我试图从 Android创建一个发布apk文件,但当我创建一个PNG图像的发布apk时,我得到重复资源错误.最初我认为这种情况正在发生,因为我在现有项目中犯了一个错误,但是当我创建一个带有单个
>创建一个应用程序 – react-native init demo
>在项目根文件夹中创建资产文件夹.
>在assets文件夹中添加PNG图像.
>现在使用上面的PNG图像实现Image组件.
>现在使用cmd捆绑它
react-native bundle –platform android –dev false –entry-file index.js –bundle-output android / app / src / main / assets / index.android.bundle –assets-dest android / app / src /主/ RES /
>然后使用Android Studio的Generate Signed APK生成发布apk.
这将抛出以下错误：
[drawable-mdpi-v4/assets_mario] /Users/jeffreyrajan/Tutorials/RN/errorCheck/android/app/src/main/res/drawable-mdpi/assets_mario.png [drawable-mdpi-v4/assets_mario] /Users/jeffreyrajan/Tutorials/RN/errorCheck/android/app/build/generated/res/react/release/drawable-mdpi-v4/assets_mario.png: Error: Duplicate resources :app:mergeReleaseResources FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:mergeReleaseResources'. > [drawable-mdpi-v4/assets_mario] /Users/jeffreyrajan/Tutorials/RN/errorCheck/android/app/src/main/res/drawable-mdpi/assets_mario.png [drawable-mdpi-v4/assets_mario] /Users/jeffreyrajan/Tutorials/RN/errorCheck/android/app/build/generated/res/react/release/drawable-mdpi-v4/assets_mario.png: Error: Duplicate resources * Try: Run with --stacktrace option to get the stack trace.

注意：当您生成没有任何PNG图像的版本apk时,您将不会收到任何错误,它将为您创建发布apk.
这是其他文件代码.

对此有何解决方案？
更新：
这是其他细节
classpath 'com.android.tools.build:gradle:3.1.4'
ext {
buildToolsVersion = "27.0.3"
minSdkVersion = 16
compileSdkVersion = 27
targetSdkVersion = 26
supportLibVersion = "27.1.1"
}
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
尝试使用Android Studio 3.0,3.0.1,3.1,3.1.4& 3.2
在尝试了很多解决方案后,我发现只有两个解决方案正在运行.他们来了解决方案1：
捆绑后从Android Studio中删除drawable文件夹.你可以在android / app / src / main / res / drawable中找到它
解决方案2：
在此解决方案中,您无需删除任何可绘制文件夹.只需在react.gradle文件中添加以下代码即可在node_modules / react-native / react.gradle路径下找到
doLast {
def moveFunc = { resSuffix ->
File originalDir = file("$buildDir/generated/res/react/release/drawable-${resSuffix}");
if (originalDir.exists()) {
File destDir = file("$buildDir/../src/main/res/drawable-${resSuffix}");
ant.move(file: originalDir, tofile: destDir);
}
}
moveFunc.curry("ldpi").call()
moveFunc.curry("mdpi").call()
moveFunc.curry("hdpi").call()
moveFunc.curry("xhdpi").call()
moveFunc.curry("xxhdpi").call()
moveFunc.curry("xxxhdpi").call()
}
