Hi, can someone explain me with apples how's applications like applock works ?
I am working on a Chinese android terminal, but I don't have the ROM to build a custome android.
is in android 4.4.2 and I need to make some controls with this hardware.
Based on the description it uses the accessibility features to implement this. The standard and safest way to create locked apps is with TaskLock: https://www.b4x.com/android/forum/threads/81765
