How to change React Native Android's default text color to black?

Question

Currently it's light grey, but I'd like to change it to black, I've tried multiple attempts as found online but it still doesn't work. Please help if you can, thanks!

Version: 0.43.1 (Cannot change for now due to commercial reason)

I've tried several syntax combinations, deleting the build folder and running react-native run-android and nothing is changing.

I would not prefer using any global styling library, because I'd like to minimize overheads to an already bulk codebase.

Here's my AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
	package="com.xxxxxxx"
	android:versionCode="1"
	android:versionName="1.0"
	android:installLocation="internalOnly">

	<application android:icon="@mipmap/app_icon"
	    android:label="@string/app_name"
		android:name=".MainApplication"
		android:manageSpaceActivity="com.salesforce.androidsdk.ui.ManageSpaceActivity"
        android:theme="@style/AppTheme"
	>

		<!-- Launcher screen -->
		<activity android:name=".MainActivity"
				  android:label="@string/app_name"
				  android:screenOrientation="landscape"
				  android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
			<intent-filter>
				<action android:name="android.intent.action.MAIN" />
				<category android:name="android.intent.category.LAUNCHER" />
			</intent-filter>
		</activity>

        <activity android:name="com.facebook.react.devsupport.DevSettingsActivity"
				  android:screenOrientation="landscape" />

	</application>

    <uses-sdk android:minSdkVersion="19"
        android:targetSdkVersion="25" />

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

	<uses-permission android:name="android.permission.RECORD_AUDIO"/>
	<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

	<uses-permission android:name="android.permission.BLUETOOTH"/>         <!-- for Device Name -->
	<uses-permission android:name="android.permission.READ_PHONE_STATE"/>  <!-- for Phone Number -->

</manifest>

Here's my folder structure:

And here's my styles.xml:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:textColor">#000</item>
    </style>

</resources>

Answer 1

Create the theme in styles.xml, and apply it in the manifest. Here's what ours looks like:

android/app/src/main/res/values/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
  <item name="android:textColor">#000000</item>
</style>

AndroidManifest.xml:

<application
  ...
  android:theme="@style/AppTheme">
