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:Userspei.gradlecachestransforms-1files-1.1DemoUtil-1.0.1.aar4a17a0a126acdb405884346818052524AndroidManifest.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。
