how to select only camera capture images from gallery?

I want to pick only those images from gallery which are clicked from camera,not present from other sources.
Cursor imagecursor = getApplicationContext().getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID}, null,
null, null);
This query gives me all the images.
I want the path to camera images irrespectice of gallery and camera intent.Is there some generic method which returns the path of captured images path

here is an example hope it help!!
package com.mahesh.gallerytestapp;
public class MainActivity extends Activity {
Uri selectedImageUri;
String selectedPath;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.bGallery);
Button bCam= (Button) findViewById(R.id.bCamera);
ImageView preview = findViewById(R.id.preview);
bCam.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 100);
}
});
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
openGallery(10);
}
});
}
public void openGallery(int req_code){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select file to upload "), req_code);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if(data.getData() != null){
selectedImageUri = data.getData();
}else{
Log.d("selectedPath1 : ","Came here its null !");
Toast.makeText(getApplicationContext(), "failed to get Image!", 500).show();
}
if (requestCode == 100 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
selectedPath = getPath(selectedImageUri);
preview.setImageURI(selectedImageUri);
Log.d("selectedPath1 : " ,selectedPath);
}
if (requestCode == 10)
{
selectedPath = getPath(selectedImageUri);
preview.setImageURI(selectedImageUri);
Log.d("selectedPath1 : " ,selectedPath);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}

Application crashes when I choose a picture from gallery and integrate it into Gmail

I'm trying to create an application that lets the user choose an image from the gallery or take a new one, and then send it via email. The function that takes the picture works perfectly (I can take it and then email it). But when I try to choose a picture, my application crashes. Here is my Java file:
public class Request extends Activity {
Button send;
Bitmap thumbnail;
File pic;
protected static final int CAMERA_PIC_REQUEST = 0;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.requestscreen);
send=(Button) findViewById(R.id.sendBtn);
Button camera = (Button) findViewById(R.id.camBtn);
camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
Button galbtn = (Button) findViewById(R.id.galBtn);
galbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
send.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, new String[]{"test#test.com"});
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
//Log.d("URI#!##!#!###!", Uri.fromFile(pic).toString() + " " + pic.exists());
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic));
i.setType("image/png");
startActivity(Intent.createChooser(i,"Share you on the jobing"));
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(thumbnail);
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
pic = new File(root, "pic.png");
FileOutputStream out = new FileOutputStream(pic);
thumbnail.compress(CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
Log.e("BROKEN", "Could not write file " + e.getMessage());
}
}
if (requestCode == SELECT_PICTURE){
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
TextView uritv = null;
uritv.setText(selectedImagePath.toString());
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
I don't know what I need to change in my code, can anyone help me?

Seems clear to me
TextView uritv = null;
uritv.setText(selectedImagePath.toString());
In other words, you're trying to use a method on a null object.
My guess is you're not instancing the real TextView which would be something like
TextView uritv = (TextView) findViewById(R.id.uritv);
which, of course, depends on the real nomenclature of your textview

Android : Gallery

I am working on app for editing photos.
I have a button in first activity and ImageView in second activity. When I click the button it would open gallery and I would be able to select an image. The selected image needs to appear in my ImageView in second activity but it doesn't. For time being i am displaying image in first activity it self but can anyone suggest me how to display that image in next activity.
Below is my code.
public class Camera_Gallery_Option extends Activity {
private static final int CAMERA_REQUEST = 1888;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera_gallery_option);
Button galleryButton= (Button) findViewById(R.id.button1);
galleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
SELECT_PICTURE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
imageview.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

Pass the selectedImageUri to the second activity and set the uri to image view in the second activity ?
startActivity(new Intent(this, SecondActivity.class).setData(selectedImageUri));
In the SecondActivity:
protected void onCreate(Bundle savedInstanceState) {
...
imageView.setImageURI(getIntent().getData());
}

Android photo browse upload Error : Failure Delivering Result resultinfo{who=null......}

Whenever I try to click on the browse button , I want to browse my gallery and select a photo from it and display it in a new activity.
Until I displayed the photo on the same activity there was no error , but as soon I change the code to transfer the photo on another intent there is a force close error
Here is my code:
Main screen :
Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0)
{
Intent intent1 = new Intent(MainActivity.this,Edit.class);
startActivity(intent1);
}
});
Another screen :
public class Edit extends Activity
{
private String selectedImagePath;
private static final int SELECT_PICTURE = 1;
private ImageView img;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.edit);
img = (ImageView)findViewById(R.id.ImageView1);
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
if (requestCode == SELECT_PICTURE)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

How do I change the image in ImageView more than once?

My application adds a photo from your gallery to an ImageView just fine, but if I try and change the image (after one has already been selected) my app force closes. Is there a way to achieve this?
here is my code..
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
private ImageView img;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView)findViewById(R.id.myimageview);
((Button) findViewById(R.id.taptoadd))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}

Set the image through code .
ImageView imageView = (ImageView) findViewById(R.id.myimageview);
imageView.setImageResource(R.drawable.myimage);
