在app:下的build.gradle文件夹中加入如下两行代码：
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
如：
android {
compileSdkVersion 26
buildToolsVersion "25.0.2"
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
defaultConfig {
applicationId "com.bxph.p2p"
minSdkVersion 14
targetSdkVersion 26
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
再次构建，如果还是不行，就试试升级gradle
