Bugsnag Notifier for Android

The Bugsnag Notifier for Android gives you instant notification of exceptions thrown from your Android applications. The notifier hooks into Thread.UncaughtExceptionHandler, so any uncaught exceptions in your app will be sent to your Bugsnag dashboard.

Bugsnag captures errors from your web and mobile applications, helping you to understand and resolve them as fast as possible. Create a free account to start capturing exceptions from your applications.

Installation & Setup

  • Download the latest bugsnag-android.jar and place it in your Android app's libs/ folder.

    Note: if your project uses Maven you can instead add bugsnag-android as a dependency in your pom.xml.

  • Import the Bugsnag package in your Application subclass.

  • In your application's onCreate function, register to begin capturing exceptions:

    Bugsnag.register(this, "your-api-key-goes-here");
  • Ensure you have the android.permission.INTERNET permission listed in your AndroidManifest.xml.

  • To track which of your activities were open at the time of any exception, you should also have each of your Activity classes inherit from BugsnagActivity:

    class MyActivity extends BugsnagActivity { ... }

    Note: If you are using the Android Support Library, ActionBarSherlock or have a custom base Activity, see Instrumenting Custom Activities below.

  • To enable network diagnostics for each device (internet connectivity, etc) you should also add the android.permission.ACCESS_NETWORK_STATE permission to your AndroidManifest.xml.

Sending Custom Data With Exceptions

It is often useful to send additional meta-data about your app, such as information about the currently logged in user, along with any exceptions, to help debug problems. To add custom data to every exception you can use addToTab:

Bugsnag.addToTab("User", "Name", "Bob Hoskins");
Bugsnag.addToTab("User", "Paying Customer?", true);

Send Non-Fatal Exceptions to Bugsnag

If you would like to send non-fatal exceptions to Bugsnag, you can pass any Throwable object to the notify method:

Bugsnag.notify(new RuntimeException("Non-fatal"));

You can also send additional meta-data with this exception:

import com.bugsnag.MetaData;

MetaData metaData = new MetaData();
metaData.addToTab("User", "username", "bob-hoskins");
metaData.addToTab("User", "email", "");

Bugsnag.notify(new RuntimeException("Non-fatal"), metaData);



Bugsnag uses the concept of "contexts" to help display and group your errors. Contexts represent what was happening in your application at the time an error occurs. In an android app, it is useful to set this to be your currently active Activity.

If you are using BugsnagActivity then this is set automatically for you. If you would like to set the bugsnag context manually, you can call setContext:



Bugsnag helps you understand how many of your users are affected by each error. In order to do this, we need to send along user information with every exception.

If you would like to enable this, set the user. You can set the user id, which should be the unique id to represent that user across all your apps, the user's email address and the user's name:

Bugsnag.setUser("userId", "", "User Name");


If you would like to distinguish between errors that happen in different stages of the application release process (development, production, etc) you can set the releaseStage that is reported to Bugsnag.


If you have the android:debuggable="true" flag set in your AndroidManifest.xml, we'll automatically set this to "development", otherwise it is set to "production".


By default, we will notify Bugsnag of exceptions that happen in any releaseStage. If you would like to change which release stages notify Bugsnag of exceptions you can call setNotifyReleaseStages:

Bugsnag.setNotifyReleaseStages("production", "development", "testing");


By default, we will automatically notify Bugsnag of any fatal exceptions in your application. If you want to stop this from happening, you can call setAutoNotify:



Sets the strings to filter out from the extraData maps before sending them to Bugsnag. Use this if you want to ensure you don't send sensitive data such as passwords, and credit card numbers to our servers. Any keys which contain these strings will be filtered.

Bugsnag.setFilters(new String[]{"password", "credit_card_number"});

By default, filters is set to new String[] {"password"};


Sets which package names Bugsnag should consider as "inProject". We mark stacktrace lines as in-project if they originate from any of these packages.

Bugsnag.setProjectPackages("", "");

By default, projectPackages is set to be the package you called Bugsnag.register from.


Sets for which exception classes we should not send exceptions to Bugsnag.

Bugsnag.setIgnoreClasses("", "com.example.Custom");

Instrumenting Custom Activities

Bugsnag can add additional diagnostic information to each error by instrumenting your Activity classes.

If you are using FragmentActivity from the Android Support Library your Activities should inherit from BugsnagFragmentActivity.

Similarly, if you are using SherlockActivity or SherlockFragmentActivity from ActionBarSherlock, your Activities should inherit from BugsnagSherlockActivity or BugsnagSherlockFragmentActivity.

If you have your own custom base Activity, you can add the Bugsnag instrumentation manually by calling Bugsnag.onActivityPause in onPause, Bugsnag.onActivityResume in onResume, Bugsnag.onActivityCreate in onCreate and Bugsnag.onActivityDestroy in onDestroy. Each of these methods take one paramenter, the activity instance (usually this).

Building from Source

To build a .jar file from source you'll need to use Maven.

Clone the bugsnag-android repository, then run:

mvn clean package

This will generate jar files in the target directory.

Building on OSX

In order to build on OSX, run the following commands,

cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib
sudo ln -s ../../Classes/classes.jar rt.jar
sudo ln -s ../../Classes/jsse.jar .
