Question

我尝试从ionic4的https://github.com/pwlin/cordova-plugin-file-opener2的“快速示例”中进行“打开安装对话框”

这是我的代码：

进口：

import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer/ngx';
import { FileOpener } from '@ionic-native/file-opener/ngx';
import { File } from '@ionic-native/file/ngx';

下载并打开文件：

const fileName = 'last.apk';
const fileMime = 'application/vnd.android.package-archive';

//const fileName = 'last.pdf';
//const fileMime = 'application/pdf';

const downloadLink = me.settings.api.bin + fileName;

const basePath = me.file.externalDataDirectory; //dataDirectory, externalApplicationStorageDirectory
const downloadPath = 'apk';

me.file.createDir(basePath, downloadPath, true).then(function(link) {

    const savePath = basePath + downloadPath + '/' + fileName;
    const fileTransfer: FileTransferObject = me.transfer.create();

    fileTransfer.download(downloadLink, savePath).then((entry) => {
        me.fileOpener.open(entry.toURL(), fileMime)
            .then(() => console.log('File is opened'))
            .catch(e => console.log('Error opening file', e));
    }, (err) => {

    });

});

工作正常，PDF已下载并打开。

APK失败，文件下载成功，并且文件打开器显示“文件已打开”，但窗口未出现安装对话框，这是什么问题？

我找到了解决方案，将此行添加到config.xml

<config-file parent="/manifest" target="AndroidManifest.xml" xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
</config-file>

Ionic4 fileOpener插件无法打开下载的.apk文件
