[losciur]

Hi,
I try the plugin with capacitor 3 and I got this error in Android Studio:

What can I do?

thanks

Please post the full code of MainActivity,java

[losciur]

That is the full code...
In the previous image I just cut the first line where there is my package name...

The app is created with ionic angular capacitor 3.
Everything works fine except firebase.

I repost here MainActivity.java:

package it.piemonte.arpa.meteo3RTest;


  import com.getcapacitor.BridgeActivity;
  
  import com.getcapacitor.community.firebaseanalytics.FirebaseAnalytics;

public class MainActivity extends BridgeActivity {

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Initializes the Bridge
    this.init(
      savedInstanceState,
      new ArrayList<Class<? extends Plugin>>() {

        {
          // Additional plugins you've installed go here
          // Ex: add(TotallyAwesomePlugin.class);
          add(FirebaseAnalytics.class);
        }
      }
    );
  }
}

import android.os.Bundle;
import com.getcapacitor.BridgeActivity;
import com.getcapacitor.Plugin;
import com.getcapacitor.community.firebaseanalytics.FirebaseAnalytics;
import java.util.ArrayList;

Add these imports in MainActivity.java

This is a duplicate of #94, closing.

[losciur]

Thanks for the help!
Mixing what you suggest and what in capacitor documentation and in #94 I think that the better solution is:

  import android.os.Bundle;
  import com.getcapacitor.BridgeActivity;
  import com.getcapacitor.community.firebaseanalytics.FirebaseAnalytics;


public class MainActivity extends BridgeActivity {

  @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

        registerPlugin(FirebaseAnalytics.class);
     }

}

Maybe you may add this lines in the documentation of this plugin, because the lines you suggest are deprecated.

[brownoxford]

The capacitor documentation indicates that the registerPlugin call is not needed for plugins installed via NPM, which is the case for the firebase-analytics plugin. You only need to call registerPlugin if you have local custom plugins that you developed for your app and are not installing from NPM.

[losciur]

You're right about the capacitor documentation,
but if I leave the code you suggest:

import android.os.Bundle;
import com.getcapacitor.BridgeActivity;
import com.getcapacitor.Plugin;
import com.getcapacitor.community.firebaseanalytics.FirebaseAnalytics;
import java.util.ArrayList;

public class MainActivity extends BridgeActivity {

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Initializes the Bridge
    this.init(
      savedInstanceState,
      new ArrayList<Class<? extends Plugin>>() {

        {
          // Additional plugins you've installed go here
          // Ex: add(TotallyAwesomePlugin.class);
          add(FirebaseAnalytics.class);
        }
      }
    );
  }
}

I got this (Android Studio 4.2.1):

On the other side, when I install any official capacitor plugins via npm I don't have to modify the ManiActivity.java file in Android Studio (I don't know why).

Thank you very much for your work and this explanation words, I'm very happy to try to understand something more in plugin.
