Error occurred in running app in device:

I use: Android Studio 1.0.2 and ArcGIS SDK 10.2.5

There is no problem if the app is run by Android Studio. Error occurred if the app is generated in APK, install in a device, and then run.

Is there any solution?

Thank you very much!

Answer 1

Your issue is with ProGuard. When you deploy the app in release mode, ProGuard kicks in and minifies all your methods / classes / variables / etc. What this means is that if a method was once called "doSomething()", it will be renamed to something like "a()". This is good because when this happens on all your code, it makes your code smaller and faster.

This can be a problem with working with the NDK, because the way a native library communicates with Java methods is via reflection, which requires naming consistency (methods are found by textual name. If the name changes, the method cannot be found).

You can overcome this issue by editing your ProGuard file to exclude certain classes.

For example, in your case, I would add the following line in your ProGuard file:

-keep class com.esri.core.runtime.LicenseImpl { *; }

Actually, you can make this rule even more specific to only exclude the problematic method:

-keep class com.esri.core.runtime.LicenseImpl { 
    public void nativeIsClientIdValid(...);
}

ProGuard is pretty powerful when it comes to deciding which portions of the code are minified or not, so I would suggest reading up on it.

It is possible that there are other classes which need to be excluded from ProGuard in a similar way, so if you continue getting similar errors after adding this fix, simply add more ProGuard rules, depending on which methods / classes are not being found.

Edit:

According to the new error you're getting, it seems proguard is refactoring annotations and this may likely be the cause of your new error. Add the following flag to exclude annotations:

-keepattributes *Annotation*

Edit 2:

According to this blog about migrating projects to Android studio in the Esri website, it seems that they have not yet found a way to overcome ProGuard issues themselves, as they recommend to set enableMinify to false. This could mean either that the Esri package simply does not working with minification at this time, or that they are haven't invested time in figuring out how to solve the issue.

Answer 2

Add this to your proguard file. This will not apply obfuscation to your library

-keep class com.esri.** { *; }
-keep interface com.esri.** { *; }

Answer 3

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

worked for me.
