【问题描述】：

尝试在手机上运行我的 android 应用程序时意外收到以下错误。本质上，在应用程序中，它调用 messageservice 以便我能够运行即时消息。我正在使用 Sinch for android 来处理我的即时消息。

以下是日志猫消息：

下面是 MessageService 活动：

        if (currentUserId != null && !isSinchClientStarted()) {
            startSinchClient(currentUserId);
        }

        broadcaster = LocalBroadcastManager.getInstance(this);

        return super.onStartCommand(intent, flags, startId);
    }

    public void startSinchClient(String username) {
        sinchClient = Sinch.getSinchClientBuilder().context(this).userId(username).applicationKey(APP_KEY)
                .applicationSecret(APP_SECRET).environmentHost(ENVIRONMENT).build();

        sinchClient.addSinchClientListener(this);

        sinchClient.setSupportMessaging(true);
        sinchClient.setSupportActiveConnectionInBackground(true);

        sinchClient.checkManifest();

        broadcastIntent.putExtra("success", false);
        broadcaster.sendBroadcast(broadcastIntent);

        sinchClient = null;
    }

    @Override

    }

    @Override
    public void onRegistrationCredentialsRequired(SinchClient client, ClientRegistration clientRegistration) {
    }

    public void sendMessage(String recipientUserId, String textBody) {
        if (messageClient != null) {
            WritableMessage message = new WritableMessage(recipientUserId, textBody);
            messageClient.send(message);
        }
    }

    public void addMessageClientListener(MessageClientListener listener) {
        if (messageClient != null) {
            messageClient.addMessageClientListener(listener);
        }
    }

        }
    }

    @Override

            MessageService.this.sendMessage(recipientUserId, textBody);
        }

        }

        public boolean isSinchClientStarted() {
            return MessageService.this.isSinchClientStarted();
        }
    }
}

任何帮助将不胜感激。

【问题讨论】：

你的库有问题，你的应用看不到你的.so，我想
你会建议我重新下载 sinch 库吗？或者你有什么其他的建议？
不，请尝试查找设置 sinch 库的说明，确保您没有遗漏某些部分。对不起，我不熟悉 android studio。
谢谢。虽然我没有使用 android studio，但是 eclipse，这可能是问题的核心

标签： java android android-layout android-activity service

【解决方案1】：

您需要将 sinch 库复制到您的项目中，请参阅sinch client for android documentation

下载the sinch android sdk zip，将libs文件夹的内容复制到项目根目录下的libs。

清理并重建项目。在测试 apk 之前，请以 zip 格式打开 apk，并确保 .so 文件位于 lib\*\ 文件夹中；

如果您无法让 eclipse 正确打包应用程序，please consider using sinch's documentation and use android studio as they suggest

【讨论】：

在Tools -> Andoird -> SDK Manager或键盘快捷键ctrl + shift + a下，输入sdk manager，点击。
试试这个示例github.com/sinch/android-messaging-tutorial-skeleton 来熟悉 AS 和 sinch
你能显示jar tvf <your apk>的输出吗，这只会显示你的apk中的文件列表。
打开命令提示符，cd 到您的 apk 所在的目录，输入 jar tfv apk_file_name，在此处发布屏幕截图图像或将您看到的输出复制粘贴到此处。
您的 apk zip 屏幕不显示 libs 文件夹！我们需要解决这个问题；右键单击 eclipse -> properties -> java build path -> libraries 中的项目，在此处手动添加您的 libs 文件夹。然后，单击同一屏幕中的Order and Export。如果未选中，请选择您刚刚添加的libs。然后，点击Project -> Clean，重建，再次用zip打开apk，看看libs文件夹是否出现。
