我正在使用 Robolectric 3 rc2 与OkHttp Mock WebServer和Google Play服务。
我需要测试json的解析以及使用模拟服务器和服务器客户端已经使用的相关处理。整个服务器客户端调用在后台中运行，并带有 okhttp异步调用。整个项目如果是图书馆项目。
完整代码 here
Gradle配置：
testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'
testCompile ("org.robolectric:robolectric:3.0-rc2"){
exclude module: 'commons-logging'
exclude module: 'httpclient'
}
testCompile 'com.google.android.gms:play-services:7.0.0'
testCompile ("org.robolectric:shadows-play-services:3.0-rc2"){
exclude module: 'commons-logging'
exclude module: 'httpclient'
}
testCompile 'org.robolectric:shadows-support-v4:3.0-rc2'
testCompile 'org.assertj:assertj-core:1.7.0'
testCompile 'com.squareup.okhttp:mockwebserver:1.2.1'
我正在运行测试为什么命令行：
./ gradlew mymodule：clean mymodule：assembleDebug mymodule：testDebug --info
我收到与Google Play服务相关的错误 java.lang.IllegalStateException: Calling this from your main thread can lead to deadlock
当gettign AdvertisingId ......我肯定做错了什么......
完成堆栈跟踪：

答案 0 :(得分：-1)
java.lang.RuntimeException: java.lang.IllegalStateException: Calling this from your main thread can lead to deadlock
来自异常的消息明确描述了您所做的错误。显然你不应该在UI线程上调用AdvertisingIdClient，因为库不允许它（原因如上所述。它可能导致死锁）。
因此，您必须使用 AsyncTask 或任何其他后台任务库才能调用此API。
AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... params) {
AdvertisingIdClient.Info idInfo;
String advertId = null;
try {
idInfo = AdvertisingIdClient.getAdvertisingIdInfo(context);
advertId = idInfo.getId();
} catch (GooglePlayServicesNotAvailableException|GooglePlayServicesRepairableException|IOException e) {
e.printStackTrace();
}
return advertId;
}
@Override
protected void onPostExecute(final String advertId) {
KakaoTaskQueue.getInstance().addTask(new KakaoResultTask<EventsLogResponse>(callback) {
@Override
public EventsLogResponse call() throws Exception {
if (advertId == null)
throw new IllegalAccessException("Could not get adid from the device.");
rootEvent.setFrom(advertId);
return EventsApi.requestLoggingEvents(rootEvent, leafEvents);
}
});
}
};
task.execute();
这是您使用 AsyncTask 在 AdvertisingIdClient 类中调用 getAdvertisingIdInfo 方法的方法。如果您有任何其他问题，请评论：）
