Android配置

安装： yarn add rn-fetch-blob@0.10.15 --save

import RNFetchBlob from 'rn-fetch-blob';

/*低版本解决方案添加下面权限

import {PermissionsAndroid}  from 'react-native';
  _crequestMultiplePermission = async () => {
    try {
      const permissions = [PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE];
      const granteds = await PermissionsAndroid.requestMultiple(permissions);
      if (granteds['android.permission.WRITE_EXTERNAL_STORAGE'] === 'granted') {
        this.storage = true;
      } else {
        this.storage = false;
      }
      if (this.storage) return;
    } catch (err) {
      console.log(err);
    }
  };

遇到的问题以及解决办法

Android 9 上无法使用android.actionViewIntent自动安装应用

解决办法：
1、 修改 node_modules/rn-fetch-blob/android/src/main/java/com/RNFetchBlob/RNFetchBlob.java
将 intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
替换为intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_NEW_TASK);

2、然后修改自己项目的AndroidManifest.xml增加

<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />

IOS配置

yarn add rn-app-upgrade --save

// 低于0.6+版本
react-native link rn-app-upgrade

将node_modules/ios_upgrade里面的文件拷贝到项目的IOS目录下
打开Xcode将这两个文件导入项目工程----->点击右键 Add filfe…
