Help inserting clock into app - Android Q&A, Help & Troubleshooting

Hello. I was wondering if someone might be able to help me figure this out. I use a program called Channels DVR for TV / DVR. I wasn't happy with the stock color theme of purple, so I spent quite a bit of time decompiling the app, editing the color codes, and threw together a much more pleasant theme. Now I would like to change the app logo displayed at the top left to a clock. I have identified the code for the logo, and have been trying to hack around the textClock in, and just can't figure it out. I was wondering if someone smarter than me might help me out.
Here's a picture of the UI, what I'm trying to replace. The logo at the top left.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And here is the code for the sidebar on the left:
Code:
<?xml version="1.0" encoding="utf-8"?>
<com.getchannels.android.ui.SideBar android:background="@color/background" android:layout_width="@dimen/sidebar_closed_width" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
<androidx.constraintlayout.widget.Guideline android:orientation="vertical" android:id="@id/sidebar_guideline" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintGuide_begin="@dimen/sidebar_closed_width" />
<androidx.constraintlayout.widget.Guideline android:orientation="vertical" android:id="@id/sidebar_expanded_guideline" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintGuide_begin="@dimen/sidebar_open_width" />
<ImageView android:id="@id/sidebar_logo" android:layout_width="70.0dip" android:layout_height="42.0dip" android:layout_marginTop="35.0dip" android:src="@drawable/logo" android:adjustViewBounds="true" android:alpha="0.0" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toLeftOf="@id/sidebar_expanded_guideline" app:layout_constraintTop_toTopOf="parent" />

<include android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="16.0dip" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" layout="@layout/sidebar_button" />
<include android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="16.0dip" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" layout="@layout/sidebar_button" />
</LinearLayout>
<include android:id="@id/sidebar_btn_settings" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="16.0dip" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" layout="@layout/sidebar_button" /></com.getchannels.android.ui.SideBar>
This portion of code that is for the logo:
Code:
<ImageView android:id="@id/sidebar_logo" android:layout_width="70.0dip" android:layout_height="42.0dip" android:layout_marginTop="35.0dip" android:src="@drawable/logo" android:adjustViewBounds="true" android:alpha="0.0" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toLeftOf="@id/sidebar_expanded_guideline" app:layout_constraintTop_toTopOf="parent" />
I've just been reading the examples for TextClock when I google 'TextClock Android', and trying to write something in, in place of the original code. The app just crashes shortly after launch so I'm obviously not making the correct changes.
Any ideas?

Have you placed some drawable resource for that logo in proper folders?

---

yes that logo is already present in the drawable folder from the original code. I'm trying to take out that line of code to display the logo and instead display a clock so I guess it wouldn't matter if that were there or not I'm going to leave it anyways because it's used other places but just that one line of code that says image view and has the source for the logo I need to change that one line, and I'm trying to use either textclock or digitalclock or textview and I just can't figure it out cuz I'm stupid
