最近android应用开发中碰到的几个问题，进行了解决。

问题及解决

One or more layouts are missing the layout_width or layout_height attributes

渲染问题： One or more layouts are missing the layout_width or layout_height attributes. These are required in most layouts.

参考Stackoverflow: Rendering Problems NOTE: One or more layouts are missing the layout_width or layout_height attributes. These are required in most layouts，此种问题有建议是清除缓存。
最终的解决办法是加上缺少的属性。

导入库（Library)

首先导入库，File ->Project Structure -> App-> dependencies -> + ->add library，接下来在build.gradle里添加dependencies。

dependencies 

    // Internal application-level dependencies
    implementation fileTree(include: ['*.jar'], dir: 'libs')

    // Internal application library/module dependencies
    implementation project(':libPrinter')

    // Internal application pre-built library/module dependencies
    implementation project(':libraries:libInquiry')

...
以下省略

Task ‘wrapper’ not found in project ‘:app’

报错： Task 'wrapper' not found in project ':app'

解决办法，在相应的build.gradle里添加：

task wrapper(type: Wrapper)
    gradleVersion = '7.2'

Task ‘prepareKotlinBuildScriptModel’ not found in project ‘:app’

报错：Task 'prepareKotlinBuildScriptModel' not found in project ':app'

解决办法，在相应的build.gradle里添加：

task prepareKotlinBuildScriptModel 

error: resource color类型错误

报错： error: resource color/purple_500 not found

解决办法，在color.xml中把颜色类型添加上：

    <color name="purple_200">#FFBB86FC</color>
    <color name="purple_500">#FF6200EE</color>
    <color name="purple_700">#FF3700B3</color>
    <color name="teal_200">#FF03DAC5</color>
    <color name="teal_700">#FF018786</color>
