Some devices won't run tests: "java.lang.VerifyError: Rejecting class X because it failed compile-time verification" about dexopener

Are you testing an Android library?
Or an app?
If you are testing an Android app, it seems strange that the test class is in DexOpener's dex cache.

Could you add the following three lines to your AndroidJUnitRunner#newApplication and show me the logs?

Log.d("YourApp", "context.getApplicationInfo().sourceDir=" + context.getApplicationInfo().sourceDir);
Log.d("YourApp", "getContext().getApplicationInfo().sourceDir=" + getContext().getApplicationInfo().sourceDir);
Log.d("YourApp", "getTargetContext().getApplicationInfo().sourceDir=" + getTargetContext().getApplicationInfo().sourceDir);

The module under test is a library (as in com.android.library gradle plugin) but it's just a module attached to an app project. I was able to reproduce in two different modules with the same result.

Here's the output from your requested debugging:

06-02 11:11:21.034 D/TestRunner: context.getApplicationInfo().sourceDir=/data/app/com.redacted.test-2/base.apk
06-02 11:11:21.034 D/TestRunner: getContext().getApplicationInfo().sourceDir=/data/app/com.redacted.test-2/base.apk
06-02 11:11:21.034 D/TestRunner: getTargetContext().getApplicationInfo().sourceDir=/data/app/com.redacted.test-2/base.apk

Thank you for your reply.

There is one more request.
Could I have all the logs?
If it is impossible, would you please show me the logs tagged as dex2oat?

I created a gist:

It's a lot of noise but should include what you are looking for. It is unfiltered logcat starting at the point I install the app package through the completed run of the test. All the relevant package references will contain com.redacted, and I did find/replace so that the relevant modules show up separately (packageA, packageB, appPackage, authlib, and anotherpackage. Great names, eh?) The test is in packageA, but depends on some things in packageB. The overall packageA depends on packageB, authlib, and anotherpackage.

Anyway, hopefully you find what you're looking for.

Thank you.
I checked your log file and it seems to be a problem of ASMDEX which is a bytecode manipulation library used by DexOpener.

06-02 16:26:55.675 I/dex2oat: Verification error in void com.redacted.packageA.util.MockPackageBManagerModule.<init>()
06-02 16:26:55.675 I/dex2oat: void com.redacted.packageA.util.MockPackageBManagerModule.<init>(): [0xFFFFFFFF] invalid reg index 1+25 in range invoke (> 25)
06-02 16:26:55.675 W/dex2oat: Verification failed on class com.redacted.packageA.util.MockPackageBManagerModule in /data/data/com.redacted.packageA.test/code_cache/dexopener/classes114178148.zip because: Verifier rejected class com.redacted.packageA.util.MockPackageBManagerModule due to bad method void com.redacted.packageA.util.MockPackageBManagerModule.<init>()

The dex2oat which is a DEX code compilation tool failed bytecode verification.
According to the second line, register size overflow has occurred.

ASMDEX is an old library, so we plan to change it to other newer libraries, but it will take time.
If you cannot wait, we recommend kotlin-allopen plugin instead.

We have released a new version 0.9.9 using Smali instead of ASMDEX.
This problem may be solved, so please try it.

[gefilte]

This seems to have solved the problem. Thanks!
