Add minSdkVersion = ‘16’ to the android section in build.settings

[SUPER_TOKI]

@Lerg Thanks

[agramonte]

Or leave it at 15 and add this to the buildSettings.

manifestChildElements = 
        {
            -- Array of strings
            [[
            <uses-sdk tools:overrideLibrary="com.google.firebase.messaging" />
            ]]
        },

With this you can update, but did you succeed to launch the appli on a device?(I failed)

com.google.firebase.messaging

The ‘com.google.firebase.messaging’ needs min SDK 16. https://firebase.google.com/docs/cloud-messaging/android/client

[agramonte]

You can force a library to work with an SDK under the min with the code I specified. Usually on devices not supported the library will just fail but other times it will work. You just have to put some guard rails in case the library fails to load. I do it all the time for other libraries so I can support a larger range of devices especially on the Amazon store. Here is what mine looks like:

[[
    <uses-sdk tools:overrideLibrary="com.flurry.android.analytics.sdk, 
plugin.tapjoyInstall, 
com.tappx.sdk.android"/>
    ]]

I had this problem when building from external HDD, as soon I copied the app folder to my local disk, it worked like a charm with no errors
