How much size of file can be pass by Intent in Android?

I have problem with intent in android. I use intent transfer image have been made by camera (camera of device) to bitmap, and then I show it. But it's too small. My camera is 8mpx.
so why and how can I fix it?

Could you be more specific, Is the photo taken directly from camera or selected from gallery?
Most probably the size of the imageView itself is small. A photo no matter how small can be enlarged to fit a large imageView but it will pixelate.
If you have its URI you could try this code to convert data from intent to uri which then gets converted to bitmap and then assigned to your imageView
Uri imageUri = intent.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),imageUri);
Imageview imgview1 = (Imageview ) findViewById (R.id.imgview1);
imgeview1.setImageBitmap(bitmap);
You could use the above code to convert URI recieved from camera to a bitmap and assign it to the imageView.
If the image still looks small then check the size of the imageView.

private static final int TAKE_PICTURE = 1;
private Uri imageUri;
public void takePhoto(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
}

How to show Picture into a activity after taken and saved from custom camera

In My app I am taking picture and I am successfully saving it in the gallery after compressing it. Now I want to show it into other activity, so that user can share it or view it at least. So How can I do that.
Following is my code which is saving picture and just after saving it, it shows ad , and on the adClosed event I want to send that taken picture to other activity , How Can I do that. My code just goes like this ..
File storagePath = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator + "MyAnimals");
storagePath.mkdirs();
String finalName = Long.toString(System.currentTimeMillis());
//this snippet is saving image And I am showing ad after saving picture
File myImage = new File(storagePath, finalName + ".jpg");
String photoPath = Environment.getExternalStorageDirectory().getAbsolutePath() +"/" + finalName + ".jpg";
try {
FileOutputStream fos = new FileOutputStream(myImage);
newImage.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
//refreshing gallery
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(Uri.fromFile(myImage));
sendBroadcast(mediaScanIntent);
} catch (IOException e) {
Toast.makeText(this, "Pic not saved", Toast.LENGTH_SHORT).show();
return;
}
Toast.makeText(this, "Pic saved in: " + photoPath, Toast.LENGTH_SHORT).show();
displayInterstitial();
interstitial.setAdListener(new AdListener() {
#Override
public void onAdClosed() {
Log.v("Add time");
Intent intent = new Intent(CameraActivity.this,ShowCapturedImage.class);
//Now How to send the saved picture to the image view of other activity?
startActivity(intent);
super.onAdClosed();
}
});

1) put taken image path in intent
2) get path in other activity and set it in imageview
public static final int REQUEST_CODE_FROM_CAMERA = 112;
private Uri fileUri;
String image_path = "";
//Catch image from below function
private void fromCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
Log.d("FROM CAMERA CLICKED file uri", fileUri.getPath());
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, REQUEST_CODE_FROM_CAMERA);
}
//On Activity result store image path
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_FROM_CAMERA
&& resultCode == Activity.RESULT_OK) {
try {
image_path = fileUri.getPath();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
}
On Click of any button
Intent iSecond=new Intent(FirstActivity.this,SecondActivity.class);
iSecond.putExtra("image_path",image_path);
startActivity(iSecond);
In Second Activity onCreate()
Bundle extras = intent.getExtras();
if(extras != null)
String image_path = extras.getString("image_path");
From this image path , You can get image and set to imageview
ImageView iv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
iv = (ImageView) findViewById(R.id.imageView1);
File imgFile = new File("/storage/emulated/0/1426484497.png");
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile
.getAbsolutePath());
iv.setImageBitmap(myBitmap);
}
}

You can do this by adding a ImageView to your Activity.
A simple ImageView should look like this:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView" />
Then you capture it in your Activity class
ImageView imageView = (ImageView) this.findViewById(R.id.imageView);
Now the fun part. We'll capture your image using the image URI and parse it in a bitmap.
Bitmap bitmap = BitmapFactory.decodeFile(fileUri.getPath()); //Here goes your image path
imageView.setImageBitmap(Bitmap.createScaledBitmap(bitmap,imageView.getWidth(), imageView.getHeight(), false)); //I scale the bitmap so it show properly. If the image is too big, it wont show on the ImageView
That should do the trick, tell me if it works!

android Camera picture not being displayed

the following is my camera code
public void takepic(View view) {
Spinner spinner1 = (Spinner)findViewById(R.id.spinner1);
String schname = spinner1.getSelectedItem().toString();
String[] tokens = schname.split(" ");
String timeStamp = new SimpleDateFormat("dd-MM-yyyy-HH-mm-ss").format(new Date());
String imageFileName = tokens[0] + "-" + timeStamp + ".jpg";
TextView detail = (TextView)findViewById(R.id.textView1);
detail.setText(imageFileName);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
String name = imageFileName;
File file = new File(path, name );
ImageView mImage = (ImageView) findViewById(R.id.mImageView);
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
new SingleMediaScanner(this, file);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
mImage.setImageBitmap(thumbnail);
}}}
when invoked it runs the camera app takes a photo and stores it in the Pictures folder with a pre defined filename
problem is it should then display the image in an imageview call mImageView but it doesnt
mImageView already has a bitmap in it. it should change to the new image but instead stays as it s
ouputFileURI reports the correct path and filename but I cant get it to work
Any ideas?
Mark

Since you are explicitly giving the file name where to store the image, you should read the Bitmap from that file rather than loading it from the Intent. It sounds like data.getExtras().get("data"); is returning null.

saving camera pics in sd card

I am using the following code to take picture, using the device camera. I am new to android. Can anybody please help me and tell me where I should specify the path. I want to save images in a separate folder in sd card. Any help is deeply appreciated.
private static final int CAMERA_PIC_REQUEST = 2500;
bcontinue.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == CAMERA_PIC_REQUEST && resultCode==RESULT_OK)
{
try{
Byte image1 = (Byte) data.getExtras().get("data");
FileOutputStream fos = openFileOutput("filename.bmp", Context.MODE_PRIVATE);
fos.write(image1);
fos.close();
}
catch(Exception e){
}
Bitmap image = (Bitmap) data.getExtras().get("data");
ImageView imageview = (ImageView) findViewById(R.id.imageView1);
imageview.setImageBitmap(image);
Context context = getApplicationContext();
CharSequence text = "Click on the image!";
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}

The below code will start the default camera and have the camera save the image to the specified uri. The key is to put the extra "MediaStore.EXTRA_OUTPUT" along with the desired uri.
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/Images/" + image_name + ".jpg");
Uri imageUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, 0);

Android save camera's photo into internal memory

super.onActivityResult(requestCode, resultCode, data);
if (resultCode == CAMERA_PIC_REQUEST) {
}
I opened camera activity. How to get the picture name & save it to particular location?
please help me on this.
thank you in advance.

I'm calling camera
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
and saving to sd card like this
final ImageView img = new ImageView(this);
img.setLayoutParams(new LayoutParams(100, 100));
image2 = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(image2);
String incident_ID = IncidentFormActivity.incident_id;
//l2.addView(img);
imagepath="/sdcard/RDMS/"+incident_ID+ x + ".png";
File file = new File(imagepath);
try {
bm = Bitmap.createScaledBitmap( image2,400, 300, true);
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bm.compress(CompressFormat.PNG, 90, ostream);
ostream.close();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"yourfirst error message is "
+ e.toString(), 1000).show();
}

You may need to change the line
if (resultCode == CAMERA_PIC_REQUEST) {
to
if (requestCode == CAMERA_PIC_REQUEST) {

You are already saving the picture. You provided the location in MediaStore.EXTRA_OUTPUT.

Doing a DB you will have to have a look at this link is a little bit to much to explain
