我已将一些格式为 *.png 的图片添加到我的可绘制目录中，并将其与布局相关联。但是每次我尝试构建它时，都会出现错误

"...Crunching Crunsher ...png failed"

以下是控制台的输出:

我尝试清理项目，重建它，通过“gradlew clean build --refresh-dependencies”刷新依赖项，但没有任何效果。我已经检查了 build.gradle 文件中的依赖关系，但似乎没有任何东西产生错误。

   apply plugin: 'com.android.application'
   android {
   compileSdkVersion 22
   buildToolsVersion "22.0.1"
   compileOptions.encoding = 'windows-1251'

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

   dependencies {
   compile 'com.android.support:support-v4:22.2.0'
  }

您有什么想法，错误的根源是什么？文件路径也不会太长，每次都低于 256 个标志，这也不是问题:/

提前谢谢你:)

最佳答案

在我的情况下，错误是由我添加到可绘制文件夹的 PNG 文件引起的。我通过更改文本(以不正确的方式)将其扩展名从 jpg 更改为 png，然后将其上传为 PNG。

这就是 Android Studio 所指出的问题。

我解决了这个问题，并通过使用 Paint.NET 更改文件扩展名使错误消失工具或任何其他工具(正确方式)，然后将其上传到可绘制文件夹。
