Protecting Android Applications That Use Crashlytics

July 2, 2018 4960 Views Johnny
support

With our recent DashO releases, we’ve been working to make our Android support even easier to use. A great example of this is our evolved support for Crashlytics, which is an analytics framework that can provide detailed reports on application crashes from the field.

When applications have been obfuscated, the stack traces will contain obfuscated class and method names. To prevent this from complicating debugging, Crashlytics provides a utility to automatically deobfuscate stack traces, so that the reporting server shows the original class and method names. It does so by reading the map file, which is a file created by the obfuscation tool to pair the obfuscated class and method names with the original names. Crashlytics expects this map file to be in a ProGuard-compatible format, which differs from the DashO map file format.

If you were using Crashlytics with a version of DashO prior to our 8.5, this would likely have caused issues. You might have experienced an error during the Gradle build, from the Crashlytics plugin:

A problem occurred configuring project ':app'. > path may not be null or empty string. path='null'

To resolve this build error, you could add custom scripting to your build.gradle file to call DashO's ConvertMap utility, which could convert the DashO map file into ProGuard format.

After adding the custom scripting, your Gradle build would complete. However, when you viewed your Crashtlyics portal, you still might see obfuscated stack traces:


… Caused by java.lang.ArithmeticException: Could not complete product registration
at classes.foobaz.f(Unknown Source)
at classes.foobaz.k(Unknown Source)
at classes.foobaz.q(Unknown Source)
at classes.foobar.a(Unknown Source)
at classes.foobar.w(Unknown Source)
at com.example.the.crashlyticsexample.MainActivity.forceCrash(Unknown Source)
at java.lang.reflect.Method.invoke(Method.java)
at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:384)
at android.view.View.performClick(View.java:5198)
at android.view.View$PerformClick.run(View.java:21147)
at android.os.Handler.handleCallback(Handler.java:739)
at android.os.Handler.dispatchMessage(Handler.java:95)

In order to ensure that the stack traces appeared in an unobfuscated format, additional settings were required in your dasho.gradle file.

With our 8.5 version, after initially running your Android project through the Wizard, DashO will automatically manage the translation of the map file from DashO map format to ProGuard format, and put it where Crashlytics expects to find it, so that it will be uploaded to the Crashlytics server without any additional configuration.

While DashO continues to support a full range of Java applications, we’ve been paying special attention to our support of Android applications. This is just one of several reasons why you should always stay current with your DashO version.

Protecting Java applications that use Jackson for JSON



JSON is a standard format for sharing objects and data within an application. When working in Java, there is no built-in support for JSON processing. There are, however, several widely-used libraries and options to choose from. In this article, we will focus on Jackson, which is one of the most popular.

Inventa, Wireless Technology Company, Protects their Android Application with DashO



Inventa, a Wireless Technology Company, Protects their Android Application with DashO

The Beginnings of Inventa

Having worked in the wireless mobile technology domain in the US, Anand Virani, became intrigued by the growing tech and wireless trends and wanted to explore the field more for himself. He noticed a boom in the Internet of Things (IoT) and that smartphones were becoming more central to how people interacted with each other at home, in the office, and in public places. What if there was a way phones could connect with each other without the need for Internet or cloud access? Smartphones were the future and Virani was determined to make a profitable business model based on this new trend.

Surgical Theater Protects their Medical Applications with Dotfuscator



Surgical Theater Protects their Medical Applications with Dotfuscator

How It All Started

How is flying a fighter plane similar to performing neurosurgery? They have more in common than you’d think. In 2005, Monty Avisar and Alon Geri, two Israeli fighter pilots were assigned to work with Lockheed Martin to build a $50 million F-16 Flight Simulator program for the Israeli Air Force to improve hand-eye coordination skills for their pilots during combat. Avisar took on the role of project manager and Geri served as senior engineer; the project was a success.

Four years later in 2009, the two finished their military service in Israel and moved to Cleveland, Ohio. Their experience working in virtual reality applications inspired them to wonder where this technology could also be applied. With several connections to surgeons, the two came to understand the ins and outs of operation procedures; in a similar way, surgeons were also working on a battlefield. What if surgeons could also train like fighter pilots and preview their surgical procedure, much like a fighter pilot could pre-fly their mission? The surgeons could pre-plan the operation from every angle and every approach to increase their situational awareness. And a year later, Surgical Theater was born.

Integrating DashO into a Maven Build



Maven is perhaps the most widely-used project management tool for Java. Based on the Project Object Model (POM), it is used not only for compilation of source code, but also dependency management, documentation, running tests, packaging, deployment, and more. We are frequently asked if we have a Maven plugin for running DashO. Though we do not offer a specific Maven plugin, adding DashO to your Maven-based project is surprisingly easy by leveraging Ant.
