I am not able to make PDF in ANDROID API LEVEL 29. It is working fine in API LEVEL 28. So I downgraded RN version from 0.63.2 from 0.62.2 and Gradle 3.5.3 to 3.5.2 according to this issue https://github.com/christopherdro/react-native-html-to-pdf/issues/189

also followed https://github.com/christopherdro/react-native-html-to-pdf/issues/149 this too. It says Permission error so inside componentDidMount() I have added following line

PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE)

But still no luck. I am getting following error.

Solution

I found solution from this link

If you find out that your app is not able to make any file or folder you should add

android:requestLegacyExternalStorage="true" in your `<application>` in `AndroidManifest.xml`

for more details Official Link and Other StackOverflow Question Answsers

Remember: I am using React Native and only in Android API 29 and above I stuck in this issue.
