Summary: Opening a Local File - breaking on cordova.js
Key: CB-12894
URL: https://issues.apache.org/jira/browse/CB-12894
Project: Apache Cordova
Issue Type: Bug
Environment: DevExtreme SPA Application using Cordova
Reporter: Kyle Slack
Priority: Critical
We have an application that has a self updating feature, we do not host in the
Google Play Store, however, we host it for our users. We have had success with
previous versions of our application, but recently on newer devices running
Android 6.0 or higher our users are running into an error when trying to open
the downloaded .apk file that should provide our users with an updated version
of the app prompted for installation. On Android 6.0 or lower everything is
working perfectly fine with the following code. Lastly, we were able to debug
this to the point where we can see the file is actually downloading fine, and
only the call to open the file throws an exception. We were able to debug down
into the cordova.js file and found that there was an exception occurring when
the fileOpener2 plugin performs it's open() callback, but seems like this is
related to Cordova and not anything to do with the fileOpener2, we have already
discussed this with the developer.
Test Device Info: Motorola Turbo 2 / Android 7.0
Exception Msg: 230 F09 FileOpener21362683899 sAttempt to invoke virtual method
'android.content.res.XmlResourceParser
//android.content.pm.PackageItemInfo.loadXmlMetaData(android.content.pm.PackageManager,
java.lang.String)' on a null object reference
Code:
// we need to access LocalFileSystem
window.requestFileSystem(LocalFileSystem.PERSISTENT, 5 * 1024 * 1024,
function (fs) {
//Show user that download is occurring
$("#toast").dxToast({
message: "Downloading please wait..",
type: "warning",
visible: true,
displayTime: 20000
});
// we will save file in .. Download/OURAPPNAME.apk
var filePath = cordova.file.externalRootDirectory + '/Download/' +
"OURAPPNAME.apk";
var fileTransfer = new FileTransfer();
var uri = encodeURI(appDownloadURL);
fileTransfer.download(uri, filePath, function (entry) {
//Show user that download is occurring/show user install is
about to happen
$("#toast").dxToast({
message: "Download complete! Launching...",
type: "success",
visible: true,
displayTime: 2000
});
////Use pwlin's fileOpener2 plugin to let the system open the
.apk
cordova.plugins.fileOpener2.open(
entry.toURL(),
'application/vnd.android.package-archive',
{
error: function (e) {
window.open(appDownloadURL, "_system");
},
success: function () { console.log('file opened
successfully'); }
}
);
},
function (error) {
//Show user that download had an error
$("#toast").dxToast({
message: error.message,
type: "error",
displayTime: 5000
});
},
false);
})
Problem File: cordova.js
THIS IS ALL NOT OUR CODE, BUT 'CORDOVA' CODE
function androidExec(success, fail, service, action, args) {
// argsJson -
"["file:///storage/emulated/0/download/OURAPPNAME.apk","application/vnd.android.package-archive"]"
//callbackId - FileOpener21362683899
//action - open
//service FileOpener2
//bridgesecret - 1334209170
var msgs = nativeApiProvider.get().exec(bridgeSecret, service, action,
callbackId, argsJson);
// If argsJson was received by Java as null, try again with the PROMPT
bridge mode.
// This happens in rare circumstances, such as when certain Unicode
characters are passed over the bridge on a Galaxy S2. See CB-2666.
if (jsToNativeBridgeMode == jsToNativeModes.JS_OBJECT && msgs === "@Null
arguments.") {
androidExec.setJsToNativeBridgeMode(jsToNativeModes.PROMPT);
androidExec(success, fail, service, action, args);
androidExec.setJsToNativeBridgeMode(jsToNativeModes.JS_OBJECT);
} else if (msgs) {
messagesFromNative.push(msgs);
// Always process async to avoid exceptions messing up stack.
nextTick(processMessages);
}
// msgs = "230 F09 FileOpener21362683899 sAttempt to invoke virtual method
'android.content.res.XmlResourceParser
//android.content.pm.PackageItemInfo.loadXmlMetaData(android.content.pm.PackageManager,
