使用-库com.android.nfc_extras在实际设备上测试时破坏api 26及以上的AndroidTest。
使用-库com.android.nfc_extras在实际设备上测试时破坏api 26及以上的AndroidTest。
提问于 2018-12-16 21:33:00
我突然发现这份声明：
<uses-library
android:name="com.android.nfc_extras"
android:required="false"/>在我的<application>范围内，AndroidManifest.xml使工具测试失败：
java.lang.NoSuchMethodError: No static method allOf(Lorg/hamcrest/Matcher;Lorg/hamcrest/Matcher;)Lorg/hamcrest/Matcher; in class Lorg/hamcrest/core/AllOf; or its super classes (declaration of 'org.hamcrest.core.AllOf' appears in /system/framework/com.android.nfc_extras.jar)

at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47)
at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17)我现在想出的是：
- 创建了一个演示储存库，以便您能够快速地重现问题；
- 只有带有API 26的真实设备受到影响(例如三星SM-G935F、华为P20 lite)；
- 使用我尝试过的任何API对模拟器进行测试；
- 在实际设备上通过API <26的测试；
- 看起来缺少的类(以及他所有的静态方法)都包含在AndroidTest apk中，但是在运行时，Android试图从com.android.nfc_extras.jar?获取这个类。
- 这种行为可能取决于NFC-功能的手机；
- 对我来说，这看起来不像是MultiDex或混淆问题--演示存储库不是混淆的，也不是单一的。
我想知道，如果有人面临这个问题，为什么会发生这种情况，我如何保持我的AndroidTests工作，并仍然使用这个库？
我的InstrumentedTest.kt文件：
package com.example.abusik.espressotest
import android.support.test.espresso.Espresso.onView
import android.support.test.espresso.action.ViewActions.*
import android.support.test.espresso.assertion.ViewAssertions.matches
import android.support.test.espresso.matcher.ViewMatchers.withId

@RunWith(AndroidJUnit4::class)
@LargeTest
class InstrumentedTest {
private lateinit var stringToBetyped: String
@get:Rule
var activityRule: ActivityTestRule<MainActivity> = ActivityTestRule(MainActivity::class.java)
@Before
fun initValidString() {
// Specify a valid string.
stringToBetyped = "Espresso"
}
@Test
fun changeText_sameActivity() {
// Type text and then press the button.
onView(withId(R.id.et)) //EXCEPTION THROWN HERE
.perform(typeText(stringToBetyped), closeSoftKeyboard())
onView(withId(R.id.btn)).perform(click())
// Check that the text was changed.
onView(withId(R.id.et))
.check(matches(withText(stringToBetyped)))
}

Tests ran to completion.我找到了一个nfc_extras.jar，它似乎不包含对org.hamcrest的任何引用。

无法在运行Android8.0.0的物理MotoX4上复制。
( a) com.android.nfc_extras.jar可能有另一个版本的org.hamcrest.Matcher，而不是测试应用程序--理论上可以在从libs目录加载它时排除它。仿真程序可能不关心，BT和NFC都不可用。
main/Manifest.xml也缺乏NFC权限；添加它可以消除投诉：
<uses-permission android:name="android.permission.NFC" />( b)一个人甚至可以用一个nfc_extras.jar完全摆脱androidTest/Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.abusik.espressotest">
<application>
<uses-library
android:name="com.android.nfc_extras"
android:required="false"
tools:node="remove"/>
</application>
