Your inclusion of permissions in the manifest is an explicit statement to the user that your app will use these permissions and the user is basing their decision on your claim. One of the most significant issues with this point is more user acceptance driven than security driven. The more permissions your app requests, the more likely a user (especially a securityconscious one) is to reject it at installation time. ). Because you presumably want as many users as possible to install your app, you should ask for just the permissions you need and no more.
A Broadcast Receiver is a type of component that listens for system messages called Intents. An Intent can be thought of as a request for a certain action to take place. Apps can create Intents and either send them directly to a specific component (usually an Activity or a Service) or broadcast them system-wide to all apps that are running. A Broadcast Receiver is a component that can receive these systemwide broadcasts and act upon them; it can choose to listen for all broadcast Intents or set up filters so that it receives only Intents for the specific actions it cares about (and would, presumably, take action upon).
Chapter 3 discusses the Android permission model and how to use it. 24 | Chapter 2: Android Architecture CHAPTER 3 Application Permissions As we discussed in Chapter 2, Android takes a different approach to running apps than traditional, desktop-based systems. On traditional systems, apps run under the account of the user who started them, and run with whatever permissions were granted to that user account. There are no per-app separation mechanisms. In addition, all apps running under that same user account have the same level of access to system APIs and other services provided by the underlying environment; both a document viewer and a VoIP application have the same level of access to the networking system because they run under the same UID by default.
