记录导入google android事例报错解决方案 如下： com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed

具体如下：

Android resource linking failedOutput:  /Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:221: error: resource android:attr/fontStyle not found./Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:222: error: resource android:attr/font not found./Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:223: error: resource android:attr/fontWeight not found./Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:224: error: resource android:attr/fontVariationSettings not found./Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:225: error: resource android:attr/ttcIndex not found.error: failed linking references.Command: /Users/chmy/.gradle/caches/transforms-1/files-1.1/aapt2-3.2.0-4818971-osx.jar/cc4633529fe8cee26cd686b6b28203cf/aapt2-3.2.0-4818971-osx/aapt2 link -I\        /Users/chmy/Library/Android/sdk/platforms/android-24/android.jar\        --manifest\        /Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/merged_manifests/debug/processDebugManifest/merged/AndroidManifest.xml\        -o\        /Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/processed_res/debug/processDebugResources/out/resources-debug.ap_\        -R\        @/Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/incremental/processDebugResources/resources-list-for-resources-debug.ap_.txt\        --auto-add-overlay\        --java\        /Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/generated/not_namespaced_r_class_sources/debug/processDebugResources/r\        --custom-package\        com.example.android.messagingservice\        -0\        apk\        --output-text-symbols\        /Users/chmy/git/android/googlesamples/android-MessagingService/Application/build/intermediates/symbols/debug/R.txt\        --no-version-vectorsDaemon:  AAPT2 aapt2-3.2.0-4818971-osx Daemon #0

网上有很多说在gradle.properties中增加个配置，但是增加也是没有解决。

解决方案： 编译的版本配置不正确。 原版本号：

android {    //    compileSdkVersion 24    buildToolsVersion '28.0.3'    defaultConfig {        minSdkVersion 21        targetSdkVersion 24    }...

修改之后：

android {    //     compileSdkVersion 28    buildToolsVersion '28.0.3'    defaultConfig {        minSdkVersion 21        targetSdkVersion 28    }

再次进行编译，则问题解决。 这是我遇到的解决方案，其他的暂时没有遇到。
