    copied!<p>For sample applications and debugging purposes, I use a simple solution that allows me to write the stacktrace to the sd card of the device and/or upload it to a server. This solution has been inspired by Project <a href="https://code.google.com/archive/p/android-remote-stacktrace/" rel="noreferrer">android-remote-stacktrace</a> (specifically, the save-to-device and upload-to-server parts) and I think it solves the problem mentioned by Soonil. It's not optimal, but it works and you can improve it if you want to use it in a production application. If you decide to upload the stacktraces to the server, you can use a php script (<code>index.php</code>) to view them. If you're interested, you can find all the sources below - one java class for your application and two optional php scrips for the server hosting the uploaded stacktraces.</p> <p>In a Context (e.g. the main Activity), call</p> <pre><code>if(!(Thread.getDefaultUncaughtExceptionHandler() instanceof CustomExceptionHandler)) { Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler( "/sdcard/&lt;desired_local_path&gt;", "http://&lt;desired_url&gt;/upload.php")); } </code></pre> <p><strong><code>CustomExceptionHandler</code></strong></p> <pre><code>public class CustomExceptionHandler implements UncaughtExceptionHandler { private UncaughtExceptionHandler defaultUEH; private String localPath; private String url; /* * if any of the parameters is null, the respective functionality * will not be used */ 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 = TimestampFormatter.getInstance().getTimestamp(); final Writer result = new StringWriter(); final PrintWriter printWriter = new PrintWriter(result); e.printStackTrace(printWriter); String stacktrace = result.toString(); printWriter.close(); 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)); bos.write(stacktrace); bos.flush(); bos.close(); } catch (Exception e) { e.printStackTrace(); } } private void sendToServer(String stacktrace, String filename) { DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); List&lt;NameValuePair&gt; nvps = new ArrayList&lt;NameValuePair&gt;(); nvps.add(new BasicNameValuePair("filename", filename)); nvps.add(new BasicNameValuePair("stacktrace", stacktrace)); try { httpPost.setEntity( new UrlEncodedFormEntity(nvps, HTTP.UTF_8)); httpClient.execute(httpPost); } catch (IOException e) { e.printStackTrace(); } } } </code></pre> <p><strong><code>upload.php</code></strong></p> <pre><code>&lt;?php $filename = isset($_POST['filename']) ? $_POST['filename'] : ""; $message = isset($_POST['stacktrace']) ? $_POST['stacktrace'] : ""; if (!ereg('^[-a-zA-Z0-9_. ]+$', $filename) || $message == ""){ die("This script is used to log debug data.
