Dependency：

debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.0-beta-3'

不集成的时候，都是可以运行的，一集成之后就跑不了。项目是使用了AndroidX的，语言是java

Edit with translation from Google translate:

When it is not integrated, it can be run, and it cannot run after integration. The project uses AndroidX and the language is java

[Armaxis]

Hello!
It looks like the LeakCanaryFileProvider is not present in the final apk, while being present in the AndroidManifest.xml as a content provider (this is done my leakcanary, it's correct).

With the LeakCanaryFileProvider being a part of -core package it's quite surprising it didn't made its way to the apk. Are you using code shrinker on the debug builds?

Also, can you please share the part of gradle script where you add dependency on Leakcanary? Just want to make sure it's been set up properly.

[CaiJinFu]

This is my dependence
debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.0-beta-3'

[Armaxis]

Dependency looks correct.
Does the issue remain if you try using 2.0-beta-2 version of the lib?

[CaiJinFu]

yes,I still have problems with this version 2.0-beta-2. I guess if I used Alibaba's hotfix.I have 2 Applications.This is my wrong log.SophixStubApplication is the application of hotfix.There is also a my own application.

[forJrking]

me too

[meablelee2013]

I meet the same issue.
do not debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.0-beta-3' the application is ok,but do it,even if add -keep class leakcanary.internal.LeakCanaryFileProvider
to multidex-config.pro,it still show the this error.

[mikilangkilo]

me too,i also use

-keep class leakcanary.** {*;}

in proguard and multidex-config

still not work

and in output.apk i can find the provider registered in AndroidManifest.xml.

and no problem happened to other provider

[afinal]

I have this problem too

[pyricau]

Please refrain from adding "me too" comments that don't provide any insights, and use 👍 reactions instead.

Questions for those having the issue:

• do you use proguard? Anyone having this issue and not using proguard?
• can you provide a sample project that reproduces the issue?
• can you provide an APK that reproduces the issue?
• Is the LeakCanaryFileProvider class included into the dex files of your APK? If yes, is it in the main dex or secondary dexes?
• does anyone have this problem in a single dex app?

We should definitely add the provider to our proguard rules, same as the installer. Though I'm not sure if that's the root cause here.

[pyricau]

Note: I will delete "me too" comments as well as comments that aren't in English.

[zhuruyi2013]

i meet this problem too.
And I decompile the apk to see leakcanary core code，but only has a R.java.
my project define flavor，and i compile use “devDebug” build variant.

this is my import code :
debugCompile compileDependencies.leakCanaryDebug。
my gradle version is too below， 3.3.

i think reason of this problem may be Depend on the isolation.
api or implemention？

[Armaxis]

@zhuruyi2013 try using debugImplementation instead of debugCompile. Let us know if that helps.

[pyricau]

I don't see howdebugCompile or debugImplementation can make a difference, looks like a class is missing. We need a sample project to investigate this further, and if none can be provided then I'll close this issue.

[shumidub]

I have simmilar error (Unable to get provider leakcanary.internal.AppWatcherInstaller: java.lang.ClassNotFoundException: Didn't find class "leakcanary.internal.AppWatcherInstaller) :

It is not reproduce stable. Only some users from thousand of users have this error. I use R8, and split apk.
My dependencies looks like

    implementation "com.squareup.leakcanary:leakcanary-object-watcher-android:2.0-beta-3"
    debugImplementation "com.squareup.leakcanary:leakcanary-android:2.0-beta-3"

My proguard rules include this:

-dontwarn com.squareup.haha.guava.**
-dontwarn com.squareup.haha.perflib.**
-dontwarn com.squareup.haha.trove.**
-dontwarn com.squareup.leakcanary.**
-keep class com.squareup.haha.** { *; }
-keep class com.squareup.leakcanary.** { *; }
-dontwarn android.app.Notification

[pyricau]

Can you provide a project that we can use to reproduce this issue?

Note that your proguard rules are not correct anymore (these are for leakcanary 1.0) but this should be ok because the new version has its proguard rules included.

[shumidub]

I can not provide the project, because it is my company production app. And I can not reproduce this issue. It happends only with little count of users .

[pyricau]

"It happends only with little count of users" => Are you using the object watcher in production? If you have no need for it you can set it as a debug dependency (which should be the default when you add leakcanary) and that way it won't ship in production.

"It happends only with little count of users" => Are you using the object watcher in production? If you have no need for it you can set it as a debug dependency (which should be the default when you add leakcanary) and that way it won't ship in production.

