Open downloaded file

[davorpeic]

Hi,

do you know how I could open downloaded file on android, I successfully download new apk version of the app and I would like to open it once its done, I tried doing custom intents, but I couldn't get it working.

thanks

Ok, we added feature to open downloaded file once it is downloaded in Android, are you interested in PR?

Sorry for missing the previous comment. Actually yes. It works on android 7+? I know they pretty much broke creating intents from a file.

Good question, we have tried it only on android 5 & 6, will try and let you know.

Probably it wont work if you haven't adjusted it for N+ and theres almost no docs about it. Just managed to do it (opening an apk to install), i'll release it on an app i want to update and make open source before xmas. But if you can manage with ugly/hacky vanilla js here's a "preview".

Not sure how to integrate this easily inside this package tbh. Switched to react native so i haven't touched ns nor ts for a while.

                var loader = new LoadingIndicator();        
                loader.show();                      
                this.ndm.downloadFile(url, {}, ((res, path) => {
                    loader.hide();                
                    if (res) {
                        console.log(path);
                        var myuri = undefined;                                       
                        if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.M){
                            var o = new java.io.File(path.replace("file://",""));
                            o.setReadable(true, false);
                            var con = Application.android.foregroundActivity;                    
                            myuri =  android.support.v4.content.FileProvider.getUriForFile
                                (con, "com.tns.NativeScriptApplication.fileprovider", o);
                        } else {
                            myuri = android.net.Uri.parse(path);
                        }

                        var promptInstall = new android.content.Intent(android.content.Intent.ACTION_VIEW).setDataAndType(myuri,"application/vnd.android.package-archive");
                        if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.M){
                            var resolvedIntentActivities = Application.android.foregroundActivity.getPackageManager().queryIntentActivities(promptInstall, android.content.pm.PackageManager.MATCH_ALL);
                            var size = resolvedIntentActivities.size()
                            for (var i = 0; i < size; i++) {
                                var resolvedIntentInfo = resolvedIntentActivities.get(i);
                                var packageName = resolvedIntentInfo.activityInfo.packageName;
                                Application.android.foregroundActivity.grantUriPermission(packageName, myuri, android.content.Intent.FLAG_GRANT_WRITE_URI_PERMISSION | android.content.Intent.FLAG_GRANT_READ_URI_PERMISSION);
                            }
                        }                        
                        Application.android.foregroundActivity.startActivity(promptInstall);
                    } else {
                        this.showError("Download has failed, please ensure you have internet access");
                    }

                }).bind(this)); 

You will also need to create a fileprovider on the manifest.xml file.

        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.tns.NativeScriptApplication.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/filepaths" />
        </provider>

and create another xml file with the filepaths.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="files" path="files/"/>
    <external-files-path name="downloads" path="downloads/"/>
</paths>

Also in Oreo it will fail silently unless you add this permission.

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