I am getting the mentioned error when I tried to build and run apk in android phone. I have deployed my back end server in nestjs and able to call an endpoint http://<server-ip>:3000/batch. I provided the same ip in environment in ionic angular app. When I tried to build, it build fine. I was also able to test the api end point in laptop's browser and all seemed fine. Now when, I exported the apk to android phone and opened the page, I get http failure response for 0 unknown error.
I have no clue as what is wrong and how to debug it.
Followed some threads at -
How to allow all Network connection types HTTP and HTTPS in Android (9) Pie?
I had a hope that it will probably work but it didn't.
I have cors enabled in my back end server -
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule, {
logger: ['error', 'warn', 'log', 'debug'],
});
app.enableCors();
await app.listen(3000);
}
bootstrap();
And following is the end point -
@Get()
@Header('Access-Control-Allow-Origin', '*')
@Header('Access-Control-Allow-Headers', 'Content-Type, Accept')
findAll(): Promise<Batch[]> {
this.logger.log(':: BatchController :: findAll()');
console.log(':: BatchController :: findAll()');
return this.batchService.findAll();
}
When I try to build apk using command ``, there are some errors that I see but it build apk successfully -

Explanation for issues of type "MissingDefaultResource":
If a resource is only defined in folders with qualifiers like -land or -en,
and there is no default declaration in the base folder (layout or values
etc), then the app will crash if that resource is accessed on a device
where the device is in a configuration missing the given qualifier.
As a special case, drawables do not have to be specified in the base
folder; if there is a match in a density folder (such as drawable-mdpi)
that image will be used and scaled. Note however that if you only specify
a drawable in a folder like drawable-en-hdpi, the app will crash in
non-English locales.
There may be scenarios where you have a resource, such as a -fr drawable,
which is only referenced from some other resource with the same qualifiers
(such as a -fr style), which itself has safe fallbacks. However, this still
makes it possible for somebody to accidentally reference the drawable and
crash, so it is safer to create a default dummy fallback in the base
folder. Alternatively, you can suppress the issue by adding
tools:ignore="MissingDefaultResource" on the element.
(This scenario frequently happens with string translations, where you might
delete code and the corresponding resources, but forget to delete a
translation. There is a dedicated issue id for that scenario, with the id
ExtraTranslation.)
