Answer 1

Please add the

android:exported="true"

to your Main Activity's activity tag in the AndroidManifest.xml file, like this:

1. Open Your Project's Android manifest, located at android/app/src/main/AndroidManifest.xml

2. Go to this line: android:name=".MainActivity"

3. Below this line, add android:exported="true"

The code should now look like this:

android:name=".MainActivity" // this must be the main activity
android:exported="true"
android:launchMode="singleTop" // this line can be something else, no worries

Explanation

What this does is that it tells Android to make this activity available to be accessed by another app, so that it can open your App. As the launcher (the app drawer/home screen) can be a normal app in android, the Main Activity must be exported to allow it to launch your app.

Answer 2

Go to android/app/src/main/AndroidManifest.xml and paste android:exported="true" after android:name=".MainActivity" like this:
