Amazon rep says that I am using ADM (Amazon Device Messaging) in my app but I don't and my manifest has no permissions for ADM (or even GCM for that matter).

Solution

This error is happening if you have multidex enabled. For resolving this error you will have to do some changes.

1) Create a file name multidex.keep in App root folder.

2) Write com/amazon/android/Kiwi.class in that file.

3) Open app's build.gradle file and write below code in android tag.

dexOptions {
    incremental true
    javaMaxHeapSize "4g"
    preDexLibraries = false
    additionalParameters = ["--set-max-idx-number=55000"] // default 60000
}

4) Open app build.gradle file and inside android tag write

afterEvaluate {
if (!android.applicationVariants.matching { it.flavorName == 'mobile' }.isEmpty()) {
    tasks.matching {
        it.name.startsWith('dex')
    }.each { dx ->
        if (dx.additionalParameters == null) {
            dx.additionalParameters = []
        }
        dx.additionalParameters += '--multi-dex' // enable multidex
        dx.additionalParameters += "--main-dex-list=$projectDir/multidex.keep".toString()
    }
}

}
