Playstore error: App Bundle contains native code, and you've not uploaded debug symbols

Question

When I want to release a new flutter app bundle to the Playstore. I get this error: "This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug." I can't find any way to fix this. I'm new with flutter and releasing app's and getting a bit desperate... Any help would be fantastic.

When I add "android.defaultConfig.ndk.debugSymbolLevel = 'FULL'" (on line 1) to the app/build.gradle as suggested in https://developer.android.com/studio/preview/features#native-crash-symbolization. I get This error in the Android studio terminal. I use this command "flutter build appbundle".

Error in Terminal: FAILURE: Build failed with an exception.

• Where: Build file 'C:\Users\filip\AndroidStudioProjects\ehbo\android\app\build.gradle' line: 1

• What went wrong: A problem occurred evaluating project ':app'.

Answer 1

Reproduce next steps and this warning will disapear

1. Go to [YOUR_PROJECT]\app\build\intermediates\merged_native_libs\release\out\lib

For some the path might be [YOUR_PROJECT]\build\app\.... and not [YOUR_PROJECT]\app\build\.... like mentioned above.

note that 3 folders exist inside

• arm64-v8a
• armeabi-v7a
• x86_64

2. Select this 3 folder and create a .zip file. Name doesn't matter.

[PLEASE NOTE THAT I HAVEN'T COMPRESSED THE ./lib FOLDER]

3. Upload this new *.zip file as Symbol File.

Answer 2

If talking about Flutter, looks like the Flutter team needs to change some source files for the NDK, because it does not see where from to generate debug symbols.

Here is an issue thread: https://github.com/flutter/flutter/issues/60240

Setup steps are so:

• Pre-condition: Intall Android studio 4.1+ and Gradle 4.1+

1. Install NDK (Side by Side) in SDK manager

2. Write path to NDK in local.properties

3. Add in app/build.gradle (last line) android.buildTypes.release.ndk.debugSymbolLevel = 'FULL'

Answer 3

Before you can upload debug symbols files, you must be using Android Gradle plugin version 4.1 or higher.

Looks like it will come only with Android Studio 4.1, because I can only get Gradle 4.0.0 automatically now.

So I suggest you to return classic Play console and it will let you through :)

UPDATE: So just use an updated Gradle and add NDK debug symbols to the build now

Answer 4

The Answer was given by Shakle will be not useful as per the following message on Play Console.

The old version of Play Console will be discontinued from November 2, 2020 You’re already using the new Play Console, so you don’t need to do anything. A few features are going away if you want to check them one last time.

It's just a warning, nothing else. Just go ahead.

If you don't want any warning, Go to this link and follow the steps:

https://support.google.com/googleplay/android-developer/answer/9848633?hl=en

You can use the new version of the play store as it is.

Answer 5

you can make these zip file by go to build\app\intermediates\merged_native_libs\release\out\lib inside your Flutter project

and compress the folders into symbols.zip, now upload it into the google play console

Answer 6

I had a similar problem. What really helped me:

1. Make sure your Android Gradle plugin version is 4.1 or later.
2. Install NDK (Side by Side) in SDK manager.
3. Install CMake in SDK manager.
4. Add

    ndkVersion <ndkVersion>
    ndk {
      debugSymbolLevel 'FULL'
    }

to app/build.gradle

My final build.gradle:

...
android {
  compileSdkVersion 30
  defaultConfig {
    applicationId "com.example.app"
    minSdkVersion 21
    targetSdkVersion 30
    versionCode 28
    versionName "1.0.59"
    ndkVersion "23.1.7779620"
    ndk {
      debugSymbolLevel 'FULL'
    }
  }
  buildTypes {
    release {
      minifyEnabled true
      shrinkResources true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }

  configurations {
    compile.exclude group: 'com.google.zxing'
  }
}
...

