java - 导入模块库后 Gradle 错误

Question

这是我从错误消息中得到的:

Information:Gradle tasks [clean, :app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :library:generateDebugSources, :library:generateDebugAndroidTestSources, :library:mockableAndroidJar, :library:prepareDebugUnitTestDependencies] Error:Some file crunching failed, see logs for details Error:Execution failed for task ':app:mergeDebugResources'.> Error: Some file crunching failed, see logs for details Information:BUILD FAILED Information:Total time: 3.008 secs Information:2 errors Information:0 warnings Information:See complete output in console

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Parallel execution with configuration on demand is an incubating feature.
Using the 'clean' task in combination with parallel execution may lead to unexpected runtime behavior.
Incremental java compilation is an incubating feature.

如何解决？

Answer 1

检查捆绑的可绘制资源/图像。其中之一或少数可能不是正确的 .png 文件

AAPT: libpng error: Not a PNG file

解决方案在编辑器中打开不正确的文件，并以相同的名称和正确的 .png 扩展名保存。
