当我使用minifyEnabled true
时,我的应用程序崩溃了。我的build.gradle:
apply plugin: 'com.android.application'
android {
signingConfigs {
config {
keyAlias 'myName'
keyPassword 'myPass'
storeFile file('.jks path')
storePassword 'myPass'
}
}
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.user.android.myapp"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.config
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.android.support:support-v4:22.2.1'
}
repositories {
maven {
url 'http://repository.adbuddiz.com/maven'
}
}
我的prguard档案:
-dontwarn com.squareup.okhttp.**
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
logcat输出:

*没有ProGuard,应用程序没有崩溃
