android – INSTALL_FAILED_DUPLICATE_PERMISSION… C2D_MESSAGE

Posted by: admin March 10, 2020 Leave a comment

Questions:

I am using Google notifications in my app, and until now I have done below in the manifest:

<!-- GCM -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" /> <!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.WAKE_LOCK" /> <!-- Keeps the processor from sleeping when a message is received. --> 
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- This app has permission to register and receive data message. --> 

<!-- Creates a custom permission so only this app can receive its messages. NOTE: APP_PACKAGE.permission.C2D_MESSAGE -->   
<permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.myapp.permission.C2D_MESSAGE" />    
<!-- END GCM -->

It worked perfectly until I updated my Nexus 7 to Android 5.0.
Now when I try to install the app in this device with Eclipse, I get this error:

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

I don’t understand what is wrong? It was working perfectly until Android 5.0.
I know that I am using C2D_MESSAGE in two lines, permission and uses-permission but I have copied that code from the original Google GCM guide, so it must be fine.

How to&Answers:

I’ve found a solution that works for me.

In My Device (Nexus 7) Android 5.0. Lollipop I follow these steps.

After Uninstalling App You will find App Name under Apps List of the Downloaded tab.

  • Go to Settings
  • Apps
  • At the bottom of the list, you will find YourApp with a “NOT INSTALLED” Tag
  • Open
  • Click on OptionMenu and Select “Uninstall for all Users”

After these steps, I successfully install the new app and it’s running well.

Answer:

Remove

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

Run App…
Then Add the permisson again and Run App.

Ready!.

Answer:

I had the same problem with a custom signature permission on Android-21 and solved it by making sure I was doing a complete uninstall.

This is an edge case that occurs when:

  1. An application defines a custom permission using signature level security
  2. You attempt to update the installed app with a version signed with a different key
  3. The test device is running Android 21 or newer with support for multiple users

Command line example

Here is a command-line transcript that demonstrates the issue and how to solve it. At this point a debug version is installed and I am trying to install a production version signed with the release key:

# This fails because the debug version defines the custom permission signed with a different key:

[[email protected] svn-android-apps]# . androidbuildscripts/my-adb-install Example release
920 KB/s (2211982 bytes in 2.347s)
        pkg: /data/local/tmp/Example-release.apk
Failure [INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.example.android.example.PERMISSION_EXAMPLE_PLUGIN pkg=com.example.android.example]

# I use uninstall -k because apparently that is similar to uninstalling as a user
# by dragging the app out of the app tray:

[[email protected] svn-android-apps]# /android-sdk-linux/platform-tools/adb uninstall -k com.example.android.example
The -k option uninstalls the application while retaining the data/cache.
At the moment, there is no way to remove the remaining data.
You will have to reinstall the application with the same signature, and fully uninstall it.
If you truly wish to continue, execute 'adb shell pm uninstall -k com.example.android.example'

# Let's go ahead and do that:

[[email protected] svn-android-apps]# /android-sdk-linux/platform-tools/adb shell pm uninstall -k com.example.android.example
Success

# This fails again because the custom permission apparently is part of the data/cache
# that was not uninstalled:

[[email protected] svn-android-apps]# . androidbuildscripts/my-adb-install Example release
912 KB/s (2211982 bytes in 2.367s)
        pkg: /data/local/tmp/Example-release.apk
Failure [INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.example.android.example.PERMISSION_EXAMPLE_PLUGIN pkg=com.example.android.example]

# In spite of the warning above, simply doing a full uninstall at this point turned out to 
# work (for me):

[[email protected] svn-android-apps]# /android-sdk-linux/platform-tools/adb uninstall com.example.android.example
Success

# Release version now successfully installs:

[[email protected] svn-android-apps]# . androidbuildscripts/my-adb-install Example release
898 KB/s (2211982 bytes in 2.405s)
        pkg: /data/local/tmp/Example-release.apk
Success

[[email protected] svn-android-apps]# 

Eclipse example

Going in the opposite direction (trying to install a debug build from Eclipse when a release build is already installed), I get the following dialog:

Eclipse reinstall dialog

If you just answer yes at this point the install will succeed.

