I have seen several examples where people access .xml files like below from java.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">YYYYYYYYY</string>
<string name="app_id">999999999999</string>
<string name="leaderboard_id">XXXXXXXXXXX</string>
</resources>
I have seen usage of android.R package claimed to be succesfull at fetching the strings within LibGDX setups. However, I keep running into error: cannot find symbol variable leaderboard_id
, leaderbord_id is the only variable I currently trying.
I have tried cleaning up my project without errors but once building again I get the above error for every time I try to access it.
My strings.xml
resides in ../android/res/values/
and I am trying to access it like getString(R.string.leaderboard_id)
without success. Furthermore I tried Sync project with gradle
and different API's and builds.
I am using the official Google BaseGameUtils which gives a bootstrap warning about classpath not being set
but I don't see any issues with that. I'm at a point starting to doubt if this is possible or changed since the posts about this I found are old.
Here is my complete code:
AndroidLauncher.java
package net.madmenyo.multiplayertest.android;

import net.madmenyo.multiplayertest.IGoogleServices;
import net.madmenyo.multiplayertest.MultiplayerTest;
public class AndroidLauncher extends AndroidApplication implements IGoogleServices {
private GameHelper _gameHelper;
private final static int REQUEST_CODE_UNUSED = 9002;
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create game helper
_gameHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);
_gameHelper.enableDebugLog(false);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
initialize(new MultiplayerTest(this), config);
}
@Override
protected void onStart()
{
super.onStart();
_gameHelper.onStart(this);
}
@Override

{
super.onStop();
_gameHelper.onStop();
}
@Override

{
super.onActivityResult(requestCode, resultCode, data);
_gameHelper.onActivityResult(requestCode, resultCode, data);
}
@Override
public void signIn() {
try {
runOnUiThread(new Runnable() {
@Override
public void run() {
_gameHelper.beginUserInitiatedSignIn();
}
});
}
catch (Exception e)
{
Gdx.app.log("MainActivity", "Log in failed: " + e.getMessage());
}
}
@Override
public void signOut() {
try
{
runOnUiThread(new Runnable() {
@Override

_gameHelper.signOut();
}
});
}
catch (Exception e)
{
Gdx.app.log("MainActivity", "Log out failed: " + e.getMessage());
}
}
@Override
public void submitScore(long score) {
if (isSignedIn() == true)
{
Games.Leaderboards.submitScore(_gameHelper.getApiClient(), getString(R.string.leaderboard_id), score); //Error cannot find symbol variable leaderboard_id
getApplicationContext().getResources().getString(R.string.leaderboard_id); //Error

}
@Override
public boolean isSignedIn() {
return _gameHelper.isSignedIn();
}
}
Looks like you've imported wrong R
class.
import android.R;
You need the R
file pointing to your own resources, not the resources defined within Android SDK. What you need is (assuming that your application's package called net.madmenyo.multiplayertest.android
):
import net.madmenyo.multiplayertest.android.R;
