未找到抽屉布局类错误

Question

我将minSDKVersion从19更新为21.当我尝试运行我的应用程序时，它现在崩溃了。我得到“Java.lang.ClassNotFoundException：Didnt find class android.support.v4.widget.DrawerLayout”任何想法如何解决这个问题？

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.id"
        minSdkVersion 21
        targetSdkVersion 21
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

repositories {

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:support-v4:19.1.0'


}

您已通过项目更改更新了您的sdk：import android.support.v7.app.ActionBarDrawerToggle;删除import android.support.v4.app.ActionBarDrawerToggle;
