Bug report

Posted originally as a discussion but now believe this may be a bug so reposting here.

I am having a problem creating a flutter Android build on Visual Studio. I am getting the following error:

Users/xxxxxxxxxxxx/.asdf/installs/flutter/1.12.13+hotfix.7-stable/.pub-cache/hosted/pub.dartlang.org/firebase_core-0.5.0/android/src/main/java/io/flutter/plugins/firebase/core/FlutterFirebaseCorePlugin.java:92: error: cannot find symbol
() -> {
^
symbol: method metafactory(Lookup,String,MethodType,MethodType,MethodHandle,MethodType)
location: interface LambdaMetafactory
Fatal Error: Unable to find method metafactory
FAILURE: Build failed with an exception.

Please note I have tried using flutter pub cache and then flutter clean.

I believe I have tracked this back to the following line of code line 92 (the fourth line here) in the Java plugin referred to, FlutterFirebaseCorePlugin:

private Task<Map<String, Object>> firebaseAppToMap(FirebaseApp firebaseApp) {
return Tasks.call(
cachedThreadPool,
() -> {
Map<String, Object> appMap = new HashMap<>();
Map<String, String> optionsMap = new HashMap<>();
FirebaseOptions options = firebaseApp.getOptions();
      ………..}

Which seems to suggest that there is something wrong with this plugin.

Thanks for any help and my set up is as described below.

Flutter doctor shows the following:

Please note I have now successfully built to iOS so this is only a problem with the Android build

darshankawar commented 4 years ago

@LeapingSwan Please provide a minimal complete reproducible code sample. In pubspec.yaml you shared, I don't see firebase_core plugin. Also provide how you are using firebase_core plugin to initialize your project. Thanks.

LeapingSwan commented 4 years ago

Hi @darshankawar thanks for coming back to me.

First that's weird that firebase core was not in there. I may have taken it out temporarily at some point in trying to isolate the problem and copied the file at that point. My apologies. The pubspec.yaml for my own project is currently as follows:

name: xxxxxx
description: A new Flutter project.

version: 1.0.0+1

environment:
  sdk: ">=2.6.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2

  pdf: ^1.11.1
  path_provider: ^1.6.5
  flutter_full_pdf_viewer: ^1.0.6
  flutter_email_sender: ^3.0.1
  firebase_core: ^0.5.0+1
  cloud_firestore: ^0.14.1+2
  firebase_auth: ^0.18.1+2

  provider: ^4.3.2+2
  flutter_spinkit: "^4.1.2"

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:

  uses-material-design: true
  assets:
    - assets/

In terms of code I have continued to experiment to try and isolate the problem and in fact created an entirely fresh project based on the official example on GitHub which is available here:

https://pub.dev/packages/firebase_core/example

This shows the same behaviour with the same error trying to build to the Android Simulator. It (and my own project) does build to iOS fine.

The code for that, including initialisation is as follows:

            children: <Widget>[
              RaisedButton(
                  onPressed: initializeDefault,
                  child: const Text('Initialize default app')),
              RaisedButton(
                  onPressed: initializeSecondary,
                  child: const Text('Initialize secondary app')),
              RaisedButton(onPressed: apps, child: const Text('Get apps')),

            ],
          ),
        ),
      ),
    );
  }
}

And my pubspec.yaml for test project is:

name: fbasetest

This produces the same error as before i.e.:

As per my original post I can see that line of code in the FlutterFirebaseCorePlugin (line 92 in the plugin, line 4 in the snippet below):

private Task<Map<String, Object>> firebaseAppToMap(FirebaseApp firebaseApp) {
return Tasks.call(
cachedThreadPool,
() -> {
Map<String, Object> appMap = new HashMap<>();
Map<String, String> optionsMap = new HashMap<>();
FirebaseOptions options = firebaseApp.getOptions();
      ………..}

I have little knowledge of Java so can't really see if there is a problem there or if it is some sort of version conflict. I believe everything is as up to date as possible.

For completeness I have run flutter doctor again with the following result:

LeapingSwan commented 4 years ago

Hi TahaTesser,

Thanks for trying that.

First to confirm I have run Pub Cache repair and flutter clean before doing new builds.

Since the same code produces the error for me I believe it may be something to do with my setup, although everything else works fine. Since it works for iOS I think it's a problem with something in the Android setup. Could you please confirm what Android and Java JDK you used? Mine are as shown in the flutter doctor output (copied again below) so any differences you can see would be appreciated or if you can give me a print of your own flutter doctor I can try and match that.

