哪个软件包适合MultiDexTestRunner?android.support.multidex或com.android.test.runner

问题描述

页面 http://developer.android.com/tools/building/multidex.html#testing 建议

   dependencies {
     compile 'com.android.support:multidex:1.0.1'
     androidTestCompile 'com.android.support:multidex-instrumentation:1.0.1'
   }
   android {
     defaultConfig {
        multiDexEnabled true
        testInstrumentationRunner "android.support.multidex.MultiDexTestRunner"
     }
  }

但是在运行测试时会产生ClassNotFoundException.

But that produces a ClassNotFoundException when the tests are run.

API文档和dexdump显示存在com.android.test.runner.MultiDexTestRunner.

The API documentation and dexdump show that there is com.android.test.runner.MultiDexTestRunner.

因此，如果我不相信文档，而是指定

So if I disbelieve the documentation and instead specify

   dependencies {
     compile 'com.android.support:multidex:1.0.1'
     androidTestCompile 'com.android.support:multidex-instrumentation:1.0.1'
   }
  android {
     defaultConfig {
        multiDexEnabled true
        testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
     }
   }

然后我得到

com/company/myapp/MyApp; had used a different Landroid/support/multidex/MultiDexApplication; during pre-verification
...
IllegalAccessExceptionIllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

我怀疑文档页面是错误的，正确的路径是com.android.test.runner.MultiDexTestRunner ...另外我还有其他问题.

I suspect that the doc page is wrong and the correct path is com.android.test.runner.MultiDexTestRunner ... plus I have some other issue.

请注意，multidex应用程序运行良好.不知何故，第二个MultiDexApplication已包含在测试apk中.

Note the multidex application works fine. Somehow a second MultiDexApplication is included in the test apk.

问题:
哪个是MultiDexTestRunner的正确路径?为什么我在测试apk中得到第二个MultiDexApplication?

Questions:
Which is the correct path for MultiDexTestRunner?Why am I getting a second MultiDexApplication in the test apk?

推荐答案

更新:这是解决方法.这是一种常见的模式，当您看到这样的错误消息使用了不同的L< package>时；在预验证期间，您需要在运行测试时排除软件包.

UPDATE: here's the fix. That's a common pattern, when you see such error message had used a different L<package>; during pre-verification, you need to exclude the package when running the test.

build.gradle

android {
    // ...
    defaultConfig {
        // ...
        multiDexEnabled true
        testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
    }
}

dependencies {
    // ...
    // Need to exclude this when running test
    androidTestCompile('com.android.support:multidex-instrumentation:1.0.1') {
        exclude group: 'com.android.support', module: 'multidex'
    }
}

Application.java

public class Application extends android.app.Application {
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}
