我正在尝试为React Native应用创建签名的APK。调试应用程序运行正常。 我正在按照react native guide创建签名的APK。
我已将密钥库添加到应用程序并设置gradle变量，但是无法进行签名的apk。
以下是assembleRelease构建的错误
./gradlew assembleRelease --stacktrace
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to /home/anuragdhunna/Android/Sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

此外，我心中还有一个问题，为什么我面对NDK警告而不使用ndk，我有SDK平台工具。我该如何删除NDK警告，任何猜测？
答案 0 :(得分：0)
如果./gradlew clean无法解决问题，则可以尝试以下操作：
ReactNativeApp/android/build目录重命名为old.build ./gradlew clean ./gradlew assembleRelease 答案 1 :(得分：0)
SimpleLineIcons.ttf的错误与NDK警告无关。
