我正在尝试将Proguard应用到我的发布应用程序，但到目前为止，我一直在收到错误。调试构建完美：

我已将以下规则添加到我的proguard-rules.pro文件中：
#for support library
# support design
-dontwarn android.support.design.**
-keep class android.support.design.** { *; }
-keep interface android.support.design.** { *; }
-keep public class android.support.design.R$* { *; }
#Support v7
# Hide warnings about references to newer platforms in the library
-dontwarn android.support.v7.**
# don't process support library
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
#Support v4
# Hide warnings about references to newer platforms in the library
-dontwarn android.support.v4.**
# don't process support library
-keep class android.support.v4.** { *; }
-keep interface android.support.v4.** { *; }
我不知道该怎么做 - 错误描述并不是真的告诉我所以我不知道assertionError来自哪里。
有谁知道如何解决这个问题？

在proguard.txt文件中添加这些行应该有帮助。
ALTER TABLE professor
ADD
("Total Budget" varchar2(10),
"Lowest Salary" varchar2(6),
"Highest Salary" varchar2(7)
);
INSERT INTO professor ("Total Budget")
SELECT SUM(pr_salary) FROM professor
WHERE professor.pr_salary > 80000 AND professor.pr_title='Professor';
INSERT INTO professor ("Lowest Salary")
SELECT MIN(pr_salary) FROM professor
WHERE professor.pr_salary > 80000 AND professor.pr_title='Professor';
INSERT INTO professor ("Highest Salary")
SELECT MAX(pr_salary) FROM professor
WHERE professor.pr_salary > 80000 AND professor.pr_title='Professor';

所以我对Proguard很陌生，但在调查之后想出了答案。我读了这个网站，你可以对堆栈跟踪进行去混淆，因为堆栈跟踪被混淆了 - 这就是你看到a.a.a或b.b.b等的原因：https://developer.android.com/tools/help/proguard.html
对于mac，您需要导航到此文件夹：
sdk/tools/proguard/bin/
您将在其中看到retrace.sh脚本。您现在需要在此处找到文件夹中的mapping.txt文件：
app/build/outputs/mapping/release/
将其复制到sh所在的bin文件夹中。然后，您需要复制要对其进行去混淆的堆栈跟踪部分，并将其粘贴到文本文件中并将其放入bin文件夹中。
使用以下命令在终端中进行反模糊处理：
sh retrace.sh -verbose mapping.txt obfuscated_trace.txt > deobfuscated_trace.txt
打开deobfuscated_trace.txt，您会发现错误实际上指向GSON。我通过导入GSON的proguard规则来修复它。
要检查proguard是否正确运行，您将看到日志现在如下所示：
04-06 21:20:15.453 6853-6853/com.myapp E/y: last vis 3
04-06 21:20:15.463 6853-6853/com.myapp E/y: last vis 3
04-06 21:20:15.480 6853-6853/com.myapp E/y: last vis 3
你可以看到类名现在已被混淆，以前它应该是：
04-06 21:20:15.453 6853-6853/com.myapp E/MyFragment: last vis 3