I hope this will help you and save you time

If you want to solve this warning error: This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug. Make sure also to install CMake

This will happen if your gradle version is higher than 4.0 Place this code into your build.gradle file

android {
compileSdkVersion 28
defaultConfig {
    applicationId 'com.example.myproject'
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "1.0.0"
    ndk {
        debugSymbolLevel 'FULL'
    }
}

Answer 8

Instead of creating and uploading zip files, you can include the following to your app\build.gradle file:

buildTypes {
    debug { 
        // This is just here for local testing and is optional.
        firebaseCrashlytics { 
            nativeSymbolUploadEnabled true
            unstrippedNativeLibsDir file("build/app/intermediates/merged_native_libs/debug/out/lib")
        }
        ndk {
            debugSymbolLevel 'SYMBOL_TABLE'
        }
    }
    release {
        // ..
        firebaseCrashlytics { // Insert this
            nativeSymbolUploadEnabled true 
            unstrippedNativeLibsDir file("build/app/intermediates/merged_native_libs/release/out/lib")
        }
        ndk {
            // replace with 'FULL' if you need more info,
            // but note that it will increase the file size of your appbundle dramatically.
            debugSymbolLevel 'SYMBOL_TABLE'
        }
    }
}

Here is some documentation for reference: https://firebase.google.com/docs/crashlytics/ndk-reports#upload-symbols-external-dependencies

And if you're unclear about how to set up automatic uploading of native symbols, try adding this:

buildTypes { ... } // Your build types from the above snippet.

tasks.whenTaskAdded { task ->
    if (task.name.startsWith('assemble') && task.name != "assembleReleaseAndroidTest"
            && task.name != "assembleDebugAndroidTest") {
        String taskName = "uploadCrashlyticsSymbolFile" + task.name.substring('assemble'.length())
        task.finalizedBy taskName
        doFirst {
            println "Running Gradle task '$taskName'..."
        }
    }
}

More info for building gradle tasks here: https://docs.gradle.org/current/userguide/tutorial_using_tasks.html

Also, ensure that you have NDK and CMAKE installed in your IDE's SDK Manager.

Hope that helps!

Simple approach, go to \build\app\intermediates\merged_native_libs\release\out\lib , you will find 3/4 folders , zip those , upload this ZIP from release option ( upload Symbol File ). Warning will be gone after bundle review.

Answer 10

For fixing it in the Visual Studio Code: you should first download the NDK from the android's website.

• Extract the zip file to a folder named ndk and place it under your - already installed - Android SDK folder. Like this: Android/sdk/ndk

• Then open app/build.gradle.

• Under the Android section. Add ndkPath property as follows: ndkPath = <ndk-dir>

app/build.gradle ndkPath property

• At the end of app/build.gradle add android.buildTypes.release.ndk.debugSymbolLevel = 'full'

• The next appbundle, built by flutter build appbundle command should not give any errors on the play store about native debug symbols.

Answer 11

I just upgraded ndk from 21.4.7075529 to 22.1.7171670, and now I get the debug symbols.

I'm using com.android.tools.build:gradle:7.1.1 and React Natvive 0.69 BTW.

Answer 12

I have the exact same issue.

Possible solutions:

1. Use the Google classic Play console
2. Gradle 4.1 is now released with Android Studio 4.1

Answer 13

Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.

You have to add it in gradle.properties not build.gradle

Answer 14

I was able to get Flutter to build native debug symbols using Android Gradle Plugin (AGP) 4.1.0, installing corresponding NDK version and adding the appropriate config to android/app/build.gradle on macOS (but it should also work on Windows/Linux).

0. Optional: Run flutter build appbundle and take note of the .aab file size
1. Check what version of AGP you're using in android/build.gradle by looking in dependencies e.g. com.android.tools.build:gradle:4.1.0 is 4.1.0
2. Check which version of NDK you need. Assuming your AGP is 4.1.0 the NDK version you want to install is 21.1.6352462 (for other AGP versions check mappings here)
3. Install specific NDK version using Android Studio. Alternatively you can use sdkmanager and the CLI: $ANDROID_HOME/tools/bin/sdkmanager --install "ndk;21.1.6352462"
4. In android/app/build.gradle, under android.defaultConfig add ndk { debugSymbolLevel 'FULL' } aka set android.defaultConfig.ndk.debugSymbolLevel = 'FULL' as per this
5. Run flutter build appbundle. The .aab should now contain native debug symbols and be larger than the previous build in step 0

Troubleshooting: If you get any errors around CMake I didn't explicitly install it but you might need to, especially if you're using Windows, and you can do so using Android Studio.

Answer 15

screenshot

My issue was this:

This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug.

Fix successfully just upload native debug symbols from the image reference directory shown.
