApMobile but this is contrary to other links.
Is it safe to do this, please? Thanks for help.

Just wondering if there are many vulnerabilities though. Lots of app permissions that might not be necessary..

I used it since a year now, very useful app, writing sms with a keyboard ^^

[Q] How can I access the hidden "Application Data" in my Google Drive?

I found this page[1], which describes a hidden folder in Google Drive that is used by apps to store hidden data that other apps cannot access. How can I access this data myself? If there is no official way to do this (which seems likely), how about an unofficial way? I'm okay if such a method requires a rooted device, such as to get keys or something from an app's data. (Perhaps there's an Xposed module that can intercept these API calls to obtain the required authentication data in a universal manner?)
The reason I don't think there's an official way is because of this page[2] about the Saved Games API, namely this part:
Read/Write isolation
All Saved Games are stored in your players' Google Drive Application Data Folder. This folder can only be read and written by your game - it cannot be viewed or modified by other developers’ games, so there is additional protection against data corruption. In addition, Saved Games are insulated from direct tampering by players so they cannot modify individual Saved Games.

I'd like to be able to "tamper" (as Google calls it) with that save data anyway, as it's my own save data after all. Most likely this method would let me access that as well.
Could someone point me in the right direction please? Thank you!

[Q] Android inventory app data storage suggestions

Hello,
I'm attempting to make an inventory application. Basically, our company has several devices/equipment that we checkout to other people and our current paper system isn't working out. The devices will each have an NFC tag put on that uniquely identifies it, and the idea is that the Android application on our smartphones (provided by the company) will simply scan it to check in/out the device. It will record the date time, who checked it out, and other information, and we want more than one person to be able to check in/out items at a time.
My problem is figuring out a way to store this data. Our company already pays for a OneDrive for Business account and our initial idea was to simply store the data in an Excel spreadsheet and share it with the people who checkin/checkout the devices (only two people at the moment), then the app would download the spreadsheet, record the new data, and upload it again to OneDrive. Reading and writing the data is easy, but actually pulling the file from OneDrive is where we hit a road bump and now we need another plan.
Are there any free alternatives for data storage of this kind where I would be able to access it through the Android application and update it? We also thought of using Heroku, but through researching I found that directly connecting to the PostgreSQL database they provide within the application is not possible. Of course we want to keep this data secure and only accessible to the people actually checking in/out devices, but we do not need a huge amount of space to store this data. Any suggestions are greatly appreciated.

Heroku is a good option. You'll have to make an app to run API's that will talk to your app.

Anything we need to do about the latest WPA2 vulnerabilities that were found?

This is the story I'm referring to for those who haven't heard yet.
I just got my Note 8 on Saturday and did get a carrier update later in the day, not sure if it was related to this. Anyone have any info on what we need to do or are we waiting for AT&T/Samsung to release a patch?
From the link:
As a result, all Android versions higher than 6.0 are also affected by the attack, and hence can be tricked into installing an all-zero encryption key. The new attack works by injecting a forged message 1, with the same ANonce as used in the original message 1, before forwarding the retransmitted message 3 to the victim. In each case, the attacker can force a targeted device to re-install an already-in-use shared key, downgrading the key.

This will require an update from Samsung. Not holding my breath on that happening anytime this year.

Avoid public wifi like the plague. Even after the patch I'd stay away from it.
Also this includes turning on your hotspot in public. At least until a patch is pushed out.
That will keep you safe for about 6 months until the next bug is discovered. It's the nature of IT security.
One thing that is a great idea and an awesome feature on Samsung is the "Secure Folder" app.
You can use it to store pictures, files, apps, etc. They are encrypted by the KNOX container and require a pin or password to open the secure folder.
If you move let's say, your private pictures, your banking app, and any sensation files (eg credit cards, ID, passport, etc) into the app even if your phone gets compromised you should be okay.
*as a disclaimer I work in ISO for a fortune 100 company. More than will to offer any advice about protecting your phone, computer, wifi etc.

Thanks I didn't think about using the Secure Folder. I just moved (not copied) a photo into there to test it but the photo still shows up in the gallery, yet I don't see it when browsing for it from within the Secure Folder.
When something is within this folder, can it still be accessed from outside the app or do you always need to open the app, type in the password and then access it? Like could I still attach photos from there easily into a message/email or do I need to go in there, move them out of the folder, attach them, them move them back? Hope that makes sense.

No if it moved correctly it should be hidden unless you are in the secure folder.

Unsolved tech...

