英文:
how to support app to run on all devices that contain finger print feature
问题
您好，希望您一切顺利。我正在开发一个包含指纹识别功能的应用程序，在其中的某一点上，我启用了一个指纹识别 SDK，其最低 minSdkVersion 为 23。我希望能够在所有设备上运行此应用程序，但当我将 minSdkVersion 更改为 16 时，它无法运行。下面是显示的错误信息：
清单合并失败：uses-sdk:minSdkVersion 16 不能小于库中声明的版本 23 [me.aflak.libraries:fingerprint:2.5.3] C:\Users\Zahid Iqbal\.gradle\caches\transforms-2\files-2.1清单合并失败：uses-sdk:minSdkVersion 16 不能小于库中声明的版本 23 [me.aflak.libraries:fingerprint:2.5.3] C:\Users\Zahid Iqbal\.gradle\caches\transforms-2\files-2.1\0f64be97807f594934240311bd0e96bb\jetified-fingerprint-2.5.3\AndroidManifest.xml，因为该库可能使用 16 中不可用的 API。
建议：使用最多具有 minSdk 版本 16 的兼容库，
或将此项目的 minSdk 版本增加至少为 23，
或使用 tools:overrideLibrary="me.aflak.libraries" 强制使用（可能导致运行时失败）。

下面是 jetified-fingerprint 的清单：

package="me.aflak.libraries"
android:versionCode="37"
android:versionName="2.5.3">
<uses-sdk
android:minSdkVersion="23"
android:targetSdkVersion="27" />
<uses-permission android:name="android.permission.USE_FINGERPRINT" />
</manifest>

hi sir hope you are right. I am working on app that contain fingerprint feature in it at one point and which fingerprint sdk i enabled its min minSdkVersion is 23 and i want to allow this app to run on all devices when i changed minSdkVersion to 16 then its not running. here is the error mesage below which it shows
Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 23 declared in library [me.aflak.libraries:fingerprint:2.5.3] C:\Users\Zahid Iqbal\.gradle\caches\transforms-2\files-2.1Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 23 declared in library [me.aflak.libraries:fingerprint:2.5.3] C:\Users\Zahid Iqbal\.gradle\caches\transforms-2\files-2.1\0f64be97807f594934240311bd0e96bb\jetified-fingerprint-2.5.3\AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 23,
or use tools:overrideLibrary="me.aflak.libraries" to force usage (may lead to runtime failures)

你不能在最低的 SDK 版本高于你自己的最低 SDK 版本时使用库。Omar Aflak（https://github.com/OmarAflak/Fingerprint）在他的库中使用了 minSDK 23。你需要提高你的最低版本或者使用另一个库。
我刚刚在这篇文章中读到 https://jaxenter.de/fingerprint-sensor-in-android-das-muessen-entwickler-wissen-36481 （抱歉，这是德语），指纹支持是在 SDK 23（Marshmallow Android）中添加的。所以你甚至不需要支持更早的版本。
也许这可以帮助你进一步 https://stackoverflow.com/questions/6109980/run-app-with-higher-sdk-on-lower-sdk
英文:
You can't use a library with minimum Sdk version above your own minimum Sdk version. Omar Aflak (https://github.com/OmarAflak/Fingerprint) uses minSDK 23 in his library. You have to raise your minimum version or use another library.
I just read in this article https://jaxenter.de/fingerprint-sensor-in-android-das-muessen-entwickler-wissen-36481 (sorry, it's german) that fingerprint support was added in SDK 23 (Marshmallow Android). So you do not even need to support older versions.
