Android：导入module报错Android resource linking failed
今日将A工程（调试无问题）生成module导入B工程时报错，如下：
Android resource linking failed

Daemon: AAPT2 aapt2-3.2.0-4818971-windows Daemon #0很显然这是使用constraintlayout时资源索引异常，此时我在module中对constraintlayout的依赖方式如下：
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
...
compileOnly(name: 'constraint-layout-1.1.3', ext: 'aar')
...
}有些网友分享说解决此问题的方式是在主工程app下的gradle中加入如下依赖：
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'果然，加入如上语句后编译成功！但是问题来了：在app gradle中引用的androidx资源包，在module中引用的android aar，而且具体使用只是在module下而非app框架，这样解决很可能造成引用混淆，存在不确定风险。我打算不使用该方案（删掉implementation 'androidx.constraintlayout:constraintlayout:1.1.2'），继续解决此问题。
既然编译时报错，是否app编译时用到了module的资源索引呢，因此将module中的资源引用方式修改如下：
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
...
implementation(name: 'constraint-layout-1.1.3', ext: 'aar')
...
}报错找不到该资源如下：
Could not find :constraint-layout-1.1.3:.
Searched in the following locations: file:/E:/WorkSpace/ASProjects/Task/demo/app/libs/BaseRecyclerViewAdapterHelper-2.9.30.aar
Required by:
project :app > project :module_aiview既然这种写法找不到libs下的资源，那就直接用AS标准加载lib的方式：在File→Project Structure→...。加载完后在dependencies中的依赖方式自动添加为
implementation files('libs\\constraint-layout-1.1.3.aar')重新编译工程，问题解决。
