我写了一个简单的应用程序，它可以从相机中获取所有照片并通过FTP将它们上传到服务器。当我运行应用程序时，我得到一个非常奇怪的例外。
09-12 11:56:08.153: E/ThrottleService(149): problem during onPollAlarm:
java.lang.IllegalStateException: problem parsing stats: java.io.FileNotFoundException:
/proc/net/xt_qtaguid/iface_stat_all: open failed: ENOENT (No such file or directory)
FTP客户端也返回：550 file not found
文件上传代码：
@Override
public boolean storeFile(File file) {
FileInputStream in = null;
try {
client.enterLocalActiveMode();
client.setFileType(FTP.BINARY_FILE_TYPE);
Log.d(TAG, "File exists: " + file.exists() + " File readabdle: " + file.canRead() + " File writable: " + file.canWrite());
in = new FileInputStream(file);
boolean result = client.storeFile(file.getName(), in);
in.close();
return result;
} catch (IOException e) {
e.printStackTrace();
try {
in.close();
return false;
} catch (IOException e1) {
e1.printStackTrace();
return false;
}
}
}
请注意，日志打印：
09-12 12:03:21.701: D/FTPClientApache(745): File exists: true File readabdle:
true File writable: true
我也尝试启用FTP日志（抱歉这个长度，但我觉得更长=更好）：
