Android vector drawable app:srcCompat not showing images

I'm using support library to show vector images on android kitkat. When I test my app on emulater I don't see any of these images. I made a separate layout for android lollipop and above and it workd perfectly (I think because I'm using src attribute instead of srcCompatHere's the code where I'm usign support library

<LinearLayout android:layout_alignParentBottom="true"
android:id="@+id/lake_detail"
android:background="@drawable/my_fishing_plan_footer_line"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="90dp"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<RelativeLayout
            android:layout_marginRight="3dp"
            android:id="@+id/fire_logo"
            android:layout_width="20sp"
            android:layout_height="20sp">

            <ImageView
                android:tint="#d74313"
                app:srcCompat="@drawable/circle_icon"
                android:layout_width="30sp"
                android:layout_height="30sp" />

            <ImageView
                android:layout_centerVertical="true"
                android:layout_centerHorizontal="true"
                app:srcCompat="@drawable/lauzaviete"
                android:layout_width="25dp"
                android:layout_height="25dp" />

        </RelativeLayout>

and it's strange because I see the images on android studio preview window.

Original Answer

Use android.support.v7.widget.AppCompatImageView instead of ImageView in your layout, like this:

<LinearLayout 
  ...
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto">

  <android.support.v7.widget.AppCompatImageView
    android:tint="#d74313"
    app:srcCompat="@drawable/circle_icon"
    android:layout_width="30sp"
    android:layout_height="30sp" />
    
  <android.support.v7.widget.AppCompatImageView
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    app:srcCompat="@drawable/lauzaviete"
    android:layout_width="25dp"
    android:layout_height="25dp" />
</LinearLayout>

See the AppCompatImageView docs here and app:srcCompat here.

Also, make sure to do the following:

Setup your build.gradle

android {
  defaultConfig {
    vectorDrawables {
      useSupportLibrary = true
    }
  }
}

Docs: https://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.VectorDrawablesOptions.html#com.android.build.gradle.internal.dsl.VectorDrawablesOptions:useSupportLibrary

Extend your Activity with AppCompatActivity

public final class MainActivity extends AppCompatActivity {    
  @Override protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
  }
}

When using app:srcCompat, make sure to have the correct declarations in your layout:

<LinearLayout 
  ...
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto">
  ...
</LinearLayout>

Optional (warning: please read docs): setCompatVectorFromResourcesEnabled in your Application class

public class App extends Application {

  @Override public void onCreate() {
    super.onCreate();

    // Make sure we use vector drawables
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
  }
}

Docs: https://developer.android.com/reference/android/support/v7/app/AppCompatDelegate.html#setCompatVectorFromResourcesEnabled(boolean)

I had a similar issue and after following all steps from Jared Burrows's answer the problem was not solved.

Turns out that the "app" namespace inside my layout file was set as:

xmlns:app="http://schemas.android.com/tools"

instead of:

xmlns:app="http://schemas.android.com/apk/res-auto"

After changing this the problem was fixed

Incase anyone else runs into this problem and is using androidx, then try using androidx.appcompat.widget.AppCompatImageView

In summary:

1. Put vector drawable support in your module (build.gradle)

   defaultConfig {           
        vectorDrawables.useSupportLibrary = true
    }
   

2. Instead of android:src="@drawable/icon" use app:srcCompat="@drawable/icon"

3. Make sure your Activity extends AppCompatActivity without this step is not possible to show vector image with app:srcCompat

use:

android:background="@drawable/circle_icon"

instead of:

app:srcCompat="@drawable/circle_icon"

Implement and app:srcCompact and then you can use it on the ImageView

implementation 'com.android.support:appcompat-v7:28.0.0'

Make sure you implement the right version.

Then in your build.gradle set android.defaultConfig.vectorDrawables.useSupportLibrary = true

defaultConfig {

    //...

    vectorDrawables {
        useSupportLibrary true
    }
}

The problem was with my Code as well. Solution: As Android is upgrading to Androidx Artifacts, I used Instead of Regular and it Worked!

Additional be sure that your vector drawables located in drawable and not in drawable-anydpi.

I end up often with problems if the graphics located in drawable-anydpi folder.
