how to check if a string is empty or null in Android Studio

Question

In my project I have an edit text field and its name is editText also I have assign mTextEmri = (EditText) findViewById(R.id.editText); I want to get its value and I have done it with the following statment String emridhene = mTextEmri.getText().toString();

Now I want to check it if it is null or empty I have tried this code but it is not working

if (emridhene.toString() == null || emridhene.toString() == "") {
                mTextViewKonfirm.setText("Ju lutem shkruani nje Emer");
            }
           else{
                mTextViewKonfirm.setText(emridhene);
            }

How can I make it to work. Thanks.

Just Use

if(TextUtils.isEmpty(/* your String*/)){
  // String is empty or null
}else {
  // string has value
}
