使用 MSBuild 命令行错误创建 APK（PackageForAndroid 或 SignAndroidPackage）

Question

So I have been trying to create an APK in Release mode using the MSBuild command line executable.

Here is the contents of my batch file which I created:

ECHO Building DsdMobile Solution... >CON
cd "C:\Ross\DEVELOPMENT\HANDHELD\Android\Dsd Mobile MaterialDesign"

"C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" DsdMobile.sln /P:Configuration=Release /v:quiet /t:Clean /nologo

"C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" DsdMobile.sln /P:Configuration=Release /v:quiet /t:Rebuild,PackageForAndroid /nologo

The first line I change the directory to my solution location. Next, I do a Clean

Last, I do a Rebuild and PackageForAndroid (which I am expecting a...apk file in my bin release folder. An apk is never created and I get an error.

The build is successful, but I get an error:

"C:Ross\Development\Handheld\Android\Dsd Mobile MaterialDesign\DsdMobile.sln.metaproj : error MSB4057: The target "PackageForAndroid" does not exists in the project. [C:\Ross\DEVELOPMENT\HANDHELD\Android\Dsd Mobile MaterialDesign\DsdMobile.sln]

I have also tried to use SignAndroidPackage 's :t/ parameter, but this also fails with the same error:

"C:Ross\Development\Handheld\Android\Dsd Mobile MaterialDesign\DsdMobile.sln.metaproj : error MSB4057: The target "SignAndroidPackage" does not exists in the project. [C:\Ross\DEVELOPMENT\HANDHELD\Android\Dsd Mobile MaterialDesign\DsdMobile.sln]

The resource I have been using was from a PowerShell script:

Answer 1

尝试构建Android csproj文件而不是解决方案文件。

Answer 2

You can build the solution, you will need to specify the project and task in the target eg:

.WithTarget("DroidAppProj:SignAndroidPackage")

Here is more documentation: Spoiler-it sux if you have a . in your project name: https://docs.microsoft.com/en-us/visualstudio/msbuild/how-to-build-specific-targets-in-solutions-by-using-msbuild-exe?view=vs-2017

Answer 3

This works just fine for me from Visual Studio 2017 and 2019 command line prompts:

msbuild /t:SignAndroidPackage /p:Configuration=Release Application.Android.csproj

As already noted, build the csproj not the solution.

Answer 4

You can use

/p:AndroidBuildApplicationPackage=true instead of /t:SignAndroidPackage

See Building Process - AndroidBuildApplicationPackage

Answer 5

If you want to build the.sln rather than the.csproj, from the command line, you can do /t:MyAndroidProject:SignAndroidPackage where "MyAndroidProject" == the name of your Android project.

That will apply the target only to the specified csproj rather than trying to execute the target on every solution in the project.
