'NullPointerException:tempt to invoke virtual method 'android.graphics.drawable.Drawable android.graphics.drawable.Drawable$ConstantState.newDrawable

Can I know the what is this error and a solution for this? This error occurred at react native apps randomly, in both debug mode and APKs. reproducing this error is difficult.

I saw this issue in github github-https://github.com/facebook/react-native/issues/17530.

but the solution is not a proper one. Is there a proper solution for this error.

react-native

Solution 1:^[1]

It occurs randomly. Just uninstall the app from mobile and restart the server by resetting the cache.

Solution 2:^[2]

Just close the app and open it again the problem will be solved. But if anyone knows a better way please let me know.

Solution 3:^[3]

Try to run below command. This worked for me.

npm start --reset-cache

Solution 4:^[4]

You can try both and either of the points, whichever works for your app:

Delete the cache data of your app and let it reload
Restart the server using npm start --reset-cache

Solution 5:^[5]

For me this error was resolved so I closed npm and then executed the:

`react-native run-android.`

Solution 6:^[6]

https://github.com/facebook/react-native/pull/29452/files Hope this works. This error arrives due to multiple rerendering of textInput(s).

Solution 7:^[7]

close the app
restart the server using npm start --reset-cache
npm run android

(didn't need to uninstall the app)

Solution 8:^[8]

Add the flowing line of code into /android/app/src/main/res/values/styles.xml.

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
       <item name="android:editTextBackground">@android:color/transparent</item>
       ...
</style>

Hope this will work. Happy coding.....
