InflateException only on Android 4.X

Question

Before marking the question as duplicate, I already checked the other answers and nothing worked. The application works on Android >=5.0, but fails on Android 4.4.2 and probably on other Android 4.x devices.

This is the line where the crash is happening:

 @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
       View itemView = LayoutInflater.from(context).inflate(itemLayout, parent, false);
       ..........................

build.gradle

android {
    compileSdkVersion 23
    buildToolsVersion ANDROID_BUILD_TOOLS

defaultConfig {
    minSdkVersion 16
    targetSdkVersion ANDROID_TARGET_SDK
.......................
}


dependencies {
 compile 'com.android.support:appcompat-v7:23.1.0'
 compile 'com.android.support:design:23.1.0'
 compile 'com.android.support:recyclerview-v7:23.1.0'
 compile 'com.github.bumptech.glide:glide:3.5.2'
 .......................
}

I can't seem to figure out why this is happening and it's driving me nuts. I would greatly appreciate any help.

@Code-Apprentice It's an Integer. I edited the question with the whole function. — , Sep 30 '16 at 08:38
Why is it an Integer instead of an int? Where do you set is value? — Code-Apprentice, Sep 30 '16 at 08:40
In initRecyclerView() i set his value. recyclerAdapter.setItemLayout(R.layout.list_item_0); recyclerAdapter.setSpanCount(getResources().getInteger(R.integer.span_count0)); — , Sep 30 '16 at 08:41
@Code-Apprentice Here you can find the entire code if you want to take a look. Thank you. Link: https://github.com/calintat/Explorer — , Sep 30 '16 at 08:46
I had this issue before, sorry but i don't remember how i got it solved, buy give `clean & build` a try — Mohammad Ersan, Sep 30 '16 at 09:16
It crashes only on Android 4.x. On 5.x and 6.x it works like a charm and I can't seem to figure out why, it's so damn frustrating. Thanks anyway @MoshErsan. — , Sep 30 '16 at 09:18
@ZackBogdan can you post the whole stacktrace? all stack trace — Mohammad Ersan, Sep 30 '16 at 09:58
if you check this question here http://stackoverflow.com/questions/20680451/inflateexception-binary-xml-file-line-1-error-inflating-class-unknown-cause , you can notice the stacktrace is extended more than yours — Mohammad Ersan, Sep 30 '16 at 10:17
Yeah, unfortunately that's my whole stack. You can see in other thread, that his stack contains some bitmap decoding involved, but that's not the case here. I tried to change the configuration of the project, the compileSdkVersion and minSdkVersion, but nothing works, i can't get it to work on Android 4.X... — , Sep 30 '16 at 10:37

After spending 2 silly days figuring out what was the problem, i figured out the cause. : using attributes as reference to color in xml drawable. On API<21 you can't use attrs to color in xml drawable. So only way is to use reference to color resourse (@color/YOURS_COLOR) or use #RGB format.So if you want to use xml drawable with theme depended colors you should create a drawable for each theme;

Solution: In case someone encounters his exception, you should catch it and have a look at the cause of it in the variables window because that's where the error message is more explicit.

I changed the background for a Relative Layout from @drawable/selectable_background.xml to a different color and everything works fine now.
