安卓 Logcat 消息 "Could not find Class"

Question

降级后，我现在已将编译 SDK 从 API 23 降级到 API 22，我在 logcat 中收到以下消息。

需要您的帮助以减少错误。 我也用 gradle 应用程序文件更新了这个问题

Gradle 文件如下。我已将编译 sdk 更改为 22，还更改了构建工具编号，还执行了依赖项更改

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    defaultConfig {
        applicationId "com.example.arsal.androtasbih"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:design:22.2.1'
    compile files('C:/Users/Arsal/AndroidStudioProjects/AndroTasbih/apache-httpcomponents-httpcore.jar')
}

每当我更改库或构建级别时，尤其是版本下降时，我总是使缓存无效并重新启动。转到文件 -> 使缓存无效。
