Im trying to use vector drawables on pre lollipop devices. I did all as instructed here but i still get this crash.

build.gradle:

Answer 1

I'm surprised that this is not mentioned here yet.

This crash happens often with:

android:drawableRight
android:drawableLeft
android:drawableTop
android:drawableBottom
android:drawableStart
android:drawableEnd

A common fix is to create another drawable that wraps the drawable with , or to set the compound drawable using code, but nowadays you can instead use:

app:drawableRightCompat
app:drawableLeftCompat
app:drawableTopCompat
app:drawableBottomCompat
app:drawableStartCompat
app:drawableEndCompat

This was added to AppCompatTextView in appcompat 1.1.0-alpha01.

To use the attribute I've had to use AppCompat views instead of usual ones, eg. I've used AppCompatButton instead of Button.

Not sure if you set vectorDrawables.useSupportLibrary true and AppCompatDelegate.setCompatVectorFromResourcesEnabled(true) (I have both). Check this article from Nick Butcher: https://medium.com/androiddevelopers/using-vector-assets-in-android-apps-4318fd662eb9.
