🐛 App crashes on launch after obfuscated by Dexguard in Android
What's happening?
We're using vision-camera for scanning the barcode. We had no error while running on debug and release mode and the application worked as expected when the obfuscation was disabled. However, after obfuscating the application by using dexguard(enterprise proguard) , the application started to crash on splash screen. I couldn't find any keep rule in the documentation.
Before installing the library, there was no crash in the application.
Reproduceable Code
const device = useCameraDevice('back');
device && (
<View style={{ flex: 1 }}>
<Camera
testID="rncamera-view"
fps={30}
codeScanner={codeScanner}
device={device}
style={StyleSheet.absoluteFill}
isActive={true}
/>
<BarcodeMask
outerMaskOpacity={0.5}
lineAnimationDuration={1200}
width={Dimensions.get('screen').width * 0.7}
height={Dimensions.get('screen').height * 0.25}
/>
{overlay && barCode === '' && (
<CameraOverlay>
<Image
source={warningImage}
style={{ width: 40, height: 40, flexDirection: 'column', marginRight: 20 }}
/>
<CameraOverlayText>{t('overlay')}</CameraOverlayText>
</CameraOverlay>
)}
</View>

Hey - sorry I don't really think this is related to VisionCamera.
Maybe try removing this line: https://github.com/mrousavy/react-native-vision-camera/blob/7905f2c057869698a4f5afa3182bec4cd2a5fe58/package/android/build.gradle#L145
Hi @mrousavy I'm sorry for not getting back to you sooner.
We removed the line you mentioned, but it didn't work. I'll get back to you tomorrow with the details.
Thank you.
Hi @mrousavy
I removed the line you mentioned. However, I got a different crash from the application.
couldn't find DSO to load: libjscexecutor.so

libjscexecutor.so is also different .so file that is placed in the gradle file of the library. Should I remove it ?
- first install this in your device npm install @react-native-camera/core @react-native-camera/barcode 2)make sure you have linked the packages correctly. If you are using React Native 0.60 or above, auto-linking should work. 3)try this code according to your preferences;
import React, { useEffect, useState } from 'react'; import { StyleSheet, View, Dimensions, Image } from 'react-native'; import Camera from '@react-native-camera/core'; import BarcodeMask from '@react-native-camera/barcode-mask'; import { useCameraDevice } from '@react-native-camera/core';
const CameraScreen = () => { const device = useCameraDevice('back'); const [barCode, setBarCode] = useState('');
const handleBarCodeRead = (e) => { setBarCode(e.data); };
useEffect(() => { if (barCode !== '') { // Your code here, for example: // navigate to a new screen and pass the barCode value } }, [barCode]);
return ( <View style={styles.container}> {device && ( <Camera style={StyleSheet.absoluteFill} device={device} onBarCodeRead={handleBarCodeRead} > <BarcodeMask /> </Camera> )} {barCode && ( <View style={styles.overlay}> <Image source={require('./path/to/warning/image.png')} style={styles.warningImage} /> <Text style={styles.warningText}>Barcode Scanned: {barCode}</Text> </View> )} </View> ); };
const styles = StyleSheet.create({ container: { flex: 1, }, overlay: { position: 'absolute', top: 0, left: 0, right: 0, bottom: 0, backgroundColor: 'rgba(0, 0, 0, 0.5)', justifyContent: 'center', alignItems: 'center', }, warningImage: { width: 40, height: 40, }, warningText: { color: 'white', fontSize: 16, marginTop: 20, }, });
export default CameraScreen;
Hey - sorry but I read the crash logs again and there is nothing related to VisionCamera. You can try uninstalling VisionCamera and probably get the same error.
This is due to something stripping away native libraries (probably ProGuard)
We solved the issue by applying the dexguard rules below:
-keepresourcefiles lib/**/libfb*.so,lib/**/libreact*.so,lib/**/libyoga*.so,lib/**/libhermes.so,lib/**/libhermes_executor.so,lib/**/libjsi*.so,*/lib/**/libfb*.so,*/lib/**/libreact*.so,*/lib/**/libyoga*.so,*/lib/**/libhermes.so,*/lib/**/libhermes_executor.so,*/lib/**/libjsi*.so
