i have:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_foto);
Intent intentFotocamera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); //creo un timestamp univoco
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "MyImages");
imagesFolder.mkdirs(); //creo un nuovo album
File image = new File(imagesFolder, "QR_" + timeStamp + ".png"); //concateno
Uri uriSavedImage = Uri.fromFile(image);
intentFotocamera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(intentFotocamera, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
Now, when the user presses the photo confirmation button (and then is saved locally) I would like to create a new activity because I want to print this photo in my app.
How do I create new activity?
In the override method onActivityResult() start the new activity.
https://developer.android.com/training/basics/intents/result.html
Example:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
// Check which request we're responding to
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
// The user picked a contact.
// The Intent's data Uri identifies which contact was selected.
// Do something with the contact here (bigger example below)
}
}
}
Do you want to open new activity and show the photo which is taken recently?
Here is how you can do it.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
"handle here"
}
} catch (Exception ex) {
}
}

I am writing an android application. This app is built on top of Gmail. I want to add the ability to attach files from other apps. The first app I am working on doing this with is a custom Box app (made with the box sdk). I can currently send an intent, open an activity in the Box app, pick an attachment, and return. However, in my Box-SDK app, once an item is selected, I have no idea how to turn it into data that I can properly send back to my Gmail app (or any original sender of the intent). I also do not know how to send that data back to the originator of the intent.
I know setResult() is involved, but I am not sure where to put it or how to properly use it to carry the data chosen in box into the email app.
What's currently happening is it just goes back into gmail without an attachment and says that the download has finished.
Here is the code I currently have:
private void onFileSelected(final int resultCode, final Intent data) {
if (Activity.RESULT_OK != resultCode) {
Toast.makeText(this, "fail", Toast.LENGTH_LONG).show();
}
else {
final BoxAndroidFile file = data.getParcelableExtra(FilePickerActivity.EXTRA_BOX_ANDROID_FILE);
AsyncTask<Null, Integer, Null> task = new AsyncTask<Null, Integer, Null>() {
#Override
protected void onPostExecute(Null result) {
Toast.makeText(MainActivity.this, "done downloading", Toast.LENGTH_LONG).show();
// Intent result2 = new Intent();
// result2.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + ));
// setResult(Activity.RESULT_OK, result2);
//// setResult(resultCode, data);
super.onPostExecute(result);
finish();
}
#Override
protected void onPreExecute() {
Toast.makeText(MainActivity.this, "start downloading", Toast.LENGTH_LONG).show();
super.onPreExecute();
}
#Override
protected Null doInBackground(Null... params) {
BoxAndroidClient client = ((HelloWorldApplication) getApplication()).getClient();
try {
File f = new File(Environment.getExternalStorageDirectory(), file.getName());
Intent result2 = new Intent();
result2.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + f.getAbsolutePath()));
setResult(Activity.RESULT_OK, data);
// setResult(resultCode, data);
System.out.println(f.getAbsolutePath());
client.getFilesManager().downloadFile(file.getId(), f, null, null);
}
catch (Exception e) {
}
return null;
}
};
task.execute();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == AUTH_REQUEST) {
onAuthenticated(resultCode, data);
}
else if (requestCode == UPLOAD_REQUEST) {
onFolderSelected(resultCode, data);
}
else if (requestCode == DOWNLOAD_REQUEST) {
onFileSelected(resultCode, data);
}
}
Try using a file provider:
https://developer.android.com/reference/android/support/v4/content/FileProvider.html#ServeUri
From the page:
"There are a variety of ways to serve the content URI for a file to a client app. One common way is for the client app to start your app by calling startActivityResult(), which sends an Intent to your app to start an Activity in your app. In response, your app can immediately return a content URI to the client app or present a user interface that allows the user to pick a file. In the latter case, once the user picks the file your app can return its content URI. In both cases, your app returns the content URI in an Intent sent via setResult()"
From another stackoverflow answer:
public void showCameraScreen(View view) {
// BUILT IN CAMERA
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
camera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(this)) );
this.startActivityForResult(camera, 1);
}
private File getTempFile(Context context) {
// it will return /sdcard/MyImage.tmp
final File path = new File(Environment.getExternalStorageDirectory(), context.getPackageName());
if (!path.exists()) {
path.mkdir();
}
return new File(path, "MyImage.tmp");
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
final File file = getTempFile(this);
byte[] _data = new byte[(int) file.length()];
try {
InputStream in = new FileInputStream(file);
in.read(_data);
in.close();
in = null;
//DO WHAT YOU WANT WITH _data. The byte array of your image.
} catch (Exception E) {
}
}
}
We can modify this code, where it says //Do What you want with the _data, just call
public final void setResult (int resultCode, Intent data)
I'm switching from using the default camera to finally growing a pair and deciding to make a custom camera. It's only showing me how much I don't fully understand.
Here is basically way I have been doing things in the main activity as far as photos go, but it will no longer work:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == PICK_PHOTO_REQUEST) {
if (data == null) {
Toast.makeText(this, "General Error!", Toast.LENGTH_LONG).show();
}
else {
mMediaUri = data.getData();
}
Log.i(TAG, "Media URI: " + mMediaUri);
}
else {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(mMediaUri);
sendBroadcast(mediaScanIntent);
}
(...)
