When using Proguard I was getting a VerifyError on SDK 3 when trying to
access the Version.SDK_INT field.
With proguard disabled, everything worked fine because I was using the
standard approach of using a wrapper class to prevent VerifyErrors:
public static int getSdkInt() {
int sdkInt = getSdkIntSafely(); if (sdkInt < 4) { return sdkInt; } else {
return VersionSdkIntWrapperForDonut.getValue(); } } private static int
getSdkIntSafely() { try { return Integer.parseInt(VERSION.SDK); } catch
(Throwable t) { return -1; } }
private static class VersionSdkIntWrapperForDonut {
private static int getValue() {
return VERSION.SDK_INT;
}
}
However, it appears that (using the default Android Proguard config), the
wrapper class was being "optimized" in such a way that this technique no
longer worked.
My current workaround is to specify -dontoptimize which works fine.
Is there a more specific flag to use?
