Hai am new in Android Application.i Generated a code to take picture by using Camera.Now i want to view the Taken Pictures without using Database.i dont know how to do this.AnyBody please help me.
Thanks in advance
Here my Code
private void createCamera() {
// TODO Auto-generated method stub
preview = new Preview(this);
((FrameLayout) findViewById(R.id.preview)).addView(preview);
buttonClick = (Button) findViewById(R.id.buttonClick);
buttonClick.setOnClickListener( new OnClickListener() {
public void onClick(View v) {
preview.camera.takePicture(shutterCallback, rawCallback, jpegCallback);
}
});
Log.d(TAG, "onCreate'd");
}
ShutterCallback shutterCallback = new ShutterCallback() {
public void onShutter() {
Log.d(TAG, "onShutter'd");
}
};
/** Handles data for raw picture */
PictureCallback rawCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
Log.d(TAG, "onPictureTaken - raw");
}
};
/** Handles data for jpeg picture */
PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
FileOutputStream outStream = null;
try {
outStream = new FileOutputStream(String.format("/sdcard/%d.jpg", System.currentTimeMillis()));
outStream.write(data);
outStream.close();
Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {}
Log.d(TAG, "onPictureTaken - jpeg");
}
};
private void createpictures() {
img = (ImageView)findViewById(R.id.ImageView01);
((Button) findViewById(R.id.Button01)).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);
}
Simple as this:
Intent in = new Intent(Intent.ACTION_VIEW, Uri.parse("file://"+yourFileName));
startActivity(in);
Default app for viewing pictures will start, or if there's no default, user get selection dialog which app to use.
you really dont need to use database to view taken picture.
To get new image - open an intent for Camera. like this
To see all other captured images, open Gallery. see this discussion
heres a good overview of opening data via intents on your phone. All this documentation is in here as well http://developer.android.com/guide/topics/intents/intents-filters.html but not as clear to follow.
http://indyvision.net/2010/03/android-using-intents-open-files/
File imageFile2View = new File("/sdcard/nice_photo.jpeg");
Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(imageFile2View), "image/jpeg");
startActivity(i);
Now if what your looking for is to display the picture you took in your own activity you can use.
String file = String.format("/sdcard/%d.jpg", System.currentTimeMillis());
//SAVE IMAGE TO file
img.setImageURI(URI.parse(file));
or
String file = String.format("/sdcard/%d.jpg", System.currentTimeMillis());
//SAVE IMAGE TO file
bitmap = BitmapFactory.decodeFile(file);
img.setImageBitmap(bitmap);

Despite getting the necessary access to the file in Android, when I select a photo from the gallery in Android 11 and above, Android shows the message access denied.
I just select the image and receive it as a bitmap.
I try thease
1
...
Manifest permissions:
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="32" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="29" />
Select image from gallery:
public void selectImageFromGallery(ImageView view) {
setResourceImg(view);
checkListener();
if (tempFileFromSource == null) {
try {
tempFileFromSource = File.createTempFile("choose", "png", mContext.getExternalCacheDir());
tempUriFromSource = Uri.fromFile(tempFileFromSource);
} catch (IOException e) {
e.printStackTrace();
}
}
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.putExtra(MediaStore.EXTRA_OUTPUT, tempUriFromSource);
if (fragment == null) {
mContext.startActivityForResult(intent, REQUEST_PICTURE_FROM_GALLERY);
} else {
fragment.startActivityForResult(intent, REQUEST_PICTURE_FROM_GALLERY);
}
}
On Activity Result:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if ((requestCode == REQUEST_PICTURE_FROM_GALLERY) && (resultCode == Activity.RESULT_OK)) {
Log.d(TAG, "Image selected from gallery");
imageActionListener.onImageSelectedFromGallery(data.getData(), tempFileFromSource);
} else if ((requestCode == REQUEST_PICTURE_FROM_CAMERA) && (resultCode == Activity.RESULT_OK)) {
Log.d(TAG, "Image selected from camera");
imageActionListener.onImageTakenFromCamera(tempUriFromSource, tempFileFromSource);
} else if ((requestCode == REQUEST_CROP_PICTURE) && (resultCode == Activity.RESULT_OK)) {
Toast.makeText(mContext, "uryyg: "+data.toString(), Toast.LENGTH_SHORT).show();
Log.d(TAG, "Image returned from crop");
imageActionListener.onImageCropped(tempUriFromCrop, tempFileFromCrop);
}
}
Crop selected image:
public void requestCropImage(Uri uri, int outputX, int outputY, int aspectX, int aspectY) {
checkListener();
if (tempFileFromCrop == null) {
try {
tempFileFromCrop = File.createTempFile("crop", "png", mContext.getExternalCacheDir());
tempUriFromCrop = Uri.fromFile(tempFileFromCrop);
} catch (IOException e) {
e.printStackTrace();
}
}
// open crop intent when user selects image
final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
intent.putExtra("output", tempUriFromCrop);
intent.putExtra("outputX", outputX);
intent.putExtra("outputY", outputY);
intent.putExtra("aspectX", aspectX);
intent.putExtra("aspectY", aspectY);
intent.putExtra("scale", true);
intent.putExtra("noFaceDetection", true);
if (fragment == null) {
mContext.startActivityForResult(intent, REQUEST_CROP_PICTURE);
} else {
fragment.startActivityForResult(intent, REQUEST_CROP_PICTURE);
}
//Toast.makeText(mContext, "uri3: "+uri.toString(), Toast.LENGTH_SHORT).show();
}
And we return the uri of the cropped image in the cache to this method:
#Override
public void onImageCropped(Uri uri, File imageFile) {
try {
Uri selectedImage = uri;
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContext().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
// getting bitmap from uri
//Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
} catch (Exception e) {
e.printStackTrace();
}
}
You will need to use intent with an action set to Intent.ACTION_GET_CONTENT and set the type of this intent to match all the image files i.e. "image/*". If you want that user will able to select only specific image file formats like png or jpeg then use something like "image/png" or "image/jpeg".
