How to start gallery app from an android app?

I am trying to open the gallery app from my android application. I want to just open the gallery app and not other apps with like fotos.
I have tried
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
and
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setType("image/*");
and
intent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
The problem is that all this show a dialog where I can pick again from all apps that have images. So it shows a dialog with "Gallery", "Fotos", etc....
Is there a possibility to open just one app, without having to chose again?

EDIT: If you want to use the gallery API, which does show photos from all photo apps on the phone and which is not a standalone user-accessible app itself, you could use this code:
private static final int PICK_IMAGE = 100;
private ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_picker);
imageView = (ImageView) findViewById(R.id.image_view);
Button pickImageButton = (Button) findViewById(R.id.pick_button);
pickImageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
openGallery();
}
});
}
private void openGallery() {
Intent gallery =
new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, PICK_IMAGE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
Uri imageUri = data.getData();
imageView.setImageURI(imageUri);
}
}
}
Unfortunately, I don't believe choosing photos from a specific app is possible, as "the gallery app" that comes installed on devices varies by manufacturer and OS skin. For example, the default gallery on Pixel devices is actually Google Photos.
If I misunderstood, and you do want to simply launch the Gallery app, you can include the following code in your /src/[ActivityName].java file:
package com.example.andy.myapplication;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
int view = R.layout.activity_main;
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(view);
final LinearLayout parent = findViewById(R.id.parent);
textView = findViewById(R.id.text);
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.sec.android.gallery3d");
if (launchIntent != null) {
startActivity(launchIntent);
} else {
Toast.makeText(MainActivity.this, "There is no package available in android", Toast.LENGTH_LONG).show();
}
}
});
}
}
Notice that the app being opened is Gallery, the default Samsung photo gallery app. If you want to replace this with Google Photos, you would replace com.sec.android.gallery3d with com.google.android.apps.photos.

Android Capture image with filename

this is my first day on android and i would like to make an app that will capture an image and the image name will output at the variable and textbox under the ImageView.
This is my code now and capture image is functioning. What i need to do next is to get the file name and filepath. Thanks. I tried to find but i dont know where to put the codes.
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class Create extends ActionBarActivity {
Button capImg;
int requestcode = 1;
ImageView imgView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create);
capImg = (Button)findViewById(R.id.capImg);
imgView = (ImageView)findViewById(R.id.imgView);
capImg.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0){
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(i.resolveActivity(getPackageManager())!=null){
startActivityForResult(i, requestcode);
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.create, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void onActivityResult(int requestCode, int resultcode, Intent data){
if(requestCode==requestcode){
if(resultcode==RESULT_OK){
Bundle bundle = new Bundle();
bundle = data.getExtras();
Bitmap BMP;
BMP = (Bitmap)bundle.get("data");
imgView.setImageBitmap(BMP);
}
}
}
}

To save a picture Add a fileUri to the intent.
private Uri fileUri;
fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO); // create a file to save the video
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
http://developer.android.com/guide/topics/media/camera.html
#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" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}

Android ImageView content disapearing after showing

My application does this: takes a photo, then show the photo in an ImageView. The weird thing is that the photo is displayed for about a second (after taking it with the camera), and then the ImageView is empty again.
This is my code:
publish.xml
<ImageView
android:id="#+id/itemImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
PublishActivity.java
package ar.com.guiagratis;
import java.io.File;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.drawable.BitmapDrawable;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;
public class PublishActivity extends Activity {
final int TAKE_PICTURE_REQUEST_CODE = 115;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.publish);
}
public void btnNextClick(View v) {
// TODO: disable all buttons
//Intent intent=new Intent(getApplicationContext(), TakePhotoActivity.class);
// startActivityForResult(intent, TAKE_PICTURE_RESULT_CODE);
Toast.makeText(getApplicationContext(), "Sacate una foto viteh", Toast.LENGTH_SHORT).show();
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photoFile = new File(Environment.getExternalStorageDirectory(), "Photo.png");
Uri imageUri = Uri.fromFile(photoFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, TAKE_PICTURE_REQUEST_CODE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case TAKE_PICTURE_REQUEST_CODE:
if (resultCode == Activity.RESULT_OK) {
File photoFile = new File(Environment.getExternalStorageDirectory(), "Photo.png");
Uri imageUri = Uri.fromFile(photoFile);
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
imageUri, Toast.LENGTH_LONG).show();
Bitmap myBitmap = BitmapFactory.decodeFile(imageUri.getPath());
BitmapDrawable ob = new BitmapDrawable(myBitmap);
ImageView myImage = (ImageView) findViewById(R.id.itemImage);
myImage.setBackgroundDrawable(ob);
Toast.makeText(getApplicationContext(), "Qué linda foto! ", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Hubo un problema al subir la imágen... ", Toast.LENGTH_SHORT).show();
}
}
}
}
Any help will be appreciated.

