我转向了 logback 2.0。当我运行单元测试（使用@Test）时，所有测试都运行良好。然而他们给出了一个错误：

Failed to instantiate [ch.qos.logback.classic.LoggerContext]
Reported exception:

MyApplication 类扩展了 Application 类。它包含以下行：

private static final Logger logger = LoggerFactory.getLogger(MyApplication.class);

我正在使用代码来设置 logback 配置。登录配置是：

public static void configure(Context context, String logFileName) {
    String appInfo = String.format(APP_INFO_PATTERN, AppUtils.getVersionName(context), CommunicationManager.API_VERSION, AppUtils.getAndroidVersion(), Build.MODEL);
    String logPattern = LOG_PATTERN.replace("__app__info__", appInfo).replace("%pid", String.valueOf(android.os.Process.myPid()));
    // since …

I\xe2\x80\x99m 使用 FlurryAnalytics-5.5.0.jar。当我初始化 Flurry 时，我收到一些错误：

FlurryAgent.setLogEnabled(true);\nFlurryAgent.setLogEvents(true);\nFlurryAgent.setLogLevel(android.util.Log.ERROR);\nFlurryAgent.init(this, FLURRY_ID);\n

错误：

找不到类“com.flurry.sdk.br”，从方法引用\n com.flurry.sdk.bq.a

你能给些建议么？

BlockingQueue.put可以抛出InterruptedException.如何通过抛出此异常导致队列中断？

ArrayBlockingQueue<Param> queue = new ArrayBlockingQueue<Param>(NUMBER_OF_MEMBERS);
...
try {
    queue.put(param);
} catch (InterruptedException e) {
    Log.w(TAG, "put Interrupted", e);
}
...
// how can I queue.notify?