I use dependencies:

implementation "com.squareup.leakcanary:leakcanary-object-watcher-android:2.0-beta-3" 
debugImplementation "com.squareup.leakcanary:leakcanary-android:2.0-beta-3"

If I remove implementation "com.squareup.leakcanary:leakcanary-object-watcher-android:2.0-beta-3" I get compilation error, because something should be imported for non debug build type

[Armaxis]

If I remove implementation "com.squareup.leakcanary:leakcanary-object-watcher-android:2.0-beta-3" I get compilation error, because something should be imported for non debug build type

Can you share the error message you get? LeakCanary is intended to be debug-only dependency; this might be the reason why you get the crashes.

[shumidub]

I have

import leakcanary.AppWatcher

interface ReferenceWatcher {
    fun watch(watchedObject: Any)

    object DISABLED : ReferenceWatcher {
        override fun watch(watchedObject: Any) {}
    }

    object ENABLED : ReferenceWatcher {
        override fun watch(watchedObject: Any) {
            AppWatcher.objectWatcher.watch(watchedObject)
        }
    }
}

and use It as

if (BuildConfig.DEBUG) {
            ReferenceWatcherProvider.setInstance(ReferenceWatcher.ENABLED)
}

If I remove implementation "com.squareup.leakcanary:leakcanary-object-watcher-android:2.0-beta-3" I get compilation error "ReferenceWatcher.kt: (14, 13): Unresolved reference: AppWatcher"

Of course I can provide different ReferenceWatcher for each build types, but we have 10 build variant and it is not usefull to write this for each of them

[Armaxis]

As an alternative you can use reflection to set these, by checking first that the class is available at the runtime. It's more boilerplate, but will work if you can't extract code to some debug-only folder.

[pyricau]

leakcanary-object-watcher-android is meant to be used in production, that's actually ok, though if the content provider class isn't available for a number of users then I have no idea what could cause this.

[devism]

I think I'm getting the same issue.

@devism this is a different issue. Do you have a sample project that reproduces it? If yes can you create a new issue?

[devism]

I do have a sample project that reproduces the issue. I will create a new issue.

[pyricau]

Note to readers: @devism moved their issue to #1662

Everyone else here: which version of the support library (or Android X) are you using?

Can you provide a sample project or an APK that reproduces this consistently?

[pyricau]

Summary of everything that's been reported in this issue:

• @CaiJingFu, @meablelee2013 have a crash because the LeakCanaryFileProvider class is not found. We know they use Android X. We don't know which versions of Android this is crashing on. The crash is 100% reproducible. Seems similar to this Stack Overflow question (not solved). Android X ships its own AppComponentFactory (added here to provide different component impls per version) which is now in charge of creating provider instances. @CaiJingFu mentioned a "hotfix" from Alibaba, I have no idea what that means but apparently that involves having two application classes, one of which is a stub. I wonder what that's about.

Without a sample project to reproduce, it's hard to figure it out. This could be a multidex issue if the Provider class somehow doesn't end up in the main dex.

• @GWYloved wrote they have the same crash, and they mention a provider but did not provide a stacktrace. They do mention multidex, but we don't know if they use AndroidX. We also don't know which version of Android this is running on.

• @forJrking @afinal wrote me too but did not provide any details, so it could be a totally different issue.

• @shumidub has a different error: AppWatcherInstaller cannot be found. They mentioned it doesn't happen systematically, it happens in production for a low number of users. They have a release dependency on the leakcanary-object-watcher-android dependency (which is ok). The app is https://play.google.com/store/apps/details?id=com.tradingview.tradingviewapp . We don't know if this is happening on a specific subset of Android versions or not, a specific manufacturer and we don't know if they've upgraded to Android X or not. The stacktrace doesn't show AppComponentFactory.instantiateProvider so seems different from the original error. This really looks like custom Android builds not loading providers correctly.

• @devism had a similar "Unable to get provider" issue except it was a different cause (classloading issue with really old support library) which has been fixed for a future release.

[JackFung2015]

I solved this problem by use "debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.0-alpha-1'"

[pyricau]

@JackFung2015 There were several distinct problems described here, which one did you solve? Also you should update to 2.1 :)

Using version 2.1 will cause the program to crash directly

[pyricau]

@JackFung2015 if it's a runtime crash of the app then you should have a stacktrace. Can you share that stacktrace?

[gustavofc1997]

currently i am getting this error
java.lang.RuntimeException: Unable to get provider leakcanary.internal.AppWatcherInstaller$MainProcess: android.content.res.Resources$NotFoundException: Resource ID #0x7f040004
looks like similar but in this case cannot find a resource , any idea guys?
and i found this message
Resource 7f040004 is a complex map type. E/InstrumentationResultPrinter: Failed to mark test No Tests as finished after process crash E/MonitoringInstr: Exception encountered by: null. Dumping thread state to outputs and pining for the fjords.

[pyricau]

@gustavofc1997 please file a separate issue and provide the full stacktrace.

[pyricau]

I'm going to close this for now, and lock comments. If you can reproduce this with a sample project then please open a new issue and provide the sample project.
