I'm working on my first android app using the walk-through provided by Android and I'm running into a problem (well, more than a few, but I can't find a solution to this one).

When I try to run the app in the Emulator I get the following error:

am get-config: retrieve the configuration and any recent configurations of the device

Error: Bad component name: com.example.sir.geo_app/

Here's my Manifest:

    <application

            </intent-filter>

                android:name="android.support.PARENT_ACTIVITY"
                android:value="com.example.sir.geo_app.MyActivity" />
        </activity>
    </application>

</manifest>

Any help would be gratefully appreciated.

Thanks in advance!

You can't have an "_" in your java package name. So com.example.sir.geo_app should be com.example.sir.geo.app or com.example.sir.geoapp.

In Android this is illegal, see the answer here: Android - Package Name convention.

In Java, it should be alright: http://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html.

  • This is proving to be problematic. Here's what I've done so far.. I renamed the folder Geoapp, and went through and edited all of the package and app names from geo_app to geoapp. I'n now getting errors in the DisplayMessageActivity saying that package R does not exist. – Matt M Mar 16 '15 at 02:58
  • `/Users/Sir/Desktop/AndroidStudioProjects/Geoapp/app/src/main/java/com/example/sir/geo_app/DisplayMessageActivity.java Error:(15, 21) package R does not exist Error:(21, 44) cannot find symbol variable MyActivity Error:(41, 20) package R does not exist /Users/Sir/Desktop/AndroidStudioProjects/Geoapp/app/src/main/java/com/example/sir/geo_app/MyActivity.java Error:(49, 42) cannot find symbol class DisplayMessageActivity` – Matt M Mar 16 '15 at 02:59
  • How do I change the location that it looks for the files in? – Matt M Mar 16 '15 at 03:00
  • All you have to do is Change the Package name. Right-click -> refactor -> rename. – Jared Burrows Mar 16 '15 at 03:02

    I just tried but it requires 15 points. I certainly will when I get the privileges – Matt M Mar 16 '15 at 03:58
  • Hmm.. I had to troubleshoot through a bunch of errors from moving the files, and I think I was premature in marking this as complete. I'm still receiving the Bad component error: com.example.sir.geo_app/ – Matt M Mar 16 '15 at 04:30
  • ` ... ` – Matt M Mar 16 '15 at 04:32
  • I had used the Rightclick > refactor > rename function to rename all of the mentions of geo_app to geoapp – Matt M Mar 16 '15 at 04:32
  • @MattM Not premature, you are on the right track. Is there anything else I can help you with? – Jared Burrows Mar 16 '15 at 05:06
  • Thanks - I'm still getting the same error about the Bad component error: com.example.sir.geo_app even the name had been changed using the Refactor > Rename process. Here is my manifest: http://imgur.com/ZWlSJJK I also noticed that the – Matt M Mar 16 '15 at 14:49
  • Are you using Android Studio, correct? Did you just start this project? Have you tried cleaning it? If your project is not that large, I'd simply create a new one with the CORRECT package name and copy your code over. – Jared Burrows Mar 16 '15 at 15:32
  • Yeah, correct. I'm using Android Studio. I tried using the Clean function, and also the Invalidade Caches/Restart and neither worked in fixing the error. Here's the message I get when trying to use the Emulator. – Matt M Mar 16 '15 at 17:11

  • Post your `build.grade`. Maybe you are renamed your packages in there. Like I said, the best way is simply to copy your sources to a new project. Just name your project correctly the first time. – Jared Burrows Mar 16 '15 at 17:24
  • Ideally I'd like to figure this out instead of redoing it as there's lots of files that I've created and I don't want to overlook something and run through more troubleshooting than is necessary. – Matt M Mar 16 '15 at 17:42
  • You have not been able to run the app at all correct? This is why you asked the question in the first place. Do you even have a lot of code in your app? Its hard to debug it through pictures. – Jared Burrows Mar 16 '15 at 17:47
  • Correct - the Run stops with the error, and if I try to click on the icon in the emulator I get a Unfortunately, My first App has stopped. – Matt M Mar 16 '15 at 18:06
  • I really have done all I can here. You just started this project. You should not have named your project with an "_" inside of it. To be safe, I would create a new project and add your code to that one. – Jared Burrows Mar 16 '15 at 18:11
  • I appreciate your help! I'm in the process of redoing the project now based on your suggestion – Matt M Mar 16 '15 at 18:12
  • Anytime! Let me know if I can help on anything else. – Jared Burrows Mar 16 '15 at 18:12
