Android vector drawable app:srcCompat not showing images -

i'm using support library show vector images on android kitkat. when test app on emulater don't see of these images. made separate layout android lollipop , above , workd (i think because i'm using src attribute instead of srccompathere's code 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> 

, it's strange because see images on android studio preview window.

original answer

use android.support.v7.widget.appcompatimageview instead of imageview 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 appcompatimageview docs here , appc:srccompat here.

also, make sure following:

setup 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 activity 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 have correct declarations in 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 application class

public class app extends application {    @override public void oncreate() {     super.oncreate();      // make sure use vector drawables     appcompatdelegate.setcompatvectorfromresourcesenabled(true);   } } 

docs: https://developer.android.com/reference/android/support/v7/app/appcompatdelegate.html#setcompatvectorfromresourcesenabled(boolean)
