Network Master 1.1.1 requires the following permissions:

Allows an app to access approximate location. Alternatively, you might want ACCESS_FINE_LOCATION.

Allows applications to access information about networks.

Allows applications to access information about Wi-Fi networks.

Allows applications to change network connectivity state.

Allows applications to enter Wi-Fi Multicast mode.

Allows applications to change Wi-Fi connectivity state.

Allows an application to clear the caches of all installed applications on the device.

Allows an application to expand or collapse the status bar.

Allows an application to find out the space used by any package.

Allows an application to install a shortcut in Launcher.

Allows applications to open network sockets.

Allows an application to call killBackgroundProcesses(String).

Allows an application to collect component usage statistics

Allows an application to read from external storage.

Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.

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 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.

Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.

Allows an application to write to external storage.
