Protobuf duplicate class issue

[GieMik8]

Hello, I am trying to implement your library into our project and getting some troubles.

Protobuf issue:

...of course, error code continues much further.

Have tried to look for a workaround, but nothing works out perfectly.

Have tried to exclude sub dependency:

    implementation ('org.dpppt:dp3t-sdk-android:0.2.6') {
        exclude group: "com.google.protobuf", module: "protobuf-javalite"
    }

And at least it helps to build the project. However, when invoking initialize method error happens:

We are using firebase config and firebase inappmessaging in our project.

Is there any way to make it work?

Any help appreciated.

[jeffallen]

I was not able to repro this.

I made a new Hello World project, targeting API level 23 (see #16 for why).

I added this to my app/build.gradle:

    def dp3t_sdk_version = '0.2.6'
    implementation "org.dpppt:dp3t-sdk-android:$dp3t_sdk_version"

I went to the layout editor and gave the Hello World text box the id hello. I added this to my MainActivity.kt:

        setContentView(R.layout.activity_main)
        hello.text = org.dpppt.android.sdk.BuildConfig.VERSION_NAME;

I got the error mentioned in this SO posting: https://stackoverflow.com/questions/49891730/invoke-customs-are-only-supported-starting-with-android-0-min-api-26

I fixed it by adding this in app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

I was then able to get a minimal app running that linked against the DP-3T JAR file. (I was also able to call DP3T.init() as well, though you'll need to figure out how to get the PublicKey that it needs. See the calibration app.)

I have managed to reproduce the issue in demo calibration app project.

Building the project starts to fail when adding implementation 'com.google.firebase:firebase-inappmessaging-display:19.0.6' in app dependencies.

Not pointing fingers here, but how is it a DP-3T problem that when you add firebase to your app, it starts to fail?

Good point @jeffallen but in my case I have included DP-3T into our project later (we are using Firebase for quite some time). It would be great to use both libraries in our project. Firebase is important for most apps.

Exclude the protobuf group when adding the firebase dependency. This worked for me.

implementation ("com.google.firebase:firebase-config:19.2.0",{ exclude group: 'com.google.protobuf' })

[jaafarnejm]

This error means that you are importing two packages that use Protobuf for your project, one of them has a distribution that's conflicting with the other.

If you encountered this problem on Flutter, you can reconsider the version number of your dependencies in pubspec.yaml, and replace "any" by an exact version number.
For example, under "dependencies:" change:

barcode_scan: any

To:

barcode_scan: ^2.0.0

I hope I helped.
