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？
答案 0 :(得分：0)
您应该在gradle.properties中发表评论org.gradle.parallel = true。
答案 1 :(得分：0)
检查捆绑的可绘制资源/图像。其中一个或少数可能不是正确的.png文件
AAPT：libpng错误：不是PNG文件
解决方案在编辑器中打开不正确的文件，并使用相同的名称和正确的.png扩展名保存。