The code below describes a fully working example that is tested on Android 12L.
Create intent like this
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
pickerActivityResultLauncher.launch(Intent.createChooser(intent, "Select a photo"));
Using the AndroidX activity result register
private ActivityResultLauncher<Intent> pickerActivityResultLauncher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result -> {
if(result.getResultCode() == RESULT_OK) {
// This is the URI for the selected photo from the user.
Uri photoUri = result.getData().getData();
// Set URI to the image view to display the image.
imageView.setImageURI(photoUri);
} else {
// Handle the no-image selection case.
}
});
If you want to use the old method (which has no guarantee that it works on every device) then you can use
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select a photo"), REQUEST_PICTURE_FROM_GALLERY)
The following code is able to save images in pictures directory, but I'm not able to find the perfect way to save image files to the desired app directory using URI.
Edit: The perfect way to store image files to a new directory which can be accessed by other apps is the requirement
SaveActivity.java
final MediaManager mediaManager = new MediaManager(this);
Uri imageURI = mediaManager.GetImageUri();
final ImageView imageHolder = findViewById(R.id.imageHolder);
Glide.with(this).load(imageURI).into(imageHolder);
final String filename = mediaManager.getFileName(imageURI);
save.setOnClickListener(new View.OnClickListener() {#Override public void onClick(View v) {
imageHolder.setDrawingCacheEnabled(true);
Bitmap bitmap = imageHolder.getDrawingCache();
MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, filename, "description");
}
});
MainActivity.java
ImageButton btImgSettings = findViewById(R.id.btnPhoto);
btnPhoto.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, 1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
switch (requestCode){
case 1: if (uri != null) {
String stringUri = uri.toString();
Intent intent = new Intent(this, SaveActivity.class);
intent.putExtra("imageId", stringUri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);
break;
default:
break;
}
}
}
MediaManager
public class MediaManager {
Activity activity;
public MediaManager(Activity activity) {
this.activity = activity;
}
public Uri GetImageUri() {
Uri imageURI = null;
Bundle bundle = activity.getIntent().getExtras();
if (bundle != null) {
String imageId = bundle.getString("imageId");
imageURI = Uri.parse(imageId);
}
return imageURI;
}
}
Thank you :)
Copy the file to your directory and then use.
Bitmap image= MediaStore.Images.Media.getBitmap(getContentResolver(), data.getData());
File root = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "YourDirectory");
if (!root.exists()) root.mkdirs();
String file = root.toString() + File.separator + "FileName" + ".jpg";
try {
FileOutputStream fOutputStream = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fOutputStream);
image.compress(Bitmap.CompressFormat.JPEG, 100, bos);
fOutputStream.flush();
fOutputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(context, new String[]{file}, null, null);
//This line notifies the system that an image was added and to show it in the gallery.
Hope this helps. Feel free to ask for any clarifications.
My first question would be, Is onCreate method needed on every new class in android ?
Next, can we use multiple onActivityResult method without causing distortion
?
For exemple my MainActivity and ShareActivity class both have their own onActivityResult and Oncreate method (code taken from git)
MainActivity is for opening camera and gallery
ShareActivity is for sharing images captured
Note : Both class check for permission first
I wanna call the ShareActivity in my MainActivity, the logical thing to do would be
share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(MainActivity.this, ShareActivity.class);
startActivity(myIntent);
}
});
But my ShareActivity also has this
#OnClick(R.id.open_share)
void onShareTouched() {
boolean has_perms = EasyPermissions.hasPermissions(ShareActivity.this, perms);
if (has_perms) {
shareImageFromBitmap(this.bmp);
} else {
EasyPermissions.requestPermissions(
ShareActivity.this,
getString(R.string.rationale_storage),
SHARE_STORAGE_PERMS_REQUEST_CODE,
perms);
}
}
And then I thought about calling it like this
ShareActivity.getInstance().onShareTouched();
But the app keep crashing, everytime I call the Share class,
Edit : Should I use implement ?
