如何使用appcompat-v7与android API 19

An-*_*oid 3 java compatibility android android-appcompat android-5.0-lollipop

一切都在质疑

我有一个这个模块的模块:

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 =>时,我发现100多个关于未找到的资源的错误:

示例:

当然,你在API <21中遇到这些错误,因为android:TextAppearance.Material其他(材料)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(如果你使用的话,我现在也无法检查) ,但可能是的).如果您使用API​​ 21编译应用程序并在较低的API设备上运行,则也会发生崩溃

android:前缀是指内置参数,它应该在支持的API的所有版本(minSDK)中.API21之前的系统中不存在材料
