[Q] Prevent changing of keyboard topic

Is there a way I can prevent a user from changing input method?

I want to build an app with some device administration features. One important feature will be the ability to prevent a change of input method.

Is there an api to prevent a user from changing input methods in the settings? Maybe some other device administration apps that you know of that do it?

[Q] How to put a password on app to prevent opening? (Android L) topic

Hi all,

I was using Lockdown, a perfect app for locking down apps in drawer with a PIN. I'm on Android L now though, and that app works one time the other don't, so it's not that safe anymore.
What app can I use to lock and prevent opening of other app?

HOWTO: Prevent Oppo driver CD from mounting topic

It annoys the hell out of me when I plug the phone in by USB and it mounts a pointless virtual CD drive with the drivers on. You can disable it on your own PC, but when you plug in to someone else's having it pop up and autoplay the driver installer is often unwelcome. There's probably a better way to do this, but it works for me :)

Steps:

1) Have root, a working ADB, and backups (nandroid)
2) adb shell

Code:

---

su
mount -o remount,rw /system
cd /system/etc
cp init.qcom.post_boot.sh init.qcom.post_boot.sh.bak
echo setprop sys.usb.config mtp,adb >> init.qcom.post_boot.sh

---

If you need to get the drivers urgently, then from adb or a shell:

Code:

---

setprop sys.usb.config mtp,mass_storage,adb
