Warning:Exception while processing task java.io.FileNotFoundException: app\build\intermediates\proguard-rules\release\aapt_rules.txt (The system cannot find the path specified)

1. Under 'app' module, in build.gradle file.

buildTypes:

buildTypes {

release {

minifyEnabled true

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

}

Delete blank proguard file. Because I put rules in proguard-rules.pro file, so I delete getDefaultProguardFile('proguard-android.txt'),left only 'proguard-rules.pro'.Just as follows:

buildTypes {

release {

minifyEnabled true

proguardFiles 'proguard-rules.pro'

}

}

2.Delete the folder build in Moudle and rebuild.
