I am new to Ionic/Angular and I was hoping for some help.
I want to output the device battery level on the screen using the Capacitor Device plugin but I can't work out how. I have managed to log it in the console correctly but don't know what I need to do display it on the front end.

You're not a million miles off. You need to declare a variable and then call that variable in the HTML file. So in your case:

I have tried this and it should work
Once you have your
doc loaded, we can use the
get_element_by_id() function to get the element that we need, which has an id = 'batterylevel'. This will give you the whole element.
I kept getting the error

in my debugger output so I decided to try running the example code provided by Apple here and got the same error. I've tried multiple computers and Xcode versions, multiple example projects from different sources and nothing has worked.

A couple of potential issues:
This happens when testing on the simulator. Use a physical device.
Make sure your
Info.plisthas a “Permitted background task scheduler identifiers” (i.e.
BGTaskSchedulerPermittedIdentifiers) entry with the identifier for your background task.
Make sure you set your breakpoint immediately after the
BGTaskScheduler.shared.submit(...)line and that you perform the
submitwas called. I.e., make sure you are even getting to the
submitcall. (See next point.)
Notably, the Apple example (and your example) are scheduling it in
applicationDidEnterBackground(_:). But if you are using a
UIWindowSceneDelegate(i.e. in your
SceneDelegate), then the app delegate’s
applicationDidEnterBackground(_:)is not called, but rather the scene delegate’s
sceneDidEnterBackground(_:)is. I put the scheduling of the
BGAppRefreshTaskRequestin the scene delegate’s

Some of my users have head unit devices on Android (in their cars) and of course such device doesn't have battery and the next code returns
val batteryLevel = batteryManager.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY)
and the next method will return

You can use
BatteryManager.EXTRA_PRESENT which according to the documentation, exposes a:
boolean indicating whether a battery is present.
got here Android 10 (also Android 8). Battery Optimization is off . The problem only happens if my Device is on the charger. After approximately 48hrs it dies .
I tried to solve this by waking the device up periodically (after 8hrs) . Today it last sent data to the server at 3:00 , so I thought it is dead. But to my big surprise , it still woke up at 08:00 . Unfortunately after touching the screen , to try to open something . Android forced me to close the app.
Here is the part of the code :
(excuse me for the length, it looks to be long , but is is the bare minimum , I thought I'd include every procedure and function I use in order to perhaps help someone smarter then me see if I am leaking memory or doing something horrible, note : this very same code is NOT crashing or hanging after weeks if Device is not on the charger)...

IIRC on mobile devices there is no guarantee that the Android/iOS system will let an application live forever. It is very possible that your app is killed by the OS sending a
SIG_ABRT after a while, to release resources.
Another possibility is that there is an OOM after too many threads. The log error indicates that there is a problem creating a thread.
Perhaps each DB connection uses a thread, which is not released, so after a while, it crashes. Please remove the DB connection and try again. It may help isolate the root cause of your problem. Also try to log the memory consumption, to see if there is no leak for this long-standing app.
Anyway, I would rather use REST service over HTTPS+JSON for app communication, instead of the bloated DataSnap RAD client.
I have just Copied the code from flutter.dev and modified it and getting following error
E/flutter ( 2639): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method myNativeFunction on channel My Channel) * I want to print a message from Native java code to Flutter UI *...

MainActivity, method channel name should match the method channel name defined in dart.
I have a simple Android app. I imported a new flutter module. When I pass to the Flutter page, I can not implement native code anymore. I got an error
No implementation method found for method getBatteryLevel. How can I fix this?
Note: If I run the flutter module itself, I can get the result of native code.
The triggered method in main.dart:...

Please specify the method channel in your dart code as exact as the CHANNEL string in your native code. For this scenario, you will have to write the below code in your flutter side code
I have an app that is using BLE connectivity with my device. Everything works from connecting to the device, discovering the services, writing the characteristic and descriptor. But for some reason, onCharacteristicChanged is not triggering. The goal is to retrieve the data from the characteristic that is in the characteristic. I have tried using a different characteristic from the same service and this works as in retrieving the data. Not sure why this specific characteristic is not working when others are.
Here is my code: //Descriptor public final static UUID UUID_CLIENT_CHARACTERISTIC_CONFIG = UUID.fromString(GattAttributes.CLIENT_CHARACTERISTIC_CONFIG);...
ANSWERAnswered 2020-Dec-14 at 17:08
Found the solution. The third-party forgot to mention that I had to set the right value to enable the characteristic. I tried that and it worked! Finally, got data values.
I have been working on a react native application where I have to fetch the geolocation at an interval of 10secs and update it to a server. I was able to do the same when the emulator was active/ in the foreground.
However, when the app is minimized, it doesn't work. I tried using expo task manager but the function doesn't seem to run when backgrounded.
What is the error here? I have attached my code and output.

To anyone who is looking at this later, please make sure that you test your app on a physical device. Emulator doesn't really support the task manager and background fetch properly!

You can use BatteryLevel like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the BatteryLevel component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
