I am currently testing the roottools jar/library made by stericson in an app, but every time the app loads it force closes.
Here is the 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
}
}
}
And here is the logcat:

I am quite new to android, and I am now very confused :(
If someone could possibly help me, I would be grateful!
In Eclipse, right click your project, navigate to "Build Path", then to "configure build path" Now choose "add External Jar" Navigate to the RootTools .jar file you download and choose it. Navigate to "Order and Export" make sure the box is ticked next to the library, and move it to the top of the list. Finish up by choosing "ok"
I resolved this by separating the imports. Instead of:
import com.stericson.RootTools.*;
I only used/needed:
import com.stericson.RootTools.RootTools;
Try adding the others individually if you need them.
import com.stericson.RootTools.Mount;
import com.stericson.RootTools.Permissions;
import com.stericson.RootTools.RootToolsException;
import com.stericson.RootTools.Symlink;
import com.stericson.RootTools.SanityCheckRootTools;
It worked for me, hope it does for you!
