Yes, If you not selected any Image and simply come back from the Gallery , It will return null in the Intent Data. Check data!=null before taking getData()
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_CAMERA) {
try {
bitmap = (Bitmap) data.getExtras().get("data");
pro_img.setImageBitmap(bitmap);
img = getEncoded64ImageStringFromBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == PICK_IMAGE_GALLERY) {
try {
if(data!=null)
{ // user selects some Image
filePath = data.getData();
if (filePath != null) {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), data.getData());
pro_img.setImageBitmap(bitmap);
img = getEncoded64ImageStringFromBitmap(bitmap);
}
}
else
{ // user simply backpressed from gallery
}
} catch (IOException e) {
e.printStackTrace();

MediaPlayer doesn't work?

I want to play audio files with MediaPlayer. Audio files are not in resource.
What I want to do is like this.
get the file path.
register the file path to realm db.
fetch the file path from realm db.
set the file path to MediaPlayer (IOException happens here)
play
IOException happens When I call MediaPlayer#setDataSource(path).
I dont know where i am doing wrong
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_choose) {
Intent intent = new Intent();
intent.setType("audio/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 999);
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 999 && resultCode == RESULT_OK) {
final Uri uri = data.getData();
_realmObj.executeTransactionAsync(new Realm.Transaction() {
#Override
public void execute(Realm bgRealm) {
MyDb db = bgRealm.where(Song.class).equalTo("id", songIndex).findFirst();
db.setSongPath(uri.getDataString());
}
}, new Realm.Transaction.OnSuccess() {
#Override

buttonPlay.setVisibility(View.VISIBLE);
}
});
}
super.onActivityResult(requestCode, resultCode, data);

Call Google Place Api on EditText

I am using google place API in my app and it's working perfectly when using fragment but, I want to call all the functionality on click on EditText. How to call that?
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
mGoogleApiClient = new GoogleApiClient
.Builder(this)
.addApi(Places.PLACE_DETECTION_API)
.enableAutoManage(this, this)
.build();
try {
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
#Override
public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
}
likelyPlaces.release();
}
});
If I am commenting this code from PlaceAutoCompleteFragment to before try block, yet it's working, so I don't understand from where it's is working and how to correct that:
PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
#Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
// Log.i(TAG, "Place: " + place.getName());
}
#Override
public void onError(Status status) {
// TODO: Handle the error.
//Log.i(TAG, "An error occurred: " + status);
}
});
try {
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
.build(this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
Here I am calling ActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
Place place = PlacePicker.getPlace(data, this);
String toastMsg = String.format("Place: %s", place.getName());
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
}
}
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = PlaceAutocomplete.getPlace(this, data);
//Log.i(TAG, "Place: " + place.getName());
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(this, data);
// TODO: Handle the error.
// Log.i(TAG, status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
}
}

Get country code from PlaceAutocomplete android (Google Places API)

We are using Google PlaceAutocomplete for city picker. We need to get country code for picked city. I am trying to use place.getLocale() but its null. Is there a way I can get Country ISO code from PlaceAutocomplete returned data.
in gradle:
compile 'com.google.android.gms:play-services-places:10.0.1'
code:
private void openCityPicker() {
try {
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_CITIES)
.build();
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
.setFilter(typeFilter)
.build(this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
com.google.android.gms.location.places.Place googleApiPlace = PlaceAutocomplete.getPlace(this, data);
Log.d(TAG, "onActivityResult: " + googleApiPlace.getAddress());
Log.d(TAG, " googleApiPlace.getLocale().getCountry(): " + googleApiPlace.getLocale().getCountry());
Log.d(TAG, " googleApiPlace.getLocale().getDisplayCountry(): " + googleApiPlace.getLocale().getDisplayCountry());
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(this, data);
// TODO: Handle the error.
Log.i(TAG, status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
}
}

late but right answer
you can get country code using this
add Place.Field.ADDRESS_COMPONENTS field into your fields list
List<Place.Field> fields = Arrays.asList(Place.Field.ADDRESS_COMPONENTS);
Intent intent = new Autocomplete.IntentBuilder(
AutocompleteActivityMode.FULLSCREEN, fields)
.setTypeFilter(TypeFilter.CITIES)
.build(mActivity);
startActivityForResult(intent, requestCode);
when you get the result into onActivityResult() you'll get full details of location into that you will find country
if (place.getAddressComponents() != null) {
List<AddressComponent> addressComponents = place.getAddressComponents().asList();
for (int i = 0; i < addressComponents.size(); i++) {
if (addressComponents.get(i).getTypes().get(0).equals("country")) {
countryCode = addressComponents.get(i).getShortName();
break;
}
}
}

Google place picker api, occur error in the searching process

Good Day,
I'm trying to use place picker api. From google.
public void onPickButtonClick(View v) {
// Construct an intent for the place picker
try {
PlacePicker.IntentBuilder intentBuilder =
new PlacePicker.IntentBuilder();
Intent intent = intentBuilder.build(this);
// Start the intent by requesting a result,
// identified by a request code.
startActivityForResult(intent, REQUEST_PLACE_PICKER);
} catch (GooglePlayServicesRepairableException e) {
// ...
} catch (GooglePlayServicesNotAvailableException e) {
// ...
}
#Override
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
if (requestCode == REQUEST_PLACE_PICKER
&& resultCode == Activity.RESULT_OK) {
// The user has selected a place. Extract the name and address.
final Place place = PlacePicker.getPlace(data, this);
final CharSequence name = place.getName();
final CharSequence address = place.getAddress();
String attributions = PlacePicker.getAttributions(data);
if (attributions == null) {
attributions = "";
}
mViewName.setText(name);
mViewAddress.setText(address);
mViewAttributions.setText(Html.fromHtml(attributions));
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
But it result in that after launching the application loading the places. It just flash and turn white and return to the page where i launch this application.
Thank You In Advance
