Android 关于Bug error: resource an

简单记录

由于工程targetSdkVersion升级到28之后，并且compileSdkVersion 也使用28之后就会出现上述报错。这是由于一些第三方库没有做及时的兼容。很多React Native工程第三库都会报这个错误。如下所示

<pre class="console-output" style="box-sizing: border-box; white-space: pre-wrap; word-wrap: break-word; margin: 0px; position: relative; font-size: 14px; background: rgb(38, 50, 56); color: rgb(233, 237, 237); cursor: text; font-family: &quot;Roboto Mono&quot;, monospace !important; padding: 10px 20px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">FAILURE: Build completed with 2 failures.

解决方法

既然知道了是由于编译问题导致的Bug，那么我们强制修改第三库里的targetSdkVersion和compileSdkVersion 就可以了，解决方法如下，在主工程build.gradle文件中加入下段代码，望对大家有帮助！

allprojects {
    repositories {
        google()
        mavenLocal()
        ............
    }
    subprojects {
        afterEvaluate {
            project ->
                if (project.hasProperty("android")) {
                    android {
                        compileSdkVersion = 28
                        buildToolsVersion = "28.0.3"
                    }
                }
        }
    }
}
