Proguard Fehler beim Generieren von signierten APK

Question

Ich habe MinifyEnabled auf True in meiner Build.Gradle-Datei festgelegt. ich viele Fehler erhalten, während eine signierte APK für meine Anwendung zu erzeugen:

Warning:Exception while processing task java.io.IOException: Please correct the above warnings first. 
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'. 
> java.io.IOException: Please correct the above warnings first. 

Also ich diese Zeilen in der progard-rules.pro Datei hinzugefügt:

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

Aber dann bekomme ich diese Fehler:

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' 

Wie löse ich das?

Answer 1

Wenn Sie möchten, können Sie alle Fehler aus proguard ignorieren und versuchen, ob die App funktioniert. Ich verwende diese
-dontwarn **
, um alle Fehler zu ignorieren. Wenn es nicht funktioniert, versuchen Sie mit:
-keep **
Und wenn Sie es nur mit einem tun möchten, verwenden Sie wie
-keep class com.dropbox.**
oder
-ignore com.dropbox.**

Answer 2

Try this:

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

Answer 3

zu proguard-rules.pro In diesem:

-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.** 

Stellen Sie sicher, in build.gradle(Module:app) Sie bekam:

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

innerhalb der android>buildTypes>release Block.
