Crasher is a library built to allow users to easily send stack traces and useful device info to developers without the use of third party services. For demonstration purposes, sample APKs can be downloaded here.

The Gradle dependency is available through jCenter, which is used by default in Android Studio. To add the dependency to your project, copy this line into the dependencies section of your build.gradle file.
Setting the Exception Handler
new Crasher(context) will automatically set Crasher as the default exception handler in the current thread. This will need to be done in every thread that your application uses, or every thread that you want Crasher to intercept exceptions from.
It is recommended to store one instance of
Crasher in your app's
Application class, and simply pass that to
Thread.setDefaultUncaughtExceptionHandler(crasher) in each new thread that you create. If you do not engage in the fine art of multithreading, then you do not need to worry about this, and only need to create one
Crasher, either in the
onCreate method of your
Application class, or the
onCreate of the first
Activity that is opened by your app.
R.string.app_name as the name of the application to display in the toolbar. The default value of this is "Crasher", but can easily be changed by setting the
app_name string resource in your strings.xml file.
To specify an email for the user to optionally send crash reports to, simply call
crasher.setEmail(email) and pass the desired email as a string, or pass
null to remove the button (this will be obsolete in most cases, since it is not displayed by default unless an email is passed).
By default, Crasher will use
#F5F5F5 as its primary color, which can be overriden by either creating the
colorPrimary resource in your application or calling
crasher.setColor(color) on the
Crasher can also optionally open the search results of the exception message on stackoverflow when the app crashes. This may be somewhat annoying during "regular use", as it would take much more time to solve common errors that most developers know on sight (missing a declaration in the manifest, for example), and is really just here for show. You can enable it for debug builds of the application only by calling
crasher.setStackoverflowEnabled(true), or for all builds by calling
crasher.setForceStackOverflow(true) (I'm not sure what I was thinking when I decided on the capitalization for those two methods, but I can't be bothered to fix it right now so they'll probably stay for a while).

crasher.setCrashActivityEnabled(isCrashThingyEnabled). Pretty self-explanatory.
You can override any string resource the app uses by specifying it in your own strings.xml file (if you want to make your own translations, for example). The strings used by Crasher are as follows:
|Resource Name||Value||Used For|
|app_name||Crasher||The app's name in the action bar title/other random strings|
|title_crashed||%1$s Crashed||The action bar title, with String.format|
|title_email||%1$s in %2$s||I honestly can\'t remember, I'll update this later when I figure it out|
|msg_crashed||Unfortunately, %1$s has stopped working. You can report this as a bug using the buttons below, or you can try to fix it yourself. When reporting the bug, please include as much detail as possible to help fix the issue as quickly as possible. Please note that your device info, such as the manufacturer and model number, may be included in the bug report.||The message displayed to the user when a crash occurs|
