nice update!

StarredStare · December 31, 2021, 12:02pm

I tested your extension and it's working

gordonlu310 · December 31, 2021, 12:03pm

Thanks. I received your message already.

If you don't know, @StarredStare is my classmate.

gordonlu310 · January 1, 2022, 4:44am

This extension is now added to my website.

gordonlu310 · January 1, 2022, 5:49am

I realized that this extension does not work on the App Inventor emulator.

When I added this component to the project, it gave me a huge, unreasonable runtime error, so don't test it with the eumlator.

Nice extension @gordonlu310

nishyanthkumar · January 3, 2022, 9:38am

Maybe the emulator doesn't support this feature...?

AyProductions · January 4, 2022, 12:46pm

It's because the emulator is very old I guess. It is just like it was last updated 9-10 years ago... Android is too old on it. Android has very updated now so it supports on the latest new android os!

Know_About_IT · January 4, 2022, 1:33pm

Nice extension

An Alternative

[Beta] DevyInfo : Get info your device - Extensions - Kodular Community

gordonlu310 · January 5, 2022, 9:27am

That extension is so crazy - probably the extension developer put a lot of effort in it.

gordonlu310 · January 5, 2022, 10:20am

Version 6 Added!

I would like to thank @Taifun a lot for this update, they let me learn a lot from their extension!

Implemented from Battery Utilities from Kodular.

New blocks:

Method blocks

BatteryHealth

Returns the health value of the phone's battery. Can be: UNKNOWN, GOOD, OVERHEAT, DEAD, OVER_VOLTAGE, UNSPECIFIED_FAILURE, COLD.

Returns: text

BatteryPercentage

Returns the battery level in percentage.

Returns: int

BatteryTechnology

Returns the battery technology.

Returns: int

BatteryVoltage

Returns the current battery voltage.

Returns: int

IsBatteryPresent

Indicating whether a battery is present.

Returns: boolean

Property Blocks

BatteryCharging

Returns true if the device is charging, else false.

Returns: boolean

BatteryPlugged

Returns the device the phone is plugged to. Can be 'USB', 'AC', 'WIRELESS' or 'UNKNOWN'.

Returns: text

NOTE: Remember to distinguish the above blocks. They are 100% different.

AyProductions · January 5, 2022, 12:38pm

@gordonlu310. THIS IS THE BEST UPDATE YET!

gordonlu310 · January 6, 2022, 10:18am

Launching next version tomorrow or later, probably after my math test.

This is what it is going to be:

BTW: Have you voted yet for OS? Today is the last day!

https://community.appinventor.mit.edu/t/free-get-device-info/48411/18?u=gordon_lu

gordonlu310 · January 6, 2022, 1:21pm

Voting poll closed. If you want to know some part of the code, PM me.

gordonlu310 · January 7, 2022, 7:25am

Hi everyone,

I finally have some time after my test, so I'm introducing version 7. I implemented some more blocks from the Kodular components of Device Utilities, Battery Utilities and Color Utilities, and even some of my own.

Methods

BatteryPluggedSource

Returns the device the phone is plugged to. Can be 'USB', 'AC', 'WIRELESS' or 'UNKNOWN'.

Returns: text

Removed the old property block of BatteryPlugged.

BatteryStatus

Returns the current status of the phone's battery. Can be: UNKNOWN, CHARGING, DISCHARGING, NOT_CHARGING or FULL.

Returns: text

ColorConvertHexToInt

Convert a hex color to a integer color. The result is returned as integer. This function does not support shorthand hex values like #000. The expected parameter for hexColor is something like #FFFFFF.

Returns: int

Parameters: hexColor = text

Note: When I say a hex color, I do not include hexadecimal values. Thank you very much.

ColorConvertIntToHex

Convert a integer color to a hex color. The result is returned as string.

Returns: int

Parameters: intColor = number (int)

DisplayCountry

Returns a name for the locale's country that is appropriate for display to the user.

Returns: string

DisplayLanguage

Returns a name for the locale's language that is appropriate for display to the user.

Returns: text

DisplayScript

Returns a name for the the locale's script that is appropriate for display to the user.

Returns: text

GetLuminanceOfColor

Returns the relative luminance of a color. This block only supports devices above or Android 8.0.

Returns: number (float)

Parameters: color = number (long)

NumberToString

Converts a number to a string.

Returns: text

Parameters: number = number (int)

StringToNumber

Converts a string to a number.

Returns: number (int)

Parameters: string = text

Property

CpuTemperature

Returns the CPU temperature of the device.

*Returns: number (float)

This is an Open Source property.

How do you calculate the CPU temperature?

Import these:

import java.io.BufferedReader;
import java.io.InputStreamReader;

Then use this:

    @SimpleProperty(description = "Returns the CPU temperature of the device.")
    public static float CpuTemperature () {
    Process process;
    try {
        process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone0/temp");
        process.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = reader.readLine();
        if(line!=null) {
            float temp = Float.parseFloat(line);
            return temp / 1000.0f;
        } else {
            return 51.0f;
        }
    } catch (Exception e) {
        e.printStackTrace();
        return 0.0f;
    }
}

Feel free to copy the code and add it to your extension!

AyProductions · January 7, 2022, 9:35am

good/great update @gordonlu310!

qwe_rfv · January 7, 2022, 9:40am

What do these have to do with device information?
NumberToString and StringToNumber can be easily done with app inventor blocks:

gordonlu310 · January 7, 2022, 9:43am

off-topic

The ColorConvertHexToInt and ColorConvertIntToHex are in the Kodular documentation, so I was planning to implement them in my extension. They have something to do with that - they are utility blocks, else Kodular won't add them.

There is a way to convert numbers or strings, though.

oseamiya · January 7, 2022, 11:47am

I have made a library for getting device informations some months ago for my android studio application and is open-source here. You can look over to these codes and add some more too :))

Congratulations for the extension

gordonlu310 · January 8, 2022, 12:08pm

Version 8!

Big thanks to @oseamiya for this version, I can't create this update without your code.

Methods

CurrentLatitude

Returns the user's current latitude.

Returns: number (double)

Note: I tested this block with the LocationSensor, and found that this block is a bit faster than that. You can use both of them in the app, but I would not suggest you because this is available with built-in blocks.

CurrentLongitude

Returns the user's current longitude.

Returns: number (double)

Note: I tested this block with the LocationSensor, and found that this block is a bit faster than that. You can use both of them in the app, but I would not suggest you because this is available with built-in blocks.

DisplayFontScale

Returns the font scale of the display.

Returns: number (float)

DisplayHeight

Returns the display height of the device.

Returns: number (int)
