推荐答案

你可以像这样使用 PackageManager 类访问 APK 的签名签名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());
}

我已使用它与我的调试密钥的哈希码进行比较，以识别 APK 是调试 APK 还是发布 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.
