Stericson's root tools library not working - makes force close?
<p>I am currently testing the roottools jar/library made by stericson in an app, but every time the app loads it force closes.</p>

<p>Here is the code:</p>

<pre><code>package com.liamwli.root;

import android.app.Activity;
import android.os.Bundle;

import android.widget.Toast;

import com.stericson.RootTools.*;

public class root_test extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (RootTools.isBusyboxAvailable()) {
            setContentView(R.layout.main);
        } else {
            RootTools.offerBusyBox(this);
        }

        if (RootTools.isRootAvailable()) {
            Toast liam = Toast.makeText(this, "Root Available",
                    Toast.LENGTH_SHORT);
            liam.show();
        } else {
            // do something else
        }

    }
}
</code></pre>

<p>And here is the logcat:</p>