You're using setBackgroundDrawable(Drawable drawable) which sets the View's background.
If you want to change the ImageView's content you need to use
setImageDrawable(Drawable drawable)
or
setImageBitmap(Bitmap bm)

Ok, I finally found the problem. I was not aware that I need to use onSaveInstanceState and onRestoreInstanceState to store the values I don't want to loose from an Activity when I'm doing certain things, like initiating the Camera and taking a photo.
So I added this code:
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
// Save UI state changes to the savedInstanceState.
// This bundle will be passed to onCreate if the process is
// killed and restarted.
savedInstanceState.putBoolean("photoUploaded", photoUploaded);
}
#Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Restore UI state from the savedInstanceState.
// This bundle has also been passed to onCreate.
photoUploaded = savedInstanceState.getBoolean("photoUploaded");
if (photoUploaded) {
File photoFile = new File(Environment.getExternalStorageDirectory(), "Photo.png");
Uri imageUri = Uri.fromFile(photoFile);
Bitmap myBitmap = BitmapFactory.decodeFile(imageUri.getPath());
BitmapDrawable ob = new BitmapDrawable(myBitmap);
ImageView myImage = (ImageView) findViewById(R.id.uploadedImage);
myImage.setBackgroundDrawable(ob);
}
}
and now is working.
Not sure how to do to make this question as solved.

Android Camera activity stays open

I'm trying to take a picture with my Android app but when I take the image, the camera display doesn't go away. The code I am using is below. I also used the SDK on Google's developer website SDK.
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.Camera;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mainButton = (Button)findViewById(R.id.mainBtn);
mainButton.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Intent userCreationIntent = new Intent(v.getContext(), SecondviewActivity.class);
//startActivity(userCreationIntent);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
return false;
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ImageView imageView = (ImageView)findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
#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;
}
}

The problem is within your onTouchListener for the Button!
I just ran your code and changed the onTouchListener to a onClickListener for the Button instead and the code is working.
See my revised code here:
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mainButton = (Button) findViewById(R.id.mainBtn);
mainButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
}
}
}
I'm not precisely sure, why you're using the onTouchListener for a Button, but it's not working apparently - really weird behavior actually ;-)
EDIT: Just a small update. I tried to debug the code and if you use the onTouchListener instead of the onClickListener, when clicking on the button, you actually trigger 3 MotionEvents: MotionEvent.ACTION_DOWN, MotionEvent.ACTION_MOVE and MotionEvent.ACTION_UP.
Now the first event MotionEvent.ACTION_DOWN will trigger your intent to show the camera and when you click OK after you've taken a picture, the next MotionEvent MotionEvent.ACTION_MOVE is waiting in line to be triggered and this will send you to the camera activity once again. Now after taking one more picture and clicking OK, you return to your activity and now the last MotionEvent MotionEvent.ACTION_UP is waiting in line and triggers a 3rd call to the camera activity. After the last camera call, you will be able to get back to your activity without problems ;-)
Why the onClickListener doesn't do this, is because it handles a "full" click which could be MotionEvent.ACTION_DOWN, MotionEvent.ACTION_MOVE and MotionEvent.ACTION_UP and so all 3 events is happening in ONE click instead.
Hope this helps ;-)

This is happening because you are not attaching a path with the intent as to tell Android where to store the image. I had the same problem too.
Try the following code: ( I just added 4 lines )
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.Camera;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
// Creating the Uri where Camera saves a picture each time
String imagePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + System.currentTimeMillis() + "_myCameraImage.jpg";
File imageFile = new File(imagePath);
imageUri = Uri.fromFile(imageFile);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mainButton = (Button)findViewById(R.id.mainBtn);
mainButton.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Intent userCreationIntent = new Intent(v.getContext(), SecondviewActivity.class);
//startActivity(userCreationIntent);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
return false;
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ImageView imageView = (ImageView)findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
#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;
}
}
Before you copy and paste this code, make sure that you have necessary import statements in your code like import statements for File, Uri etc.
I strongly hope it will work now :)

Android Camera : Picture should not be stored locally but should be saved temporarily in the App

I am new to android and am trying to make an android app where the user can click an image and save it to a database . However i do not want the image to be stored locally in the gallery folder. Or everytime a picture is taken it saves itself in a self made directory on the phone and keeps replacing earlier pics .I donot want all pictures to be stored on the phone .
Below is my current code :
package com.example.camerastart;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class CameraMainActivity extends Activity
{
private static final int CAMERA_PIC_REQUEST = 2500;
private Button cam_button;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera_main);
cam_button = (Button) findViewById(R.id.button1);
cam_button.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
// TODO Auto-generated method stub
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK)
{
Bitmap image = (Bitmap) data.getExtras().get("data");
ImageView imageview = (ImageView) findViewById(R.id.imageView1);
imageview.setImageBitmap(image);
}
}
#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_camera_main, menu);
return true;
}
}
any help will be appreciated

You can make a folder, and save all the images to this folder.
just remember to add .nomedia file to this folder, and then the gallery will not show those files
