AAPT: error: attribute android:singleline not found.

This error occurs when you try to use the attribute "android:singleline" in your XML code, but it is not recognized by the Android Asset Packaging Tool (AAPT).
This attribute was deprecated in API level 26 and removed in API level 28. Instead, you should use the "android:maxLines" attribute with a value of "1" to achieve the same effect.
To fix this error, replace "android:singleline" with "android:maxLines="1"" in your XML code.

AAPT: error: attribute android:android.support.v7.widget not found.
The error message indicates that there is no attribute called "android.support.v7.widget" in your Android project. This attribute was commonly used in older versions of Android and has been replaced with "androidx.appcompat.widget" in newer versions.
To fix the error, you need to replace all occurrences of "android.support.v7.widget" with "androidx.appcompat.widget" in your project's XML files. You can do this manually or by using the "Refactor" option in Android Studio.
Also, make sure that you have added the necessary dependencies for the AppCompat library in your project's build.gradle file. You can add the following lines to the dependencies section of your build.gradle file to use the latest version of AppCompat:
```
implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.3.0'
```
After making these changes, clean and rebuild your project to ensure that the changes are applied correctly.
AAPT: error: style attribute 'android:attr/forceDarkAllowed' not found.
这个错误通常是因为你的项目使用的是较旧版本的Android Gradle插件,而该插件不支持`android:attr/forceDarkAllowed`属性。尝试升级你的Android Gradle插件版本以解决这个问题。
具体步骤如下:
1. 打开项目的`build.gradle`文件。
2. 在`dependencies`部分找到`classpath 'com.android.tools.build:gradle:版本号'`。
3. 将版本号更新为最新版本,例如`4.2.0`。
4. 点击"Sync Now"按钮,等待Gradle同步完成。
5. 重新构建你的项目,这个错误应该就会消失了。
如果你的项目使用的是较旧版本的Android Studio,则可能需要更新Android Studio本身以获取最新版本的Android Gradle插件。