Note :the Share class works fine without MainActivity (I tried in new project)
for better understanding I leave the complete code below
ShareActivity
public class ShareActivity extends AppCompatActivity {
private static ShareActivity instance;
private static final String TAG = "ShareActivity";
private final int SHARE_STORAGE_PERMS_REQUEST_CODE = 900;
private final int RESULT_LOAD_IMG_REQUEST_CODE = 778;
private final String[] perms = { android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE};
private static final String IMAGE_URL = null;
private Bitmap bmp;
#BindView(R.id.open_share)
SimpleDraweeView imageView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
bmp = getBitmapFromUrl(IMAGE_URL);
imageView2.setImageURI(Uri.parse(IMAGE_URL));
instance = this;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RESULT_LOAD_IMG_REQUEST_CODE && resultCode == RESULT_OK) {
List<Image> images = ImagePicker.getImages(data);
if(images.size() > 0) {
String imagePath = images.get(0).getPath();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
bmp = BitmapFactory.decodeFile(imagePath, options);
imageView2.setImageURI(Uri.fromFile(new File(imagePath)));
}
}
}
#OnClick(R.id.open_share)
void onShareTouched() {
boolean has_perms = EasyPermissions.hasPermissions(ShareActivity.this, perms);
if (has_perms) {
shareImageFromBitmap(this.bmp);
} else {
EasyPermissions.requestPermissions(
ShareActivity.this,
getString(R.string.rationale_storage),
SHARE_STORAGE_PERMS_REQUEST_CODE,
perms);
}
}
#AfterPermissionGranted(SHARE_STORAGE_PERMS_REQUEST_CODE)
private void shareImageFromBitmap(Bitmap bmp) {
Uri uri = getUriImageFromBitmap(bmp, ShareActivity.this);
if(uri == null) {
//Show no URI message
return;
}
final Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, IMAGE_URL);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/png");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Share image using"));
}
private Bitmap getBitmapFromUrl(String url) {
Uri uri = Uri.parse(url);
ImageRequest downloadRequest = ImageRequest.fromUri(uri);
CacheKey cacheKey = DefaultCacheKeyFactory.getInstance().getEncodedCacheKey(downloadRequest, ShareActivity.this);
if (ImagePipelineFactory.getInstance().getMainFileCache().hasKey(cacheKey)) {
BinaryResource resource = ImagePipelineFactory.getInstance().getMainFileCache().getResource(cacheKey);
byte[] data = null;
try {
data = resource.read();
} catch (IOException e) {
e.printStackTrace();
}
return BitmapFactory.decodeByteArray(data, 0, data.length);
}
return null;
}
private Uri getUriImageFromBitmap(Bitmap bmp, Context context) {
if(bmp == null)
return null;
Uri bmpUri = null;
try {
File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "IMG_" + System.currentTimeMillis() + ".png");
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
bmpUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
public static ShareActivity getInstance() {
return instance;
}
}
MainActivity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
if (requestCode == OPEN_THING) {
Uri uri = Objects.requireNonNull(data.getExtras()).getParcelable(ScanConstants.SCANNED_RESULT);
Bitmap bitmap;
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
if (uri != null) {
getContentResolver().delete(uri, null, null);
}
scannedImageView.setImageBitmap(bitmap);
FileOutputStream outputStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File directory = new File(sdCard.getAbsolutePath() + "/Scan Documents");
directory.mkdir();
String filename = String.format("d.jpg", System.currentTimeMillis());
File outFile = new File(directory, filename);
Toast.makeText(this, "Image Saved Successfully", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(outFile));
sendBroadcast(intent);
try {
outputStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.flush();
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
I found a better easier way
I had to completely change my method, I put everything in my button onClick
share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Drawable myDrawable = scannedImageView.getDrawable();
Bitmap bitmap = ((BitmapDrawable)myDrawable).getBitmap();
try{
File file = new File(MainActivity.this.getExternalCacheDir(), "myImage.png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 80, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(Intent.createChooser(intent, "Share Image Via"));
}catch (FileNotFoundException e){
e.printStackTrace();
Toast.makeText(MainActivity.this, "File not found", Toast.LENGTH_SHORT).show();
}catch (IOException e){
e.printStackTrace();
}catch (Exception e){
e.printStackTrace();
}
}
});
No need ShareActivity it works great
Ok guys, so after spending one day trying to figure out how to upload an image to parse servers i finally decided to ask for your help. I didn't find any full example on how to do this.
