I am using Android Studio 1.2.2 and tried to generate APK with proguard setting. But I can't do it and got below error message.
"Execution failed for task ':packageRelease'.
Unable to compute hash of /Users/Documents/projectX/app/build/intermediates/classes-proguard/release/classes.jar "
The proguard setting is just simple.
-dontshrink
-dontoptimize
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
And the gradle file is below.
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion "Google Inc.:Google APIs:22"
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.bientus.cirque.sansotong"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
// multiDexEnabled true
}
buildTypes {
debug {
debuggable true
}
release {
minifyEnabled true
//proguardFiles 'proguard-project.txt', 'proguard.cfg'
//proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt', 'proguard.cfg'
proguardFiles 'proguard-project.txt'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile "com.google.android.gms:play-services:7.5.0"
// compile 'com.android.support:multidex:1.0.0'
}
buildscript {
repositories {
// mavenCentral()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
classpath 'com.google.gms:google-services:1.3.0-beta1'
}
}
Can anybody give any idea or thought? Thank you very much!
Just add to the project's proguard-rules:
-keep public class com.google.android.gms.**
-dontwarn com.google.android.gms.**
