How to remove auto focus/keyboard popup of a field when the screen shows up?

go to your application manifest file, and write this line for that activity you want to disable auto keyboard pop-up.

android:windowSoftInputMode="stateHidden"

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

call the above method inside onCreate().It prevent softKeyboard to show unless user select EditText by tapping or clicking.

or simply add android:windowSoftInputMode="stateHidden" in Activity tag in Manifest.xml

getWindow().setSoftInputMode(WindowManager.
                             LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

in onResume()

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editTextField.getWindowToken(), 0);
