Make TextView automatically delete old text?

Question

I am using a TextView for log purposes inside an Android app, and if it gets too long the app becomes unstable. Is it possible to set a max limit so TextView removes old text after it gets to a certain size? If not I can set the app to automatically clear the text once a day. If I want to clear the text manually, do I call TextView.clearComposingText(); ?

Don't you think using a file for logs will be a better idea ? — Vivek Mishra, Sep 03 '18 at 12:20
no, because I want to be able to see the logs conveniently. The logs are for short term only. — david, Sep 03 '18 at 12:21

Save your log's inside a file and when needed show the some part of the file inside a textview — Amir Hossein Mirzaei, Sep 03 '18 at 12:27

 <TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxLength="100"/>

Set the maximum length of the textview to a limit number and also check when to clear the textview. Write the following function in Activity and call it on onCreate.

private void checklength(){
   if(textview.getText().length()==100){
       textview.setText("");
   }
}

Hope it helps.
