I import
androidx.appcompat.app.AppCompatActivity,
androidx.fragment.app.Fragment,
androidx.fragment.app.FragmentManager
and I used following transactions to beginning a fragment into a FrameLayout on Main Activity
FragmentManager fm = new AppCompatActivity().getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmen_container);
if(fragment==null){
fragment= new CrimeFragment();
fm.beginTransaction().add(R.id.fragmen_container,fragment).commit();
}
but my activity destroyed.

Hello I think your problem is here
FragmentManager fm = new AppCompatActivity().getSupportFragmentManager();
try this
FragmentManager fm = getSupportFragmentManager();

I have set up the button such a way that upon the click of a button it will send a call. when the button is clicked the app crashes. Please Help me debug this. Please suggest if there are alternative ways i can code a button to send a call directly upon clicking on it. I have granted permission in the settings as well.

Try adding READ_PHONE_STATE permission in manifest as well as ask it before click.
android.permission.READ_PHONE_STATE
Also surround your code inside click with try - catch having ActivityNotFoundException handling

I've tried to add: (I also added the PATH_TO_FX Path-variable)
--module-path ${PATH_TO_FX} --add-modules javafx.controls,javafx.fxml
to the run configurations VM-options but it only changed the error I had before this error. I tried to do this on Windows AND on Linux, neither works.
Intellj shows me that every thing works, but it doesn't.
I wanted to use netbeans or eclipse but I don't know how to add libraries to them.
That would helb me to.
Example code:
import javafx.application.Application;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class AppL extends Application {
#Override
public void start(Stage stage) throws Exception {
WebView v = new WebView();
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Thanks to anyone who wants to help me, and who doesn't lauph on my english-scills😊
I am trying out gridgain for the first time and facing some issues with serialization. While trying to use GridClosure to project jobs on different nodes I get marshaling exception . On debugging, It seems the failure is always for Apache log4j Logger object. Its difficult for me to avoid loggers and wanted to understand if this is a known issue or someway I can remedy this. I have requireSerializable set to false for my grid config.

Can you make Log4J object static so it does not affect serialization? If not, GridGain allows you to inject logger resource into pretty much anything, including closures. You can configure GridLogger as GridLog4jLogger in GridConfiguration.
Here is an example:
GridRunnable run = new GridRunnable() {
// Can be any logger, including GridLog4jLogger.
#GridLoggerResource
GridLogger log;
#Override public void run() {
log.info("Hello");
// Do some logic.
}
}
or
// Can be any logger, including GridLog4jLogger
final GridLogger log = grid.log();
GridRunnable run = new GridRunnable() {
#Override public void run() {
log.info("Hello");
// Do some logic.
}
}
For more information, refer to Resource Injection page in GridGain documentation.
I am trying to access initialize method of another calss from a different class.But I am getting nullpointer Exception while returning ctroller
THis is the code I am trying to call from my second calss.
Line1- FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/src/myjavfxapp/controller/EditClientDetails.fxml"));
Line 2- EditClientDetailsController fooController = (EditClientDetailsController) fxmlLoader.getController();
Line3- fooController.initialize(null, null);
I am getting null pointer exception at line number 3.

My Intention is to initialize the "EditClientDetails.fxml" fields from different controller class.
Please point out if i missed anything.
Try the below example it working fine, you have to use load() function of FxmlLoader class.
public class Xxx extends Application {
#Override
public void start(Stage stage) throws Exception {
//Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
FXMLLoader loader = new FXMLLoader(getClass().getResource("Sample.fxml"));
Parent root = (Parent)loader.load();
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
SampleController controller = (SampleController)loader.getController();
}
public static void main(String[] args) {
launch(args);
}
}
