Error inflating class com.google.android.material.floatingactionbutton.FloatingActionButton-CodePudding

I am getting an "Error inflating class com.google.android.material.floatingactionbutton.FloatingActionButton" when i run my application on my phone. I know there are other posts with this but its not the same or al least the answers there do not work for me.

So when i run my application on the emlulator all works great. Not error's or anything. When i run the same application on my phone (with the same android API version) i get the below error.

in other posts i have read the theme is wrong and they advice to change it to a sub of materialComponents but that is already the case for me:

Theme.MaterialComponents.DayNight.DarkActionBar

The i read somebody changing the background but i do not do that:

    <com.google.android.material.floatingactionbutton.FloatingActionButton
    android:id="@ id/floatingActionButton"
    app:srcCompat="@drawable/plus"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/margin_M"
    android:backgroundTint="?attr/colorAccent1"
    android:clickable="true"/>

In short i am lost as to the root cause specially because it works fine in the emulator. Can anybody help me with this?

CodePudding user response：

If you look lower in the stack trace, you will see this line:

E/AndroidRuntime: Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 77: TypedValue{t=0x2/d=0x7f0300e0 a=-1} ...

There is an attribute that cannot be resolved. The id is `0x7f0300e01 and, since the error points to the floating action button, the missing attribute will be referenced there.

This looks like an issue with themes. I would look at

android:layout_margin="@dimen/margin_M"
android:backgroundTint="?attr/colorAccent1"

and removed each one-by-one to isolate the problem and go from there. (This is just to isolate the problem. I am not suggesting that you don't need these values.)

Update: Actually since the following line appears in the trace

at android.content.res.TypedArray.getColorStateList(TypedArray.java:600)

I think the issue is with ?attr/colorAccent1. Check your theme for the presence of this attribute. Also, make sure that this attribute is defined as a color.
