Question

我试图使Apk成为本机反应，但是它什么也没给我。 Apk文件中的发布文件为空，并且Gradlew捆绑包发布完成后，它说

    Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4.1/userguide/command_line_interface.html#sec:command_line_warnings

我找不到解决方法

Answer 1

在2020年，如果您遇到同样的问题，Powershell的建议对我有所帮助。

。\ emulator.exe -avd“ MyAvd”

在SDK模拟器所在的目录（C：\ Users \ AppData \ Local \ Android \ Sdk \ emulator）中运行上述命令，然后您可能会收到一些如下所示的说明：

您的模拟器已过时，请通过启动Android Studio进行更新：

启动Android Studio
选择菜单“工具> Android> SDK管理器”
点击“ SDK工具”标签
选中“ Android Emulator”复选框
点击“确定”

此链接也将很有帮助。 link

Answer 2

您是否尝试过运行./gradlew bundleRelease --warning-mode all？

它将为您提供有关不兼容内容的更多信息。

Answer 3

这在React Native项目中发生在我身上。这是在Windows（10个64位）中修复它的分步操作：

1）在没有Android Studio（https://windowsloop.com/launch-avd-manager-without-android-studio/）的情况下运行avd

2）在项目gradle wrapper中运行的另一个控制台中（您必须已安装Gradle 5.4.1（https://gradle.org/install/））

3）然后移至cd android，在此处运行gradlew clean

4）移至根cd..并运行react-native start

5）在项目react-native run-android中运行的另一个控制台中

Answer 4

转到项目文件运行gradle wrapper。
然后移至cd android，在这里运行gradle clean。
移动到根目录“ cd ..”并运行react-native start。
在项目react-native run-android中运行的另一个控制台中

您的项目将开始运行！

Answer 5

要解决此问题，您需要找到此文件（gradle-wrapper.properties）。该文件位于项目文件夹中的d路径（android / gradle / wrapper）中。...打开文件并更改此行< / p>

distributionUrl=https://services.gradle.org/distributions/gradle-5.5-all.zip

对此：

distributionUrl=https://services.gradle.org/distributions/gradle-6.0.1-all.zip

在此版本中使用了不推荐使用的Gradle功能，使其与Gradle 6不兼容
