Camera stops, bitmap is null
New on android, i have one button to open gallery select a picture and display it into an imageview, which works properly, and another button to open the camera using Intent, i can open the camera take a picture but after clicking save image the app crashes. The image taken is saved in the correct folder. and when debbugin the app the error thrown its on this line:
filePath = data.getData();
and bitmap shows it as null. I have added the permissions and i have read many post about this but still can't figure it out what is the problem. Any help is appreciated. Here's the code.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == CAM_REQUEST && resultCode == Activity.RESULT_OK ){
Toast.makeText(TerminosYC.this.getActivity(), "si hay foto", Toast.LENGTH_LONG).show();
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
areaLeyendaImagen.setVisibility(View.VISIBLE);
areaFotoCargada.setVisibility(View.VISIBLE);
imagencargada.setVisibility(View.VISIBLE);
textoimagencargada.setVisibility(View.VISIBLE);
area_cerrarIagen.setVisibility(View.VISIBLE);
cerrarImagen.setVisibility(View.VISIBLE);
areaLeyendaImagen.setFocusableInTouchMode(true);
areaLeyendaImagen.requestFocus();
areaLeyendaImagen.setFocusable(true);
buttonChoose.setError(null);
} catch (IOException e) {
e.printStackTrace();
}
}else if (requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK ) {
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
areaLeyendaImagen.setVisibility(View.VISIBLE);
areaFotoCargada.setVisibility(View.VISIBLE);
imagencargada.setVisibility(View.VISIBLE);
textoimagencargada.setVisibility(View.VISIBLE);
area_cerrarIagen.setVisibility(View.VISIBLE);
cerrarImagen.setVisibility(View.VISIBLE);
buttonChoose.setError(null);
} catch (IOException e) {
e.printStackTrace();
}
}
}
public String getPath(Uri uri) {
Cursor cursor = getActivity().getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
String document_id = cursor.getString(0);
document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
cursor.close();
cursor = getActivity().getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
cursor.moveToFirst();
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
return path;
}

UPDATE:
Once the picture is attached on the imageview, and i click on a button to send the picture to store it in a db, i get this error.

try this
values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, CAMERA_CLICK_RESULT);
and on onActivityResult
if (requestCode == CAMERA_CLICK_RESULT && resultCode == RESULT_OK) {
Bitmap photo = null;
try {
photo = MediaStore.Images.Media.getBitmap(
getContentResolver(), imageUri);
} catch (IOException e) {
e.printStackTrace();
}
}

I think problem is here ,, intead of this
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);
change like this
Bitmap bitmap = (Bitmap) data.getExtras().get("data");

You can get Bitmap When REQUEST_CAMERA
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
You can get Bitmap When PICK_IMAGE_REQUEST from gallery
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(mcontext.getContentResolver(), uri);
// Log.d(TAG, String.valueOf(bitmap));
} catch (Exception e) {
e.printStackTrace();
}

I don't know what your codes do. But, the log says that: the application has been crashed because of null pointer exception.
Check the main method of ZygoteInit.java class . At 1120 line, you try to get something from null instance.
You should fix this.
