Trying to build my app (which has previously worked fine) after switching out a package. Now I'm getting the following:
/Users/rgb/Repositories/cadsys_member_app_flutter/android/app/src/main/java/com/example/member_app_flutter/Application.java:18: error: incompatible types: PluginRegistry cannot be converted to FlutterEngine
GeneratedPluginRegistrant.registerWith(registry);
^

^

location: class MainActivity
Note: /Users/rgb/Repositories/member_app_flutter/android/app/src/main/java/com/example/member_app_flutter/Application.java uses or overrides a deprecated API.
Here is my Application.java:
package net.xxx.app;
import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
public class Application extends FlutterApplication implements PluginRegistrantCallback {
#Override
public void onCreate() {
super.onCreate();
}
#Override
public void registerWith(PluginRegistry registry) {
GeneratedPluginRegistrant.registerWith(registry);
}
}
Haven't been able to find a solution, hope someone can shed some light on this issue.

I am trying to use the android_alarm_manager_plus package to schedule background tasks in flutter. In their documentation, they have added the Application class code for JAVA, which is as follows -
public class Application extends FlutterApplication implements PluginRegistrantCallback {
#Override
public void onCreate() {
super.onCreate();
AlarmService.setPluginRegistrant(this);
}
#Override
public void registerWith(PluginRegistry registry) {
GeneratedPluginRegistrant.registerWith(registry);
}
}
But I'm working on a kotlin based project (without any knowledge of kotlin, I may add) and there is no documentation for this. I tried writing the kotlin counterpart to this code myself, but I'm still facing errors.
My Application.kt file -
package com.example.my_app;
import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.AndroidAlarmManager.AlarmService;
class Application : FlutterApplication(), PluginRegistry.PluginRegistrantCallback {
override fun onCreate() {
super.onCreate()
AlarmService.setPluginRegistrant(this);
}
override fun registerWith(registry: PluginRegistry?) {
registry?.registrarFor("GeneratedPluginRegistrant");
}
}
The errors -
Application.kt: (7, 27): Unresolved reference: AndroidAlarmManager
Application.kt: (15, 9): Unresolved reference: AlarmService
You do not need to add this Java/Kotlin code. That's for the old Android embedding. Note the "DEPRECATED" here in the title: https://github.com/fluttercommunity/plus_plugins/tree/main/packages/android_alarm_manager_plus#flutter-android-embedding-v1-deprecated
I'm using firebase_messaging in my flutter application.
To handle background messages with firebase messaging in pub they suggested to create new Application.java file and replace java file name in AndroidManifest file.
In my application i'm using kotlin and i already implemented some native code in MainActivity.kt
So how to write this code in kotlin.
package io.flutter.plugins.firebasemessagingexample;
import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService;
public class Application extends FlutterApplication implements PluginRegistrantCallback {
#Override
public void onCreate() {
super.onCreate();
FlutterFirebaseMessagingService.setPluginRegistrant(this);
}
#Override
public void registerWith(PluginRegistry registry) {
GeneratedPluginRegistrant.registerWith(registry);
}
}
it is mandatory to replace MainActivity to Application in AndroidManifest file?
Here is the working background notification kotlin code:
package com.example.yourapp
import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService
class Application : FlutterApplication(), PluginRegistrantCallback {
override fun onCreate() {
super.onCreate()
FlutterFirebaseMessagingService.setPluginRegistrant(this);
}
override fun registerWith(registry: PluginRegistry?) {
io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
}
}
Here is the Kotlin code for the new firebase cloud messaging version:
package id.your.app
import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
import io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingBackgroundService
// import io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingPlugin
class Application : FlutterApplication(), PluginRegistrantCallback {
override fun onCreate() {
super.onCreate()
FlutterFirebaseMessagingBackgroundService.setPluginRegistrant(this)
}
override fun registerWith(registry: PluginRegistry?) {
// FlutterFirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingPlugin"))
}
}
Generated component of dagger couldn't find symbol of the kotlin classes even if there is no read lines on this component.

does your project use kapt?
If so, you can disable the cache of kapt.
Open your build.gradle file in the app module, and set the useBuildCache to false, and sync the Gradle.
Try to rebuild your code.
kapt {
useBuildCache = false
}
If everything goes fine, you can enable useBuildCache again.

