But I did not understand when and why should we use permissions tag in Manifest file and what is its difference from uses-permission.

推荐答案

引用文档:

要实施自己的权限，您可以首先必须在您的网站中声明它们 AndroidManifest.xml 使用一个或多个< permission> 标签.例如，想要控制谁可以开始其活动之一的应用程序可以声明此操作的权限，如下所示:

To enforce your own permissions, you must first declare them in your AndroidManifest.xml using one or more <permission> tags. For example, an application that wants to control who can start one of its activities could declare a permission for this operation as follows:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.me.app.myapp" >

    <permission android:name="com.me.app.myapp.permission.DEADLY_ACTIVITY"
        android:label="@string/permlab_deadlyActivity"
        android:description="@string/permdesc_deadlyActivity"
        android:permissionGroup="android.permission-group.COST_MONEY"
        android:protectionLevel="dangerous" />

</manifest>

因此，< uses-permission> 是在您的应用程序正在寻求用户使用某些功能的许可时，而< permission> 是在您的应用程序需要时其他应用程序以征求用户的许可以使用您的某些功能.

Hence, <uses-permission> is when your application is seeking the user's permission to use some feature, while <permission> is when your application is requiring other apps to seek the user's permission to use some feature of yours.
