我正在运行Android Studio 0.5.1.我已经下载了Crashlytics Android Studio插件并从光盘安装了它.当我重新启动Android Studio时,我收到以下异常

Plugin 'com.crashlytics.tools.androidstudio' failed to initialize and will be disabled.  Please restart Android Studio.

我编写了一个简单的测试用例类,并将其放在Android Studio的默认测试目录中:"src/androidTest".我创建了一个Android Tests构建配置,用于查找模块中的所有测试.当我运行构建配置时,我的测试没有执行,我在logcat中收到以下消息:W/TestGrouping? Invalid Package: '' could not be found or has no tests.如果我指定测试包甚至特定的测试类,我会得到类似的类未找到的消息.

我的测试类如下:

public class FirstTest extends InstrumentationTestCase {

public void testSample() {
        final int expected = 1;
        final int reality = 5;
        assertEquals(expected, reality);
    }
}

我的build.gradle文件如下所示:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:gridlayout-v7:19.0.1'
    compile 'com.android.support:support-v4:19.0.1' …
