Could not init mockmaker InlineStaticMockMaker neither InlineDexmakerMockMaker

[GianpaMX]

Hello,

I'm having an issue when mocking a class in an App module.

Release: Android 10 10.0.0.196C69Device: HUAWEI ELE-L04
This error occured due to an I/O error during the creation of this agent: java.io.IOException: Unable to dlopen libdexmakerjvmtiagent.so: dlopen failed: library "libdexmakerjvmtiagent.so" not found

Potentially, the current VM does not support the jvmti API correctly

Causing this error:

adb logcat

The weird thing is, it works in a Library module.

I created the following project with an app module and a library module to reproduce the issue:
https://github.com/GianpaMX/MockMakerIssue

I'm running theses tests in an Android 10 device (HUAWEI ELE-L04)

This is very similar to #119 and #127

Thank you,

Hi @GianpaMX thanks much for reporting and for the sample project! I'm still digging into this bug - I've found the source of the problem, and am working on a proper fix.

The cause is the change to native library compression introduced in AGP 3.6 (https://developer.android.com/studio/releases/gradle-plugin#extractNativeLibs). This is resulting in the app not being able to find the native library it needs to connect to the JVMTI.

A workaround for now is to opt-out of that feature for your test APK using the android:extractNativeLibs="true" flag in the manifest. You can do this by placing an AndroidManifest.xml file in your androidTest/ folder, and it will be used for the android test apk.

I'll keep this thread updated as we investigate a fix on the dexmaker side to make that unnecessary, but wanted to share it for now.

Awesome @kkoser,

I can confirm the workaround works

Thank you,

I wasn't able to find a solution for this, so I've opened https://issuetracker.google.com/u/1/issues/160108941 with the AGP team for this, hopefully they can provide some better guidance on a long term answer here.

Hi,
I encountered similar errors while building test app on Q-AOSP with .bp

Since I'm working on AOSP, I started with including below library - Android version of dexmaker - to static :

...
static_libs: [
  "mockito-target-inline",
  ...,
],
jni_libs: ["libdexmakerjvmtiagent", "libstaticjvmtiagent"],
...

First time my app was able to extract .so files but could not attach libraries. (returned -3, which means JNI_EVERSION)
The solution was add android:debuggable="true" option to <application...> tag on AndroidManifest.xml
Because android mandates art runtime to attach JVMTI when only started with debuggable flag
Hope it would help some other person who'll come here later..

Workaround above doesn't work anymore.

The error is:
error: existing attribute extractNativeLibs="true" conflicts with --extract-native-libs="false"

android:debuggable="true"
doesn't help much as well

In my case target has no libstaticjvmtiagent.so on it's disks. How do I properly install it?

Workaround above doesn't work anymore.

The error is:
error: existing attribute extractNativeLibs="true" conflicts with --extract-native-libs="false"

android:debuggable="true"
doesn't help much as well

this conflict can be solved by using "use_embedded_native_libs: true"
but you will see another error:
"Mockito could not self-attach a jvmti agent to the current VM. This feature is required for inline mocking.
This error occured due to an I/O error during the creation of this agent: java.io.IOException: Initialization of libdexmakerjvmtiagent.so returned non-zero value of -3"

Hi, do we have any solution to this? I am trying to run unit tests with mockito but failing in 14 but all is fine in the lower version.
Please, suggest and help I need to push some with this fix. I tried the provided but didn't work also we don't use the androidTest
