ClassName.class.getResourceAsStream returning Null

Question

I migrated project from Eclipse to Android Studio. App compiles fine, but it has a crash related to nekohtml library.

Inside HTMLEntities class

//filename = "res/HTMLlat1.properties"
final InputStream stream = HTMLEntities.class.getResourceAsStream(filename);

stream is always null. I tried to move file to the same folder as class and gave full path like this

filename = "/org/cyberneko/html/res/HTMLlat1.properties"

Any ideas?

You should use filename = "/org/cyberneko/html/res/HTMLlat1.properties" instead of filename = "/org.cyberneko.html/res/HTMLlat1.properties" or use relative paths. This could be explained in this way: jar (jar is an example, maybe you're running your code from *.class in some directory) is just some kind of file system with it's root ("/") and all the files in the packages are in some subdirectories and you should specify the paths for them.

@Minas, ok, so, I'm not right, please, give us then the content of the resulting jar (with `jar tf`) – Dmitry Ginzburg Jun 08 '14 at 11:40
http://pastebin.com/guAm6gme hmm /org/cyberneko/html/res/ is missing from the jar, but it is there in source – Minas Jun 08 '14 at 11:55
You really should take a closer look at the project's properties. – Dmitry Ginzburg Jun 09 '14 at 10:17
Yes, you are right. I'm new to IntelliJ, so I'm not sure why it is ignoring properties file. Eclipse add this files to the jar without any problem – Minas Jun 09 '14 at 11:07

Same problem here.., my path properly worked at Eclipse but Android Studio. Don't know what to do... – Zin Win Htet Mar 23 '15 at 10:11
@CristyYG Show your `build.gradle` (under project root) please. – Dmitry Ginzburg Mar 23 '15 at 11:03
apply plugin: 'com.android.application' android { compileSdkVersion 19 buildToolsVersion "21.1.2" defaultConfig { applicationId "com.xavey.android" minSdkVersion 17 targetSdkVersion 19 } buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt' } } } dependencies { compile 'com.android.support:support-v4:19.0.0' compile 'com.google.code.gson:gson:1.7.1' } – Zin Win Htet Mar 23 '15 at 11:17
@CristyYG, okay, the where's your resources located? – Dmitry Ginzburg Mar 23 '15 at 13:43
@CristyYG I just asked where they're located in your FS. Something like `$PROJECT_ROOT/src/main/resources/com/xavey/android/util/...` – Dmitry Ginzburg Mar 24 '15 at 07:28
/src/main/java/com/xavey/android/util/xavey_properties_.properties – Zin Win Htet Mar 24 '15 at 07:59
@CristyYG then I'm sure, I know the problem. Only java files are processed under `src/main/java/...`. You should move all your resources to `src/main/resources` (keeping the structure) – Dmitry Ginzburg Mar 24 '15 at 08:19
@DmitryGinzburg , the same. – Zin Win Htet Mar 25 '15 at 05:26
I changed the path to /src/main/res/xavey_properties_.properties. Still null. – Zin Win Htet Mar 25 '15 at 05:27
@CristyYG You should use exactly `resources`, not `res`! – Dmitry Ginzburg Mar 25 '15 at 07:16
My project only contains res folder. But when I made new project "helloworld". It does. Should I create manually resource folder under my project? – Zin Win Htet Mar 26 '15 at 05:29
@CristyYG, yes, you have to. – Dmitry Ginzburg Mar 26 '15 at 09:03
