Switch crashes when clicked on Android 5.0

android-switch

When clicking on a switch in my app in Android 5.0 the app crashes with the logcat shown below. The logcat doesn't reference my code anywhere in it, and this switch has worked fine on all previous versions. The switch appears invisible except for the background color and only crashes once clicked on.

After testing, the same thing happens whether I define a setOnCheckedChangeListener function or not. Even if the switch is in the layout but never in the code it will still crash when clicked on.

One of the switches in question:

<Switch
    android:layout_width="90dp"
    android:layout_height="wrap_content"
    android:textOff="Airborn"
    android:textOn="Direct Contact"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:id="@+id/switchWind"/>

And here's how I reference it.

// Doesn't actually matter since same thing happens without this
Switch sWind = (Switch) findViewById(R.id.switchWind);
sWind.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton v, boolean isChecked) {
        // Won't reach here
    }
});

Logcat:

Why does my game keep crashing Android?

This usually occurs when your Wi-Fi or cellular data is slow or unstable, causing apps to malfunction. Another reason for Android apps crashing can be a lack of storage space in your device. This can occur when you overload your device's internal memory with heavy apps.

What causes an app to crash?

Mobile apps crash for many different reasons. Sometimes, they are the result of inadequate app testing, poor memory management, or even device incompatibility. Irrespective of the error source, certain best practices can help you keep your app up at all times on most devices.
