ResumeUploader的RandomAccessFile file 使用后未关闭 #135
Description
若使用以下代码开启StrictMode， 会在文件上传后抛出异常，应用退出，提示相应的RandomAccessFile未关闭。
if (BuildConfig.DEBUG && Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork() // or .detectAll() for all detectable problems
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
}异常：

将StrictMode的开启代码移除后，应用就不会直接退出了，但提示的RandomAccessFile未关闭，应该是存在的。 我大致看了下com.qiniu.android.storage.ResumeUploader的代码，貌似确实没有关闭代码。
这个应该是要处理下的， 否则文件上传后，相应的文件对象都没有关闭，长期操作会不会对应用产生影响。
