    # Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\Hemo\AppData\Local\Android\Sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

First When i make a Signed Apk

Answer 1

You have to write proguard rules for greendao.

Here is the link for greenDAO proguard rules . copy and paste in your proguard rules file.

Answer 2

Add

### greenDAO 3
-keepclassmembers class * extends org.greenrobot.greendao.AbstractDao {
    public static java.lang.String TABLENAME;
 }
 -keep class **$Properties

# If you do not use SQLCipher:
-dontwarn org.greenrobot.greendao.database.**
# If you do not use RxJava:
-dontwarn rx.**

### greenDAO 2
-keepclassmembers class * extends de.greenrobot.dao.AbstractDao {
    public static java.lang.String TABLENAME;
}
-keep class **$Properties

to your proguard rules. Shamelessly stolen from here