Thanks

Hey @LeapingSwan. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

LeapingSwan commented 4 years ago

Hi, this issue is still unresolved for me.

I have compared the flutter doctor outputs but can see no difference (very minor differences on JDK release numbers but same version). I have tried updating to Android Studio 4.1 but that did not help so really at a loss. I'm not sure what additional information I could supply to give greater insight. On one level, as no one else seems to be having this problem, it looks like some sort of problem with my Android set up but I can't identify what. On another level the error reporting is taking me to a line of code in the Java update (as reported in my earlier comments) that does not seem to work though I can't see why (again not a Java expert by any means). I could really do with getting to the bottom of this as currently I cannot build for Android when I am using Firebase Core. It does work fine without Firebase Core.

Is there anyway to get this resolved?

I have the same problem. it is ok on iOS but on android keep showing this error Execution failed for task ':firebase_core:compileDebugJavaWithJavac'.

Could not resolve all files for configuration ':firebase_core:debugCompileClasspath'. Could not find lifecycle-runtime-2.0.0.jar (androidx.lifecycle:lifecycle-runtime:2.0.0). Searched in the following locations: https://dl.google.com/dl/android/maven2/androidx/lifecycle/lifecycle-runtime/2.0.0/lifecycle-runtime-2.0.0.jar

Possible solution:

after I upgrade my flutter on beta channel to Flutter 1.25.0-8.1.pre • channel beta • https://github.com/flutter/flutter.git Framework • revision 8f89f6505b (12 days ago) • 2020-12-15 15:07:52 -0800 Engine • revision 92ae191c17 Tools • Dart 2.12.0 (build 2.12.0-133.2.beta)

I am also getting the same problem. Did anyone resolved it already ? Please suggest.

LeapingSwan commented 3 years ago

Hi @balajijayabal,

Because of this issue I have been focusing on the iOS version of my App and doing my development there, hoping that an update of Android Studio might solve this problem at some point. I have however just tried the Android simulator to see if it's still there.

I tried initially without an update to Android Studio and got a string of errors where some files were not being found. I took a look at the suggested possible solution that @mohamadhadibi suggested and this did seem to refer to Mavern files as indicated in that documentation and the error messages I was getting at that point. I can't pretend I understand yet how to apply that documentation to my situation and will either have to hope that someone with more knowledge can more specifically explain how to use that or when I can I'll have to spend some time trying to understand it.

However before going any further I did an Android Studio update to the latest version as of today (not the Beta channel version) and now I'm back to a similar problem as posted in my original message i.e the error I get is:

/Users/[xxxxxxxxx]/.asdf/installs/flutter/1.12.13+hotfix.7-stable/.pub-cache/hosted/pub.dartlang.org/camera-0.5.8+11/android/src/main/java/io/flutter/plugins/camera/CameraPermissions.java:36: error: cannot find symbol (String errorCode, String errorDescription) -> { ^ symbol: method metafactory(Lookup,String,MethodType,MethodType,MethodHandle,MethodType) location: interface LambdaMetafactory Fatal Error: Unable to find method metafactory

FAILURE: Build failed with an exception.

Note though that this relates to Camera permissions and not firebase. I have added in camera permissions since initially raising this post so at least initially it seems to be tripping on that rather than firebase. Both work fine on the iOS version.

If anyone can suggest anything specific for me to try and solve this problem I'm happy to give it a go.

Thanks

Stephen

Hi @LeapingSwan, I faced with exact same issue. Try to update the Android Gradle plugin. This helped me :) 1) open /android folder through Android Studio 2) you would see something like that, click update. Screen Shot 2021-03-15 at 10 13 43 PM

I'm facing the same issue, but works on one mac and doesn't on another.

Hey @LeapingSwan, have you tried this suggestion?

LeapingSwan commented 3 years ago

Hi @russellwheatley yes I have tried this, making sure all plugins are fully up to date but no success.

In fact since my original post I had a major laptop crash when updating to Big Sur OS with the result that I have completely re-built the laptop software and re-installed Flutter/ Android Studio etc. I brought the project across from a backup but only the code etc. - all the platforms were newly installed on the rebuild a few weeks ago and updated again this morning and I'm still getting exactly the same error on Android although building to iOS is fine. As originally reported that was also true on the official example. That leaves me thinking there is something in my project settings (across all projects) but no idea where to look for that.

Thanks

Hi @LeapingSwan I am facing the same issue. I have installed Android Studio over snap and I am gonna try to install it as standalone. Did you try installing it without Snap too?

I have tried it and it did not help.

