Error:Application and test application id cannot be the same: both are 'cn.deu.bztc.happyidiom.activ

Error:Application and test application id cannot be the same: both are 'cn.deu.bztc.happyidiom.activity' for debugAndroidTest

解决办法：

defaultConfig {
applicationId "xx.xx.xxx"
minSdkVersion 17
targetSdkVersion 23

testApplicationId "xx.xx.xxx"
testInstrumentationRunner "android.test.InstrumentationTestRunner"
}

testApplicationId "xx.xx.xxx"
testInstrumentationRunner "android.test.InstrumentationTestRunner"
}

把这个删除就Ok了 很简单的

testApplicationId "xx.xx.xxx"
testInstrumentationRunner "android.test.InstrumentationTestRunner"
}
