Android 应用程序中的 IOException

发布于 2024-09-13 07:28:01 字数 501 浏览 8 评论 0原文

我刚刚开始进行 Android 开发，并在 Android 应用程序中遇到一个问题。

当应用程序尝试从文件（原始资源）读取数据时，它会在 readLine() 函数上抛出 IOException。代码如下：

final Resources resources = m_ApplicationContext.getResources();
InputStream inputStream = resources.openRawResource(R.raw.datafile);
BufferedReader reader = new BufferedReader(new InputStreamReader(
   inputStream));

try {
 String line;
 while ((line = reader.readLine()) != null) {

reader.readLine() 函数抛出异常。我是否需要提及任何类型的附加权限来读取该文件？

提前致谢。

I have just started with Android development, and facing one issue in the android application.

When application tries to read the data from file (raw resources), it throws IOException on readLine() function. code is as below:

final Resources resources = m_ApplicationContext.getResources();
InputStream inputStream = resources.openRawResource(R.raw.datafile);
BufferedReader reader = new BufferedReader(new InputStreamReader(
   inputStream));

try {
 String line;
 while ((line = reader.readLine()) != null) {

the reader.readLine() function is throwing the exception. Do I need to mention any kind of additional permission for reading the file ?

Thanks in advance.
