Error inflating class ImageButton

问题

I have an app which has fragment and image button on that. The problem is it's working on and above 5.0 but not below 5.0. The min sdk version is 17.

Not getting what's wrong here. I am getting 2 exceptions.

One is RuntimeException for image button. Second is ResourceNotFoundException for fab selector file.

Log : 1st exception --

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.siddhi.timetablelayout/com.example.siddhi.timetablelayout.MainActivity}: android.view.InflateException: Binary XML file line #16:

Error inflating class ImageButton

2nd exception --

This exception

leads to the conclusion that this line <solid android:color="?attr/colorAccent" /> in fab_selector is the culprit. Try to change color to HEX value and then test.

hope this helps.

回答2:

Yes. You need to create a folder like 'drawable-v21'.

回答3:

this being a top result on google I wanted to share what solved the same error for me (although not the same issue as above)

• make sure build tools version is up to date
• I had the combination of an vector src drawable and a elevation value (API 21+ only) which seemed to trip it up. I made a separate layout for v21 to have the elevation value (but kept the vector drawable everywhere) and this solved it for me

回答4:

The format of the image.png was not OK. My solution: I installed greenshot on my PC to grab an image from my screen https://getgreenshot.org/ Then I saved the image as png file in my res/drawable. This worked for me
