.NET for Android error XA4307
The Proguard
MSBuild task encountered a ProGuard configuration file
that it could not parse. These files are generally declared in your
.NET for Android project with a build action of
ProguardConfiguration
. However, .NET for Android also generates
ProGuard configuration files internally during the build process.
To learn more about ProGuard and how it relates to Android development, see the Android documentation or the ProGuard website.
Verify you are not declaring a ProguardConfiguration
build item that
contains valid entries. This can also be caused by the config file
containing a Byte Order Mark (BOM) at the start of the file. If this
is the case remove the BOM or save the file using ASCII encoding.
Consider submitting a bug if you are getting this error under normal circumstances.
