Question

我的应用在我的手机上完美运行。在一些旧设备上，它崩溃了：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.blub.bla/com.blub.bla.MainActivity}: android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class ImageButton

我检查了其他帖子，大部分时间都与gradle有关，我可以说我已设置vectorDrawables.useSupportLibrary = true。

Gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27


    repositories {
        mavenCentral()
    }
    defaultConfig {
        applicationId "com.blub.bla"
        vectorDrawables.useSupportLibrary = true
        minSdkVersion 19
        targetSdkVersion 27

        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    android {
        lintOptions {
            disable 'RestrictedApi'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.facebook.android:facebook-login:[4,5)'
    implementation 'com.facebook.android:facebook-share:[4,5)'
    implementation 'com.android.support:appcompat-v7:27.0.1'
    implementation 'com.android.support:design:27.0.1'

    implementation 'com.squareup.picasso:picasso:2.5.2'
    implementation 'com.squareup.okhttp:okhttp:2.4.0'
    implementation 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'

    implementation 'com.google.android.gms:play-services-places:10.+'

    implementation 'eu.the4thfloor.volley:com.android.volley:2015.05.28'
    testImplementation 'junit:junit:4.12'
}

修改： activity_main.xml中

有谁知道如何解决这个问题？：（

Answer 1

在24 API之前，您无法在矢量绘图中使用渐变。

关于android:fillColor，例如，来自https://developer.android.com/reference/android/graphics/drawable/VectorDrawable.html：

指定用于填充路径的颜色。可以是颜色，或者对于SDK 24+，颜色状态列表或渐变颜色

Answer 2

第一个问题：我在drawable/v21而不是drawable中有一些资源（不容易看到，因为它在Android工作室中显示相同的文件夹，只需在文件名旁边加(21)

第二个问题：使用app:srcCompat代替android:background或android:res

Answer 3

当您尝试在21岁以下的Android版本中显示SVG时，您可以使用AppCompatImageButton而不是ImageButton或AppCompatImageView与app：srcCompat
