ReactNative 错误锦集

错误1:

......android/app/build/intermediates/res/merged/release/drawable-hdpi/node_modules_reactnavigationstack_dist_views_assets_backicon.png: error: uncompiled PNG file passed as argument. Must be compiled first into .flat file..

error: failed parsing overlays.

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':app:processReleaseResources'.

> Failed to process resources, see aapt output above for details.

* Try:

Run with **--stacktrace** option to get the stack trace. Run with **--info** or **--debug** option to get more log output. Run with **--scan** to get full insights.

* Get more help at [https://help.gradle.org](https://help.gradle.org)

解决的办法
原因及解决方法：在gradle.properties文件中添加以下行：android.enableAapt2 = false，它实质上使用旧的aapt来获取资源。

 

错误2:

....../android/app/build/intermediates/res/merged/release/drawable-hdpi-v4/node_modules_reactnavigationstack_dist_views_assets_backicon.png: error: Duplicate file.

在这个目录下的文件node_modules/react-native/react.gradle文件中添加：

在doFirst块之后 添加以下代码到里面

doLast {
    def moveFunc = { resSuffix ->
        File originalDir = file("${resourcesDir}/drawable-${resSuffix}")
        if (originalDir.exists()) {
            File destDir = file("${resourcesDir}/drawable-${resSuffix}-v4")
            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()
}