I want to start using Robolectric and RoboGuice in my Android-Apps. While I make satisfactory progress using Robolectric I am stuck using RoboGuice. I created a small Android-App for experimenting. It is only one Activity, injecting a Button and setting its OnClickListener.
In the related Test-Class I want to Inject this Activity, to be able to test the Button. I tried a lot of things I found all over the internet, but none of these worked, so I give it a go here.
Here is some code:
MainActivity.java:
package com.example.TrialApp;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import roboguice.activity.RoboActivity;
import roboguice.inject.InjectView;
public class MainActivity extends RoboActivity implements View.OnClickListener {
#InjectView(R.id.main_LoginButton) private Button loginButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
loginButton.setOnClickListener(this);
}
#Override
public void onClick(View view) {
SharedPreferences.Editor editor;
if (view.getId() == R.id.main_Login_Button)
Log.i("Login-Button pressed... ", "");
}
}
CustomRobolectricTestRunner.java:
package com.example.TrialApp;
import com.xtremelabs.robolectric.RobolectricTestRunner;
import org.junit.runners.model.InitializationError;
import java.io.File;
public class CustomRobolectricTestRunner extends RobolectricTestRunner {
public CustomRobolectricTestRunner(Class testClass) throws InitializationError {
// defaults to "AndroidManifest.xml", "res" in the current directory
super(testClass, new File("TrialApp"));
}
}
MainActivity_Test.java:
package com.example.TrialApp;
import com.google.inject.Inject;
import com.xtremelabs.robolectric.Robolectric;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import static org.junit.Assert.assertNotNull;
#RunWith(CustomRobolectricTestRunner.class)
public class MainActivity_Test {
#Inject MainActivity mainActivity;
#Inject ClassWithoutAName classWithoutAName;
#Before
public void setUp() {
}
#Test
public void mainActivityShouldNotBeNull() {
assertNotNull(mainActivity);
}
#Test
public void classWithoutANameShouldNotBeNull() {
assertNotNull(classWithoutAName);
}
}
classWithoutAName is just a non-Activity-class with no content. I added just for injecting a non-Activity-class.
Running the Test-Class both tests fail giving the following errors:
java.lang.AssertionError
at com.example.TrialApp.MainActivity_Test.mainActivityShouldNotBeNull(MainActivity_Test.java:33) <8 internal calls>
at com.xtremelabs.robolectric.RobolectricTestRunner$1.evaluate(RobolectricTestRunner.java:288) <16 internal calls>
and
java.lang.AssertionError
at com.example.TrialApp.MainActivity_Test.classWithoutANameShouldNotBeNull(MainActivity_Test.java:38) <8 internal calls>
at com.xtremelabs.robolectric.RobolectricTestRunner$1.evaluate(RobolectricTestRunner.java:288) <16 internal calls>
Obviously something is missing. Injecting in MainActivity works fine, and the app is running.
Why is the same pattern of injecting dependencies in a Robolectric-Testclass not working? Where is the missing link?
Thank you
After reading some more articles and threads I found a partial solution. I still haven't found a way to inject UI-elements in a testclass, but I found out, how to inject non-UI-elements in a testclass. The trick is to implement a "RobolectricTestModule" extending the AbstractModule. The bindings made in the modules declared in the roboguice.xml are not present in the test-environment, so we need to declare the bindings for the test-environment in this extra-module. In the customized Testrunner we replace the DefaultRoboModule with the new RobolectricTestModule.
ClassWithoutAName.java:
package com.example.TrialApp;
public class ClassWithoutAName {
private String string;
public ClassWithoutAName(String string) {
this.string = string;
}
public String getString() {
return string;
}
}
ClassWithoutANameProvider.java
package com.example.TrialApp.GuiceModules;
import com.example.TrialApp.ClassWithoutAName;
import com.google.inject.Provider;
public class ClassWithoutANameProvider implements Provider<ClassWithoutAName> {
#Override
public ClassWithoutAName get() {
return new ClassWithoutAName("testString");
}
}
ClassWithOutANameModule.java
package com.example.TrialApp.GuiceModules;
import com.example.TrialApp.ClassWithoutAName;
import com.google.inject.AbstractModule;
public class ClassWithOutANameModule extends AbstractModule {
#Override
protected void configure() {
bind(ClassWithoutAName.class).toProvider(ClassWithoutANameProvider.class);
}
}
RobolectricTestModule.java
package com.example.TrialApp.GuiceModules;
import com.example.TrialApp.WeirdThings;
import com.google.inject.AbstractModule;
public class RobolectricTestModule extends AbstractModule {
#Override
protected void configure() {
bind(ClassWithoutAName.class).toProvider(ClassWithoutANameProvider.class);
}
}
CustomRobolectricTestRunner.java
package com.example.TrialApp;
import android.app.Application;
import com.example.TrialApp.GuiceModules.RobolectricTestModule;
import com.xtremelabs.robolectric.Robolectric;
import com.xtremelabs.robolectric.RobolectricTestRunner;
import org.junit.runners.model.InitializationError;
import roboguice.RoboGuice;
import java.io.File;
public class CustomRobolectricTestRunner extends RobolectricTestRunner {
public CustomRobolectricTestRunner(Class testClass) throws InitializationError {
// defaults to "AndroidManifest.xml", "res" in the current directory
super(testClass, new File("TrialApp"));
}
#Override
public void prepareTest(Object test) {
Application application = (Application) Robolectric.application;
RoboGuice.setBaseApplicationInjector(application, RoboGuice.DEFAULT_STAGE,
RoboGuice.newDefaultRoboModule(application), new RobolectricTestModule());
RoboGuice.getInjector(application).injectMembers(test);
}
}
Thats it for the non-UI-Elements.
