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).

Answer 1

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()
    }
}

}
