React Native app starts to a white screen

Question

I'm using React Native to develop an Android app. Sometimes, after I run react-native run-android and my app starts, it hangs on a white screen. Shaking my phone doesn't do anything, and when I click 'pause' in the VSCode debugger it has no effect. If I press the Home button to background the app, then click on the app again, it launches normally and debugging works as expected. Is this a known issue? What can I do to fix it?

For a really good fix to this problem going forward see my solution here: https://stackoverflow.com/a/65958958/5354268 — Shane Sepac, Jan 29 '21 at 17:27

Open your android folder in Android studio
Press the green Play button
Open the logcat window from the bottom bar
Make sure the Device and Process are point to the right value, then inspect any error there

I don't have this problem, you need to inspect what happened at run-time to see how to fix this.

I had the same issue, checked the logcat and found I had some errors to deal with. – Punter Bad Nov 11 '20 at 09:53
Useful tip... I had [this](https://stackoverflow.com/questions/43368926/android-reactnative-java-lang-unsatisfiedlinkerrorcould-find-dso-to-load-libre/45628767) error, and the solution `./gradlew clean` in android folder fixed the blank white screen – Dror Bar Jan 19 '22 at 13:43

have you resolve this issue? if you use react-native-vector-icons, make sure you update those fonts(Octicons.ttf and etc) in assets/fonts. it works fine on iOS but on android, whenever the app is installed then sometimes it gets blank white screen after splash, but it works fine sometimes as well. it is just randomly happened once i updated them, it works fine

Posting answer for people hitting this question possibly facing the same issue as me - blank white screen on android, ios working fine:

Make sure in your MainActivity.java you have getMainComponentName() function:

public class MainActivity extends ReactActivity {

    @Override
    protected String getMainComponentName() {
        return "devApp3";
    }
}
