i worte an Android Application with google Maps integration.
I found a tutorial in youtube and did it in that way like in the video to search a location with button click.
I have just simple plaintext and a button for search. The Button is set to the onclick method onSearch() you can find code bellow.
When i press on that button, the app is crashing. What is wrong in the Code??
Thank you in advance:
public void onSearch(View v){
//Textfield in google maps activity
EditText location_tf=(EditText) findViewById(R.id.TFadress);
//Put the written input into a string to work with
String location = location_tf.getText().toString();
//List for Geocoder
List<Address> addressList= null;
if(location!= null || !location.equals("")){
Geocoder geocoder = new Geocoder(this);
try {
addressList=geocoder.getFromLocationName(location,1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addressList.get(0);
LatLng latLng= new LatLng(address.getLatitude(), address.getLongitude());
mMap.addMarker(new MarkerOptions().position(latLng).title("Searched Location"));
//MovetheCamera to the searched location with 18 zoom
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 18));
}
}

When I start the APK on my phone, everything works so far. Only when the game is over, and I start the game from scratch, comes in the Logcat always an error message and the app ended.
This code is linked via onClick button, so I think there should be somewhere the error somewhere
public void playAgain(View view) {
Button playAgainButton = (Button) findViewById(R.id.playAgainButton);
TextView winnerTextView = (TextView) findViewById(R.id.winnerTextView);
playAgainButton.setVisibility(View.INVISIBLE);
winnerTextView.setVisibility(View.INVISIBLE);
android.widget.GridLayout gridLayout = (GridLayout) findViewById(R.id.gridLayout);
for(int i=0; i<gridLayout.getChildCount(); i++) {
ImageView counter = (ImageView) gridLayout.getChildAt(i);
counter.setImageDrawable(null);
}
for (int i=0; i<gameState.length; i++) {
gameState[i] = 2;
}
activePlayer = 0;
gameActive = true;
}
Instead of the app starting over, it closes and this error message comes:

I have a Fragment attached to MainActivity. This Fragment has a RecyclerView whose Items are binded through an Adapter.
In the Adapter I listen on a click on an Item (row in recyclerView) and create an Intent to an Activity (YoutubePlayerActivity). When switching an TransactionTooLargeException occurs.
I just don´t know why this occurs...is a standard task that I want to switch from Fragment to an Activity. I´m not sending any Extras through the Intent. Just creating the Intent and saying startActivity() or startActivityFromFragment).
Any Ideas?
holder.cardView.setOnClickListener {
val intent = Intent(context.activity, YoutubePlayerActivity::class.java)
context.activity!!.startActivityFromFragment(context, Intent(context.activity, YoutubePlayerActivity::class.java), 876)
}

I'm a novice coder and I've been trying to learn how to code for school in a few days and one thing I like to do is try and deconstruct other code to learn it better. So I was looking at trying to make a contact picker and I found a tutorial online, however, the code does not work, and I don't really understand what the error message means.
My code:
public class ContactActivity extends AppCompatActivity {
private static final int RESULT_PICK_CONTACT = 85500;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);
}
public void pickContact(View v)
{
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// check whether the result is ok
if (resultCode == RESULT_OK) {
// Check for the request code, we might be usign multiple startActivityForReslut
switch (requestCode) {
case RESULT_PICK_CONTACT:
contactPicked(data);
break;
}
} else {
Log.e("MainActivity", "Failed to pick contact");
}
}
/**
* Query the Uri and read contact details. Handle the picked contact data.
* #param data
*/
private void contactPicked(Intent data) {
Button b1 = findViewById(R.id.button);
Button b2 = findViewById(R.id.button2);
Cursor cursor = null;
try {
String phoneNo = null ;
String name = null;
// getData() method will have the Content Uri of the selected contact
Uri uri = data.getData();
//Query the content uri
cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
// column index of the phone number
int phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
// column index of the contact name
int nameIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
phoneNo = cursor.getString(phoneIndex);
name = cursor.getString(nameIndex);
// Set the value to the textviews
b1.setText(name);
b2.setText(phoneNo);
} catch (Exception e) {
e.printStackTrace();
}
}
}

So I see the line " Caused by: java.lang.IllegalArgumentException: Can only use lower 16 bits for requestCode " and I think that this is the problem. Is there something with the Result_Pick_Contact or what?
Layout Visual
Try using a smaller positive RESULT_PICK_CONTACT value
private static final int RESULT_PICK_CONTACT = 24;
As specified by this answer
You need to pass a positive number to startActivityForResult.
I am trying to update text after a Dialog is dismissed. I am using an OnDismissListner, because the code in my onTextClicked runs only when the textView is clicked, and not when the dialog is dismissed.
public class AddReminder extends AppCompatActivity
{
}
#Override
protected void onCreate(Bundle savedInstanceState) {
//oncreate code
}
public void onDateClick(View view) {
loadMap();
DialogFragment datefragment = new DatePickerFragment();
datefragment.show(getFragmentManager(), "DatePicker");
Dialog dialog = datefragment.getDialog();
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
updateText();
}
});
}
public void updateText(){
TextView date = findViewById(R.id.tv_date);
String text =AddReminder.monthmap.get(DatePickerFragment.month)+" "+DatePickerFragment.day+", "+DatePickerFragment.year;
date.setText(text);
TextView time = findViewById(R.id.tv_time);
String tvdate = TimePickerFragment.hour + ":" + TimePickerFragment.min;
time.setText(tvdate);
}
When I to click the textView with the onDateClicked methodcode, the app crashes with the error:

Is there a better way to run code when the dialog is dismissed? I have tried this, but I really don't understand how to solve it.
Hello i have a question that is the one which i put in title.
I have this example that i extract from my code
String text = "Test";
EditText editText = (EditText) findViewById(R.id.idField);
editText.setText(text);
And I can't convert int o charSequence
My objective is put a string into the editText.setText();
Here is my onCreate:
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
try {
fileExist();
sessionTimeOut();
passwordValidation(getLocalPassword());
} catch (FileNotExistException e) {
setLoginActivity();
} catch (SessionTimeOutException e) {
String text="Sometext";
EditText editText = (EditText) findViewById(R.id.usernameField);
setLoginActivity(R.string.sessionOut);
editText.setText(text);
} catch (PasswordInvalidException e) {
setLoginActivity(R.string.criterios);
}
setWelcomeBackLayout();
}
The error is located where editText.setText(text); is located
There is my error:

Check your layout xml file, you editText variable is null because your reference "idField" is incorrect.
Don't forget to call setContentView(R.layout.yourlayout) before you get the reference of your view.
UPDATE
You forgot to call to setContentView method
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout_file);
...
String implements CharSequence so String.valueOf(aInt) does works as argument.