I have tried it and it did not help.

...and i also tried reinstalling flutter to a standalone installation instead of snap. same result.

LeapingSwan commented 3 years ago

Hi @ronky , I have not used Snap at all. I have simply downloaded Android Studio .dmg (I am working on a Mac) and installed from there.

One thing to make clear my initial install of Android Studio, probably about a year ago, worked fine and built without a problem. I was mainly working on iOS so not sure when the problem was actually introduced. It may have been when I started adding some of the plugins or it may have been after an update of some of my software platforms.

ronky commented 3 years ago

@LeapingSwan the only workaround my colleague found so far, is let the app run in the web browser. But that poses other problems down the road... Any successes on your side?

LeapingSwan commented 3 years ago

Hi @ronky yes running in a browser would not do it for me - really need to test and publish on the simulator/ device but currently can't build for Android at all.

It's clearly not just me experiencing this but presumably most people are not having this problem or it would be a much bigger issue and get attention as it is a complete stop for those of us having to deal with it.

Really not sure what the magic difference is and apart from responses on this thread I seem to be waiting for it to get fixed as part of an update of Flutter but don't know when that might be. For the time being I keep working on iOS but will need to publish to Android eventually.

@markusaksli-nc why did you remove the 'Needs Attention' label as this is still unresolved and needs a solution. Are you able to get someone suitable to look at it?

ronky commented 3 years ago

@LeapingSwan I completely reinstalled Ubuntu and set up the environment from scratch and... it runs. So it must be some kind of a config issue and unrelated to the firebase core I guess.

LeapingSwan commented 3 years ago

Hi @ronky great to hear you have got past this issue.

I'm not using ubuntu (unless it's somewhere in the background of something else I have installed - I'm a self taught part time developer so don't really have great depth to areas outside where I have needed to focus). My development environment is a MacBook Pro. As mentioned in an earlier post I have completely rebuilt the machine a few weeks ago for a different reason and freshly installed flutter from scratch but that has not worked for me.

I have tried again this morning (there is a Flutter upgrade in waiting but I have not done that yet as want to get something else working in my app before I make any changes to the environment at all) and it has still not worked for Android. The error I get is as follows:

Execution failed for task ':camera:compileDebugJavaWithJavac'.

Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation.

That is falling over at the same point but the message seems slightly different so I'll explore that in due course. I do need to keep focusing on the iOS version at the moment. Once I have that completed I'll come back to getting g the Android version working.

Thanks

Stephen

russellwheatley commented 3 years ago

Hey @LeapingSwan, I don't believe your error is an issue with the Flutterfire library. I did a quick google search of your error and up popped this thread on StackOverflow with the exact error you pasted:

Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation.

In a nutshell; you need to either install Java developer kit (JDK) and add to your path, or you need to make your existing JDK path visible on your path. Or update your gradle setup in your android project to point to your JDK. Either way, there are plenty of resources online to help you get setup. Hope this helps.

LeapingSwan commented 3 years ago

Hi @russellwheatley , thanks for your comments.

As per my earlier posts the JDK was installed and Flutter doctor was showing everything was ok. Like you I did at points suspect that there was a problem with the set up as I have mentioned before but I could not find what it was and as per one of my original posts the error that was being thrown up could be traced back to failing at a line of code in the Java plugin (so it was seeing and accessing the plugin). I'm not sure that thread you linked to, whilst similar, actually related to the same issue. Because I did suspect it might be a set up issue I spent many hours looking at that possibility and following up various pieces of guidance on how to install the Java plugin and setup Android Studio. But this at least started off as seeing the Java code and failing. As per my original post:

"I believe I have tracked this back to the following line of code line 92 (the fourth line here) in the Java plugin referred to, FlutterFirebaseCorePlugin:

private Task<Map<String, Object>> firebaseAppToMap(FirebaseApp firebaseApp) { return Tasks.call( cachedThreadPool, () -> { Map<String, Object> appMap = new HashMap<>(); Map<String, String> optionsMap = new HashMap<>(); FirebaseOptions options = firebaseApp.getOptions(); ………..}"

The good news is that I did an update of Flutter this morning and an update of Android Studio recently (to 4.2) & updated the JDK, as well as checking again that all of my dependencies are up to date, and it now builds fine. Really not sure which of those updates fixed the problem but I do seem to have got past it. Perhaps this has fixed whatever problem I had with setup or there has been an unintentional fixe via the plugin.

For anyone else coming to this thread I have posted below my flutter doctor so it can be seen what the status was when it did work.

Thanks for your help.
