Amazon java.lang.VerifyError Android

Question

I have been trying to submit 2 separate apps into the Amazon App store but they keep being rejected. Here is the stack trace for the first:

I see the same verify error on both but I can't figure it out. The only common library used between the 2 apps is the FlurryAgent.jar for analytics.

For the top app I have For the bottom app I have in the manifests. The only information I have been able to find out is about libraries (GSON) and needing to use dx but I am using Eclipse so that doesn't help.

To make this more difficult, the error does NOT occur on the Android Market. Yet the testers at Amazon say that it FC 5/5 times on each of their devices (I tried using an emulator for their test devices and they worked fine). I know they use "wrapper" code around my app and I think it must be interfering in some way.

Does anyone have any experience with this?

I had a similar problem - resolved it by removing the non activity class from AndroidManifest.xml

Amazon injects their own code into your apps Activities life-cycle events. Knowing that and looking at the log you've provided:

10-12 15:41:50.359 W/dalvikvm( 2644): VFY: Lcom/companionfree/pushup/WorkoutDbAdapter; is not instance of Landroid/app/Activity;

It appears that Amazon's code tried to instrument a class (WorkoutDbAdapter) which is NOT an Activity (doesn't extends Activity), ending up being rejected by the JVM's verifier.

With my app this happened since the class was listed was listed an an Activity on AndroidManifest.xml. Removing this listing from AndroidManifest.xml resolved the issue and the app was admitted to the market.

Sarp wrote that renaming your class' packaged solved the issue, perhaps by doing so you've made your listing on AndroidManifest.xml no longer relevant. Thereby circumventing the problem.

I just solved my problem and may help to you

I just update the AS to 2.0 and ADT, and the verify issue come out finally, be careful with the constructor like:

class abc {
  abc(int x) {
    ....
  }
  abc(byte x) {
    ....
  }
}

I'd say this is the problem of the Amazon. Apparently they are injecting some DRM code into your apk: Injecting code into APK

Other people are seeing similar errors - Android app issue (Amazon)

Yeah I found those. I guess I will just contact Amazon and see what they say. It's really frustrating though. Terrible experience with their appstore. – easycheese Nov 12 '11 at 18:19

In my case, the class that was causing a VerifyError was in a package called util. It was probably clashing with an injected package by Amazon, because renaming it to utils solved the problem.

Because our app was using Facebook SDK, it was given a "No, I will sign my binary" option when uploading a new binary. When you upload an unsigned APK this way, Amazon will let you download the processed binary (that includes their injected code) as Step 2 so that you can sign it. I was able to download a copy of my APK that crashes, and test my changes without going through the approval process this way.

How do you go about doing this? – easycheese Jun 02 '12 at 15:13 — easycheese, Jun 02 '12 at 15:13
