Steps to Reproduce

This code snippet returns null only when selecting image from Google Photos:

await ImagePicker().getImage(
      source: ImageSource.gallery,
      imageQuality: 70,
      maxWidth: 2048,
      maxHeight: 2048,
    );

And I get this message in log cat:

E/UpdateManager.Error( 5083): com.google.android.play.core.install.InstallException: Install Error(-3): The API is not available on this device. (https://developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE)

    Hi @DomantasZav
    Can you please try a different device? Make sure you're using the latest stable `image_picker: ^0.6.7+22
    I can't reproduce it on a Oneplus or Realme device

    code runnable sample 
    import 'package:flutter/material.dart';
import 'package:image_picker/image_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      theme: ThemeData.dark(),
      home: Home(),
    );
  }
}

class Home extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Material App Bar'),
      ),
      body: Center(
        child: Container(
          child: Text('Hello World'),
        ),
      ),
      floatingActionButton: FloatingActionButton(
        child: Icon(Icons.add),
        onPressed: () async {
          final file = await ImagePicker().getImage(
            source: ImageSource.gallery,
            imageQuality: 70,
            maxWidth: 2048,
            maxHeight: 2048,
          );

          print(file.path);
        },
      ),
    );
  }
}

    Printing path of the picked file

    Found the issue:
    It only happens on android devices and if launchMode in AndroidManifest is set to singleInstance
    The error I provided was caused by something else.
    So there is no indication of error. It just returns null.

    I've been investigating the issue thoroughly. These are my findings.

    The issue occurs when the following conditions are met:

    • The activity in the Android manifest runs in launchMode: singleInstance,
    • The Intent.GET_CONTENT intent is used to open the native image picker application,
    • The user selects a file from Google Photos.

    I found that when these steps are taken, the onActivityResult function is called with a result code of RESULT_CANCELED instead of RESULT_OK.

    I created a basic native Android app to test whether this also happens on Android-only, as it could potentially be caused by the way Flutter uses the activities. The native app contains the basic activity from the template. On clicking the FAB, I start the image picker activity using the Intent.ACTION_GET_CONTENT intent.

    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);

    This all goes well. Then I update the manifest to use android:launchMode="singleInstance". Now, when opening the file picker and selecting a file from Google Photos, I receive a result code RESULT_CANCELED.

    This leads me to believe that this issue is a bug in the Android Image Picker.

    This leads me to believe that this issue is a bug in the Android Image Picker.

    Based on further investigation, it looks like this is expected behavior rather than a bug, as described here. If the calling app forbids other activities it its task, then it can't get results from other activities.

    We can document this in the plugin's README to help avoid people being surprised by it.