Device example

As pointed out in another answer, you can also go to an app info page in the device settings, click the overflow menu, and select “Uninstall for all users” to prevent this error.

Answer:

I’ve solved this without having to resort to uninstalling the alternate apk first (what a pain, right?). To successfully install both a debug and release version of an apk, simply use gradle’s built-in ${applicationId} placeholder within the AndroidManifest.xml to modify the permissions’ android:name values at compile time.

The build.gradle file snippet:

buildTypes {
    debug {
        applicationIdSuffix ".debug"
        ...
    }
}

The AndroidStudio.xml file snippet:

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

You can inspect the modified AndroidManifest.xml file within the apk using aapt l -a app-debug.apk to ensure the placeholder was properly applied. If you use various product flavors, I’m sure you can apply a variation of this method to suit your needs.

Answer:

Remove any “Hard Coded” reference of your package name, from your manifest file.

(This is best practice even if you don’t using productFlavors)

For example, if your manifest contains:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
<uses-permission android:name="com.yourpackage.name.permission.C2D_MESSAGE"/>

<permission
    android:name="com.yourpackage.name.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>
<permission
    android:name="com.yourpackage.name.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>

Changed it to:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>

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

Then, in your module gradle file, set your relevant applicationId:

signingConfigs {
    stage {
        storeFile file('keystore/stage.keystore')
        storePassword 'android'
        keyAlias 'androiddebugkey'
        keyPassword 'android'
    }
    production {
        storeFile file('keystore/playstore.keystore')
        storePassword store_password
        keyAlias key_alias
        keyPassword key_password
    }
}

productFlavors {
    staging {
        signingConfig signingConfigs.staging
        applicationId defaultConfig.applicationId + ".staging"
        versionName defaultConfig.versionName + "-staging"
    }

    production {
        signingConfig signingConfigs.production
    }
}

Answer:

try to uninstall the app with adb:

adb uninstall com.yourpackage

Answer:

While giving this error it will clearly mention the package name of the app because of which the permission was denied. And just uninstalling the application will not solve the problem. In order to solve problem we need to do the following step:

  1. Go to settings
  2. Go to app
  3. Go to downloaded app list
  4. You can see the uninstalled application in the list
  5. Click on the application, go to more option
  6. Click on uninstall for all users options

Problem solved 😀

Answer:

Installing an application in OS 5.0 i get this message:

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

There´s no duplicated packages, and we can solve this issue uninstalling manually the old application or using the adb:

adb uninstall com.yourpackage

Answer:

None of the above worked for me. My app was working fine in previous than Lollipop. But when I tested it on Lollipop the above error came up. It refused to install. I didn’t have any previous versions installed so all the above solutions are invalid in my case. But thanks to this SO solution now it is running fine. Just like most developers I followed Google’s misleading tutorial and I added the permissions by copy and paste like this:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="com.google.android.permission.C2D_MESSAGE" 
            android:protectionLevel="signature" />

This would work with older versions < Lollipop. So now I changed to:

<uses-permission android:name="com.mycompany.myappname.c2dm.permission.RECEIVE" />
<permission android:name="com.mycompany.myappname.permission.C2D_MESSAGE" 
            android:protectionLevel="signature" />

Answer:

CommonsWare is right, but in my opinion this is a (bug)poor way to say: “The apk installed on the device is signed with a different certificate then the new one you are trying to install”.

This is probably a new bug since in the past it used to ask whether or not to uninstall the app from the device due to wrong certificate.

The solution as painful as it may be would be to uninstall the app it manually.

Also what we’ve done for the sake of team development, we added the debug keystore to our repository, and point gradle to use it like so:

android {
    ...
    signingConfigs {
        debug {
            storeFile file("../certificates/debug.keystore")
        }
    }

    ...

    buildTypes {
        debug {
            signingConfig signingConfigs.debug
        }
    }

    ...
}

And now when passing devices between team members, we all use the same debug certificate, so there is no issue. 🙂

Answer:

In Android 5, check your settings -> apps. Instead of deleting for just the active user (since android 5 can have multiple users and my phone had a guest user) tap on the accessory button in the top right corner of the action/toolbar and choose “uninstall for all users”. It appears that in Android 5 when you just uninstall from launcher you only uninstall the app for the active user.

