Leakcanary: Unable to get analysis: LeakCanary.Config.dumpHeap is false

[jordantrain]

Description

I am unable to get an analysis after installing Leak Canary in my app.
I get these two lines in my Log Cat:

"Scheduling check for retained objects because found new object retained"
"Ignoring check for retained objects scheduled because found new object retained: LeakCanary.Config.dumpHeap is false"

So no dump is performed and no analysis carried out.

Using debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.2' in Gradle
Gradle 3.5.0
compileSdkVersion 28
targetSdkVersion 28
I am testing on a real device running Android 9

JUnit is not on the build path as this was noted to be a problem in previous releases of Canary Leak.

Hi @jordantrain ! Sorry for the delayed response. This seems to be the source of the issue:

LeakCanary.Config.dumpHeap is false

Do you have any code referencing LeakCanary, or did you simply add the dependency?

Any chance you could come up with a repro case in a sample app?

If you filter the logs, you should find a log early on app start that indicates that dumpHeap was set to false and hopefully you can figure out why.

I am facing the same issue.
I only added the debug dependency in Gradle file. I am getting the following log:
LeakCanary heap dumping is disabled: LeakCanary.config.dumpHeap = false

@guneetkaur can you filter Logcat on the LeakCanary tag and then paste here all of the logs from the beginning of app start?

Here are the logs

See that first line:

D/LeakCanary: org.junit.Test detected in classpath, app is running tests => disabling heap dumping & analysis

Normal Android applications don't have @Test in their classpath unless they're running test. However, sometimes 3rd party library bring it in as a dependency (e.g. retrofit mock webserver). One way to work around that is that have change the test detection to a different class that is really only used in tests:

<resources>
  <string name="leak_canary_test_class_name">assertk.Assert</string>
</resources>

Closing as this doesn't look like a LeakCanary bug.

Just check your build.gradle (app) and change "implementation" to "testImplementation" or "androidTestImplementation" for junit/test:runner/espresso and etc.
