Why App crashes when applying color to edittext text in android?

Question

private void ShowPicker() {
    AlertDialog colorPickerDialog= new ColorPickerDialog.Builder(getContext())
            .setTitle("ColorPicker Dialog")
            .setPreferenceName("MyColorPickerDialog")
            .setPositiveButton("Confirm",
                    new ColorEnvelopeListener() {
                        @Override
                        public void onColorSelected(ColorEnvelope envelope, boolean fromUser) {
                            textEditBottomSheetCallback.SetTextColor(envelope.getColor());
                        }
                    })
            .setNegativeButton("cancel",
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            dialogInterface.dismiss();
                        }
                    })
            .attachAlphaSlideBar(true) // the default value is true.
            .attachBrightnessSlideBar(true)  // the default value is true.
            .setBottomSpace(12) // set a bottom space between the last slidebar and buttons.
            .show();
    colorPickerDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.blue));
    colorPickerDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.blue));
}
@Override
public void SetTextColor(int color) {
    edtTitle.setTextColor(ContextCompat.getColor(getContext(),color));
    edtText.setTextColor(ContextCompat.getColor(getContext(),color));
}

In show picker method I am using skydove color picker library and in set text color method I set color to edittext text. App crashes when I select color from color picker dialog. Any suggestions about this problem. Sky Dove Library

No log provided but my guess is that you are applying color to the dialog after it is being shown. Try this:

private void ShowPicker() {
AlertDialog colorPickerDialog= new ColorPickerDialog.Builder(getContext())
        .setTitle("ColorPicker Dialog")
        .setPreferenceName("MyColorPickerDialog")
        .setPositiveButton("Confirm",
                new ColorEnvelopeListener() {
                    @Override
                    public void onColorSelected(ColorEnvelope envelope, boolean fromUser) {
                        textEditBottomSheetCallback.SetTextColor(envelope.getColor());
                    }
                })
        .setNegativeButton("cancel",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialogInterface.dismiss();
                    }
                })
        .attachAlphaSlideBar(true) // the default value is true.
        .attachBrightnessSlideBar(true)  // the default value is true.
        .setBottomSpace(12); // set a bottom space between the last slidebar and buttons.
        
colorPickerDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.blue));
colorPickerDialog.show();
}
