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

一切都在问题中

我有一个带有这个刻度的模块：

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，我得到了100多个关于未找到资源的错误：

例如：

    Error:(9, 21) No resource found that matches the given name: attr 'android:actionModeShareDrawable'.
Error:Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material'.
Error:Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Body1'.

当然，您在API中会遇到这些错误，请检查build.gradle中的compileSdkVersion

例如

如果你保持最新，就不会让你头疼。发生这种情况的原因是，如果为同一个库生成了多个R文件

试试这个

compile'com.android.support:appcompat-v7:19.+'

targetSdkVersion不应该是8，这真的很糟糕。这是一个库模块，我可以使用targetSdkVersion，我想我个人使用md-answer已经很久了。换句话说，我们的minsdk至少应该是API 21吗？不，使用要支持的最小sdk版本。但是，如果您想使用更新SDK中的任何新方法/类/样式（如上所述），请记住，在具有较旧Android版本的设备上（如支持的最旧minSdk）的应用程序可能会抛出

异常

，或者干脆忽略这些行（例如XML文件中的attr）。上面的问题是关于

AppCompat

库的，它为您的应用程序带来了一些来自较新sdk的方法/类/样式，因此新样式（材质，部分）也可能用于较旧的系统（例如ICS），但请注意，它们具有不同的命名，这不会干扰原始名称

    android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
    dexOptions {
        javaMaxHeapSize "2g"
        //jumboMode true
    }
}
