Question

我是android studio的新手。我创建了新的活动，在做了一些更改之后我得到了渲染错误，我在构建gradle时遇到错误，我该如何解决这个问题。

我完成了重建项目并清理了项目但尚未解决我的问题。

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion '22.0.1'

        defaultConfig {
            applicationId "com.example.prakash.aclientzregistration"
            minSdkVersion 14
            targetSdkVersion 23
            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:+'
        compile 'com.android.support:design:22.0.1'
    }

这是我的事件日志错误状态

Answer 1

我认为未安装sdk平台22

试试这个

Goto Tools-＆gt; SDK Manager-＆gt; Android 5.1.1-＆gt; Sdk Platform（22）安装它。

或者尝试像这样改变

    compileSdkVersion 23
    buildToolsVersion '23.0.1'

Answer 2

我认为错误在发布代码中

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

Android Studio gradle构建错误
