jimmypun610 / plugin.xf.appinstallhelper Goto Github PK

Hi Jimmy~ Excellent work, we all appreciated that! Here we encountered a little problem:

When attempting to install on Android 10 devices,
An error showed up:
Java.Lang.NullPointerException: 'Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference'

The code is as follows:
string apkPath = "file:///storage/emulated/0/Download/AppName.1.0-8.apk";
await Plugin.XF.AppInstallHelper.CrossInstallHelper.Current.InstallApp(apkPath, Plugin.XF.AppInstallHelper.Abstractions.InstallMode.OutOfAppStore);

Anything we are doing wrong? Please help. Thanks~

Hi Jimmy,
The AppInstallHelper is great. It simplifies the code of updating app packages. Thanks a lot.
Are there any plan of releasing a version which works with MAUI preview (the enhancement version of Xamarin)?

Best Regards,
Sunshine

var canRequestInstallPackage = true;

Hi Jimmy,
I tried to set the file_paths.xml's "Build Action" as instructed by your readme documentation, but there is no such option as "AndroidResource" in the dropdown list, and manually setting this string causes a popup error -- "An error has occurred while saving the edited properties listed below: Build Action. One or more values are invalid. The item type 'AndroidResource' is not supported by this project item provider."

 I also checked your maui demo project, your project actually has this "AndroidResource" option. Weird. Are there any workarounds about this issue?  Environment: the latest VS preview / MAUI / Windows11 version.

 Thanks.
 Best Regards

Hello, first thanks for the great idea, and now I'm not able to get my test-project running.
I use VS2017, And the dependencies I attached as an image. Can you provide help, or a sample project, so I can compare? Thank's a lot!
With best regards, Thomas.

Hi, i am using this to install a newer version of the app, but everytime the installer run, it always gives me "Parse error: There is a problem parsing the package" any idea?

Hi Jimmy,
UWP support of specifying path to download and installing the app package can be done by the following platform specific code.
I tried to integrate this into your source code to support Windows platform, but haven't figured it out.
Is it possible for you to integrate this code into this wonderful AppInstallHelper?

//---------UWP code (Tested)
using Applicat.Common;
using Applicat.UWP;
using System;
using System.IO;
using System.Threading.Tasks;

[assembly: Xamarin.Forms.Dependency(typeof(Update))]
namespace Applicat.UWP
{
public class Update : IUpdate
{
public string SpecifyFilePath(string fileName)
{
return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), fileName);
}

    public async Task<bool> Install(string stringUri)
    {
        try
        {
            return await Windows.System.Launcher.LaunchUriAsync(new Uri("ms-appinstaller:?source=" + stringUri));
        }
        catch (Exception ex)
        {
            return false;
        }
    }
}

}