Hello guys,
I have been searching for answers to some of the tech stuff, but couldn't find them.
Here are some of those questions. Hope some of you would have answers to these. Thanks in advance!
ANDROID
1. How to share files between multi-users on Android 11?
Before Android 11, it was possible to save files inside the Android/ obb folder, and these files were visible for all users on the device. In Android 11, this is no longer working as the 'obb' folder appears to be exclusive to each user.
I know this is possible via USB OTG or a cloud service, but is there a solution without these?
2. How to copy/ backup game data for non-rooted devices?
Helium Backup doesn't seem to work. I have played a game for long on my Mediapad, and I would like to copy that game to my phone. Unfortunately, my Mediapad is not rooted and losing all that game progress has become a nightmare. I have written to the app developer to provide some sort of backup using either Google Play Games or social media integration like Facebook/ Twitter, but haven't received any response.
3. How to force apps (esp. file managers & gallery apps) to use in-app media viewer without changing system default.
For example, I may use the stock gallery app as default for viewing media. But if I am using another gallery app or a file manager that is capable of viewing media files using its own media viewer, I would rather want it use it than open the default app. Is there a way to do it?
4. Replace stock file manager (a system app) with another app from Google Play Store or other sources. Is this possible?
I am not asking how to convert a user app into system app. I know that part. I tried replacing the apk file of the stock file manager with a 3rd party apk, even renamed it, but it didn't work.
5. Extract a system app from one device and install it on another device without root. Is this possible?
I have tried it, but apk installation fails. For example, Samsung Gallery app on OnePlus phones.
iOS
1. How to install .ipa (iPhone app) on an iPhone (not jail-broken) without a laptop (iTunes)?
2. Is it possible to have SFTP server for iPhone?
All Operating Systems
1. How to provide LAN only access for non-rooted devices as well as in Windows & iOS?
For rooted devices, we have apps like AFWall+ that can do it. But is there a way to do it for devices without root, as well as for Windows and iOS?
For non-rooted devices, we have apps like Netguard that support 'Allow LAN access' whilst blocking internet access.
Are there any alternatives and solutions for other platforms?
2. How safe is it to enter login credentials in an app to allow it access to network drives?
I use several apps (on various platforms) to connect to my laptop over SMB. This requires me to provide the app with my Windows Login Credentials, which is a Microsoft account. Am I risking my account by providing this info to the app? Is it safe to enter login credentials of cloud services in file manager apps?

Just bumping this thread as it seems to have been lost/ unnoticed.
@Ultramanoid can you answer some of these?

Can't help much, sorry. As to Android, some notes :
1. Never have used an OEM / Google's version of Android, or anything other than rooted single-user systems.
2. In addition to the previous answer, I'm not a gamer.
3. I usually don't ever set defaults with some rare exceptions, so I am always given a choice of what I want to use to handle a file. It may vary depending on many things; I may want to edit an SVG file as text, or view it as an image, for instance. There are applications / services that will intercept intents to allow you to do this sort of thing as well, but I can't recommend a specific one, never use them myself.
4. Possible, but will break Android as by now the system requires it as a file picker in many instances without recognizing alternatives and developers of most applications do expect it as well and their services will not work without it. Don't do it. With recent Android storage changes, including the scoped storage debacle, this is not a viable option anymore.
5. Depends, but not likely as a general rule, specially for OEM garbage, which relies on their own proprietary modifications of Android, their libraries, frameworks, et al. You'd have to carry those over to the destination too, which may not even be possible. Use OEM-independent and not Google Services reliant applications. ( Edit : you'll find some of those applications built to install on all devices here on XDA by single developers, "SONY camera for all devices" and that sort of thing, not recommended anyway, not well supported or long-lived experiments. )

Thanks very much. But I wish you answered the last 2 questions as well.
If time permits, would you be interested in telling us how you use your phone? I mean which device, which OS and what apps you use. I would like to give that a try (on a spare device) and see if it is possible for me to live without Google.

Didn't answer because it won't be helpful.
As to the 1st, I don't use LAN, and I don't keep data in any device or computer unless in use. External independent encrypted storage to be used wherever, whenever, independent of device, cables if needed.
As to the second, it's a matter of common sense, being informed of vulnerabilities and aware of reputation, and trust. Would you trust Chrome or Mozilla with data if you're online banking ? Seems reasonable -- but be aware of major vulnerabilities that may be going on. Would you trust an application released yesterday by a single developer for the same ? Probably not a good idea.
Finally, I doubt what I use and how I use it would be acceptable for you, or most people. In essence you could : Install latest firmware, wipe device, install latest security patched Lineage build for it, remove vendor / Lineage applications, get full root, remove anything you don't need or use which could have vulnerabilities; frameworks, libraries, binaries, etc ( Bluetooth, SMS, Android system-wide downloader, system-wide WebView, NFC, and on and on .. ), install your own binaries, fonts, hosts file, and applications where appropriate ( /bin /etc et al ), install Termux and all Linux packages required for your use, everything open source whenever possible, and stay away from any Google services / Play / applications with ANY trackers, analytics, data mining or even crash report capabilities; zero tolerance. Internet permission only for a secure web browser -- and terminal if / when needed. Half of what I do or use goes through terminal to be honest. In short, for me an Android device is a full Linux laptop replacement with added perks : Always on and on me, camera, GPS, pedometer, unlimited LTE data, and emergency calls for medics / police. ( Edit : And Japanese EEW alarm of course ! Only notification I use. We learned our lesson well in 2011. )

You can use ApkExport to extract any apk including system apks. I've transferred apks between other devices devices with it.
Never had need of doing that though with a system apk.
