in my camera intent:
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
this part gives me a null pointer exception.
can anyone explain why and what need to be changed??
button_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
startActivityForResult(intent, TAKE_PICTURE);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 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
}
}
}
Try the following,
public class Camera extends Activity
{
private static final int CAMERA_REQUEST = 1888;
private String selectedImagePath;
WebView webview;
String fileName = "capturedImage.jpg";
private static Uri mCapturedImageURI;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent cameraIntent = new Intent(ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_REQUEST)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
Random randomGenerator = new Random();randomGenerator.nextInt();
String newimagename=randomGenerator.toString()+".jpg";
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + newimagename);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//write the bytes in file
try {
fo = new FileOutputStream(f.getAbsoluteFile());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block

}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block

}
uri=f.getAbsolutePath();
//this is the url that where you are saved the image
}
}

This is the code i used to record video from an android device in MP4 format. The file is being created but is of 0 bytes size.
Here is my code :-

}
Uri outputFileUri = Uri.fromFile(newFile);
Intent record = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
record.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(record, 5);
}
});

Here is the Code piece for Taking a Picture through Default Camera (here I implemented Intent to to fetch the image). After that store it to SD card(here a new file will be created and the newly taken image will be stored ); and if you don't want to store then remove the saving part from code. After that you can use the file path for your upload purpose. You can then refer it and change to get the path as your wish.
In the class area put these lines
final int TAKE_PHOTO_REQ = 100;
String file_path = Environment.getExternalStorageDirectory()
+ "/recent.jpg";//Here recent.jpg is your image name which will going to take
After that invoke the camera by putting these line in calling method.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PHOTO_REQ);
then add this method in your Activity to get the picture and save it to sd card and you can invoke your upload method from here to upload the image by knowing its path.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PHOTO_REQ: {
if (resultCode == TakePicture.RESULT_OK && data != null) {
Bitmap srcBmp = (Bitmap) data.getExtras().get("data");
// ... (process image if necesary)
imageView.setImageBitmap(srcBmp);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
srcBmp.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
// you can create a new file name "test.jpg" in sdcard folder.
File f = new File(file_path);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// write the bytes in file
FileOutputStream fo = null;
try {
fo = new FileOutputStream(f);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// remember close de FileOutput
try {
fo.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.e("take-img", "Image Saved to sd card...");
// Toast.makeText(getApplicationContext(),
// "Image Saved to sd card...", Toast.LENGTH_SHORT).show();
break;
}
}
}
}
Hope this will be helpful for you and others too .. thanks
I've managed to programmatically take a photo from the camera, then display it on an imageview, and then after pressing a button, saving it on the Gallery.
It works, but the problem is that the saved photo are low resolution.. WHY?!
I took the photo with this code:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
Then I save the photo on a var using :
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
}
}
and then after displaying it on an imageview, I save it on the gallery with this function:
public void SavePicToGallery(Bitmap picToSave, File savePath){
String JPEG_FILE_PREFIX= "PIC";
String JPEG_FILE_SUFFIX= ".JPG";
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = JPEG_FILE_PREFIX + timeStamp + "_";
File filePath = null;
try {
filePath = File.createTempFile(imageFileName, JPEG_FILE_SUFFIX, savePath);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
FileOutputStream out = null;
try {
out = new FileOutputStream(filePath);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
picToSave.compress(CompressFormat.JPEG, 100, out);
try {
out.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Add the pic to Android Gallery
String mCurrentPhotoPath = filePath.getAbsolutePath();
MediaScannerConnection.scanFile(this,
new String[] { mCurrentPhotoPath }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
}
});
}
I really can't figure out why it lose so much quality while saved..
Any help please ? Thanks..
The photo you are displaying in the ImageView is a thumbnail :
data.getExtras().get("data");
Are you calling the method :
public void SavePicToGallery(Bitmap picToSave, File savePath)
with the thumbnail ?
Here you have all the steps describe to do what you want :
http://developer.android.com/training/camera/photobasics.html
data.getExtras().get("data") only get thumbnail.
To do it properly, you have to declare global uri variable
Uri imageCapturedUri ;
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
imageCaptureUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageCaptureUri);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
// mImageCaptureUri is your Uri
}
}
