Application crashes when EditText is touched in android

Question

When the EditText view is empty, I can touch it and start entering data. But when I touch it while some data is typed, application crashes, giving following stack trace:

    E/InputEventReceiver: Exception dispatching input event.

I am not sure which code should I provide, because I have several classes and already complicated logic, so I think I should first understand what the problem could really be.

Here is xml code for the EditText :

<EditText
    android:id="@+id/input"
    android:importantForAutofill="no"
    android:textSelectHandle="@null"
    android:visibility="visible"
    android:layout_width="180dp"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentTop="true"
    android:background="@drawable/rounded_field"
    android:inputType="number"
    android:textCursorDrawable="@null"
    android:padding="8dp"
    android:layout_marginTop="12dp"
    android:layout_marginBottom="16dp"
    android:textSize="22sp"
    tools:ignore="LabelFor" />

Answer 1

I got it. When I've changed these lines:

android:textSelectHandle="@null"

and

android:textCursorDrawable="@null"

Everything got back to normal. I should've used transparent presets or something instead of @nulls.

Answer 2

The reason android:textSelectHandle="@null" is not desired is because when you click on a point in editable text, a pointer appears. Setting it to @null will prevent it from appearing since there is no such resource corresponding to that parameter, which causes the program to crash. Set it to "@android:color/transparent" .
