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!
Similar question The answer does not work.
回答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.
回答2:
Add this to your proguard file. This will not apply obfuscation to your library
-keep class com.esri.** { *; }
-keep interface com.esri.** { *; }
回答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.

I had the same issue and solved as explained in this link on Esri GeoNet.
Based on what EsriStaff wrote:
Yes, I agree that this is most likely what's happening. I can see in the path above that arm64 paths are involved, and also there was a comment above that things work OK, until another dependency is added. Given those two points, it's very possible you're running in to the problem where once Android has loaded a 64-bit native library, it no longer loads 32-bit libraries. [...] The ArcGIS Runtime SDK provides 32-bit armeabi-v7a library, which would normally be loaded when running on 64 bit, as its forwardly compatible, which would explain why you're finding things OK until you add more dependencies.
As the SO question linked in EsriGeoNet suggests the solution is to add this inside your app.gradle file:
android {
....
defaultConfig {
....
ndk {
abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
}
}
}
At this point running the gradle build should give you a NDK deprecated integration error that you can solve by adding this inside your gradle.properties (Global properties) file:
android.useDeprecatedNdk = true
I've tested on a Samsung S6 with Android 6.0.1 and works fine.
In addition to this I've found out that the issue was already there in ArcGis Android SDK v10.2.3 and that upgrading to the latest v10.2.8.1 does not fix the issue.
Next week our staff has a scheduled meeting with Esri Italian office and I'll ask details about this bug and if / when it is going to be fixed.
Hope this helps you and anyone else having this issue.
