This is an extension of a question I asked before.
I'm using the recent version of MLKit Object Detection (which doesn't require firebase). I'm using a custom model, and CameraX, to detect objects and label them/get info.
Right now, with the code I have, it can detect that objects are present in the area, but:
No labels or bounding boxes are showing up;
It is not detecting more than one object at a time;
Once it detects an object, the app won't "change" (i.e when I move the phone, to try to detect another object, nothing in the display changes.
Here is my code:

So I figured it out. When adding a TensorFlow model to help with the object detection, apparently it has to contain metadata (so that that way, when you want to call "getLabels()" and its appropriate methods, it will actually return a label. Otherwise it will return nothing and cause errors apparently.
This is the one I used that worked: mobilenet_v1_0.50_192_quantized_1_metadata_1.tflite
To answer your #3 question:
Once it detects an object, the app won't "change" (i.e when I move the phone, to try to detect another object, nothing in the display changes.
I'm guessing this is caused by the fact that your imageProxy().close needs to be a part of an OnCompletedListener else it will cause various threading issues and possibly be leading to the blocking of any additional images from being processed that you mention.
i.e.:
Change this:
objectDetector
.process(image)
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
//Toast.makeText(getApplicationContext(), "Fail. Sad!", Toast.LENGTH_SHORT).show();
//textView.setText("Fail. Sad!");
imageProxy.close();
}
})
.addOnSuccessListener(new OnSuccessListener<List<DetectedObject>>() {
#Override
public void onSuccess(List<DetectedObject> results) {
for (DetectedObject detectedObject : results) {
Rect box = detectedObject.getBoundingBox();
for (DetectedObject.Label label : detectedObject.getLabels()) {
String text = label.getText();
int index = label.getIndex();
float confidence = label.getConfidence();
textView.setText(text);
}}
mediaImage.close();
imageProxy.close();
}
});
to this:
objectDetector
.process(image)
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
//Toast.makeText(getApplicationContext(), "Fail. Sad!", Toast.LENGTH_SHORT).show();
//textView.setText("Fail. Sad!");
imageProxy.close();
}
})
.addOnSuccessListener(new OnSuccessListener<List<DetectedObject>>() {
#Override
public void onSuccess(List<DetectedObject> results) {
for (DetectedObject detectedObject : results) {
Rect box = detectedObject.getBoundingBox();
for (DetectedObject.Label label : detectedObject.getLabels()) {
String text = label.getText();
int index = label.getIndex();
float confidence = label.getConfidence();
textView.setText(text);
}}
}
}).addOnCompleteListener(new OnCompleteListener<List<Barcode>>() {
#Override
public void onComplete(#NonNull Task<List<Barcode>> task) {
imageProxy.close();
}
});
Note I did not check the accuracy of your curly brace locations/levels, so ensure you have those correct as well.
I had similar issues, among others all related to this missing OnCompleteListener. See the original reasoning I found here and how this applies more specifically to the Task object created by your objectDetector.process(image), or in my case Task<List<Barcode>> result = scanner.process(image) here for details.

So I have an application which has to monitor and range after beacons and than calculates the position of the user. After calculating this , the value is passed to the Wayfindigoverlayactivity.class where the value should be putt on the map with the blue dot.
I don know how to assign the value to the blue dot but before that my application is working on an endless loop and is opening the activity on ranging about 100x .

The second class is not fully posted , only where I make changes.
The intent in the second class is in the OnCreate part
The location is calculated in the logcat , the only problem is that the application is working in a loop
Please help me , I am stuck. Thanks
I guess, you only need to open RangingActivity from onCreate() of WayFindingOverlayActivity if center is null. This means, we need to open RangingActivity to get the value for center. Doing null check for the center will also ensure that the application doesn't go in loop and proceed when we have the value for center. The code in the onCreate() of WayFindingOverlayActivity may look like this :
// edited here
Bundle extras = getIntent().getExtras();
if(extras == null){
Intent myIntent = new Intent(this, RangingActivity.class);
this.startActivity(myIntent);
} else{
LatLng center = extras.getParcelable("b");
Log.d("Location!!", center);
// call showLocationCircle() to show the blue dot
showLocationCircle(center, yourAccuracyRadius);
}
I'm developing an app which can share local music on your phone to other devices. To connect several devices I am using Googles Nearby API. After starting to advertise and to discover on two devices, the onEndpointFound calls a found device on both devices. To accept this connection the app should show up an AlertDialog. This happens in the onConnectionInitiated method. But for some reason the app won't get to the part where the AlertDialog is built.
Does anybody know how to fix this?

Given the additional detail in the comments, this appears to be a Bluetooth Classic issue. I looked in our records, and we have both reported devices so we'll try to reproduce on our end.
Some steps you can do:
1) Try rebooting the devices and see if the issue is reproducible.
2) Collect logs (adb logcat) or a bugreport (adb bugreport) from both devices and attach them to this post or email them to me directly at {my username}#google.com. These contain sensitive data, so only send it if you have test accounts on both devices. If you have a personal account, then filter the logs first (adb logcat NearbyConnections:* NearbyMediums:* *:S)
Disclaimer: I work on Nearby Connections
I and my team mates are using MI band 3 to record data from Google Fit API. We are using a third party app - 'Notify and Fitness for MI Band' to sync the data. We are unable to get the Instantaneous Heart Rate.
We are using DataType.TYPE_HEART_RATE_BPM, DataType.AGGREGATE_HEART_RATE_SUMMARY to get the average highest and lowest heart readings but the Instaneous readings are not showning

Expected solution : to display the instaneous data
Fitness.getRecordingClient(this, GoogleSignIn.getLastSignedInAccount(this))
.subscribe(DataType.AGGREGATE_HEART_RATE_SUMMARY)
This won't work; you need to subscribe to DataType.TYPE_HEART_RATE_BPM.
Could you point me to where you're trying to read instantaneous heart rate? I couldn't see it in the code.

I expect the function useroffroute overridden by me gets triggered.But no trigger happens as in am not able to see the toast message and file creation when the user goes offroute.
So the first thing to address here is that this will definitely not work with NavigationLauncher. That object is really meant to be a full-featured solution to get nav up and running quickly with minimal customization. So it is not quite as flexible and doesn't allow you to modify your offRoute listeners. This is only possible with NavigationView.
It's easy to miss, but the documentation for how to override the default reroute behavior is actually outlined in the Map Matching docs: https://docs.mapbox.com/android/navigation/overview/map-matching/#map-matching-with-mapboxnavigation
With that in mind, it looks like you're missing one crucial step in your code. When you add an offRouteListener to you navigation object, you need to carry through and override the userOffRoute function. Which would end up looking like this:
navigation.addOffRouteListener(new OffRouteListener() {
#Override
public void userOffRoute(Location location) {
Toast.makeText(getApplicationContext(), "Off route detected.........", Toast.LENGTH_SHORT).show();
// Make sure you call for a new DirectionsRoute object
// and end by calling MapboxNavigation#startNavigation on a successful
}
});
My app is supposed to display a Google Map with a heatmap, but I can't even get the map to display. It's only showing the logo in the bottom left corner. There seems to be no errors. I also checked the gradle and all the necessary dependencies are there. I can't tell if this is due to an actual error or lack of memory/slow processing.
