JNI DETECTED ERROR IN APPLICATION: JNI FindClass called with pending exception java.lang.ClassNotFoundException: Didn't find class "com.esri.arcgisruntime.ArcGISRuntimeEnvironment"

Question

I enabled R8 in my application in `gradle.properties` file

android.enableR8 = true

along with this I enabled these in app-level build.gradle

release {
minifyEnabled true
shrinkResources true
zipAlignEnabled true
}

I have tried to add the following things to keep these at run time.

-keep class com.esri.** { *; }
-keep interface com.esri.** { *; }
-keep class org.codehaus.jackson.** { *; }
-dontwarn org.codehaus.jackson.map.ext.**
-dontwarn jcifs.http.**

Reference: com.esri.arcgis.android:arcgis-android:10.2.6-2 with proguard - Stack Overflow

But still am facing the same issue.

Error message when I run the app:

JNI DETECTED ERROR IN APPLICATION: JNI FindClass called with pending exception java.lang.ClassNotFoundException: Didn't find class "com.esri.arcgisruntime.ArcGISRuntimeEnvironment" on path: DexPathList

Can you please help me with this.

Hi Shylendra Madda‌,

Have you tried setting R8 to false?

Such as:

android.enableR8 = false

As pointed out by the android developer documentation, R8 might run into issues when the library calls JNI code. More here: Shrink, obfuscate, and optimize your app  |  Android Developers

Give that a try and let me know if that works for you.
