问题
I'm not very experienced with Espresso, but I finally succeed to run it.
I have an app that need to be shrink by Proguard in order to be under the 56K methods.
The app starts with a 3 sec animation, so I need to wait until this animation is over in order to continue. This is what I tried to do with the method waitFor(long delay)
I tried to put this method as a standalone class, inner class and even project class = same error.
Here is the Proguard file:
android {
...
compileSdkVersion ANDROID_BUILD_SDK_VERSION
buildToolsVersion ANDROID_BUILD_TOOLS_VERSION
productFlavors {
// Define separate dev and prod product flavors.
dev {
// dev utilizes minSDKVersion = 21 to allow the Android gradle plugin
// to pre-dex each module and produce an APK that can be tested on
// Android Lollipop without time consuming dex merging processes.
minSdkVersion 21
}
prod {
// The actual minSdkVersion for the application.
minSdkVersion ANDROID_BUILD_MIN_SDK_VERSION
}
}
defaultConfig {
applicationId "fr.xs.app.y"
targetSdkVersion ANDROID_BUILD_TARGET_SDK_VERSION
minSdkVersion ANDROID_BUILD_MIN_SDK_VERSION
versionCode ANDROID_BUILD_VERSION_CODE
versionName ANDROID_BUILD_APP_VERSION_NAME
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
// point sur le build de test
testBuildType = "validation"
buildTypes {
release {
debuggable false
ext.enableCrashlytics = true
renderscriptOptimLevel 3
signingConfig android.signingConfigs.release
zipAlignEnabled true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules-release.pro'
}
debug {

renderscriptOptimLevel 3
applicationIdSuffix ".debug"
versionNameSuffix "debug"
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-debug.pro', 'proguard-rules-dontobfuscate.pro'
}
validation.initWith(debug)
validation {
debuggable false
renderscriptOptimLevel 3
applicationIdSuffix ".validation"
versionNameSuffix "validation"
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-debug.pro', 'proguard-rules-dontobfuscate.pro'
testProguardFile('proguard-rules-test.pro')
}
}
...
}
Proguard Configuration
The following in is both Proguard files (debug and test) -keep class fr.xs.app.y.** { *; } -dontobfuscate
I checked that this class is in the mapping.txt (build/output/mapping/androidTest/dev) and not transformed to another string.
