Android error Java compiler: uses or overrides a deprecated API

Question

I have an error in Android when compiling, it tells me for a particular activity the following error:

..ruta\NameActivity.java:
uses or overrides a deprecated API.
Recompile with -Xlint:deprecation for details.
Some input files use unchecked or unsafe operations.
Recompile with -Xlint:unchecked for details.

It lets me compile and execute the project but I would like to know what the error is because it does not mark any particular line for that error.

Imports:

import android.content.DialogInterface;
import android.content.Intent;
import android.graphics.Color;
import android.support.v7.app.AlertDialog;

app:

apply plugin: 'com.android.application'

        }
    }
    compileOptions {
        sourceCompatibility = 1.8
        targetCompatibility = 1.8
    }
}


dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:cardview-v7:28.0.0'

    implementation 'com.journeyapps:zxing-android-embedded:3.5.0'
}

I understand that it says: use or overrides a deprecated API. but I really don't know how to determine what this api is and I don't know how to gather more information about it
