**For an Android application**
This code is used to get the hash key in your Android application for Facebook integration. I have tested all devices and it's working. Only change the package name of this code:
private void facebookHashKey() {
try {
PackageInfo info = getPackageManager().getPackageInfo("com.app.helpcove", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String hashCode = Base64.encodeToString(md.digest(), Base64.DEFAULT);
System.out.println("Print the hashKey for Facebook :"+hashCode);
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
}
You can use this code in any activity. It will log the hashkey in the logcat, which is the debug key. This is easy, and it's a relief than using SSL.
PackageInfo info;
try {
info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md;
md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String something = new String(Base64.encode(md.digest(), 0));
//String something = new String(Base64.encodeBytes(md.digest()));
Log.e("hash key", something);
}
} catch (NameNotFoundException e1) {
Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
Log.e("exception", e.toString());
}
You can delete the code after knowing the key ;)
