Simple RxJava2 binding for Android BroadcastReceiver

ReactiveBroadcast

Simple RxJava2 binding for Android BroadcastReceiver

Usage

RxBroadcastReceivers.fromIntentFilter(context, intentFilter)
        .subscribe(intent -> {
            // do something with broadcast
        });

What's new:

• 1.0.2 library utilizes Context#registerReceiver(BroadcastReceiver, filter, broadcastPermission, scheduler) method when subscription occurs on background thread looper.
• 1.0.5 fixed problem with manifest merger.

Download

To use library with Gradle

dependencies {
  implementation 'com.github.karczews:rx2-broadcast-receiver:1.0.6'
}

or using Maven:

<dependency>
    <groupId>com.github.karczews</groupId>
    <artifactId>rx2-broadcast-receiver</artifactId>
    <version>1.0.6</version>
</dependency>

rxbroadcastreceiver's Issues

DeadSystemException during dispose

I'm seeing small amount of DeadSystemException on Android TV devices.
Most probably device is going to power off and VM is dying already when RxBroadcastReceiver is trying to dispose.

Android: 8.0.0

I'd expect that unregistering BroadcastReceiver should be wrapped and onError emitted (or swallowed?)

RxJava3 Support

Thanks for this cool library! Are you planning to support RxJava3 anytime?

Maven Local Publishing

To add some additional possibilities for testing the library, we could add publishing to the local repository. Nothing really sophisticated.

We could use android-maven-publish Gradle plugin for it. It would involve adding it to the main build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.dicedmelon.gradle:jacoco-android:0.1.1'
        classpath 'digital.wup:android-maven-publish:3.3.0' //<---- this one
    }
}

To keep everything inline with the existing mvn-publish configuration we could add a script:
gradle-mvn-local.gradle that would contain the configuration:

apply plugin: 'digital.wup.android-maven-publish'

publishing {
    publications {
        mavenAar(MavenPublication) {
            from components.android
            groupId GROUP
            artifactId POM_ARTIFACT_ID
            version "${VERSION_NAME}-LOCAL"
        }
    }
}

This would produce artifacts in the .m2/ directory. For example for the 1.0.5-SNAPSHOT it would be 1.0.5-SNAPSHOT-LOCAL

Need maven version update

The latest versions are unavailable at Maven, but Jetpack often fails with connection errors

Manifest merger fails with error.

Hey. My app's manifest contains following lines:

• android:allowBackup="false"
• android:supportsRtl="false"

And it can't compile because of these issues:

Now I use tools:replace="android:allowBackup, android:supportsRtl" as a quick workaround but as I understand that's not the desired behavior.

Could you please fix?

getApplicationContext() error when instrumentation testing a service that uses a broadcast receiver

Hi there,

I have a service that uses a broadcast receiver (RxBroadcastReceiver) for communication. While testing this service with junit4 in an instrumentation test I get an getApplicaitonContext() Nullpointer exception while trying to register the receiver. Is there any advice or help to have the test working?
Any help would be highly appreciated.
