我真的觉得我得到了正确的哈希键，因为：
I do really think I got the right Hash-key because:
public static String getKeyHash(Context context) {
String returner = "";
try {
PackageInfo info = context.getPackageManager().getPackageInfo(
"com.lochmann.fb.viergewinntmultiplayer", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
returner = Base64.encodeToString(md.digest(), Base64.DEFAULT);
Log.e("MY KEY HASH:",
Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
e.printStackTrace();
Log.e("ERROR", "NO NAME");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
Log.e("ERROR", "NO ALGO");
}
return returner;
}
收益十一月11日至11日：10：42.445：E /我的钥匙HASH：（19215）：2jmj7l5rSw0yVb / vlWAYkK / YBwk =
returns 11-11 11:10:42.445: E/MY KEY HASH:(19215): 2jmj7l5rSw0yVb/vlWAYkK/YBwk=
我在FB后端设置是这样的：
My Settings in the FB Backend look like this:
有谁有我一个提示，我做错了还是什么我可以试试吗？
Does anybody have a hint for me, what I am doing wrong or what i could try?
先谢谢了。
推荐答案
如果你调用该方法出来活动，它总是返回错键的哈希[2jmj7l5rSw0yVb / vlWAYkK / YBwk =]。尝试打印您的活动（OnCreate中）。居然不知道为什么，但它为我工作。希望这可以帮助别人。
if you call that method out of activity, it returns always wrong key hash [2jmj7l5rSw0yVb/vlWAYkK/YBwk=]. Try to print it in your activity(oncreate). Actually don't know why, but it works for me. Hope to this helps someone..
