How can I get a resource content from a static context?
Here is a "fast and furious" method using theClassLoader
's getResourceAsStream()
. Yeah, Hollywood isn't the only one dealing with class loaders.
Replace YourClass
with your class and replace "path/to/resource" with the relative path to your resource. This InputStream
acts as the red carpet roll out for the content in your resource.
For those brave souls working in an Android jungle, where you rub shoulders with Resources without an Activity
or Context
, behold: the static application context.
Application subclass: Your secret trick in Android
-
Create an Android Application subclass:
This code snippet makes Atlas, who eternally bears the world on his shoulders, look like a amateur. Our
MyApp
class is born, ready to shoulder resource loads statically! -
Embrace this Application subclass in
AndroidManifest.xml
:Just like the Stamp of Approval on your college degree.

Looking for resources? Here is your key:
You are now the master of Resource-land! Take a bow. But watch out for dragons... I mean, memory leaks or any other architecture concerns.
Use system resources, like a boss!
Want to access breadcrumbs left by the Android OS? Resources.getSystem()
comes to your rescue:
Remember, this method works only for system-level resources. You wouldn't want to go to the cops looking for homemade pie, would you?
Instances where static context could give you a cold shoulder
While a static context can be your knight in shining armor, it does have its quirks. Brace yourselves for some:
- Possible Memory Leaks: Static contexts can leave you staring at retained references long after your app has said goodbye.
- Lifecycle Awkwardness: Application contexts, just like socially awkward nerds, are completely unaware of Activity or Fragment lifecycles.
- Resource Qualifiers: Static contexts may not understand resource qualifiers such as locales or screen sizes. Well, they did never pay attention in geography lessons.
The Old School Ways: Properties and Resource Bundles
Grandpa Java used to regale us with stories of accessing properties files or resource bundles, done statically:
Old man Java used resource bundles for cracking the code of localization:
These meds may be old, but they can cure your Context
-less woes.
