I am making an app that sends a picture taken from the Camera app however the image it returns seems to be only a thumbnail how can I get it to turn the whole image?
The following code gets an image, but it's too small.
public class OnTheJobActivity extends Activity{
private static final int CAMERA_PIC_REQUEST = 1337;
private Button takePictureButton;
private Button sendPictureButton;
private Bitmap thumbnail;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.onthejob);
takePictureButton = (Button) findViewById(R.id.takePictureButton);
takePictureButton.setOnClickListener(takePictureButtonListener);
sendPictureButton = (Button) findViewById(R.id.sendPictureButton);
sendPictureButton.setOnClickListener(sendPictureButtonListener);
}
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.photoResultView);
image.setImageBitmap(thumbnail);
sendPictureButton.setVisibility(Button.VISIBLE);
}
}
private OnClickListener takePictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
private OnClickListener sendPictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, "abc@gmail.com");
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
i.putExtra(Intent.EXTRA_STREAM, thumbnail);
i.setType("image/bmp");
startActivity(Intent.createChooser(i,"Emailfile"));
}
};
}
Try using the implementation shown here
Specifically:
Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
public void onPictureTaken(byte[] imageData, Camera c) {
}
};

You could also change the intent you're using.
//in your buttonListener
ContentValues values = new ContentValues();
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//create new Intent
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
try{
startActivityForResult(i, ACTIVITY_GET_IMAGE);
}
catch(Exception ex){
Log.v("BRE", ex.toString());
}
//in your activity
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == ACTIVITY_GET_IMAGE){
if(resultCode == RESULT_OK){
try{String uri = data.getData().toString()}
catch(NullPointerException e){//do something}
}
}
}
This will return a uri which you can then use to access the full resolution image
