In this blog,
I have shown you when to come this issue and how to resolve it.

When to come

This is issue commonly comes in <5.1 version. Means Lollipop or greater version. And if you use the same permission in manifest then error shows,

INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.app.permission.C2D_MESSAGE pkg=com.app

How to resolve

We will give the example of GCM permission,

You can use the ${applicationId} on the place of packageName in AndroidManifest.xml file.

Replace

<permission
    android:name="com.demoapp.webkul.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>

<uses-permission android:name="com.demoapp.webkul.permission.C2D_MESSAGE"/>

<permission

android:name="com.demoapp.webkul.permission.C2D_MESSAGE"

android:protectionLevel="signature"/>

<uses-permission android:name="com.demoapp.webkul.permission.C2D_MESSAGE"/>

<permission
    android:name="${applicationId}.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>

<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>

<permission

android:name="${applicationId}.permission.C2D_MESSAGE"

android:protectionLevel="signature"/>

<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>

And in receiver’s intent-filter:

replace

<category android:name="com.demoapp.webkul"/>

1	<category android:name="com.demoapp.webkul"/>

<category android:name="${applicationId}"/>

1	<category android:name="${applicationId}"/>

And DUPLICATE_PERMISSION issue will be resolved.

Tag attribute name has invalid character ‘$’

Tag is to filter incoming GCM notifications based on your package name. ‘$’ should be valid here.
Maybe you have written something wrong in your manifest file. If you share your code snippet then we may solve your problem.
Thanks.