The app is still on the device.. This had me dazzled to since I was trying to install a release version, didn’t work so I thought ow right must be because I still have the debug version installed, uninstalled the app. But than still couldn’t install.. First clue was a record in the app list of the uninstalled app with the message next to it that it was uninstalled (image).

Uninstalled app still showing up in apps
Uninstalled for all users

Answer:

See this link it said that it will work when they are signed by the same key. The release key and the debug key are not the same.

So do it:

buildTypes {
        release {
            minifyEnabled true
            signingConfig signingConfigs.release//signing by the same key
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-android.txt'

        }
        debug {
            applicationIdSuffix ".debug"
            debuggable true
            signingConfig signingConfigs.release//signing by the same key
        }

    }

 signingConfigs {
        release {
            storeFile file("***\key_.jks")
            storePassword "key_***"
            keyAlias "key_***"
            keyPassword "key_"***"
        }


}

Answer:

replace below lines:

<permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.myapp.permission.C2D_MESSAGE" 
android:protectionLevel="signature" /> 

Answer:

In my case, I had several applications installed having the same domain name in the package name as follows.

com.mypackage.app1
com.mypackage.app2
com.mypackage.app3 
...

I had to uninstall all the apps having similar package names and reinstall them again in order to get rid of the problem.

To find all package names from the device I used the following.

adb shell pm list packages

Then I grabbed the packages that match my package name that I am looking for.

dumpsys | grep -A18 "Package \[com.mypackage\]"

Then uninstalled all the apps having that domain.

uninstall com.mypackage.app1
uninstall com.mypackage.app2
uninstall com.mypackage.app3
...

You can also uninstall the applications using the Settings app. Go to the Settings -> Apps -> Find the app -> Uninstall

Hope that helps someone having the same problem as me.

Answer:

Previously it used to say that an app with different signature is found on device. When installing from IDE it would also ask do you want to uninstall it?

But I think from Android 5.0 they have changed the reason for uninstallation. It does not happen if you are installing app with the same signature

Answer:

I encountered the same problem with a nexus 5 Android Lollipop 5.0.1:

Installation error: INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.android.** pkg=com.android.**

And in my case I couldn’t fix this problem uninstalling the app because it was an android app, but I had to change my app custom permissions name in manifest because they were the same as an android app, which I could not uninstall or do any change.

Hope this helps somebody!

Answer:

In my case I received following error

Installation error: INSTALL_FAILED_DUPLICATE_PERMISSION
perm=com.map.permission.MAPS_RECEIVE pkg=com.abc.Firstapp

When I was trying to install the app which have package name com.abc.Secondapp. Here point was that app with package name com.abc.Firstapp was already installed in my application.

I resolved this error by uninstalling the application with package name com.abc.Firstapp and then installing the application with package name com.abc.Secondapp

I hope this will help someone while testing.

Answer:

In your AndroidManifest.xml file, change your specially declared permissions’ names, for example:

<!-- Creates a custom permission so only this app can receive its messages. NOTE: APP_PACKAGE.permission.C2D_MESSAGE -->   
<permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.myapp.permission.C2D_MESSAGE" />    
<!-- END GCM -->

to this,

<!-- Creates a custom permission so only this app can receive its messages. NOTE: APP_PACKAGE.permission.C2D_MESSAGE -->   
<permission android:name="com.myapprocks.permission.C2D_MESSAGE"  android:protectionLevel="signature" />
<uses-permission android:name="com.myapprocks.permission.C2D_MESSAGE" />    
<!-- END GCM -->

com.myapprocks this part solves the conflict with your other app.

Answer:

In my case I was using a third party library (i.e. vendor) and the library comes with a sample app which I already had install on my device. So that sample app was now conflicting each time I try to install my own app implementing the library. So I just uninstalled the vendor’s sample app and it works afterwards.

Answer:

I uninstalled previous version. It worked for me.

Answer:

I restarted my phone after uninstalling the app and it worked

Answer:

If you have a different flavour of the app, try uninstalling that first. This helped me when I had the same issue.
