Answer 1

如果启用了multidex，则会发生此错误。要解决此错误，您必须进行一些更改。

1）在App根文件夹中创建文件名multidex.keep。

2）在该文件中写下com / amazon / android / Kiwi.class。

3）打开app的build.gradle文件，在android标签中写下代码。

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

4）打开app build.gradle文件并在android标签内写

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()
    }
}

}
