前言

今天在写demo的时候，引用了一个库，我自己的studio是sdk25，而引用的库的版本是sdk28，studio3.3的，版本较高，于是出现“error: failed linking references.”

解决办法

这里我首先将我app_module对应的

compileSdkVersion 25

修改为

compileSdkVersion 28

，然后下面引用的

 implementation  'com.android.support:appcompat-v7:25.3.1' 

报错，按提示修改为

implementation  'com.android.support:appcompat-v7:28.0.0'

运行提示：

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 19 declared in library [com.github.ShaoqiangPei:DemoUtil:1.0.1] C:\Users\pei\.gradle\caches\transforms-1\files-1.1\DemoUtil-1.0.1.aar\4a17a0a126acdb405884346818052524\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 19,
        or use tools:overrideLibrary="com.lib" to force usage (may lead to runtime failures)

ok,按提示将 app_module中的 minSdkVersion 15 改为 minSdkVersion 19，编译，运行，就可以了。

看来，低的sdk配置的项目在引用高sdk配置的第三方库，还是存在兼容问题啊。
