Question #: 59
Topic #: 5

[All Associate-Android-Developer Questions]

For example, we have a BufferedReader reader, associated with the json file through

InputStreamReader. To get a file data we can do this:

Avar line: String? try {
while (reader.readLine().also { line = it } != null) { builder.append(line)
}
val json = JSONObject(builder.toString())
return json
} catch (exception: IOException) {
exception.printStackTrace()
} catch (exception: JSONException) {
exception.printStackTrace()
}

Bvar line: JSONObject ? try {
while (reader.readJSONObject ().also { line = it } != null) {
builder.append(line)
}
val json = JSONObject(builder.toString())
return json
} catch (exception: IOException) {
exception.printStackTrace()
} catch (exception: JSONException) {
exception.printStackTrace()
}

Cvar line: String? try {
while (reader.readLine().also { line = it } != null) { builder.append(line)
}
val json = JSONObject(builder.toString())
return json
} catch (exception: RuntimeException) {
exception.printStackTrace()
} catch (exception: ArrayIndexOutOfBoundsException) {
exception.printStackTrace()
}

Yeah, returning false would be like hiding the menu from the users. Not a good idea at all.
