noclassdefFounderror map view google maps android

Hi,
If you are facing the  NoClassDefFound Error while using Maps, it means you are not using the Google Api. I mean to say is you need to use Google API in Target in place of Android x.x (version). And also dont forget to include maps.jar. And three modification in xml files.

1. you need to include the Map Key in the main.xml (layout file).
2. you need to add in application attribute in Manifest file.
3. finally you need to give uses-permission to access internet. So add the following line.

Android : startActivityForResult() Example

Hi,

Here is the code for startActivityForResult() method, I think it will help you to understand this method’s utility

to return the value from called Activity to calling activity.

Calling Activity

 package com.example.checkforresult;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

public class CheckStartActivityForResult extends Activity {
int requestCode;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
Log.d("CheckStartActivity","OnCreate");
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent(this,CalledActivity.class);
startActivityForResult(i, requestCode);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("CheckStartActivity","onActivityResult and resultCode = "+resultCode);
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==1){
Toast.makeText(this, "Pass", Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(this, "Fail", Toast.LENGTH_LONG).show();
}
}
}

Called Activity

package com.example.checkforresult;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class CalledActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
        Log.d("CalledActivity","OnCreate ");
       //String value = "rahul";
        Intent in = new Intent();
        setResult(1,in);//Here I am Setting the Requestcode 1, you can put according to your requirement
        finish();
}

And Please both services in your manifest file.
