Using Permissions

---

A basic Android application has no permissions associated with it by default, meaning it cannot do anything that would adversely impact the user experience or any data on the device. To make use of protected features of the device, you must include one or more <uses-permission> tags in your app manifest.
For example, an application that needs to monitor incoming SMS messages would specify:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.android.app.myapp" >
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    ...</manifest>
