我遇到了Robolectric在我的

AndroidManifest.xml中遇到麻烦的问题.我的应用程序运行正常,但Robolectric正在失败所有的测试,甚至assertTrue(true).错误是：

android.view.InflateException: XML file /[blah]/build/res/all/debug/layout/activity_main.xml line #-1 (sorry, not yet implemented): Error inflating class fragment

造成：

java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 4030500 but found 0. You must have the following declaration within the element:

问题是我已经在我的清单中有这一行.以下是一些相关文件：

AndroidManifest.xml中：

package="com.bryansills.studywithfriends"

android:versionCode="1"

android:versionName="1.0">

android:minSdkVersion="14"

android:targetSdkVersion="18"/>

android:glEsVersion="0x00020000"

android:required="true"/>

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:logo="@drawable/ic_action_icon"

android:label="@string/app_name"

android:theme="@style/study">

android:name="com.bryansills.studywithfriends.MainActivity"

android:label="@string/app_name">

android:name="com.google.android.maps.v2.API_KEY"

android:value="@string/google_maps_api_key_v2"/>

android:name="com.google.android.gms.version"

android:value="@integer/google_play_services_version"/>
