使用 kotlin 在 android studio 中出错

Question

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.google.firebase:firebase-auth:19.2.0] /home/shubham/.gradle/caches/transforms-2/files-2.1/782dd1b43e0016afc3d7d0a4252da9e3/firebase-auth-19.2.0/AndroidManifest.xml as the library might be using APIs not available in 15
    Suggestion: use a compatible library with a minSdk of at most 15,
        or increase this project's minSdk version to at least 16,
        or use tools:overrideLibrary="com.google.firebase.auth" to force usage (may lead to runtime failures)

Answer 1

In your application modules' build.gradle ; change minSdkVersion to at least 16.

Like so:

android {

    defaultConfig {
        applicationId "YOUR_APPLICATION_ID"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0.0"
    }

Answer 2

com.google.firebase.auth min 16 , 你的项目 min 是 15, 你应该把 minSdkVersion 改成 16. 解决它的坏方法是你的mainfest，它可以运行但运行时可能会出错
