Question

所有都在问题中

我有一个带有此渐变的模块：

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'
}

当我改变＆＃34; compileSdkVersion＆＃34;到19 =＆gt;我发现100多个关于未找到的资源的错误：

示例：

Answer 1

当然，您在API＆lt; 21中收到这些错误，因为在API 21中引入了android:TextAppearance.Material和其他（Material）.AppCompat正在移植资源，但它们没有使用android:前缀（I如果这些你也在使用，那么此时无法检查，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。材料不存在于API21之前的系统中

Answer 2

检查build.gradle中的compileSdkVersion

例如。

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

如果你保持最新，不应该让你头痛。发生这种情况的原因是，为同一个库生成了多个R文件。
