Okay finally found it, you have to make sure that your gradle.properties file contains this in order to have everything working with AndroidX:


android.enableJetifier=true
android.useAndroidX=true
org.gradle.jvmargs=-Xmx1536M

Please also make sure that you have those dependencies in your build.gradle:

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.2.0'
    }

I'll update the README this evening if I have some confirmations that it is working :)

Also a similar issue here.

The first time (after installing the plugin), I'm getting a silent-crash (only in logs):

MissingPluginException(No implementation found for method listen on channel lyokone/locationstream)

as referenced here: https://github.com/Lyokone/flutterlocation/issues/18

if I perform clean and rerun get packages, I get an actual crash:

Any updates regarding this?

GauravPatni on 12 Feb 2019

I am facing an issue too. I think it is due to the android support library and androidx transition.

Yutsa on 12 Feb 2019

The problem is caused by the changing to AndroidX and SDK 28. I have gone back to version 1.4.1 and that works fine. I don't need any of the 2.0 changes at this point.

jspinks on 12 Feb 2019

any solution yet?

ak2g on 17 Feb 2019

Hey ! I've found a partial solution, this seems to be a problem with gradlew:
Following this steps allowed me to pass the error:

Delete the flutter cache (<installation folder>/bin/cache);
Deletegradlew and gradlew.bat in android folder (and in some cases android/gradle/wrapper/gradle-wrapper.jar too);
Run flutter run again.

Hope it will help you, let me know !

EDIT:
Well with further investigation didn't seem to resolve the issue with AndroidX integration ... Still looking into it.

Lyokone on 18 Feb 2019

Okay finally found it, you have to make sure that your gradle.properties file contains this in order to have everything working with AndroidX:


android.enableJetifier=true
android.useAndroidX=true
org.gradle.jvmargs=-Xmx1536M

Please also make sure that you have those dependencies in your build.gradle:

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.2.0'
    }

I'll update the README this evening if I have some confirmations that it is working :)

Lyokone on 18 Feb 2019

Yes, it is working fine, in my case I have to update in app\build.gradle below the line.

compileSdkVersion 28

Hi Lyokone

Please update read.me. Below code is not working in updated version.

var currentLocation = {};

var location = new Location();

// Platform messages may fail, so we use a try/catch PlatformException.
try {
currentLocation = await location.getLocation;
} on PlatformException {
currentLocation = null;
}

Errors:-

await location.getLocation; is showing not future
await location.getLocation(); this function is returning LocationData not

When reverting back to 2.3.2, the problem goes away and the app does not crash on start.

Hey ! Thanks for bringing that, I'll check as soon as possible.

Lyokone on 1 Apr 2019

Hey, can you try to run flutter clean after updating to 2.3.3 ?
I've not modified anything that should cause a crash.

Lyokone on 1 Apr 2019

I have same issue here. I try to execute flutter clean but not solve the problem

ajzuse on 1 Apr 2019

Same here, no difference with flutter clean.

There must be something that changed that's causing the problem. If you want to post a link(s) to the changes you made, maybe we can take a look?

noordawod on 1 Apr 2019

Is not a solution, but if you downgrade to 2.3.2 it works correctly.

jfeliubadalo on 1 Apr 2019

Same issue here. Tried using version 2.3.2, did all the things prescribed in the README

@noordawod this is the link to the commit : https://github.com/Lyokone/flutterlocation/commit/b1b481ec1ad3c0227771cf05d115a3aa7f463ec4

If you find anything that could cause that ... I have multiple reports of people using 2.3.3 without any problem so I don't exactly know why It would not behave the same everywhere.

@Lyokone

According to (https://developer.android.com/reference/android/location/OnNmeaMessageListener), the android.location.OnNmeaMessageListener class is available from API 24. My app's lowest supported API level is 21.

Could you maybe add @TargetApi annotations where needed to limit the use of this class from API 24 upwards? You should probably add also runtime checks too.

@TargetApi(android.os.Build.VERSION_CODES.NOUGAT)
private void createLocationCallback() {
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.NOUGAT) {
    // ...
  }
}

Ohhh okay thanks a lot for catching that ! My bad there. I'll update this as soon as possible :/

Lyokone on 2 Apr 2019

Hey, the app shouldn't crash anymore on API level 21. I'll test the sample application on a simulator on API Level 21 to avoid those kind of errors in the coming release. Thanks to everyone involved in helping :)

Left you a comment on the commit. Unsure but I think you have a typo there.

noordawod on 8 Apr 2019

@Lyokone Was the issue is resolved in the latest release? Thanks alot for your work.

Same problem here. When having location: ^2.3.2 as a dependency, the app crashes when opening.

bpedazur on 12 Jun 2019

Hi. I'm facing another issue related to this. It happens only in Android and the location plugin version that I'm using is location: ^2.3.5, but I already tried to downgrade the version to see if it would solve it, but it didn't work.

Another bug that is occurring is that the permission is being asked multiple times, around 8. Again, this only happens when the Platform is Android.

Does anyone know what could be going on?

Here is how the error looks like:

Try adding

android.useAndroidX = true
android.enableJetifier = true

to your gradle.properties. For me this worked on 2.3.5

This did the trick for me too! Thanks!

This error is caused if _location.onLocationChanged().listen is called before _location.requestPermission() or _location.requestService()
