我找到了一个类似的 qnestion和答案，

-从构建路径中删除所有 Android 库项目和外部 jar。

-在您的项目中创建一个名为“libs”的文件夹。

-将所有外部 .jars 放在该文件夹中，ADT 现在应该将它们放在“Android Dependencies”下。

- 以正常方式重新导入所有以前的 Android 库项目。

但这对我不起作用。

这是 Manifestfile，如果我删除应用程序名称，应用程序运行正常。但我需要它才能启用推送通知..

安卓 list .xml

                // even though we call takeoff push notifications are disabled by default
                // you have to explicitly turn them on like so
                PushManager.enablePush();

                // let the push manager know about our intent receiver
                PushManager.shared().setIntentReceiver(IntentReceiver.class); 
                // name must match broadcast receiver from step 7

                // set some preferences for sounds and vibration
                PushPreferences prefs = PushManager.shared().getPreferences();
                prefs.setSoundEnabled(true);
                prefs.setVibrateEnabled(true);

                // apid is a unique identifier for a particular device

                Logger.info("My Application onCreate - App APID: " + lPushId);

    }
}

如果您在运行时遇到 NoClassDefFoundError，那么我怀疑您没有将它们包含在运行时工作中。您必须像这样检查每个 .jar 的复选框:
