When i run my app on my phone(android 6.1 & api 23) it crashes, but when i run it on an emulator(android 7.0 & api 24) it doesn't crash

Question

I have noticed that the app only crashes when I have a backgroundTint on the fab in my main activity.

Here is a screenshot of the error:

here is my main activity:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:backgroundTint="@color/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>

<include layout="@layout/content_main"
    android:id="@+id/include" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:backgroundTint="@color/colorPrimary"
    android:tint="@color/colorWhite"
    app:fabSize="normal"
    app:srcCompat="@android:drawable/ic_input_add"/>

and here is the crash log:

and here is a picture of my build.gradle:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 24
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "xyz.gregswebsite.notes"

        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',  {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    testCompile 'junit:junit:4.12'
}

Which version of com.android.support:appcompat are you using ? — Ashhar Jawaid, Dec 01 '16 at 05:27
Also can you share the mainactivity (java file), and build.gradle file ? — Ashhar Jawaid, Dec 01 '16 at 05:29
try app:backgroundTint="@color/colorPrimary" instead of android:backgroundTint="@color/colorPrimary" — darwin, Dec 01 '16 at 05:30

Ok, based on the answer here, you may need to change the android:backgroundTint to app:backgroundTint. The theme also needs to be AppCompat. It should be working on 22 up, but see if that works.

The answer from Markus on this post seems to solve your issue.

com.android.support:appcompat-v7:21+ added support for tinting widgets on devices running pre android 5.1 (API Level 21). To make use of it make sure you extend or set the AppCompat Theme and use app:backgroundTint instead of android:backgroundTint.

Example:

<android.support.design.widget.FloatingActionButton 
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:src="@drawable/icon"
    app:backgroundTint="@color/accent"
    app:borderWidth="0dp" />

When i run my app on my phone(android 6.1 & api 23) it crashes, but when i run it on an emulator(android 7.0 & api 24) it doesn't crash
