问题
I have an issue as said in the title of this post. I am unable to login.
SessionState currentstate = session.getState();
gives me a state CLOSED_LOGIN_FAILED. I took a look at this post, Android Facebook SDK 3.0 gives "remote_app_id does not match stored id" while logging in
I generated a key using the keytool and put that in the App Dashboard. But that does not seem to help. Any help on this appreciated
回答1:
call this below method from oncreate of your activity , it will print a hash key in logcat, add that into hash field in app setting on Facebook. try again it will work
public void printHashKey() {
try {
PackageInfo info = getPackageManager().getPackageInfo("your.package.name",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("TEMPTAGHASH KEY:",
Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
}

I know this has already has a selected answer, but it is important to note that if you are trying to use keytool instead of printing the keyhash in code, make sure you use the keytool that comes with java 1.6 instead of java 1.7.
