兄弟 那个版本的?
^2.0.0,现在我用 react-native-camera 官方的 demo + 这个库的 QRScannerRectView
不会闪退了

需要先申请权限,再跳转扫码,否则会因为权限不足报错。你自己加个 react-native-permissions 库判断下应该就好了。

@MarnoDev 请问是判断 PERMISSIONS.ANDROID.CAMERA 吗 判断后在Android模拟器第一次打开正常,但是退出再次打开白屏,并且打包后Android真机闪退,是我判断错误还是需要判断别的权限
import {check, PERMISSIONS, RESULTS, request} from 'react-native-permissions';
check(Platform.OS === 'ios' ? PERMISSIONS.IOS.CAMERA : PERMISSIONS.ANDROID.CAMERA).then(result => {
switch (result) {
case RESULTS.UNAVAILABLE:
console.log('This feature is not available (on this device / in this context)',);
break;
case RESULTS.DENIED:
console.log('开始请求权限');
request(Platform.OS === 'ios' ? PERMISSIONS.IOS.CAMERA : PERMISSIONS.ANDROID.CAMERA).then(result => {
if(result){
this.props.navigation.navigate('Scanner')
}
});
break;
case RESULTS.GRANTED:
console.log('已通过');
this.props.navigation.navigate('Scanner')
break;
case RESULTS.BLOCKED:
console.log('The permission is denied and not requestable anymore');
break;
}
})

QRScanner.js
组件 RNCamera 添加权限
androidCameraPermissionOptions={{
title:'****',
message: '****',
buttonPositive: '****',
buttonNegative: '****',
}}
但是有一个很神奇的现象 连续开关七八次 就闪退了

@weiting918 不闪退吗? 增加 react-native-permissions
插件,不如在 RNCamera 添加权限
