Android在某些设备上夸大错误导致强制关闭

Question

我正在开发一个Android应用，并且已经在Android 7上对该应用进行了测试，它运行良好。但是最后我决定在较低版本上进行测试，并且感到惊讶。 开始一些活动时，出现很多虚假错误。 这是我的应用gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "x.x.x"
        minSdkVersion 17
        targetSdkVersion 27
        versionCode 0
        versionName "x"
        testInstrumentationRunner  "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    implementation 'com.android.support:design:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.skyfishjy.ripplebackground:library:1.0.1'
    implementation 'com.orhanobut:dialogplus:1.11@aar'
    implementation 'br.com.simplepass:loading-button-android:1.14.0'
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.squareup.picasso:picasso:2.5.2'
    implementation 'com.github.traex.expandablelayout:library:1.3'
    implementation 'com.github.markomilos:paginate:0.5.1'
    implementation 'com.github.castorflex.smoothprogressbar:library:1.1.0'
    implementation 'id.zelory:compressor:2.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.4'
}

这只是一小部分logcat错误：

该项目在android 7上运行良好，但在android 4.2.2和6.0.1上却遇到了这些错误（也许还有其他设备）

Answer 1

您的android:backgroundTint中有一个属性FloatingActionButton，根据View.setBackgroundTintList，它仅在Android API 21及更高版本中可用，这就是为什么您在以下设备上崩溃的原因较低的API级别。要解决向后兼容性问题，请尝试使用app:backgroundTint替换属性：

<android.support.design.widget.FloatingActionButton
    android:id="@+id/newTicketFAB"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|right"
    android:layout_marginBottom="24dp"
    android:layout_marginEnd="16dp"
    android:clickable="true"
    app:backgroundTint="@color/secondry_text"
    app:rippleColor="@color/divider_color"
    app:srcCompat="@drawable/ic_add_black_24dp" />
