How to display long messages in logcat

Question

I am trying to display long message on logcat. If the length of message is more than 1000 characters, it gets broken.

What is the mechanism to show all characters o

Answer 1

Here is a Kotlin version for the @spatulamania answer (especially for lazy/smart peooples):

val maxLogSize = 1000
val stringLength = yourString.length
for (i in 0..stringLength / maxLogSize) {
    val start = i * maxLogSize
    var end = (i + 1) * maxLogSize
    end = if (end > yourString.length) yourString.length else end
    Log.v("YOURTAG", yourString.substring(start, end))
}

For an easy solution, use Use soft wrap option in below attach point no 4 options might help you.

Answer 3

In order not to minimize splitting lines across log messages, I take the large string and log each line separately.

void logMultilineString(String data) {
    for (String line : data.split("\n")) {
        logLargeString(line);
    }
}

void logLargeString(String data) {
    final int CHUNK_SIZE = 4076;  // Typical max logcat payload.
    int offset = 0;
    while (offset + CHUNK_SIZE <= data.length()) {
        Log.d(TAG, data.substring(offset, offset += CHUNK_SIZE));
    }
    if (offset < data.length()) {
        Log.d(TAG, data.substring(offset));
    }
}

If logcat is capping the length at 1000 then you can split the string you want to log with String.subString() and log it in pieces. For example:

int maxLogSize = 1000;
for(int i = 0; i <= veryLongString.length() / maxLogSize; i++) {
    int start = i * maxLogSize;
    int end = (i+1) * maxLogSize;
    end = end > veryLongString.length() ? veryLongString.length() : end;
    Log.v(TAG, veryLongString.substring(start, end));
}
