Is there a way to retrieve the signature of the key used to sign an APK? I signed my APK with my key from my keystore. How can I retrieve it programmatically?

推荐答案

您可以使用PackageManager类访问APK的签名 http://developer.android.com/reference/android/content/pm/PackageManager.html

You can access the APK's signing signature like this using the PackageManager class http://developer.android.com/reference/android/content/pm/PackageManager.html

Signature[] sigs = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_SIGNATURES).signatures;
for (Signature sig : sigs)
{
    Trace.i("MyApp", "Signature hashcode : " + sig.hashCode());
}

我已将其与调试密钥的哈希码进行比较，以此来确定APK是调试APK还是发行版APK.

I've used this to compare with the hashcode for my debug key, as a way to identify whether the APK is a debug APK or a release APK.
