Android app crash on setting minifyEnabled true

Question

Application getting crashed on enabling minifyEnabled true. When I make it false application starts working fine. Do I need to add something to my pro-guard file? I am not able to figure out what is causing an application to crash.

Here is the Gradle code:

debug {
            manifestPlaceholders = [crashlyticsApiKey: '', mapApiKey: '']
            // Enables code shrinking, obfuscation, and optimization for only
            debuggable true
            // your project's release build type.
            minifyEnabled true
            // Enables resource shrinking, which is performed by the
            // Android Gradle plugin.
            shrinkResources true

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

            buildConfigField "String", "BASE_URL", '"http://"'
            signingConfig signingConfigs.debug
        }

Logcat Output:

The error stack indicates this: Caused by: java.lang.IllegalStateException: Could not read resource entities-xhtml.properties. Make sure you copy resources for l.b.g.i

I think this is because the resource/class l.b.g.i is excluded by ProGuard. You may want to use mappings.txt file (that contains mapping between actual class/method name and its random one generated by proGuard) to decode actual resource name and then force Proguard to keep it, something like this example https://stackoverflow.com/a/5866755/1992013 Hope this helps !

Did u try swithcing off shrinkResources ? u might have to troubelshoot by looking at proGuard output files https://developer.android.com/studio/build/shrink-code.html to understand further. it could be related to data classes obfuscation reference: https://blog.mindorks.com/things-to-care-while-using-proguard-in-android-application. Here is sample proguard file https://github.com/square/retrofit/blob/master/retrofit/src/main/resources/META-INF/proguard/retrofit2.pro – Birender Singh Feb 10 '20 at 12:41
