在Dalvik运行时设备上运行Espresso仪器测试的问题
我遇到类似的问题， FragmentActivity无法通过ActivityInstrumentationTestCase2进行测试
顶级解决方案存在的问题仅适用于使用Eclipse构建系统。 我正在使用Gradle作为我的项目。
在运行ART运行时的Nexus 5上，我的Espresso仪器测试运行完美。 当我在Dalvik运行时或模拟器上使用Nexus 4时，我遇到了在测试框架之外运行应用程序时不会发生的exception。
java.lang.NoClassDefFoundError: com.packagename.fragment.ProgressDialogFragment 在日志中，我发现这些可疑消息类似于链接的问题：
Class resolved by unexpected DEX: Landroid/support/v4/app/DialogFragment2;(0x41e969d8):0x76064000 ref [Landroid/support/v4/app/DialogFragment;] Landroid/support/v4/app/DialogFragment;(0x41e969d8):0x75883000 (Landroid/support/v4/app/DialogFragment2; had used a different Landroid/support/v4/app/DialogFragment; during pre-verification) Unable to resolve superclass of Landroid/support/v4/app/DialogFragment2; (271) Link of class 'Landroid/support/v4/app/DialogFragment2;' failed Unable to resolve superclass of Lcom/packagename/fragment/ProgressDialogFragment; (270) Link of class 'Lcom/packagename/fragment/ProgressDialogFragment;' failed Could not find method com.packagename.fragment.ProgressDialogFragment.newInstance, referenced from method com.packagename.activity.IntroActivity.doJoin VFY: unable to resolve static method 47365: Lcom/packagename/fragment/ProgressDialogFragment;.newInstance (I)Landroid/support/v4/app/DialogFragment2; VFY: replacing opcode 0x71 at 0x0063
ProgressDialogFragment是DialogFragment2的子类，它是Android支持库的DialogFragment类的DialogFragment类。
以下是我的Gradle文件中的依赖项，如果这有帮助：
compile 'com.android.support:support-v4:+' compile 'com.android.support:appcompat-v7:+' compile 'com.google.android.gms:play-services:+' compile 'com.google.code.findbugs:jsr305:+' compile 'com.fasterxml.jackson.core:jackson-databind:2.3.+' compile 'de.greenrobot:greendao:1.3.+' compile 'fr.avianey:facebook-android-api:+@aar' compile 'com.squareup.mimecraft:mimecraft:1.1.+' compile 'com.squareup.picasso:picasso:2.2.+' compile 'com.squareup.okhttp:okhttp:1.5.+' compile 'eu.inmite.android.lib:android-styled-dialogs:1.1.+@aar' compile 'com.newrelic.agent.android:android-agent:3.+' compile 'uk.co.chrisjenx:calligraphy:0.7.+' compile 'com.github.chrisbanes.actionbarpulltorefresh:library:0.9.+' compile 'com.github.chrisbanes.actionbarpulltorefresh:extra-abc:0.9.+' apt "com.jakewharton:butterknife:${project.ext.butterKnifeVersion}" compile "com.jakewharton:butterknife:${project.ext.butterKnifeVersion}" compile fileTree(dir: 'libs', include: '*.jar') // Excluded modules were determined from here: https://github.com/robolectric/deckard-gradle instrumentTestCompile fileTree(dir: 'libs-test', include: '*.jar') instrumentTestCompile 'com.google.guava:guava:14.0.1', 'com.squareup.dagger:dagger:1.1.0', 'org.hamcrest:hamcrest-integration:1.1', 'org.hamcrest:hamcrest-core:1.1', 'org.hamcrest:hamcrest-library:1.1' instrumentTestCompile('junit:junit:4.11') { exclude module: 'hamcrest-core' } instrumentTestCompile('org.robolectric:robolectric:2.3-SNAPSHOT') { exclude module: 'classworlds' exclude module: 'maven-artifact' exclude module: 'maven-artifact-manager' exclude module: 'maven-error-diagnostics' exclude module: 'maven-model' exclude module: 'maven-plugin-registry' exclude module: 'maven-profile' exclude module: 'maven-project' exclude module: 'maven-settings' exclude module: 'nekohtml' exclude module: 'plexus-container-default' exclude module: 'plexus-interpolation' exclude module: 'plexus-utils' exclude module: 'wagon-file' exclude module: 'wagon-http-lightweight' exclude module: 'wagon-http-shared' exclude module: 'wagon-provider-api' } instrumentTestCompile 'org.mockito:mockito-core:1.9.+'
所以我的问题是如何确保在应用程序APK和测试APK之间使用相同的支持库？ 我已经尝试在instrumentTestCompile 'com.android.support:support-v4:+' support- instrumentTestCompile 'com.android.support:support-v4:+'添加以确保相同的支持库版本，但这没有帮助。
经过多次痛苦，汗水和眼泪。 我设法确定了解决方案。 只需将exclude group: 'com.android.support', module: 'support-v4'到Robolectric的排除列表中，允许Robolectric继续工作，同时让它不会在Dalvik运行时崩溃。