What i want to be able to do is:
select image from gallery (already did that)
load into inageView (already did that)
at onClick event upload the selected picture to Parse servers (my problem)
Here you have my code snippet so far, but it's not working.
private static int RESULT_LOAD_IMAGE = 1;
mSubmitJobBTN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
createJob(); //this method will send data to Parse
}
});

String mJobDescriptionText, String mJobPriceText) {
/*Bitmap bitmap = BitmapFactory.decodeFile("picturePath");
// Convert it to byte
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Compress image to lower quality scale 1 - 100
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] image = stream.toByteArray();
try {
image = readInFile(path);
} catch (Exception e) {
e.printStackTrace();
}*/
ParseUser user = ParseUser.getCurrentUser();
anunt.put("username", "andrei");
anunt.put("jobName", mJobNameText);
anunt.put("jobDescription", mJobDescriptionText);
anunt.put("jobPrice", mJobPriceText);
/*// Create a column named "jobPicture" and set the string

You should use PHP or any server script to upload image from android to the server. Try the URL given below,
Upload Image to Server PHP Android
this is the answer!
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Compress image to lower quality scale 1 - 100
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] imagez = stream.toByteArray();
ParseFile filez = new ParseFile("androidbegin.png",
imagez);
filez.saveInBackground();
imgupload = new ParseObject("Anunturi");
imgupload.put("JobPictureName", "AndroidBegin Logo");
imgupload.put("jobPicture", filez);
imgupload.put("jobPictureName", picturePath);
imgupload.put("username", mUsernameText);
imgupload.put("jobName", mJobNameText);
imgupload.put("jobDescription", mJobDescriptionText);
imgupload.put("jobPrice", mJobPriceText);
imgupload.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
if (e == null) {
Toast.makeText(getApplicationContext(),
"Job succesfully posted!",
Toast.LENGTH_LONG).show();
Intent in = new Intent(
getApplicationContext(),
JobsListActivity.class);
in.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(in);
finish();
} else {
mGoogleNow
.setVisibility(mGoogleNow.INVISIBLE);
Toast.makeText(getApplicationContext(),
"An error occured",
Toast.LENGTH_LONG).show();
}
}
});
} else {
bitmap = null;
imgupload = new ParseObject("Anunturi");
imgupload.put("username", mUsernameText);
imgupload.put("jobName", mJobNameText);
imgupload.put("jobDescription", mJobDescriptionText);
imgupload.put("jobPrice", mJobPriceText);
imgupload.put("jobPictureName", "null");
imgupload.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
if (e == null) {
Toast.makeText(
getApplicationContext(),
"Job succesfully posted!",
Toast.LENGTH_LONG).show();
Intent in = new Intent(
getApplicationContext(),

I'm taking pictures through the following code and saving to SD card, but the pictures that it produces are such low quality and really bitty even with 100% quality. Maybe bitmap.compress isn't the right way to go (or bitmap at all?!)
Heres my code:
public class TakePhoto extends Activity {
ImageView iv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_take_photo);
iv = (ImageView) findViewById(R.id.imageView1);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Bitmap bm = (Bitmap) data.getExtras().get("data");
Random generator = new Random();
String randFileName = String.valueOf (generator.nextInt(965) + 32);
String both = "/mnt/extSdCard/DirectEnquiries/"+ randFileName + ".jpg";
File imageFile = new File(both);
writeBitmapToMemory(imageFile, bm);
iv.setImageBitmap(bm);
}
public void writeBitmapToMemory(File file, Bitmap bitmap) {
FileOutputStream fos;
try {
Log.e("Tom", "Starting take stream");
fos = new FileOutputStream(file);
Log.e("Tom", "Got stream");
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
Log.e("Tom", "Saved Image");
fos.close();
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
Please call the below function to capture image from camera.
private final static String FOLDER_NAME = "YourAppName/Image/";
private Uri selectedImageUri = null;
public void startCamera()
{
File photo = null;
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
{
photo = new File(android.os.Environment.getExternalStorageDirectory(), FOLDER_NAME+File.separator+timeStamp+".png");
}
else
{
photo = new File(getCacheDir(), FOLDER_NAME+File.separator+timeStamp+".png");
}
if (photo != null)
{
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
selectedImageUri = Uri.fromFile(photo);
startActivityForResult(intent, CAPTURE_IMAGE_CALLBACK);
}
}
You can get image Uri in selectedImageUri variable . (Image is stored in Sdcard)
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
switch (requestCode)
{
case CAPTURE_IMAGE_CALLBACK:
break;
}
}
Have you tried setting quality in the intent?
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, 0);
