AndroidNativeLibrary not getting picked in Release mode.

prabhav-mehra commented 1 year ago

Android application type

.NET Android (net7.0-android, etc.)

Affected platform version

VS 2022 17.7.4, Maui 7.0.92

Description

AndroidNativeLibrary/.so file is not getting picked in release mode but works in debug mode.

I am using a library which requires android native libraries to work. I have build the .so files and added to libs/{ABI} and these are getting picked in Debug mode and the functioality works. on Release mode I get dll not found for the same library.

Steps to Reproduce

Clone the public repo.
Push the ".heic" image from the repo to your android device to downloads folder.
Open solution from libheif-sharp -> src -> LibHeifSharp.sln which has reference to all necessary projects.
Run MauiApp1 on an Android device with Debug mode.
Click the button and select the "heic" image from your downloads folder.
This will process the image and will allow you to save it as a "png" file.

This works on Debug mode but will fail with libheif dll not found on Release mode.

I guess adding the following in your csproj solves the issue. But I dont know why? I know useInterpreter is set to true by default for Debug for Hot Reload but I can't understand how this is linked with my case.

<UseInterpreter>True</UseInterpreter>
<MtouchProfiling>True</MtouchProfiling>

Can you check to see if the libde265.so and libheif.so are making it into the aab file? Also which device are you running this on , specifically which abi is it (x86, x86_64, armeabi-v7a or arm64-v8a).

@dellis1972 How do you check if the files are being included in .aab? also I am pretty sure it's not being included in Release mode without these enteries https://github.com/xamarin/xamarin-android/issues/8363#issuecomment-1733012862. As if it would have, it wouldn't say dll not found.

I am testing it on arm64-v8a and both WSA

@s3743761

The aab file is just a zip file, you can rename the file to .zip and then extract all the contents. The libraries folders should be in the base folder.

prabhav-mehra commented 1 year ago

@dellis1972 Yes they are being included.

@s3743761 it might then be worth checking the dependencies of the .so files. One of the reasons a .so fails to load is if its compiled against library or other .so which cannot be found, you might be either missing a .so file or it was compiled against a library which is not present on the device... that said why it would work in debug but not release does kinda mean it is finding the dependencies. But it would be good to rule that out.

@grendello do you know the best way to check dependencies on android based .so files?

grendello commented 1 year ago

It would require the presence of NDK (or command line compiler tools on macOS) so that the llvm-readelf binary is available:

$ llvm-readelf --needed-libs ./bin/Debug/dotnet/packs/Microsoft.NETCore.App.Runtime.Mono.android-x64/8.0.0-rc.2.23466.4/runtimes/android-x64/native/libmonosgen-2.0.so
NeededLibraries [
  libc.so
  libdl.so
  liblog.so
  libm.so
  libz.so
]

llvm-readelf can be found in the Android NDK, in the $NDK_ROOT/toolchains/llvm/prebuilt/$OS-$ARCH/bin/ directory

how does that change between a release and debug version? because the same app works in debug but not release

@prabhavmehra I tested your sample on my dotnet 7 install against an arm emulator and it works ok .

@dellis1972 can you try it on an physical device if possible or WSA. I didn't try it to emulator

dellis1972 commented 1 year ago

The sample worked on my Pixel 4

Fixed similar issue by adding

<AndroidBundleConfigurationFile>BundleConfig.json</AndroidBundleConfigurationFile>

into project PropertyGroup

and adding BundleConfig.json file with

{
"optimizations" : {
"uncompress_native_libraries" : {}
}
}

Thanks bro, that fixed a similar issue in my project in which i did a "Jar binding" of a 3rd party library (an android manufacturer gave me .jar files with a SDK for their hardware). i was only running in debug.
