Trying to compile an extension

[Patryk_F]

You need to show your code from line 12 and the part of the code where this constant is used. You are probably using functions not available in java8.

[HarshVardhanSolanki]

I make property of that and it got solved,

But the error is coming for this code now.

Error:

I think this is the last error.

[Patryk_F]

Instead of pasting images, paste copied text.

private static final int RTC_WAKEUP = 0;
@SimpleProperty
public int RtcWakeup() {
return RTC_WAKEUP;
}

[HarshVardhanSolanki]

@Patryk_F

private static final int RTC_WAKEUP = 0;
@SimpleProperty
public int RtcWakeup() {
return RTC_WAKEUP;
}

Should i need to change it

[Patryk_F]

Yes, Yes because this:

@SimpleProperty
public static final int RTC_WAKEUP = 0;

won't work.

[HarshVardhanSolanki]

Also I mentioned the error above, I think this is the last error.

[Patryk_F]

What is the IAlarmManager class? I don't know such a class, what package does it come from? Did AI generate your code?

[Patryk_F]

Please show more code, as you're probably not using annotations correctly.

[Kumaraswamy]

You should stop randomly pasting the codes from somewhere and expect them to work after adding annotations.

I would suggest you learn extreme basics of Java, it really helps a lot. Otherwise it would require countless discussion to correct your code. Which is beyond the scope of this topic related to Rush.

[HarshVardhanSolanki]

I am taking help with Jewel and he is giving good help,

He fixes my some of my code
but the fixed code is giving error.

The code he suggested.

public boolean isTimeZoneSet = false;
    public static final long INTERVAL_FIFTEEN_MINUTES = 15 * 60 * 1000;
    public static final long INTERVAL_HALF_HOUR = 2 * INTERVAL_FIFTEEN_MINUTES;
    public static final long INTERVAL_HOUR = 2 * INTERVAL_HALF_HOUR;
    public static final long INTERVAL_HALF_DAY = 12 * INTERVAL_HOUR;
    public static final long INTERVAL_DAY = 2 * INTERVAL_HALF_DAY;

    public AlarmManager(ComponentContainer container) {
        super(container.$form());
        this.container = container;
    }

       public static class IAlarmManager {
        public static final int RTC_WAKEUP = 0;
        public static final int RTC = 1;
        public static final int ELAPSED_REALTIME_WAKEUP = 2;

Why recreate something that has already been created? The source code is even provided. Start learning how to write extensions with something simple.

[FREE] Alarm Extension

After having published a first extension and after what was commented by the leading users, about what had to change in the extension, I published it again with the recommended changes. The extension now complies with the nomeclature instructions indicated in I also try to adapt it to what is indicated in Is it novel? Has your type of extension been done before by other extension developers. Do we really need it again? What is different/unique about it, when compared with the other simil…

[HarshVardhanSolanki]

This one is different

[Taifun]

Please also follow the naming conventions

Naming Conventions for Extension Developers

If you are developing an extension, then please follow the naming conventions, which is UpperCamelCase for the package name as well as for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names, no underscores . Example [naming] What does UpperCamelCase mean? UpperCamelCase (part of CamelCase ) is a naming convention in which a name is formed of multiple words that are joined together as a single word with the first l…

And in case you need inspiration of some features to add, let me suggest to take a look at App Inventor Extensions: Alarm Manager | Pura Vida Apps

Your full code is repeated, it is duplicated.

[HarshVardhanSolanki]

How can install andriod lib in VS Code? already searched alot.

[AyProductions]

@HarshVardhanSolanki

How can install andriod lib in VS Code?

why do you want to install android lib in VS Code?

[HarshVardhanSolanki]

To code by import android.*;

[Patryk_F]

What class do you need exactly?

[Horizon]

I don't feel it's possible because dev-deps don't contain android classes(what exactly I can remember from my past experience, as I have left extension development for sometime).

[HarshVardhanSolanki]

Any of the android to explore and code.

Is there any way.
