Points to this being a problem with one of the icons in your NavigationView's menu - specifically, it can't find a resource that it expects to be there. This means that the first thing you should do is make sure that your drawable is not only present in a version specific resource folder (such as drawable-v23).
Secondly, you may be using a VectorDrawable feature not supported on older versions of the platform. You can get consistent behavior by following the Vector drawables backward compatibility solution documentation:
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}

I am guessing that there must be some error in either the XML or the gradle file. I tried changing the appcompat-v7 to various versions but the error still exists.

I think you are using VectorDrawable and you have not implemented it in such a way that it is supported in Kitkat. Just check your nav_header_main layout and if your using a vectorDrawable, check this link on how to support it below lollipop.

App crashes due to android.view.InflateException. Error inflating class

I know this question has been asked a million times, but i get this error only on asus zenfone 2. I feel this may be a memory allocation problem. But I am unable to trace the cause as it does cause the app to crash in other phones with lower os versions.

Most probably the issue is with the XML, and I think it is with the color values you are putting for either textColor, background or other such attributes.
So, you must put your xml code here to identify us the problem.

As showing in your code you are using some custom theme for TextInputLayout i.e #style/TextLabel. Just make sure parent of TextLabel theme is Theme.Design or something like Theme.Design.Light

the problem occurs because of android:theme="#style/TextLabel"
just remove it from code and it's solved
thanks to all

As of December 2019, Google wants you to use com.google.android.material.textfield.TextInputLayout and if you want to set your own theme to a TextInputLayout, make sure you set your custom style as follows:
<style name="CustomTheme" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
<item name="...">...</item>
</style>
Note that FilledBox is the default theme of TextInputLayout. There are multiple themes possible to choose from depending on your needs, the differences are documented here: https://material.io/develop/android/components/text-input-layout/
If you are still using android.support.design.widget.TextInputLayout, this should hopefully work:
<style name="CustomTheme" parent="Widget.Design.TextInputLayout">
<item name="...">...</item>
</style>

Android Use RecyclerView with local recyclerview library instead of loading it from the maven repo

I am trying to use RecyclerView in my project, but because we have some bad proxies, I cannot afford to add compile "com.android.support:recyclerview-v7:+" to my build.gradle because the download is very slow. Instead, for the other libraries, I simply added the .jar files to the 'libs' folder of the project and in build.gradle I have compile files('libs/android-support-v7-recyclerview.jar'). I got the .jar from the Android SDK under /extras/android/support/v7/recyclerview/libs.
I got the android-support-v4 library from the same place and it works fine.
The app is building, but at runtime, I get a NoClassDefFoundError. The behavior can be replicated using Google's RecyclerView sample found in /samples/android-21/ui/views/RecyclerView by replacing in Application/build.gradle these lines:
compile "com.android.support:support-v4:21.+"
compile "com.android.support:gridlayout-v7:21.+"
compile "com.android.support:cardview-v7:21.+"
compile "com.android.support:recyclerview-v7:+"
With these ones:
compile files('libs/android-support-v4.jar')
compile files('libs/android-support-v7-gridlayout.jar')
compile files('libs/android-support-v7-cardview.jar')
compile files('libs/android-support-v7-recyclerview.jar')
And adding the 4 jar files from the same SDK to Application/libs (you need to create the folder as it doesn't have one).
The full error log generated by the Google sample:

I also tried, as people suggested, to use the classes.jar found in extras/android/m2repository/com/android/support/recyclerview-v7/23.3.0/recyclerview-v7-23.3.0.aar but the result was exactly the same.
Any hints on what I might be missing/doing wrong?

The jar file doesn't have all the necessary source code in it. You have to use the aar file instead.
Please check this thread how an aar file can be included in your project.
