Announced today, the new emulator for android development

Note: The installer wants to install virtual box, so I am guessing it is similar to genymotion.

I am failing miserably to use Camera2 API. All I need to do is simply show the camera output on the screen and work the image in the background. So far I can not even connect to camera - I can't even understand how to use OpenCamera method of CameraManager. Does anyone have an example? Please do not advice official Camera2Basic example - it has little to no comments and of little help.

So you just finished developing your app, you’d like to test it, and so you start distributing it to your users or testers, they discover bugs in your app, but the feedback process is tedious, and never gives you enough data. This is what Instabug exactly is for. Instabug's SDK provides you with an intuitive bug and crash reporting solution. you find a bug, shake the phone, Instabug pops up with a screenshot that you can draw on, then hit send. You'll then get complete device details, network logs, and visual steps the user has taken so you can reproduce the bug. Crash reports are also sent to you automatically whenever a crash occurs along with complete stack trace so you could know exactly which line is causing the app to crash.

If you use (or are planning) to use the Xamarin IAP component.,it has a pretty major bug in the Security.Unify() call.

The documentation states:

the first parameter is an array of strings containing your private key broken into two or more parts in a random order. The second parameter is an array of integers listing of order that the private key parts should be assembled in.

So the following code:

Security.Unify(
    new string[]
    {
        "rjp8zp6tD2", "CJlI/erEF5", "rFCIU8Gj7n", "8AMIIBCgKC", "wccUuknUCu"
    },
    new int[]
    {
        1, 4, 2, 3 ,0 
    }
);

Should produce "wccUuknUCurjp8zp6tD2rFCIU8Gj7n8AMIIBCgKCCJlI/erEF5", but it produces "CJlI/erEF5wccUuknUCurFCIU8Gj7n8AMIIBCgKCrjp8zp6tD2"

The reason for this is that the index array is used to correctly get the desired segment, but then the function uses string.concat to place the segments in the wrong order in the output string.

(decopiled function)

public static string Unify(string[] element, int[] segment)
{
    string empty = string.Empty;
    int[] numArray = segment;
    foreach (int num in numArray)
    {
        empty = string.Concat(empty, element[num]);
    }
    return empty;
}

It's clear that this function has not been tested with anything other that the order "0,1,2,3" (from the sample code).

I solved this by creating my own custom replacement for Unify(), which actually obeys the stated behaviour.

Bugzilla Entry

What i want is an open source Obfuscar software like the title says.

Something like `Phoenix Protector` would be very good

The problem with `Phoenix Protector` is that its not really working with xamarin and android.

Dotfuscator is the best i found until now that work with xamarin, but the free version lack the command line and i want to use it via command line so i could build a `UserTask` with `visual studio 2019`

Is there a free opensource that work with xamarin android, and also able to obscrate via command line?

Im a free user and i really dont want to buy a license, so please tell me your opinion.

This is an example of how i used `Phoenix Protector` and the dll get obscrate but the app crash

var args = $"-p \"{settingsPath}\" \"{dllDirNew}\" {(StayOpen ? "/K" : "")}";

var process = new Process

{

StartInfo = new ProcessStartInfo()

{

Arguments = args,

FileName = name,// Phoenix Protector

WorkingDirectory = applicationPath, // Phoenix Protector directory

WindowStyle = Hidden ? ProcessWindowStyle.Hidden : ProcessWindowStyle.Normal

}

};

I also used `Skater .NET Obfuscator` but its not really as good as `Phoenix Protector` and also i cant use `Progaurd` which i really would need to.

The program need to be

1- Able to hide or encrypt all `strings` this is a very importend requirement for me.

2- support a command line.

3- only generate a single dll

Hey everyone, I just started using Xamarin yesterday and was curious where to start as a beginner. I know basic C# but know nothing about making apps let alone android apps. Another thing to note is I’m creating an app for a summer project for school and have 6 weeks give or take. Thanks In advance!
