Permission is only granted to system app

In Eclipse:

Window -> Preferences -> Android -> Lint Error Checking.

In the list find an entry with ID = ProtectedPermission. Set the Severity to something lower than Error. This way you can still compile the project using Eclipse.

In Android Studio:

File -> Settings -> Editor -> Inspections

Under Android Lint, locate Using system app permission. Either uncheck the checkbox or choose a Severity lower than Error.

To ignore this error for one instance only, add the tools:ignore="ProtectedPermissions" attribute to your permission declaration. Here is an example:

<uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE"
    tools:ignore="ProtectedPermissions" />

You have to add tools namespace in the manifest root element

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
