Android Toast message doesn't show

Question

I know there are some other issues regard this problem, however, mine is surprisingly different (at least I think so).

I guess my code is right but I don't have idea why toast message doesn't display. Firstly, I couldn't see toast message in my Fragments. Then I decided to put it in my activity and amazingly it doesn't display here too.

This is code of my Activity which has been extended from FragmentActivity.

@Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        Log.d(TAG, "***************************");
        Log.d(TAG, "*** Application started ***");
        Log.d(TAG, "***************************");

        // assign layout to activity
        setContentView(R.layout.activity_main);

        mContext = MainActivity.this;
        Toast.makeText(mContext, "Hello World", Toast.LENGTH_SHORT).show();

.
.
.
} 

Application works fine without error and just this f.toast message doesn't display! I even replaced mContext with getApplicationContext() and I had same result, toast does not display.

Any suggestion would be appreciated. Thanks

I assume you see those 3 logs in your logcat? Try cleaning your project. – Breadboard

I can't reproduce the issue. Are you sure you're not just missing it? Try changing Toast.LENGTH_SHORT to Toast.LENGTH_LONG – Stearn

@XaverKapeller, Thanks bro. I remember Eclipse had this problem that we needed to clear project, restart and rebuild again. For sake of experience I did it but still have nothing!!!! When I'm opening Toast class there are some red lines that I don't know is because of them. let me update my question with image. – Ammoniac

Those errors don't matter. They are normal since those two classes most likely have package visibility. You don't have to bother looking at framework classes... – Breadboard

If you are trying on emulator, then try it on real device else no problem. – Bibliolatry

Thanks Osama, I'm on real device. But good point let me test on other device. – Ammoniac

@OsamaMohammedShaikh, Your suggestion was valuable to me. I tested on Android 4.3 It was working fine. My device is 4.1.2 but doesn't display. How come? I'm able to display toast message on my other apps? omg... – Ammoniac

I don't know but sometimes old software becomes buggy. – Bibliolatry

Answer 1

Perhaps you have accidentially disabled notifications for your app in the settings? This causes no toasts too.

Exactly, have no idea when I did it. Anyways, thanks after 3-4 hours rotating around myself finally you told me the reason. Thanks... – Ammoniac

Now I know why my users can't see any hint from my app. I thought that was my fault. – Guide

I disabled notifications for all apps, but I uninstall the app and reinstall it and now it works... ?¿ – Disturbance

Answer 2

something may be hiding your toast...so I use this when that appears to be the case:

    Toast toast = Toast.makeText(TaskEdit.this, "Task Saved", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.CENTER_HORIZONTAL,0,0);
    toast.show();

You can change the position of the toast location using the various setGravity options available. Happy Coding.

I also faced this problem. My problem was that a particular emulator was not showing any toast message although other emulators and real devices were. I could solve the problem after closing the emulator and removing folder <YourUserName>\.android\avd\<EmulatorName>.avd\snapshots.

Answer 4

Try replacing mContext with "this," at least that is how i have been using it... Rather than typing the extra lines of code you can simplify, seeing you are within the MainActivity already.
