android studio 编译问题汇总

1，Timed out while waiting for slave aapt process, try setting environment variable SLAVE_AAPT_TIMEOUT to a value bigger than 5 seconds

把一个32位机器下的项目导入到64位android studio中运行时报这个错，进程里面出现很多aapt.exe，原来的app/build.gradle中用的buildTools版本是22.0.1

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2" //改这里
    compileOptions.encoding = "GBK"
    ...
        }
    }
}

2  Android studio 解决libpng warning: iCCP: Not recognizing known sRGB profile that has been edited

将

buildToolsVersion "22.0.1"

 改为

buildToolsVersion "20.0.0"
