Android. How to share files directly with WI-FI


Bluetooth can be useful for sharing files, however, it is pretty slow and not all the laptops and portable devices support it. Here you will learn how to share files via WIFI to any device, and the best is that you won't need to carry a USB cable.

There are many apps in the Play Store that does the trick, but contains adds and are not open source , such as Wi-Fi Direct or Superbeam.

I hope you find this method more transparent and simple.

First you will need to enable the Portable Wi-Fi Hostpot in your cellphone, there you will create a Wi-Fi network with a custom name and password.

For more details visit the following link:

Then connect to that Wi-Fi network with the other device. In this way both devices are (almost) ready to share files.

Finally install and run the FTP server application available in both Play Store and F-droid. It will show you an ip like ftp://192.168.0.1:2121 , type that ip in a web browser from your laptop (the device connected to the Hotspot) , and there you can browse and download the files of your Android device.

Do not forget to disable the Hotspot in the same way that Data mobile is disabled (in the android settings drop-down menu)

Note: You can skip the first step if both devices are connected in the same local network, in that case you only need to use the FTP server application. However, notice that the transfer speed will be slower.


Automatic shutdown in Android.


I used to recommend to automatic enable the Airplane mode at night, but to tell you the truth that application started to fail. It is a pity that the Android phone cannot automatically wake up like most of the modern computers.

But at least I want a quiet sleep, so it isn't that bad relay on a traditional Alarm Clock while the Cellphone do automatically shutdown in night.

There is an application in the Play Store to automatically shutdown the phone, but you know, I foremost recommend you to use Linage OS instead Android, second to uninstall the Play Store, and finally to only use Open Source Software (F-droid).

So you will be able to do this with Free Software:

Requeriments:

  • Rooted phone
  • Su installed
  • Busybox (Vi)
  • A Terminal Emulator (Termux recommended)

1. In the F-droid store install Crond.

2. Open Crond

3. Open a terminal and execute su

4. Execute vi /data/crontab and add:

0 21 * * * poweroff -n -f

Where 0 are the minutes, and 21 the hour, and the following asterisk are wildcards, you can learn more about how to use cron and crontab for further customización

Crond is pretty powerful if you know about the Linux command line and/or programming.


The KISS interface


This was the appearance of my cellphone after I reset it:

I had installed KISS, and also I had deleted the Linage OS launcher (Trebuchet) , finally I made KISS a system app, thus, it became part of my custom ROM and persisted the reset.

Note: First install KISS because deleting Trebuchet is very likely to ruin your system

I did all that using Link2SD, I uninstalled that app after using it because it have ruined my system 3 times (because I love to uninstall everything I don't like)

And I recommend you a lot the KISS launcher; I'm feed up with widgets and screens, I just keep my cellphone simple, this launcher is really slim and fast. And it will help you to get the things done.
That's all.


Reseted my cellphone


Today I reset my cell, and I found out that it is not rooted anymore. The rooting was an additional steep after I installed my custom ROM (Linage OS), I only have to enable the developer settings in order to re-enable root.
In this new fresh start I avoided to provide my Google account since it is not necessary nor desirable as a matter of privacy. Following are the apps I installed sorted by time.

  1. F-droid: This is the first app that I installed because it allows to install open source apps easily, for this I enabled the installation from unknown origins and downloaded the APK.
  2. OpenVPN for Android
  3. I installed this application from F-droid, it allow me to use the OpenVPN protocol for using VPN since VPN is a must in the post-Snowden age in order to maintain the privacy, I suggested you to use Tor as root for all applications, however, it uses a lot of battery and using VPN is more practical and it doesn't requires root.
  4. Yalp Store: I installed this application from F-droid, it allows to install applications from the Google Play anonymously (Remember that I permanently deleted Google Play).
  5. Firefox Focus: I installed it from Yalp Store because I didn't find it in F-droid, it is from Mozilla, so it's safe to install, this web browser is an ever incognito mode browser.
  6. Delta Chat: I installed this application for receiving my emails of [email protected]
  7. 7 Zipper: I installed with Yalp Store, this application is not free and includes advertisement, however is the best application for compressing and managing compressed files.
  8. Text Edit: This a very simple text editor, but it's perfect, I only need a text editor for editing text and that's all.

Note: I ruined my cellphone by freezing and using many applications requiring root, even if now my cellphone consumes more energy I will only keep a minimal set of applications. My cellphone was ruined after I installed Google Services and made it a system app using Link2SD
