Tensorflow Lite 编译demo时报错 ERROR: missing input file

Tensorflow Lite 编译demo时报错，这些都是坑

错误一
ERROR: missing input file ‘@androidsdk//:build-tools/27.0.2/aapt’

ERROR:/home/xx/.cache/bazel/_bazel_di/0c60e5cf6a2b1bd6f8f12b5ea9e6433c/external/androidsdk/com.android.support/BUILD:3902:1: @androidsdk//com.android.support:support-core-utils-25.2.0: missing input file ‘@androidsdk//:build-tools/27.0.2/aapt’
Target //tensorflow/contrib/lite/java/demo/app/src/main:TfLiteCameraDemo failed to build

解决方案：
修改或者拷贝build-tools里面的文件夹名称android-8.1.0为27.0.2（视使用的版本而定）

错误二

解决方案
platforms明明有api level为23的sdk,但是还是会出现这种错误，将platforms中文件夹名称android-6.0 改为 android-23（视sdk版本而定，android 6.0对应 api level 23）
