private final String TAG = "BlobsActivity";
private String mContainerName;
private ImageView mImgBlobImage;
private Uri mImageUri;
private AlertDialog mAlertDialog;

Button btnSelect, btnR;
ImageView iv;
TextView tv1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //Get access to the storage service
    StorageApplication myApp = (StorageApplication) getApplication();
    mStorageService = myApp.getStorageService();
    //Get data from the intent that launched this activity
    Intent launchIntent = getIntent();
    mContainerName = launchIntent.getStringExtra("ContainerName");

    //Get the blobs for the selected container
    mStorageService.getBlobsForContainer(mContainerName);       


        setContentView(R.layout.camera);
        tv1=(TextView) findViewById(R.id.editText1);            
        btnR = (Button)findViewById(R.id.btnReport);
        iv = (ImageView) findViewById(R.id.imageView1); 
        btnSelect = (Button)findViewById(R.id.btnSelect);
        //Set select image handler
        btnSelect.setOnClickListener(new OnClickListener() {                
            @Override
            public void onClick(View v) {
                selectImage();
            }
        });

}

    public void onClick(View v) {
    mStorageService.getSasForNewBlob(mContainerName, tv1.getText().toString());

        }

@Override

    super.onActivityResult(requestCode, resultCode, data);
    try {
        //handle result from gallary select
        if (requestCode == 1111) {
            Uri currImageURI = data.getData();
            mImageUri = currImageURI;
            //Set the image view's image by using imageUri
            mImgBlobImage.setImageURI(currImageURI);
        }

Here is my StorageApplication Class

package com.example.testproject;

import android.app.Application;


public class StorageApplication extends Application {

private StorageService mStorageService;

public StorageApplication() {}

public StorageService getStorageService() {
    if (mStorageService == null) {
        mStorageService = new StorageService(this);
    }
    return mStorageService;
}

}
