Question

当我运行我的应用程序时，我得到了：执行任务：[：app：assembleDebug]

这是gradle控制台：

Executing tasks: [:app:assembleDebug]

Configuration on demand is an incubating feature.
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to C:\Users\JUNZHISHAN Zhu\AppData\Local\Android\Sdk\ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

Incremental java compilation is an incubating feature.

这是我的build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {

        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:26.1.0'

    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == 'com.android.support') {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion '25.3.0'
                }
            }
        }
    }

}

我在Android Studio上运行文件时遇到错误。我只是在Layout和新的JAVA文件中添加一个新的XML文件，试图通过滑动手势来创建一个新的活动。然后发生了错误。昨天该文件运作良好。我是代码和Android工作室的新手。有人可以帮我解决这个问题吗？提前谢谢。

AAPT错误（Facade for 487819257）：libpng错误：不是PNG文件

错误：某些文件崩溃失败，请参阅日志以获取详细信息

PNG 图片格式不正确。

您应该在 build.gradle 部分添加此内容。

android 
{ 
   aaptOptions
   {
   cruncherEnabled = false
   } 
}

然后 Clean-Rebuild-Run 。
