【问题描述】:
从我的 Phonegap 应用程序中,我正在下载我的 APK,这没有问题,但我无法安装该文件。
以下代码在 WEB INTENT 部分失败,应该安装 APk,但读取文件时遇到问题。
var apkFilePath = cordova.file.externalApplicationStorageDirectory+'myapp.apk';
// Android UPDATE routine
function downloadApkAndroid(data) {
var permissions = cordova.plugins.permissions;
permissions.hasPermission(permissions.WRITE_EXTERNAL_STORAGE, function (status) {
if (!status.hasPermission) {
var errorCallback = function () {
alert("Error: app requires storage permission");
if (callBack && callBack !== null) {
callBack();
}
};
permissions.requestPermission(permissions.WRITE_EXTERNAL_STORAGE,
function (status) {
if (!status.hasPermission)
errorCallback();
else {
downloadFile();
}
},
errorCallback);
}
else {
downloadFile();
}
}, null);
}
function downloadFile(){
var fileTransfer = new FileTransfer();
var url = "https://myappurl.com/myapp.apk";
var uri = encodeURI(url);
var filePath = getFilePath();
fileTransfer.download(
uri,
apkFilePath,
function (entry) {
console.log("Download complete: " + entry.fullPath);
promptForUpdateAndroid(entry);
},
function (error) {
console.error("Download error source " + error.source);
console.error("Download error target " + error.target);
console.error("Download error code " + error.code);
},
false,
{
}
);
}
/*
* Uses the borismus webintent plugin
*/
function promptForUpdateAndroid(entry) {
console.log(apkFilePath);
window.plugins.webintent.startActivity(
{
action: window.plugins.webintent.ACTION_VIEW,
url: apkFilePath,
type: 'application/vnd.android.package-archive'
},
function () {
},
function () {
// alert('Failed to open URL via Android Intent.');
console.log("Failed to open URL via Android Intent. URL: " + entry.fullPath);
}
);
}
