[Tasker] Extreme battery saving profile

The battery life of an android phone is not impressive and we got used to charge our phones every day. Nevertheless it can happen that one finds himself in a situation with no charger in reach and no battery left. This profile will help you to avoid this situation. This profile will fire when your battery level will drop under 8% automatically. It is a drastic step, think twice before using it.
This task will:
  • Put your phone into flight mode (I warned you, drastical steps ;)
  • Set the display brightness to deep Darth Vader like darkness
Yes, you won't be reachable. But you can switch off the flight mode whenever you wish and still send or receive the important messages you would miss otherwise. In my opinion it's better then finding your phone completely drained without any options left. The phone should last minimum another hour in this mode.
You will need:

This is what my profile looks like:
Profile: Extreme battery save (28)
     State: Battery Level [ From:0 To:8 ]
Enter: Extreme battery save (3)
     A1: Auto Brightness [ Set:Off ]
     A2: Display Brightness [ Level:0 Disable Safeguard:Off Ignore Current Level:Off Immediate Effect:On ]
     A3: Load App [ App:Screen Filter Data: Exclude From Recent Apps:Off ]
     A4: Airplane Mode [ Set:On ]
     A5: Notify LED [ Title:Battery low Text:Battery under %BATT percent!
          Will switch to battery saving mode. Icon:ipack:crystalhd:cache Number:%BATT Colour:Red Rate:1000 Priority:3 ]
     A6: Zoom Visibility [ Element:Extreme battery save.w / StateON Set:On ]

The normal mode profile could look like this and be activated when a power source is connected:
Profile: Power source connected (11)
     State: Power [ Source:Any ]
Enter: Energy save (17)
     B1: Notify Cancel [ Title:Battery low Warn Not Exist:Off ]
     B2: Airplane Mode [ Set:Off ]
     B3: Display Brightness [ Level:128 Disable Safeguard:Off Ignore Current Level:Off Immediate Effect:On ]
     B4: Auto Brightness [ Set:On ]
     B5: Zoom Visibility [ Element:Extreme battery save.w / StateON Set:Off ]
     B6: Run Shell [ Command:am force-stop com.haxor Timeout (Seconds):0 Use Root:On Store Output In: Store Errors In: Store Result In: ]

The line B6 kills the screen filter app if it is running and will do nothing if it's not running. To create it go to Script -> Run shell -> and enter the command am force-stop com.haxor :) The downside of this powerful command is, it needs root. Maybe you can get the same result by setting up the action App -> Kill App -> Screen filter. No guarantee on this.
You should have problems with creating lines A6 and B5 yet, as there is no Zoom widget yet. So... stay with me after the commercial break....

...your ads here...


Off
Again there is a widget to switch this on and off from the home screen dynamically.
My widget looks like this, you will need two icon packs and the app Zoom to get the same result:

More information on Zoom and how to setup cool widgets can be found on google and here.
Import my Zoom profile by saving the following file as "Extreme_battery_save.w.ztl.xml" under sdcard/Zoom/templates. Then open Zoom and press menu key -> Browse Templates -> Import Directory -> Extreme_battery_save.w.ztl.xml. Now create this Zoom 1x1 widget on your home screen.

[Tasker] How to force a loud alarm on SMS / emergency SMS

If an SMS which contains (notice the "*") the text WAKEUP! comes in, your phone will alert you - no matter what. It's pretty hard to turn this alert off too ^^", you will have to stop the task.

The profile description:
Profile: Emergency SMS (72)
 Event: Received Text [ Type:Any Sender:* Content:*WAKEUP!* ]
Enter: Alarm! (71)
 Run Both Together
 A1: Play Ringtone [ Type:Alarm Sound:Ticktac alarm Stream:4 ]

Please notice the type when selecting the ringtone, the stream must be set to Alarm. Here the same as a profile to import directly:

[Tasker] Take pictures of intruders and send them per mail silently

This script will detect when someone enters the wrong unlock code or swipes the wrong pattern and sends a picture to an E-Mail address in the background, silently.
For some reason it works better with long patterns and even better with long pin codes. I don't know why. If you know it, let me know :)

Let's start, please get:
  • Tasker
  • Secure Settings (To setup a profile in Tasker which detects wrong unlock codes)
  • Python for Android (To run python code)
  • SL4A (To run the python script from Tasker)
  • The python script "SendEmailA.py" from the Tasker Wiki. (Send an E-Mails silently)
  • GoogleMail address
Open the Python for Android application, make sure it is not Python3. Press install button to install the Python runtime environment.
Open SL4A and run the "hello_world.py" script by tapping on it and selecting the leftmost terminal icon. Congratulations, you successfully installed Python and can run Python scripts from Tasker!

Here is my "SendEmailA.py" script. It has a small modification to the original file which is marked in red.

Save this file to your internal SDCard in the SL4A scripts folder (f.e. SDCard\SL4A\Scripts).

The preparation is done, lets go to Tasker. Create a new profile name it "Security Glitch" or something less obvious. Goto State -> Plugin -> Secure Settings. Click on the Edit field near configuration and select the condition "Failed Login Attempts". Type in a low number, like two. Enable "Device Admin". Read and accept the dialog. Click on save in the lower left corner. Hit the back button and create a new Task, name it "Cheeeese" or similar.
Here is my Cheeeese task:
Cheeeeese (45)

Please make sure the folder "/sdcard/DCIM/Tasker/" exists and you have the right information filled in in the purple fields. You can put a file named .nomedia into the DCIM/Tasker/ folder to make sure, it is not displayed in the gallery.
If you don't know how to setup a specific action, please google it. Line A16 is very important. To create this line goto Script -> RunSL4A Script -> in the name field select the "SendEmailA.py" file. Don't check the Terminal field, but fill in the Pass Variable field with %EMAIL_USER,%mailp,%EMAIL_TO,%EMAIL_ATTACH. The order is important. Check continue task after error.

You can delete the bright blue lines after running the Task once successfully. Please note, that your Google Mail password is stored as a global variable in Tasker Base64 encoded - but it is not a safe encryption! If you have suggestions on how to store the password encrypted n Tasker, please tell me!

Run the task a few time to check if your device vibrates twice (short vibrate at the beginning and a long vibrate at the end. Check your myemailtosendto@domain.com mails, don't forget to look into the spam folder. If you received a picture exit Tasker, lock your device, count to ten and check by entering the wrong unlock code/pattern a few time. Maybe you can make the profile run with a higher priority, not necessary. If everything went well and you received the beautiful pictures of yourself delete the bright blue lines.
Uninformatively there is an android limitation which will show the SL4A icon for a second in the notification bar when the email is send... I tried to make python run without SL4A, but was not successful yet. A workaround could be to make the icon transparent...

I wrote this down pretty fast, please forgive me if something is unclear. I will refresh this post soon.
