Why Application ask Permission ?

Every Apps install in Android phone ask some permission in Phone from the user, that required for proper work flow of an application.

There are around 324 permission in android phone.

Types of Permission

• Normal Permission
• Signature Permission
• Dangerous permissions
• Special permissions

Normal permissions

Normal permissions cover areas where your app needs to access data or resources outside the app’s sandbox, but where there’s very little risk to the user’s privacy or the operation of other apps. For example, permission to set the time zone is a normal permission.

Signature permissions

The system grants these app permissions at install time, but only when the app that attempts to use a permission is signed by the same certificate as the app that defines the permission.

Dangerous permissions

Dangerous permissions cover areas where the app wants data or resources that involve the user’s private information, or could potentially affect the user’s stored data or the operation of other apps. For example, the ability to read the user’s contacts is a dangerous permission. If an app declares that it needs a dangerous permission, the user has to explicitly grant the permission to the app. Until the user approves the permission, your app cannot provide functionality that depends on that permission.

To use a dangerous permission, your app must prompt the user to grant permission at runtime. For more details about how the user is prompted.

Special permissions

There are a couple of permissions that don’t behave like normal and dangerous permissions. SYSTEM_ALERT_WINDOW and WRITE_SETTINGS are particularly sensitive, so most apps should not use them. If an app needs one of these permissions, it must declare the permission in the manifest, and send an intent requesting the user’s authorisation. The system responds to the intent by showing a detailed management screen to the user.

General Permission ask while Installing

there is reason behind the permission which is required for application but if application permission is not suitable with application then application can be a threat. Example a simple calculator app asking permission of contacts (which is not be suitable thing) combination of calculator with contacts is not good application avoid to install or if you already install the uninstall it.
