I wish this helpful for you TLDR; you need to extend DisplayLeakService
https://github.com/square/leakcanary/wiki/Customizing-LeakCanary#uploading-to-a-server
public class LeakUploadService extends DisplayLeakService {
  @Override protected void afterDefaultHandling(HeapDump heapDump, AnalysisResult result, String leakInfo) {
    if (!result.leakFound || result.excludedLeak) {
      return;
    }
    if (result.leakFound) {
      uploadLeakToServer(result, leakInfo);
    }
  }

  private void uploadLeakToServer(AnalysisResult result, String leakInfo) {
    // TODO Upload result to server
  }
}
public class LeakUploadService extends DisplayLeakService {

  @Override protected void afterDefaultHandling(HeapDump heapDump, AnalysisResult result, String leakInfo) {
    if (!result.leakFound || result.excludedLeak) {
      return;
    }
    if (result.leakFound) {
      uploadLeakToServer(result, leakInfo);
    }
  }

  private void uploadLeakToServer(AnalysisResult result, String leakInfo) {
    Client bugsnagClient = new Client(getApplication(), "YOUR_BUGSNAG_API_KEY", false);
    bugsnagClient.setSendThreads(false);
    bugsnagClient.beforeNotify(error -> {
      // Bugsnag does smart grouping of exceptions, which we don't want for leak traces.
      // So instead we rely on the SHA-1 of the stacktrace, which has a low risk of collision.
      String stackTraceString = Logs.getStackTraceString(error.getException());
      String uniqueHash = Strings.createSHA1Hash(stackTraceString);
      error.setGroupingHash(uniqueHash);
      return true;
    });

    MetaData metadata = new MetaData();
    metadata.addToTab("LeakInfo", "LeakInfo", leakInfo);
    bugsnagClient.notifyBlocking(result.leakTraceAsFakeException(), Severity.ERROR, metadata);
  }
}
public class DebugExampleApplication extends ExampleApplication {
  @Override protected void installLeakCanary() {
    RefWatcher refWatcher = LeakCanary.refWatcher(this)
      .listenerServiceClass(LeakUploadService.class);
      .buildAndInstall();
  }
}

how to use leakcanary, how to add leakcanary as a jar to build a apk with .mk file

hop of those help? LeakCanary is not just a JAR - it contains not only the java code, but resources too (png's for example). If you are using ANT, then the only thing you can do is to include LeakCanary as a library project. But I strongly recommend switching to gradle. Because android development team is not going to support importing any library which is not just jar in any user-friendly way in the nearest future (because gradle is priority). And importing as library projects is a painful procedure, which get's more painful when it sometimes comes to including library's dependencies also as library projects. I've done it by hand long ago only because the client used eclipse with ant for big project for ages. Generally, you must do the following:
Obtain sources: source code, assets, resources... Investigate LeakCanary's dependencies. You may look "POM Object Model" here. For dependencies, which have more than just java code, you'll need to include them as library again. For others, just download them as jar. For assets (fonts, for example) there are an extra step: you must copy them to the project you are working on or you'll get a resource not found exception.

Reading LeakCanary Log

I think the issue was by ths following , This library is pure awesomeness and saved me a lot of headache. In many cases it shows exactly where the leak is. But in your case the leak occurs on your activity class itself so LeakCanary tells you from which class. You're probably registering the activity as a listener to another class and forget to unregister it. My advice is that you search in your activity class references to this. Each one of those can be a potential leak.

this one helps. I believe to have successfully installed LeakCanary. ,
Does my application class need to be explicitly called?

How to verify LeakCanary is working properly - We cannot see LeakCanary in logging

To fix this issue I have a legacy project which , you don't need to add
implementation 'com.squareup.leakcanary:leakcanary-android:1.6.3'
debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.3'
@Override
public void onCreate() {
    super.onCreate();

    if (LeakCanary.isInAnalyzerProcess(this)) {
        // This process is dedicated to LeakCanary for heap analysis.
        // You should not init your app in this process.
        return;
    }
    LeakCanary.install(this);

    // rest of your init code
}
