[MaterialAlertDialog] The style on this component requires your app theme to be Theme.AppCompat

Description: I’m having random crashes when trying to create MaterialAlertDialog. The message: The style on this component requires your app theme to be Theme.AppCompat This is happening in some devices while is not happening in others, for instance I have an A71 Android 10, and is ok, but Crashlytics reports too many so far all related to the same issue and there are also A71 reported in Crashlytics with the same issue. I’m setting a custom view into the Alert Dialog and in some instances I’m creating the Builder from a static Utility class that I can use across the application.

The source code below is from one of the cases, but I still have many issues with other Alert Dialog related to the same. This is a major issue for me, because is the source of too many crashes and I literally can’t reproduce with my devices, I’m aware of the crashes only for user reports and crashlytics.

Expected behavior: The dialog should show without any issue.

Source code:

    public void showChoiceDialog() {
        View randomGeneratorView = View.inflate(this, R.layout.alert_dialog_random_generator, null);
        TextInputEditText presidentName = randomGeneratorView.findViewById(R.id.random_presidents_picker_name);
        presidentName.setText(Utilities.getSharedPreferences(this).getString(SP_CARD_NAME, EMPTY_STRING));
        NumberPicker presidentsPicker = randomGeneratorView.findViewById(R.id.random_presidents_picker);
        presidentsPicker.setMinValue(1);
        presidentsPicker.setMaxValue(45);
        presidentsPicker.setValue(Utilities.getSharedPreferences(this).getInt(RANDOM_PICK, 1));
        new MaterialAlertDialogBuilder(this, R.style.alert_dialog_material_theme_progress_bar)
                .setTitle(R.string.generate_random_presidents_name)
                .setView(randomGeneratorView)
                .setPositiveButton(R.string.ok, (dialog, which) -> {
                    presidents.clear();
                    int randomPick = presidentsPicker.getValue();
                    generateRandomCards(randomPick, presidentName.getText() == null ? EMPTY_STRING : presidentName.getText().toString().trim());
                    Utilities.savePreferences(RANDOM_PICK, randomPick, Utilities.EDITOR_IS_INT, this);
                })
                .setNegativeButton(R.string.cancel, (dialog, which) -> {
                })
                .show();
    }

I was getting the same error when I was creating a Simple MaterialAlertDialog. This is my code:

String[] items = {"Select from Gallery"};
new MaterialAlertDialogBuilder(getApplicationContext())
        .setTitle("Change Cover Photo")
        .setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                SelectImageToUpload();
            }
        }).show();

But after I change my mind, I made something else, but later I received an error in my ProgressDialog which resulted in it not displaying and it was fixed after changing the getApplicationContext() to ActivityName.this. So I thought maybe it will also fix the Simple MaterialAlertDialog. To my surprise it did. This is my code now:

String[] items = {"Select from Gallery"};
new MaterialAlertDialogBuilder(ActivityShopDetail.this)
        .setTitle("Change Cover Photo")
        .setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                SelectImageToUpload();
            }
        }).show();

I’m still a noob in terms of programming in Android so feel free to criticize my code or whatever you want to criticize 😅😅😅

I had this problem due to the fact that I used injected context (ApplicationContext) from dagger hilt
