Required to be able to access the camera device.

Allows an application to modify the current configuration, such as locale.

Allows applications to change network connectivity state.

Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.

Allows an application to change the Z-order of tasks.

Allows an application to broadcast an Intent to set an alarm for the user.

Allows an application to open, close, or disable the status bar and its icons.

Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.

This permission is no longer supported.

Allows applications to write the apn settings.
