Y!乗換案内 7.14.2 requires the following permissions:

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

Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.

Allows applications to access information about networks.

Allows an application to install a shortcut in Launcher.

Allows applications to open network sockets.

Allows an application to read from external storage.

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 record audio.

Allows access to the vibrator.

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

Allows an application to write to external storage.
