How to Obtain Crash Data from Your Android Application

Understanding how to efficiently gather crash data from your Android application is pivotal for maintaining a robust and user-friendly app. This guide will walk you through several methods to collect and analyze crash data, enabling you to improve your application’s stability.

Methods to Collect Crash Data

1. Using ACRA (Application Crash Report for Android)

ACRA is a popular library that allows Android applications to automatically post their crash reports to a Google Doc form. It’s designed to help developers gather data from their applications when they crash or behave unexpectedly. Here are some key features:

  • Easy to install and configure within your app.
  • No need to host a server script as reports are sent to a Google Doc spreadsheet.
  • Highly configurable to suit your needs.

ACRA is an efficient way to collect crash data without requiring extensive infrastructure setup.

2. Custom Exception Handling

For a more hands-on approach, you can set up a custom exception handler that writes the stack trace to the device’s storage or uploads it to a server. Here’s a simple implementation:

public class CustomExceptionHandler implements Thread.UncaughtExceptionHandler {
    private UncaughtExceptionHandler defaultUEH;
    private String localPath;
    private String url;

    public CustomExceptionHandler(String localPath, String url) {
        this.localPath = localPath;
        this.url = url;
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();

    public void uncaughtException(Thread t, Throwable e) {
        String timestamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
        String stacktrace = Log.getStackTraceString(e);
        String filename = timestamp + ".stacktrace";

        if (localPath != null) {
            writeToFile(stacktrace, filename);
        if (url != null) {
            sendToServer(stacktrace, filename);

        defaultUEH.uncaughtException(t, e);

    private void writeToFile(String stacktrace, String filename) {
        try (BufferedWriter bos = new BufferedWriter(new FileWriter(localPath + "/" + filename))) {
        } catch (IOException e) {

    private void sendToServer(String stacktrace, String filename) {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            List nvps = new ArrayList();
            nvps.add(new BasicNameValuePair("filename", filename));
            nvps.add(new BasicNameValuePair("stacktrace", stacktrace));
            httpPost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
        } catch (IOException e) {

This method allows you to store crash data locally and/or send it to a remote server for further analysis.

3. Firebase Crashlytics

Firebase Crashlytics is a powerful tool for tracking and analyzing app crashes. It provides detailed insights into crash data, including stack traces, device information, and user actions leading up to the crash. To integrate Firebase Crashlytics:

  • Include the Firebase Crashlytics dependency in your build.gradle file.
  • Initialize Crashlytics in your Application class.
  • Automatic collection of crash reports without requiring user intervention.

Firebase Crashlytics is a comprehensive solution for monitoring the health of your application.


Collecting crash data is crucial for improving the stability and reliability of your Android application. Whether you choose ACRA, custom exception handling, or Firebase Crashlytics, each method provides unique benefits to help you gather and analyze crash data effectively.
