Android SDK (r20 या उच्चतर)
कृपया पूर्वनिर्धारित proguard.config को देखें। project.properties में संदर्भित
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt

यहां आप एक ऐसी "डिफ़ॉल्ट" फ़ाइल की जांच कर सकते हैं जिसे मैं अपडेट करता रहता हूं: https://medium.com/code-procedure-and-rants/android-my-standard-proguard-ffeceaf65521
Android SDK (r19 या उससे कम)
आप इसे default.properties में जोड़ सकते हैं। मैं एक समस्या के बिना अब तक मैन्युअल रूप से जोड़ रहा हूं।
यदि आप लाइन जोड़ते हैं:
proguard.config=proguard.cfg
जैसा कि कहा गया है कि यह केवल हस्ताक्षर किए गए एप्लिकेशन को निर्यात करते समय ProGuard का उपयोग करेगा (Android उपकरण => निर्यात हस्ताक्षरित एप्लिकेशन)
यदि आप एंड्रॉइड 2.3 से पहले एसडीके के साथ प्रोजेक्ट शुरू करते हैं, तो proguard.cfgफ़ाइल नहीं बनाई जाएगी ( default.properties2.3 के रूप में अगले )।
इसे स्वचालित रूप से सक्षम करने के लिए, बस एंड्रॉइड 2.3 के एसडीके को अपडेट करें और मौजूदा स्रोतों (जो आपके वर्तमान में परियोजना के स्रोत हैं) के साथ एक नया प्रोजेक्ट बनाएं।
स्वचालित रूप से proguard.cfgभरना होगा।
यदि फिर भी, आप इसे मैन्युअल रूप से बनाना चाहते हैं तो यह होना चाहिए:
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontwarn android.support.**
-verbose
-dontoptimize
-dontpreverify
-keepattributes *Annotation*
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment
-keepclasseswithmembernames class * {
native <methods>;
}
-keepclasseswithmembernames class * {
public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembernames class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers public class * extends android.view.View {
void set*(***);
*** get*();
}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
मुझे लगता है कि मैंने उपरोक्त सभी प्रश्नों का उत्तर दिया है।

एक लाइन लाइन स्पष्टीकरण द्वारा:
#Use 5 step of optimization
#-optimizationpasses 5
#When not preverifing in a case-insensitive filing system, such as Windows. This tool will unpack your processed jars,(if using windows you should then use):
-dontusemixedcaseclassnames
#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses
# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
-dontwarn android.support.**
#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose
#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).
#To understand or change this check http://proguard.sourceforge.net/index.html#/manual/optimizations.html
#-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.
#To repackage classes on a single package
#-repackageclasses ''
#Uncomment if using annotations to keep them.

सबसे हाल ही में ADT / Proguard के -keepclasseswithmembersबजाय का उपयोग करें-keepclasseswithmembernames
