I have an activity where click of button camera activity is launched . Sometimes onActivityResult is called and sometimes not . Even after restarting the device the onActivityResult is not called nor does it restart the current activity . Any solution to this weird behavior ?
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
String imageUri = data.toURI();
Uri uri = Uri.parse(imageUri);
try {
mBitmap = Media.getBitmap(getContentResolver(), uri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// if result is ok returns the bitmap
// mBitmap = (Bitmap) data.getExtras().get("data");
mImageView.setImageBitmap(mBitmap);
new Thread(postTheImage).start();
} else {
Toast.makeText(getApplicationContext(), "Error during capturing the image", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == R.id.capture_image_button) {
// Open the camera to capture the image
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}
You are not providing the camera activity with the information it requires. You need to supply it a file URI.
Please refer to the following
onActivityResult returned from a camera, Intent null

i have a Activity for Upload image from gallary or camera to server.image upload from camera is fine but upload from gallary is not done.i have a error showing
BitmapFactory﹕ Unable to decode stream: FileNotFoundException
i want to do when i pick up the image from gallary it is shown in other Activity on image view.
i don't know how to get fileuri for gallary please help me.
my code:
loadimage = (ImageView) findViewById(R.id.profilpic);
loadimage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
/* Intent i = new Intent(Tab1.this, ImageMain.class);
startActivity(i);*/
// selectImageFromGallery();
AlertDialog.Builder builder = new AlertDialog.Builder(Tab1.this);
builder.setMessage("Select Image From")
.setCancelable(true)
.setPositiveButton("camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_REQUEST);
}
})
.setNegativeButton("gallary", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {

}
});
AlertDialog alert = builder.create();
alert.show();
}
});
Hear is my onActiivityResult

}
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

this code is working on Google Nexus 4.4.4, but this same code is not working on Moto G 4.4.4.
I also used debugger but in the Moto G onActivityResult is not called.
Use this code:
ImageView profile=(ImageView)findviewById(R.id.imageview);
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, code);
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == code) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
try {
bmp = BitmapFactory.decodeStream(getContentResolver()
.openInputStream(selectedImage));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
profile.setImageBitmap(bmp);
}
}
}
For working on all devices you don't have to put Extra in intent, and you need to get the path of image inside OnActivityResult method, Example:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode==CAMERA_REQUEST) {
if (resultCode == RESULT_OK) {
if (data.hasExtra("data")) {
// retrieve the bitmap from the intent
bitmap = (Bitmap) data.getExtras().get("data");
Cursor cursor = getActivity().getContentResolver().query(Media.EXTERNAL_CONTENT_URI,new String[] {
Media.DATA,
Media.DATE_ADDED,
MediaStore.Images.ImageColumns.ORIENTATION },
Media.DATE_ADDED, null, "date_added ASC");
if (cursor != null && cursor.moveToFirst()) {
do {
Uri uri = Uri.parse(cursor.getString(cursor.getColumnIndex(Media.DATA)));
selectedImagePath = uri.toString();
} while (cursor.moveToNext());
cursor.close();
}
Log.e("path of the image from camera ====> ",selectedImagePath);
public void callCamera() {
//access to camara
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
I am using multiple buttons with OnClickListener() that when clicked startActivityForResult(). In the OnActivityResult() method, there are different actions to be performed. How do I get the right button to go the the right result?
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.camImgButton:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, picture);
break;
case R.id.galImgButton:
i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(i, REQUEST_CODE);
break;
case R.id.txtButton:
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
switch ( ) {
case :
if (resultCode == RESULT_OK) {
// We need to recyle unused bitmaps
if (bmp != null) {
bmp.recycle();
}
Bundle extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
display.setImageBitmap(bmp);
break;
case :
InputStream stream = null;
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
try {
// We need to recyle unused bitmaps
if (bmp != null) {
bmp.recycle();
}
stream = getContentResolver().openInputStream(data.getData());
bmp = BitmapFactory.decodeStream(stream);
display.setImageBitmap(bmp);
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
if (stream != null)
try {
stream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
you can start activity for result with different request codes for each button, and in your OnActivityResult method check for the requestCode sent back and match it with the action you want, which I think you already have in your code
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
e.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
uri=f.getAbsolutePath();
//this is the url that where you are saved the image
}
}
I want to upload image from my phone gallery into my application .In my application there is button named upload. when i click button,it should move to gallery and in gallery if i select image that selected image should display as thumbnail in application.I want to upload 10 images, from gallery in my application.
On click of the gallery button, start startActivityForResult as follows:
startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), GET_FROM_GALLERY);
Consequently, detect GET_FROM_GALLERY (which is a static int, any request number of your choice e.g., public static final int GET_FROM_GALLERY = 3;) inside onActivityResult.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//Detects request codes
if(requestCode==GET_FROM_GALLERY && resultCode == Activity.RESULT_OK) {
Uri selectedImage = data.getData();
Bitmap bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
To view gallery:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),REQUEST_CODE);
and to use it in your app:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
switch (requestCode) {
case REQUEST_CODE:
if (resultCode == Activity.RESULT_OK) {
//data gives you the image uri. Try to convert that to bitmap
break;
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.e(TAG, "Selecting picture cancelled");
}
break;
}
} catch (Exception e) {
Log.e(TAG, "Exception in onActivityResult : " + e.getMessage());
}
}
This is the way to go:
startActivityForResult(
new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI
),
GET_FROM_GALLERY
);
