[RadoslawKubas]

Description

After upgrade from Xamarin.Forms 4.4.0.991640 to 4.5.282-pre4 I noticed that when

<BundleAssemblies>True</BundleAssemblies>

app crash on start with exception

System.IO.FileNotFoundException: Could not load file or assembly 'Xamarin.AndroidX.AppCompat.Resources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

My working setup for release in 4.4 is

<AndroidLinkMode>Full</AndroidLinkMode>
<AotAssemblies>True</AotAssemblies>
<AndroidEnableProfiledAot>false</AndroidEnableProfiledAot>
<EnableLLVM>True</EnableLLVM>
<BundleAssemblies>True</BundleAssemblies>

in 4.5 everything works fine only if

<AndroidLinkMode>Full</AndroidLinkMode>
<AotAssemblies>True</AotAssemblies>
<AndroidEnableProfiledAot>false</AndroidEnableProfiledAot>
<EnableLLVM>True</EnableLLVM> 
<BundleAssemblies>False</BundleAssemblies>

Steps to Reproduce

1. Create new solution
2. Upgrade Xamarin to 4.5.0.282-pre4
3. Set:

<AndroidLinkMode>Full</AndroidLinkMode>
<AotAssemblies>True</AotAssemblies>
<AndroidEnableProfiledAot>false</AndroidEnableProfiledAot>
<EnableLLVM>True</EnableLLVM>
<BundleAssemblies>True</BundleAssemblies>

5. Run app on the real device

App starts.

Actual Behavior

App crash with System.IO.FileNotFoundException exception.

@RadoslawKubas Could you attach an example or review the attached one?
Issue9689.zip
I can't reproduce it. I am using Xamarin.Forms 4.5-pre4 and:

<AndroidLinkMode>Full</AndroidLinkMode>
<AotAssemblies>True</AotAssemblies>
<AndroidEnableProfiledAot>false</AndroidEnableProfiledAot>
<EnableLLVM>True</EnableLLVM>
<BundleAssemblies>True</BundleAssemblies>

I can reproduce it in release mode only

[danardelean]

I had/have the same problem and it is only in Release mode.
Tried disabling Xamarin.AndroidX.AppCompat for the linker but I still got the problem.

Another problem with AndroidX (the stable versions) and XF 4.5 pre-release is that you cannot enable r8 (code shrinker) in release.

In the end I rolled back to the old support libraries and everything works.

@danardelean can you be more specific about the error you are seeing? Please open a new issue with more details.

[RadoslawKubas]

I checked with latest stable 4.5.0.356 and same problem repeats. I tried to prepare an example, but the problem is that even in my main solution, I can't reproduce it locally. When building same commit with VS2019 Community 16.4.5 it seems to be fine, but with build on Microsoft App Center and publish to Google Play, all prepunch tests fails.

I am having the exact same issue. On DEBUG everything works fine. If I change the config to Release - the build passes, I can archive the app but as soon as the app starts, the app crashes with the same error.

[mduchev]

Okay, so I managed to produce a sample project and I managed to narrow down the problem, but this time I got a different exception (but at the same time it is kind of similar). It turned out that it isn't due to the BundleAssemblies config. This happens as soon as we choose to use r8 for code shrinking, the app crashes.

Here is the demo project:
DemoAndroidXCrash.zip

Steps to reproduce:

1. Open the solution
2. Build the app in Release config
3. Archive & Distribute it with a whatever signing identity you wish
4. Install the signed apk into a phone
5. Run the app

If we don't have any code shrinking, everything works fine and the app launches successfully. However, if we choose to use code shrinking (and r8 specifically), then the app crashes with the following exception:

Here is another repro project:
TestAndroidX.zip

In debug mode, an image will be displayed on the main page.
In release mode, the image is not displayed, because of the exception.

The exception is only happening with <BundleAssemblies>True</BundleAssemblies>.
It makes no difference whether R8 or Linker are enabled or not.
I'm using XF 4.5.0.
This exception can be easily reproduced on the emulator.

Stack trace of the exception (no crash, it's silent):
ImageElementManager: Error loading image: System.IO.FileNotFoundException: Could not load file or assembly 'Xamarin.AndroidX.AppCompat.Resources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

I have same problem

[tranb3r]

Similar to #45 (which has been closed).
@moljac Could you please take a look ? This is quite serious...

[ognamala]

We have also observed this problem, which happens only in release mode and when Bundle Assemblies is set to true

[nhdanh]

Will fix on new version ?
