问题:

I have a class that handles Guice bindings. It is the very first thing that needs to run, called ApplicationAutoworkout.java.

package com.redsoft.android.autoworkout;

import java.util.List;

import roboguice.application.RoboApplication;

import com.google.inject.Module;
import com.redsoft.android.autoworkout.service._ModuleQueryFor;
import com.redsoft.android.autoworkout.service._ModuleService;
import com.redsoft.android.autoworkout.ui._ModuleUi;

public class ApplicationAutoworkout extends RoboApplication {
     private Module testModule;

@Override
protected void addApplicationModules(List<Module> modules) {
    modules.add(new _ModuleUi(this.getApplicationContext()));
    modules.add(new _ModuleService(this.getApplicationContext()));
    modules.add(new _ModuleQueryFor());

    if (testModule!=null)modules.add(testModule);

    super.addApplicationModules(modules);
}
    //Allows the testModule to be added during tests
    public void setModule(Module module) {
        this.testModule = module;
    }

}

This class, for whatever reason, cannot be found by the Android emulator when it is built/deployed from eclipse

However, if I run this from the command line:

mvn clean process-classes android:dex android:apk android:deploy

everything works. What's going on in Eclipse that keeps Android from finding the class?

EDIT: Here's the AndroidManifest.xml.

回答1:

The problem is that the Android Development Toolkit Eclipse plugin does not support Maven dependencies. If you want to use it you need to use the m2e-android Android Configurator extension for M2E:

http://rgladwell.github.com/m2e-android



回答2:

Just a guess, but is it possible your AndroidManifest is looking for the application class com.redsoft.android.autoworkout.ApplicationAutoworkout when the class has been renamed/moved?

I find that the manifest gets a wrong value in it now and then even if I don't do a move/rename.
