Start action when returning from Android settings screen

My script:

  • I open an activity
  • I'm doing a check (internet check)
  • In case of a false check, launching a warning dialog
  • Now I go to the settings to go back to the Internet by clicking the Back button
  • The dialogue is not rejected, it is still on the screen.
  • My goal is to restart the activity when I return from the settings screen

CODE {Edited}

public void open(){
        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setMessage(getApplicationContext().getResources().getString(R.string.searchFilterLocationMessage));
        alertDialogBuilder.setPositiveButton(R.string.Ok, 
                new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                /*Intent intent = new Intent(Settings.ACTION_SETTINGS) ;
                this.startActivity(intent);
                 */
                startActivityForResult(new Intent(Settings.ACTION_SETTINGS), 0);


            }
        });
        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();

    }


    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == 0) {
            Intent intent = getIntent();
        finish();
        startActivity(intent);
        }
    }//onActivityResult

Run customization setup:

startActivity(new Intent(Settings.ACTION_SETTINGS));

and select the current activity in the onResume method:



public void onResume(){
super.onResume();
//Do your work
}

after setting screen support your onResume method will call and here you can get your location.

Starting Activity

with run mode singleTask

by calling startActivityForResult(intent, requestCode)

immediately returns the cancellation result. You can see in the debugger what onActivityResult()

is called even before the system settings start Activity

.

As a quick workaround, I suggest using a flag indicating whether the settings were called Activity

or not. how



  • flag setting

    private boolean flag = false;

  • using startActivity()

    isteadstartActivityForResult() 

    @Override
public void onClick(DialogInterface arg0, int arg1) {
    startActivity(new Intent(Settings.ACTION_SETTINGS));
    flag = true;
}

  • checking the flag in onResume() 

    @Override
protected void onResume(){
super.onResume();
    if (flag) {
        startActivity(new Intent(this, MainActivity.class));
        finish();
    }
}
