Read file As String
Solution 1:
The code finally used is the following from:
http://www.java2s.com/Code/Java/File-Input-Output/ConvertInputStreamtoString.htm
public static String convertStreamToString(InputStream is) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
reader.close();
return sb.toString();
}
public static String getStringFromFile (String filePath) throws Exception {
File fl = new File(filePath);
FileInputStream fin = new FileInputStream(fl);
String ret = convertStreamToString(fin);
//Make sure you close all streams.
fin.close();
return ret;
}
Solution 2:
You can use org.apache.commons.io.IOUtils.toString(InputStream is, Charset chs)
to do that.
e.g.
IOUtils.toString(context.getResources().openRawResource(<your_resource_id>), StandardCharsets.UTF_8)
For adding the correct library:
Add the following to your app/build.gradle file:
dependencies { compile 'org.apache.directory.studio:org.apache.commons.io:2.4' }
