Android Studio生成签名apk无法正常工作2

Question

I used older android studio version to built my app and now I have the last version.When I want make signed apk I give errors because I want to use proguard and proguard-rules.pro is not exists.I built it manually in app folder but I still encountering errors.When I remove 'proguard-rules.pro' into build.gradle the problem is solving but I want to use proguard with rules because sum classes and sum files not working when minifyEnabled is true and 'proguard-rules.pro' is removed from this code proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' into build.gradle .

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.FileNotFoundException: C:\Users\Hossein\Desktop\Root\app\proguard-rules.pro (The system cannot find the file specified)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

将名为proguard-rules.pro的文件添加到项目的Root\\app\\ ，然后再次对您的应用程序进行签名。
