java - 如何将 appcompat-v7 与 android API 19 一起使用

Question

一切都在问题中

我有一个带有这个 gradle 的模块:

apply plugin: 'com.android.library'
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    compileOptions.encoding "ISO-8859-1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:21.0.3'
}

当我将“compileSdkVersion”更改为 19 => 我收到 100 多个关于未找到资源的错误:

示例:

Answer 1

当然你会在 API<21 中遇到这些错误，因为 android:TextAppearance.Material 和其他(Material)是在 API 21 中引入的。AppCompat 正在移植资源，但它们没有使用 android: 前缀(我目前无法检查您是否也在使用这些前缀，但可能是)。如果您使用 API 21 编译您的应用程序并在较低的 API 上运行，设备崩溃也会发生

android: 前缀指的是内置参数，它应该在所有版本的支持的 APIs (minSDK) 中。 API21 之前的系统中不存在 Material
