There's a little known feature in the M developer preview that wasn't announced in the Keynote, probably because of this:
It's not shown in user builds, so we have to do some messing. You'll either need root or a custom recovery to do this, but as we don't have proper root on M yet, here's how you do it with TWRP, a USB cable, and a PC with ADB:
INSTRUCTIONS
1. Boot your device into recovery
2. Mount your system by going to Mounts > Tick System
3. On your PC open a command line, somewhere like your desktop is useful
4. Type the following command:
1. Boot your device into recovery
2. Mount your system by going to Mounts > Tick System
3. On your PC open a command line, somewhere like your desktop is useful
4. Type the following command:
Code:
adb pull /system/build.prop
6. Find the "ro.build.type" line
7. Change the text after = to "userdebug" from "user"
BONUS: If you want a nicer DPI here, change the line "ro.sf.lcd_density" to your preferred DPI
8. Save the file
9. Go back to the command line and enter the following command:
Code:
adb push build.prop /system/
Code:
adb shell
Code:
cd system chmod 644 build.prop
13. When the device has booted, go to the developer options
14. Scroll down to the bottom of the "Drawing" category
15. Enable multi-window and have some fun!
