Codelab walks you through tracking activity transition changes (start/stop run, walk, idle, drive, etc.).

codelab-activity_transitionapi's Issues

The Transition API is working fine on Galaxy S9 but got false positives on Pixel 5

I'm using the Transition API in a foreground service (by showing an ongoing notification) to constantly detect the user's physical activity transitions. It worked pretty well on Galaxy S9. However, when I tested the app on Pixel 5, I got multiple transitions from STILL to WALKING and WALKING to STILL even though the user was just picking up their phone and putting it back down. I was wondering if anyone encountered a similar issue. Thanks!

Application terminated or no activity reported on Android 13

I did no changes in the code, compiled, ran on Samsung with Android 13, application was terminated with following error, adding FLAG_IMMUTABLE to PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0) eliminates the exception, but no activity is reported

Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

Lab: Application Performance Management (APM) with Stackdriver

That lab does not seem to have its own repo. I'd be delighted if you could forward to the responsible party. Anyhow it fails. It seems that some images are missing. See screenshot.

Typo in Spet 4

Underneath the third code snippet, it says

Here we as if activity recognition is approved. If it is and activity recognition is already enabled, we disable it. Otherwise, we enable it.

Shouldn't it be?

Here we (check/verify) if activity recognition is approved. If it is and activity recognition is already enabled, we disable it. Otherwise, we enable it.

Broadcast receiver won't receive any activity transition

I tested this application, but it seems it doesn't work. (Cloned directly from this repo)

Inconsistent performance on Samsung S9 phone running Android 10

We compiled this example and it works well on a Google Pixel 2 running Android 11. We also integrated the activity transition API into our app and again, it works well on the Pixel 2. Then we started testing on a Samsung S9 and we are getting mixed results. As mentioned, we integrated the Activity Transition API into our app as well, and had both installed on the same phone for comparison. We also downloaded and installed other apps that utilize the Activity Transition API. We wanted to rule out any bugs in our code or possibly the demo code.

It was working fine for a while, then the API just suddenly stopped reporting activity transitions to all the apps. Our app creates a log for debugging and we can see our app suddenly just stops receiving activity transition updates. At the same time we checked the other apps and found the same result - all of them stopped receiving transition updates at the same time. Even after a full hard reboot of the Samsung phone, none of the apps were receiving transition updates anymore. Even tried uninstalling / reinstalling apps - no difference. All activity transitions stopped.

Then suddenly, they will start coming again. We do nothing different. All the apps registered for activity transitions suddenly started receiving them again. Then they will stop again as suddenly as they start.

We have tested with a few other phones and so far the Samsung S9+ is the only one doing this. There doesn't seem to be a pattern either. We can leave the phone sitting for hours, pick it up, and it works. We can do many transitions sequentially and it works. Then when it decides to stop working, we cannot get it working again even with a reboot. We just have to wait until it decides to work again.

Perhaps the codelab should link to where the repository is, instead of directly to the zip file:

https://github.com/googlecodelabs/activity_transitionapi-codelab

android 12 specifying mutability flag

in https://developer.android.com/codelabs/activity-recognition-transition#5
you should not pass 0 for the flags rather the pending intent needs tp specify the mutability flag.
mActivityTransitionsPendingIntent =
PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0);

ACTIVITY_RECOGNITION IS NOT TAKING

Typo in step 5

In the Register a BroadcastReceiver for the transition section the

search for TODO: Register a BroadcastReceiver to listen for activity transitions

sentence should be replaced by

search for TODO: Register the BroadcastReceiver to listen for activity transitions

onreceive never called

no changes, only updated pending intent flags and build , its never called onreceive in API 33.

The process to Remove updates when app is closing is duplicated in this Codelabs tutorial.

The process to remove updates when the app is closing is repeated along with the code to follow in step 6 (Setup activity transitions and request updates).
I have added the link for reference here.https://codelabs.developers.google.com/codelabs/activity-recognition-transition/index.html?index=..%2F..index#5

Is there a bug in samsung phone?

I am using s22, android 12.
When receive an intent ,there is extra :"com.google.android.location.internal.EXTRA_ACTIVITY_RESULT", however from the source code:
return !hasResult(var0) ? null : (ActivityTransitionResult)SafeParcelableSerializer.deserializeFromIntentExtra(var0, "com.google.android.location.internal.EXTRA_ACTIVITY_TRANSITION_RESULT", CREATOR);

It should be com.google.android.location.internal.EXTRA_ACTIVITY_TRANSITION_RESULT, so Is there a bug in samsung phone?

TransitionReceiver

TransitionReceiver is not a class that I can access when I make this variable in my own empty project (not using the codelab file). It shows highlighted read when I try to make this a variable - see pictures attached.

I am using Android Studio version 4.0.1.

Any ideas what class I can use to replace this?

Wrong link to github repository

The link to repository download is not working, as it is
https://github.com/googlecodelabs/activity_transitionapi-codelab/BasicActivityTransitionsCodelab.zip

and it should be:

this codelab does not work

`requestActivityTransitionUpdates` throws `SecurityException` after some time and stops getting activities

Hi.
This happens after 2~3 days of using my app to track walking and running. Here is the code which is called every hour in the onStartJob of a JobService.

val request = ActivityTransitionWalkRequest.build()
val client = ActivityRecognition.getClient(appContext)
client
                .requestActivityTransitionUpdates(request, getPendingIntent(context))
                .apply {
                    addOnSuccessListener { onDone.invoke(true) }
                    addOnFailureListener { onDone.invoke(false) }
                }

I see from my logs that addOnSuccessListener is called, but also that the a SecurityException is thrown, and my BroadcastReceiver doesn't receive any transition events anymore. Here is some stacktrace:

What can be the cause of this?
Thanks for any help. I can provide more source if needed.

Extra Note
in the addOnSuccessListener callback, I register a broadcast receiver like this:

unregisterReceiver(transitionsReceiver)

if (transitionsReceiver == null) {
    transitionsReceiver = ActivityTransitionReceiver()
}
registerReceiver(transitionsReceiver, IntentFilter(RECEIVER_ACTION))

Another observation: after restarting the phone, the security exception is no longer thrown and I receive transition updates.

Device / OS
Pixel 6 / Android 13

Not Working

I am using Android 9 Xiaomi but it is not working.

TransitionsReceiver Intent extras is always null

I ran the complete debug variant of the app on Galaxy Z Flip 3 5G (Android 12) and Xiaomi Redmi K40 (Android 12). After walking for a 10 metres or so, TransitionsReceiver.onReceive was called. I assume it was walking activity detected. But intent.getExtras() was null. Hence, ActivityTransitionResult.hasResult(intent) returned false, and no information was printed.

I tried 31 and 32 for targetSdkVersion and compileSdkVersion

What is the issue?

It does not work

No activity is detected.

Example code not running on device

The sample app is not running on any of the Android 10 devices we tested on despite following the tutorial fully. Perhaps some permissions have changed?

ActivityTransitionAPI Pending Intent not working in background

I am trying the Activity transition API to detect the user activity, it is working fine when app is in foreground, but as soon the get closed from recent app list, the detection of Activity is stopped. The broadcast receiver is not receiving any change in activity after app close.

typo

There's the sentence "Here we as if activity recognition is approved. If it is and activity recognition is already enabled, we disable it. Otherwise, we enable it."

The word 'as' should be 'ask'.

No activity changes detected

Hi!

I have donwloaded and executed the code you provide but no activity is being detected. Is ther a problem in the code du to recent Android updates? What can be done to have the app work as expected?

Thanks in advance for your answer.