Here is the picture saving function along with a couple others of the new camera:
(...)
#Override
public void onPictureTaken(byte[] data, Camera camera) {
Log.d("Picture taken");
String path = savePictureToFileSystem(data);
setResult(path);
finish();
}
private static String savePictureToFileSystem(byte[] data) {
File file = getOutputMediaFile();
saveToFile(data, file);
return file.getAbsolutePath();
}
private void setResult(String path) {
Intent intent = new Intent();
intent.putExtra(EXTRA_IMAGE_PATH, path);
setResult(RESULT_OK, intent);
}

(...)
What do I need to do so that the main activity can receive the image's URI in the onactivityresult instead of the path String? Are URIs even applicable when it comes to custom cameras?
Please and thanks.
You use custom camera, but want to do it via Intent? OK, you have the absolute file path in
String abspath = data.getExtras().getString(EXTRA_IMAGE_PATH);
mMediaUri = Uri.fromFile(new File(abspath));
I call this function:
private void TakePhoto() {
LogService.log(TAG, "inTakePicture");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/BlueSkyBio/media/", "test.jpg");
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
Which takes me on the next onActivityResult:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE) {
if(outputFileUri != null){
LogService.log("MainFragment", outputFileUri.toString());
String path = outputFileUri.toString();
selectedVideoPath = path.substring(7);
LogService.log("in take pic", "selectedImagePath: " + selectedVideoPath);
Intent paintActivity = new Intent(getActivity(), PaintActivity.class);
paintActivity.putExtra("selectedImagePath", selectedVideoPath);
paintActivity.putExtra("isVideo", false);
startActivity(paintActivity);
((FragmentActivity) getActivity()).finish();
} else{
// Toast.makeText(getActivity(), "No picture taken", Toast.LENGTH_SHORT).show();
Intent main = new Intent(getActivity(), FragmentActivity.class);
startActivity(main);
((FragmentActivity) getActivity()).finish();
}
}
}
This works ok, but if i call the intent to take a picture, and then press the back button, if i already took a picture before, it will load that picture, if not, it will crash, because by pressing back, it will not take a picture. What can i do to escape this situation?
I have tried to test:
if(data != null) // instead of: if(outputFileUri != null){
But this will never enter the "else" part of the code.
use these conditions:
private static final int CAMERA_PIC_REQUEST = 1337;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==CAMERA_PIC_REQUEST && resultCode == RESULT_OK){
log.d("something","something");
}
else if (resultCode == Activity.RESULT_CANCELED)
{
log.d("something","something");
}
}
I read an text input from the user, this input i use it as a name of a picture i'm taking by the camera.
i store this name and the path of the image name into Sqlite Database.
what I'm trying to do is, after clicking OK to accept the taken picture, i want the saved path to be displayed in a toast.
the problem is, when I click OK to accept the picture, nothing is being displayed and i cant switch from the camera activity to the activity that called the camera activity"the previous activity"
Note: I'm using the emulator not a real device.
OnClickListener btn_TakePictureListener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String imgPath = retrievePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, getImageUri(imgPath));
startActivityForResult(intent, RequestCode);
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RequestCode && resultCode == RESULT_OK) {
String s = data.getData().toString();
Toast.makeText(getBaseContext(), ""+s, Toast.LENGTH_SHORT).show();
}
}
if you are passing Uri for you image then you can retrieve image as taken by camera:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(
Environment.getExternalStorageDirectory(), "temp.jpg")));
startActivityForResult(intent, 1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
// Set the file save path with directory
File picture = new File(Environment.getExternalStorageDirectory()
+ "/temp.jpg");
Uri imageuri= Uri.fromFile(picture);
//set to imageview here
}
}
EDIT:
For Getting data uri in onActivityResult start Camra Activiyt as:
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,IMAGE_UNSPECIFIED);
startActivityForResult(intent, 2);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
Uri uriimg = data.getData();
Toast.makeText(getBaseContext(), ""+uriimg.toString(), Toast.LENGTH_SHORT).show();
}
}
In my application, I'm trying to make it so the User can press a button, which will allow them to take a picture using the stock camera application on their phone.
I am following the guide to using an external Camera app to capture images that I can use in my own app from the Android Developers Guide (http://developer.android.com/guide/topics/media/camera.html#intent-receive)
I'm having trouble with the onActivityResult() method, it apparently takes in 3 parameters
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if(resultCode == RESULT_OK) {
Log.w("borre","Image saved to:\n" + data.getData());
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
}
But at the moment, the data Intent is coming back as null, so calling any methods on the Intent parameter throws a NullPointerException
Here's the code I'm using to call up the Camera application (It's basically the same as the code in the guide)
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
Has anyone had this problem or knows why this Intent is coming back as null?
your are getting data part null bez you are not setting intent.setDataAndType() when you are starting Acitivty.like
public static final String IMAGE_UNSPECIFIED = "image/*";
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);
startActivityForResult(intent, 3);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == 0)
return;
if (requestCode == 2) {
Uri uri=data.getData(); //YOU GET DATA HERE
}
//OR
if (requestCode == 3) {
Bundle extras = data.getExtras();
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);// (0 - 100)????
imageView.setImageBitmap(photo);
}
}
or in your case getting image path use:
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
//pic path
File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg");
}
