カメラからクリックした写真を別のアクティビティ画像ビューに表示しようとしていますが、画像をバンドルからビットマップに取得しています..このエラーが発生します。私のコードは

package com.example.iwm;

import java.io.File;

import java.text.SimpleDateFormat;


import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.os.Environment;
import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.widget.Toast;

public class MainActivity extends Activity {

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
//private static final int RESULT_OK = -1;
private static final int MEDIA_TYPE_IMAGE = 1;

public static Bundle s = null;
//public static String y ;
private Uri fileUri;
private static Intent intent;
private static Intent intent2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

      // create Intent to take a picture and return control to the calling application
     intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
    intent.putExtra(android.provider.MediaStore.ACTION_IMAGE_CAPTURE, fileUri); // set the image file name

    // start the image capture Intent
    startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
    //onActivityResult(CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE, int resultCode, intent)
}


private Uri getOutputMediaFileUri(int type) {
    // TODO Auto-generated method stub
      return Uri.fromFile(getOutputMediaFile(type));
}

/** Create a File for saving an image or video */
@SuppressLint("SimpleDateFormat")
private static File getOutputMediaFile(int type){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this.

    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES), "IWMP-Images");
    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            Log.d("IWMP-Images", "failed to create directory");
            return null;
        }
    }

    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new java.util.Date());
    File mediaFile;
    if (type == MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
        "IMG_"+ timeStamp + ".jpg");
    }  else {
        return null;
    }

    return mediaFile;
}

@TargetApi(Build.VERSION_CODES.HONEYCOMB_MR1)
@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            // Image captured and saved to fileUri specified in the Intent
           Toast.makeText(this, "Image saved to:\n" + fileUri, Toast.LENGTH_LONG).show();
            s =data.getExtras();

             intent2 = new Intent(MainActivity.this,MainActivity2.class);

             intent2.putExtra("Image", s);

            intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
            getApplicationContext().startActivity(intent2);



        } else if (resultCode == RESULT_CANCELED) {
            // User cancelled the image capture
        } else {
            // Image capture failed, advise user
             Toast.makeText(this, "Image NOT saved ", Toast.LENGTH_LONG).show();
        }
    }
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

  }

これから、データ（インテント）をバンドル S に保存し、それを activty2 に送信します

私の activity2 コードは

  package com.example.iwm;

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

  import android.view.Menu;
  import android.view.View;
  import android.widget.ImageView;
  import android.widget.TextView;

 public class MainActivity2 extends Activity {
 TextView tx;
 Bitmap bmp;
 ImageView ivUserImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_activity2);
    ivUserImage = (ImageView)findViewById(R.id.image);
    tx = (TextView)findViewById(R.id.text1);
    //tx.setText(MainActivity.y);
 Bundle bundle = getIntent().getExtras();
 try
 {
 bmp =(Bitmap)bundle.get("Image");

 }
 catch(Exception e)
 {
     tx.setText(e.toString());
}
 ivUserImage.setImageBitmap(bmp);
 //int  i=10;
}


public void upload(View view)
{

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main_activity2, menu);
    return true;
}

  }

bundle.get("data")代わりbundle.get("Image")に、2 番目のアクティビティでバンドルからビットマップを取得するために使用します。次のように試してください：

Bundle bundle = getIntent().getExtras();
 try
 {
      // getting error here.
   bmp = (Bitmap)bundle.get("data");   //<< use data instead of Image
   ivUserImage.setImageBitmap(bmp);
 }
 catch(Exception e)
 {
     tx.setText(e.toString());}
 }
