java - Android application throws Guice exception -
i'm new in android applcation , wrong. i've tried compile application javampd modue throws exception: "com.google.inject.internal.util.$computationexception: com.google.inject.internal.util.$computationexception: java.lang.exceptionininitializererror" @ biulder creation:
try { mpd.builder mpdbuilder = new mpd.builder(); } catch (exception error) { string text = error.getmessage(); toast.maketext(this, "exception: " + text, toast.length_long).show(); } i've traced exception guice , figured out exception throwing inside javampd module
injector = guice.createinjector(new mpdmodule()); here full stack trace:

although android apps written in java, cannot take java libraries , use them in android app without configuration issues.
if library, java mpd, depends internally on guice, difficult use as-is inside android project. because guice has number of configuration issues working android. besides, there other issues consider. demonstrate, quote faq of 1 of other di frameworks android:
- guice slow, @ least didn't match more expected performance of android apps.
- guice 4 uses guava contains tens of thousands of methods contribute multidex issues , heavy apks
- guice uses reflection , reflection slow on android. because there no jit of reflection code opposed pc jvms.
you try using roboguice, uses fork of guice , annotations processor around guice's use of reflection , other integration issues android. if provides enough of guice classes make mdp library work surprised. otherwise, have find library use.
