My function when I click on my update Button
private async Task update()
{
this.popupIsVisible = false;
this.IsBusy = true;
string uri = "myLink.apk";
HttpClient cli = new HttpClient();
await cli.DownloadBasicFile(uri, DependencyService.Get<IDeviceDependency>().GetExternalAPKPath());

And my InstallApk() function ( I'm sure that the file is downloaded )
public void InstallApk()

}
catch (Exception e) { Console.WriteLine(e.Message); }
return "";
}

At first, you can check the apk file you had downloaded has any damage. And then you can try to the following steps to install the apk:
1.Add the provider in the AndroidManifest.xml, such as:
<application android:allowBackup="true" android:icon="#drawable/androidicon" android:label="#string/app_name" android:supportsRtl="true" android:theme="#style/AppTheme">
<provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.provider" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/provider_paths" />
</provider>
</application>
2.Create the provider_paths.xml in the folder named xml below the values folder in the android part.
<paths >
<external-path
name="external_files"
path="." />
</paths>
3.Use the following code to install the apk:
var path = Path.Combine(Android.App.Application.Context.GetExternalFilesDir("").AbsolutePath, "com.MyCompany.clamexdroid.apk");
Java.IO.File file = new Java.IO.File(path);
Intent install = new Intent(Intent.ActionView);
Android.Net.Uri apkURI = FileProvider.GetUriForFile(this, this.ApplicationContext.PackageName + ".provider", file);
install.SetDataAndType(apkURI, "application/vnd.android.package-archive");
install.AddFlags(ActivityFlags.NewTask);
install.AddFlags(ActivityFlags.GrantReadUriPermission);
StartActivity(install);

handshakeexception handshake error in client (os error wrong_version_number tls_record cc 242) Flutter app/Node server

I'm getting an handshakeexception handshake error in client (os error wrong_version_number tls_record cc 242) error whenever making an http request( I also tried https ) but from only one ( Cyclist app ) of the two Flutter apps that connect to Node.js server. I'm using the same IP address and port on both, the Android tablet on which I'm testing both apps and for my machine. I checked Manifest Android/src/main/AndroidManifest.xml to see if I was using android:usesCleartextTraffic="true"`on the working app ( Shop app ) but I'm not..
What else could I check to see what's causing the error in the Cyclist app??
This is the request:
Map<String, String> headers = {
'Content-Type': 'application/json',
'api_key': Environment.dbApiKey
};
// final Uri uri = Uri.https(Environment.dbUrl, '/api/routes');
final Uri uri = Uri.http(Environment.dbUrl, '/api/routes');
await post(uri, headers: headers, body: jsonEncode(route.toMap()))
.then((resp) {
print(
'RouteMongoRepository.saveRoute response status code is: ${resp
.statusCode}, \n response is : ${jsonDecode(resp.body)}');
UserRoute saved = UserRoute.fromMap(jsonDecode(resp.body)['data']);
print('saved route to Mongo is : ${saved.toMap().toString()}');
}) .catchError((e) => print('RouteMongoRepository.saveRoute error: $e')) ;
This is the Shop app manifest:

Found it..I was missing <uses-permission android:name="android.permission.INTERNET" />in Cyclist app AndroidManifest.xml

Notification is received but not displayed using Parse Unity SDK + Android

I'm using Parse Unity SDK for Android.
I've managed to register the device successfully.
void Start() {
//Parse Installation
if (ParseInstallation.CurrentInstallation != null && !string.IsNullOrEmpty(ParseInstallation.CurrentInstallation.DeviceToken))
{
Debug.Log("Device Token : " + ParseInstallation.CurrentInstallation.DeviceToken);
}
else
{
ParseInstallation installation = ParseInstallation.CurrentInstallation;
installation.Channels = new List<string> { Config.Instance.GetUserInfo().GetEmail() };
installation.SaveAsync().ContinueWith(t => {
if (t.IsFaulted || t.IsCanceled)
{
Debug.Log("Push subscription failed.");
}
else
{
Debug.Log("Push subscription success.");
}
});
//installation.
}
}
Only to discover that the notification is "received" but not being displayed neither in the app nor in the notifications bar.
I/GCM ( 1285): GCM message com.ahmed.app 0:1433935471473270%3f8fc5dbf9fd7ecd
I/ParsePushService( 7057): Push notification received. Payload: {"alert":"test","push_hash":"098f6bcd4621d373cade4e832627b4f6"}

W/GCM-DMM ( 1285): broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.ahmed.app (has extras) }
Also, Unity does not receive the notification (see code)
void Awake() {
ParsePush.ParsePushNotificationReceived += (sender, args) => {
#if UNITY_ANDROID
AndroidJavaClass parseUnityHelper = new AndroidJavaClass("com.parse.ParseUnityHelper");
AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
//Debugging the payload
Debug.Log("Calling Parse from Unity and Payload is : " + args.StringPayload);
// Call default behavior.
parseUnityHelper.CallStatic("handleParsePushNotificationReceived", currentActivity, args.StringPayload);
#endif
};
}
This event doesn't get triggered.

Any idea what's the problem?

I have answered the same kind of question, I just wanted to let you know.
Parse Unity Push Sample not working
Basically, this line of your code is wrong:
AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
You have to replace it by
AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("com.unity3d.player.UnityPlayerNativeActivity");

Rather than downloading the SDK manually, I've downloaded the Parse Push sample project and copied the files to my project. Using the SDK 1.5.2 sample project, it works now.

RECEIVE_BOOT_COMPLETED does not work

I am trying to write in file after android device boots. I have checked everything related to this topic here but none of them worked for me. My phone is Huawei Honor (H30-U10) and it's rooted. Android version 4.2.2. Here is my code:
AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="bog.ddrc.technicianmobile"

android:name="bog.ddrc.technicianmobile.StartTMServiceAtBootReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
StartTMServiceAtBootReceiver.java:
public class StartTMServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String data = "text";
File path = Environment.getExternalStorageDirectory();
File file = new File(path, "test.txt");
try {
OutputStream os = new FileOutputStream(file);
os.write(data.getBytes());
os.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

Remove
android:permission="android.permission.RECEIVE_BOOT_COMPLETED"
from your <receiver> block.

After trying all of mentioned answers and tricks, I finally find why the code is not work in my phone. Some Android phones like "Huawei Honor 3C Android 4.2.2" have a Statup Manager menu in their settings and your app must be checked in the list. :)

Creating Android Native Extension and getting: Permission Denial: starting Intent.. on second activity

I am successfully calling my first Activity from my AIR Native Extension, however, when I try to call the second one, I am getting the Permission Denial error (see logcat screenshot). I have tried everything I have found suggested on this site, so posting question.

</application>
Things to note:
I first tried AddMarkerActivity without any intent-filter defined. Not having ANY luck, I began experimenting with the RUN action. I have commented everything out in AddMarkerActivity except for one logcat message that says "HELLO" in the onCreate method. As you can see my Activity is not duplicated in the manifest and exported is set to true.
And finally, here is how I am calling the Activity:
public class AddAnnotationFunction implements FREFunction {
public static final String TAG = "AddAnnotationFunction";
public final static String EXTRA_MARKER = "com.cno.nativemap.functions.marker";
#Override
public FREObject call(FREContext context, FREObject[] args) {
Intent intent = new Intent();
intent.setClassName("com.cno.android.map", "com.cno.android.map.AddMarkerActivity");
Log.d(TAG, "Starting Map Activity- add marker");
intent.setAction("android.intent.action.RUN");
intent.putExtra(EXTRA_MARKER, new GeoMarker(args));
context.getActivity().startActivity(intent);
return null;
}
}
