Posted by Mayank Sharma on
HA HA HA !!!, You entrapped again in this error. Yes, if you are developing apps for a long time than definitely you faced this issue several times. If your answer is 'NO' than your developing skills are good or may be you didn't face it because you are a fresher. Or if answer is 'YES' than buddy, you forgot something in hurry. you know what is it ?

Error :

android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application.


Solution :

Somewhere in your alert dialog initialization. you passed context of your activity, replace it with [YourActivityName].this . That's it, your app will run perfectly after doing this. If still not working & same error occurs than ask problem in comment with detailed description. We will definitely help you to solve your issue.

    private void ShowPopup(){

    final Dialog dialog = new Dialog(mcontext, R.style.CustomDialog);
    Log.e("Dialog",""+dialog);
    // nestedScrollView.setBackgroundColor(Color.parseColor("#526565"));
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.contact_popup);
    dialog.setCanceledOnTouchOutside(false);
    dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
    contactmobile = dialog.findViewById(R.id.contact_mobile);
    contactname = dialog.findViewById(R.id.contact_name);
    ok = dialog.findViewById(R.id.ok);
    // email.setText(mPostData.get(contact.getId()).getEmail());
    // mobile.setText(mPostData.get(contact.getId()).getMobile());
    ok.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
    // Intent intent =new Intent(mcontext,LoginActivity.class);
    // mcontext.startActivity(intent);
    resend1();
    //dialog.dismiss();

    }
    });

    dialog.show();
