Hi @Shailesh K, and welcome to Android Forums

I've moved your question into the Application Development subforum so that fellow developers can assist you.

In the meantime, some additional information would be helpful. If you could share a snippet of the code you're having issues with that would be great.

You can wrap it in [code=java]...[/code] tags to preserve formatting and enable syntax highlighting.

Ok Thank you. Here is the code..

package com.example.safedrivingpro;

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

public class Last extends Activity {
    TextView tv1;
    TextView tv2;
    TextView tv3,tv4,tv5;
    [USER=1021285]@override[/USER]
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.last);
        TextView tv1= (TextView)findViewById([B]R.id.textView1[/B]); // ERROR LINE: R cannot be resolved..
        TextView tv2= (TextView)findViewById([B]R.id.textView2[/B]);// ERROR LINE: R cannot be resolved..
        TextView tv3= (TextView)findViewById([B]R.id.textView3[/B]);// ERROR LINE: R cannot be resolved..
        TextView tv4= (TextView)findViewById([B]R.id.textView4[/B]);// ERROR LINE: R cannot be resolved..
        Bundle b = getIntent().getExtras();
        int count=b.getInt("Color1");
        int speedcount=b.getInt("Color2");
        int rating=b.getInt("Color3");
        float maxx=b.getFloat("Color4");
        tv2.setText("Number of alerts generated :"+count);
        tv3.setText("Maximum speed limit exceeded "+speedcount+" times");
        tv4.setText("Driver rating "+rating+"/5");
        //tv5.setText("Max Z value "+maxx);
      
    }

}

I added the code tag for you to make it a bit prettier.

I'm afraid that's about all I can do, though, since I'm not a developer. Hopefully someone will be able to assist shortly.

If you already did Project > Clean, then look at all your xml code. That's where I would get this error and wouldn't be able to run the app. Even though Eclipse may say the xml is good, there may still be an error.
