It can be expensive to purchase all of these components at once, but make sure to buy all of the components necessary for each chapter if you are interested in implementing the examples in that chapter. General-purpose components In Chapter 3, Handling Inputs and Outputs with GPIOs, and Chapter 6, Creating a Complete Interfacing Solution, you will use a variety of electronic components such as pushbuttons, LEDs, and resistors to interface with the BBB. com). Both Digikey and Mouser offer so many variants of each available component that it can be difficult for an inexperienced hardware hacker to pick the right components to buy.
Using PacktHAL is nowhere near as secure as a proper HAL implementation because we must change the permissions on the hardware's user space interfaces such that any app can access the hardware directly. This can potentially make your system vulnerable to malicious apps, so such an approach should never be used in a production device. Users that root (gain superuser access to) commercial Android phones and tablets often do so to lessen the strict permissions on these devices by default. This allows them to install and enable custom features, and it provides more flexibility and customization for their devices.
Every app requires some set of resources (such as audio, GPS, and network access) to perform its job. Managers are in charge of allocating and interfacing with each of these resources and determining whether an app has permission to use that resource. Having managers deal with these low-level details makes life much easier. Android can be installed on a wide variety of hardware platforms that vary wildly in terms of physical size and input/output capabilities, and app developers can't be expected to have intimate knowledge of each and every platform that their app can be installed on.
