How to create a Facebook key hash?
android, facebook, facebook-android-sdk
Solution
try
try {
PackageInfo info = getPackageManager().getPackageInfo("com.eatapp", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.e("MY KEY HASH:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
in your main Activity :-) This is the only solution it works for me for Android SDK 3.0
Problem
In the Facebook android tutorial we are told to use following code to create a key hash: keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64 Is this the exact code to use in all situations? For example instead of `~/.android/debug.keystore` should it something like `C:/folderone/foldertwo/.android/debug.keystore`? As you can see I'm unsure of whether inverted commas are required or not, whether full paths are required or not! Is anyone able to provide a real world example?
