Tesseract branch: App crashes on using RNTextDetector.detect #23

I'm trying the tesseract branch on android using the example given in the Readme but the app crashes as soon as the detect method is called. The app crashes without giving any error message and running 'react-native log-android' shows nothing either.

I'm having the same issue; seems to have something to do with accessing the tessdata files. You can see the native crash messages by running in Android Studio.

E/RNTextDetector: ERROR: Creation of directory /storage/emulated/0/com.myapp/tessdata failed, check permission to write to external storage.
E/RNTextDetector: Unable to copy files to tessdata java.io.FileNotFoundException: /storage/emulated/0/com.myapp/tessdata/eng.traineddata: open failed: ENOENT (No such file or directory)

I do have the file at android/app/src/main/assets/tessdata/eng.traineddata as per the README, hm...

In Android Folder, open AndroidManifest file and add android:requestLegacyExternalStorage

<manifest ... > <application android:requestLegacyExternalStorage="true" ... >
