android - 当我在手机(android 6.1 和 api 23)上运行我的应用程序时它崩溃了，但是当我在模拟器(android 7.0 和 api 24)上运行它时它不会崩溃

Question

我注意到只有在我的主要 Activity 中 fab 上有 backgroundTint 时，应用程序才会崩溃。

错误截图如下:

这是我的主要 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"/>

这是崩溃日志:

这是我的 build.gradle 的图片:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 24
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "xyz.gregswebsite.notes"
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        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'
}

好的，基于答案here ，您可能需要将 android:backgroundTint 更改为 app:backgroundTint。主题也需要是 AppCompat。它应该在 22 up 上工作，但看看它是否有效。
