Ошибки Proguard при создании подписанного APK

В моем файле build.gradle для minifyEnabled установлено значение true. Я получаю много ошибок при создании подписанного APK для моего приложения:

Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.

> java.io.IOException: Please correct the above warnings first.

Поэтому я добавил эти строки в файл progard-rules.pro:

-keep com.dropbox.** {*;}
-keep com.google.common.** {*;}
-keep com.square.picasso.** {*;}

Но затем я получаю эту ошибку:

Warning:Exception while processing task java.io.IOException: proguard.ParseException: Unexpected keyword 'com.dropbox.**' in line 18 of file '/home/AndroidProjects/Poolex/app/proguard-rules.pro'
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.IOException: proguard.ParseException: Unexpected keyword 'com.dropbox.**' in line 18 of file '/home/AndroidProjects/Poolex/app/proguard-rules.pro'

Как мне это решить?

Если вы хотите, вы можете игнорировать все ошибки от proguard и попробовать, работает ли приложение. Я использую этот
-dontwarn **
для игнорирования всех ошибок. Если это не работает, попробуйте с:
-keep **
А если вы хотите сделать это только с одним, используйте как
-keep class com.dropbox.**
или
-ignore com.dropbox.**

Добавьте к proguard-rules.pro этому:

-dontwarn okio.**
-dontwarn okhttp3.**
-dontwarn com.squareup.okhttp.**
-dontwarn com.google.appengine.**
-dontwarn javax.servlet.**
# Support classes for compatibility with older API versions
-dontwarn android.support.**
-dontnote android.support.**

Убедитесь, что в build.gradle(Module:app) у вас есть:

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

внутри блока android > buildTypes > release.

Попробуй это:

-keep class com.dropbox.** {*;}
-keep class com.google.common.** {*;}
-keep class com.square.picasso.** {*;}
