qt 6.8 EmailSender + activity() is not public in QtNative + cannot be accessed from outside package

Parvathy2020

Hi,

I am trying to update my qt version from 6.5.3 -> 6.8.0 LTS.

When I try to build my Qt application with android (android_arm64_v8a), i get the below error:

*> Task :compileDebugJavaWithJavac FAILED
......\EmailSender.java:43: error: activity() is not public in QtNative; cannot be accessed from outside package
Intent intent = ShareCompat.IntentBuilder.from(QtNative.activity()).getIntent();
^
......\EmailSender.java:58: error: activity() is not public in QtNative; cannot be accessed from outside package
Uri contentUri = FileProvider.getUriForFile(QtNative.activity(), authority, contentFile);
^
2 errors
FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':compileDebugJavaWithJavac'.

Compilation failed; see the compiler error output for details.*

Please guide with a solution ?
Note : It is seen that similar issue is already reported by some other user. But there is no solution available

@Parvathy2020 Compare your dependencies with https://doc.qt.io/qt-6.5/android.html

Hi @jsulm , Dependencies are updated as per https://doc.qt.io/qt-6/android.html
But still I am getting the same error.

Not able to identify what is the root cause of the issue. package v4.x.x;

Please find the source code ,

    String[] recipients = { recipient };

    Intent intent = ShareCompat.IntentBuilder.from(QtNative.activity()).getIntent();
    intent.setAction(Intent.ACTION_SEND);

    intent.setData(Uri.parse("mailto:"));
    intent.putExtra(Intent.EXTRA_EMAIL, recipients);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, body);

    String authority = context.getPackageName() + ".fileprovider";

    if (attachmentPathString.length() > 0)
    {

        try
        {

    }

    intent.setType("message/rfc822");

    Intent.createChooser(intent, chooseEmailMEssage);

    Log.d(TAG, "sendEmailIntent - end");

    return intent;
}

}

@Parvathy2020 said in qt 6.8 EmailSender + activity() is not public in QtNative + cannot be accessed from outside package:

public class EmailSender extends org.qtproject.qt.android.bindings.QtActivity

thats no longer a valid import in Qt6, QtActivity was removed, afaik.

I was told you have to extend the base activity now a days:

import android.app.Activity;
import android.os.Bundle;

public class EmailSender extends Activity {

Not sure how accurate that is. I was in the process of transitioning to Qt6 but other projects triggered a priority interrupt and it's on hold right now. My experience is incomplete :(

Okey @J-Hilk , Tried by extending Activity, but it is not helping.

Due to some reason not able to access the activity().
