Android 打包release版本时报错如下：
> Task :printlib:minifyReleaseWithR8 FAILED
AGPBI: {"kind":"error","text":"Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /Users/mac/Documents/code/PrintDemo/printlib/build/outputs/mapping/release/missing_rules.txt.","sources":[{}]}
AGPBI: {"kind":"error","text":"Missing class com.hw.hwbaselib.adapter.BaseRvAdapter (referenced from: void com.hw.printlib.adapter.BluetoothDeviceAdapter.<init>() and 1 other context)","sources":[{}],"tool":"R8"}Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /Users/mac/Documents/code/PrintDemo/printlib/build/outputs/mapping/release/missing_rules.txt.Missing class com.hw.hwbaselib.adapter.BaseRvAdapter (referenced from: void com.hw.printlib.adapter.BluetoothDeviceAdapter.<init>() and 1 other context)解决方案：
查看AGP依赖的版本，项目中依赖的AGP版本如下：
[versions]
agp = "8.5.1"
这个版本太高了，容易出现混淆打包的问题，修改成如下版本就可以解决问题了
[versions]
agp = "8.3.2"
如果改完了还是报错，如下：
> Task :app:minifyReleaseWithR8 FAILED
AGPBI: {"kind":"error","text":"Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /Users/mac/Documents/code/PrintDemo/app/build/outputs/mapping/release/missing_rules.txt.","sources":[{}]}
AGPBI: {"kind":"error","text":"Missing class javax.annotation.Nullable (referenced from: okio.Segment okio.Buffer.head and 2 other contexts)","sources":[{}],"tool":"R8"}Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /Users/mac/Documents/code/PrintDemo/app/build/outputs/mapping/release/missing_rules.txt.Missing class javax.annotation.Nullable (referenced from: okio.Segment okio.Buffer.head and 2 other contexts)需要把上述报错中的这句话中的txt文件中的内容，复制到当前module的混淆配置文件中，
Missing classes detected while running R8. Please add the missing
classes or apply additional keep rules that are generated in
/Users/mac/Documents/code/PrintDemo/app/build/outputs/mapping/release/missing_rules.txt
在电脑中找到这个文件，打开，如下：
我的这个missing_rules.txt文件中，内容是这样的，每个项目可能不一样，直接复制里面内容，放到混淆文件中就可以了
# Please add these rules to your existing keep rules in order to suppress warnings.
# This is generated automatically by the Android Gradle plugin.
-dontwarn javax.annotation.Nullable
最后打包就成功了
