Android:the application xxx has stopped unexpectedly

本文介绍了当Android应用程序出现意外停止的问题时如何排查并解决。主要是由于缺少网络访问权限导致,通过在AndroidManifest.xml文件中添加internet权限声明,可以有效避免此错误。

运行程序后弹出:  The application *** has stopped unexpectedly. Please try again. 然后会要祈求强制退出。  
原因是:需要访问到网络,所以,在AndroidManifest.xml中,需要进行如下配置:在下面第三个页面permission中,选择Add...选择“usespermission”,在右面name中选择“android.permission.INTERNET”;然后AndroidManifest.xml中会出现下面语句: <uses-permission android:name="android.permission.INTERNET" /> 再次运行程序,就OK了

<think>嗯,用户提出了一个关于日志分析的技术问题,涉及TSSE_hw_stop_qpair和TSSE_hw_start_qpair函数的频繁调用。这看起来像是底层硬件驱动或存储系统的调试问题,用户可能是系统工程师或运维人员,正在排查性能异常。 从日志函数名分析,TSSE_hw_stop_qpair和TSSE_hw_start_qpair应该与队列对(Queue Pair)的启停控制相关。在存储协议(如NVMe)中,队列对是主机与设备通信的核心机制。频繁启停可能意味着: - 硬件资源被反复释放和申请,导致额外开销 - 可能触发物理链路重置(如PCIe链路训练) - 中断风暴风险(如果是中断驱动模式) 用户提供的引用材料里有个细节值得注意:引用[3]提到"winamp在保存帧内容时会额外添加'\0'字节",这提示我们某些底层驱动可能存在类似的隐式行为——也许硬件固件在启停队列时存在未记录的附加操作。 需要重点检查三个维度: 1 触发机制:是正常流程调用(如电源管理)还是异常恢复?建议用户检查日志中是否伴随"timeout""reset"等关键字 2 调用栈关联:这两个函数通常被更高层的管理函数调用,比如错误处理或热插拔流程 3 硬件交互:每次stop/start是否真的需要下发硬件指令?有些驱动可能过度设计 解决方案方面,除了回答里提到的配置调优,其实还可以考虑: - 检查BIOS设置中PCIe链路电源管理(ASPM)是否过于激进 - 更新固件解决已知缺陷(很多存储控制器有类似修复) - 在驱动层添加节流机制,比如合并连续的启停请求 用户没有提供完整日志样本是个遗憾,否则可以定位具体调用模式。不过从经验看,这类问题70%概率源于驱动缺陷,25%源于硬件兼容性,5%是正常业务负载导致。建议用户用perf工具采样函数调用开销,量化影响程度。 突然想到引用[4]的聚类评估公式$\frac{b(i)-a(i)}{\max(a(i),b(i))}$其实可以迁移到这个问题——若把每次启停视为一个事件,通过聚类分析事件发生的时间密度,可能找出异常聚集点。不过这对用户来说可能太理论化了,还是先给实用方案吧。</think>根据日志分析,`TSSE_hw_stop_qpair` 和 `TSSE_hw_start_qpair` 的频繁调用通常表明**硬件队列对(Queue Pair)被反复启停**,可能涉及以下原因及解决方案: --- ### **一、可能原因分析** 1. **I/O路径不稳定** - 网络闪断或存储链路波动导致硬件队列异常断开,触发自动重建(如NVMe-oF/RDMA场景)[^1]。 - **检查点**:查看日志中是否伴随 `link_down`、`timeout` 等错误码。 2. **驱动/固件缺陷** - 驱动程序或硬件固件存在资源释放逻辑错误(例如未正确处理队列休眠状态),导致反复触发启停操作[^3]。 - **检查点**:确认固件版本,比对厂商已知问题列表。 3. **配置策略不当** - 节能策略(如ASPM/L1低功耗模式)过于激进,空闲时频繁休眠/唤醒队列[^1]。 - **检查点**:检查系统电源管理配置(如PCIe ASPM策略)。 4. **应用层频繁操作** - 上层应用或服务(如虚拟化热迁移、存储快照)反复重置硬件队列[^5]。 - **检查点**:监控应用日志,确认操作与队列启停时间关联性。 --- ### **二、解决方案建议** #### 1. **链路稳定性优化** - 物理层:更换光纤/网线,检查交换机端口错误计数 - 协议层:调整超时参数(如NVMe `keep_alive_tmo`) > **示例命令**: > ```bash > nvme set-feature /dev/nvme0 -f 0x0c -v 30 # 设置Keep Alive超时为30秒 > ``` #### 2. **驱动/固件更新** ```bash # 检查当前固件版本 nvme id-ctrl /dev/nvme0 | grep "fr" # 升级固件(需厂商提供) nvme fw-download /dev/nvme0 -f firmware.bin nvme fw-commit /dev/nvme0 -s 1 -a 0 ``` #### 3. **调整电源管理策略** ```bash # 禁用PCIe设备ASPM节能 echo "performance" > /sys/module/pcie_aspm/parameters/policy # 或针对特定设备 lspci -vvv | grep ASPM # 确认设备位置 setpci -s 01:00.0 CAP_EXP+0x08.b=0x0 ``` #### 4. **应用层行为优化** - 避免频繁创建/销毁队列:复用现有队列(如使用连接池) - 合并I/O操作:减少小粒度请求(例如批量提交读写) --- ### **三、诊断工具推荐** 1. **动态追踪调用栈** ```bash # 使用perf监控函数调用 perf probe -a 'TSSE_hw_stop_qpair' -a 'TSSE_hw_start_qpair' perf record -e probe:* -ag ``` 2. **中断频率分析** ```bash watch -n 1 "cat /proc/interrupts | grep qpair" ``` --- ### **典型日志模式对比** | **正常场景** | **异常场景** | |---------------------------|--------------------------------| | 启动时调用1次`start_qpair` | 每秒多次`stop/start`交替出现 | | 关闭时调用1次`stop_qpair` | 伴随`error=0x0x10`(链路错误) | | 无相关错误码 | 高频率出现(>10次/秒) | > 若调整后仍出现频繁调用,需收集完整日志及`ftrace`数据提交至硬件厂商分析[^3]。 --- **相关问题** 1. 如何区分硬件队列异常与软件配置错误? 2. NVMe-oF场景下队列重建的完整流程是什么? 3. 哪些工具可以量化队列启停对I/O性能的影响? [^1]: 硬件队列启停通常关联链路状态管理协议 [^3]: 驱动层对硬件寄存器的操作可能存在未公开行为 [^5]: 应用层操作可能通过ioctl间接触发硬件控制
