An internal error occurred during: "Launching com.tcds.BT_activity_root". java.lang.NullPointerException. I get it when I try to run it as an app. I checked the color codes and they were corrected. I've deleted from eclipse and re-imported the file and cannot find what is wrong. The only change I did was change the AVD which was wrong. When I had the wrong one it actually worked. I hope someone can help me. Title Comments Hi, Yesterday my project was working great and now I get this error.

Do you have any red crosses next to any of the files in the project? If not, try a bit of project cleaning. Right click project name in the lefthand pane, go to Android > Fix project properties. Next, in the tabs along the top select Project > Clean, then right click in the lefthand pane and hit refresh. If you do have any red crosses, open the file with the cross, find the line with the error, hover your mouse over the red line and it'll give you some more information. It might be an easy fix, or post it here. Comments No, that's ok. I meant 3rd party app plugins. Do you have any red crosses next to any of the files in the project?

It records everything that happens as the app is running, and the NullPointerException that it logs is key to understanding what's going on with your app. Did you make any changes to your app in the control panel at all?

They're just warnings about which java files aren't actually being used. You could have the ability to bring up an Errors pane. Is there anything there? In general, warnings are OK, and they won't prevent the app from compiling. But it's odd that it's crashing before it even gets installed to the emulator. Something somewhere (perhaps in the Console pane) should get logged. If you want, you can send me your zipped source package and I can try to replicate the problem.

The only error I got was this: [2012-07-27 15:07:51 - buzzTouch] Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties. I did the Fix Project Properties, and everything worked as expected. So, if you did recently just download the Java JDK, I'd follow @Fred's suggestion and make sure that you have both 32-bit Java and Eclipse or both 64-bit Java and Eclipse, and that they aren't mixed. Personally, I'd stick with the 32-bit version. If that all checks out, then it must be something else. But one step at a time. Mark Comments Very nice app! I love the button menu!

GoNorthWest buzztouch Evangelist Posts: 8197 Reg: Jun 24, 2011 Oro Valley, AZ 1,000,000	07/27/12 03:31 PM (13 years ago) I looked around my Eclipse install, and I'm not quite sure! I do see that you're using Eclipse for Java EE Developers. Pretty much all of us here use the Eclipse Classic. I don't know how much it all plays into it, but I might suggest installing that instead of the one you have. I think it's a much simpler version. It appears the Java you are using is 32-bit, so grab the 32-bit Eclipse. Mark Comments I looked around my Eclipse install, and I'm not quite sure!

Might take a while as I'm at work. If you want to send me your zipped code package, I can try and load it in my Eclipse just to make sure it's not an issue with the source.

Moto110 Aspiring developer Posts: 205 Reg: Jul 26, 2011 Orlando, FL 8,700	01/29/13 02:26 PM (13 years ago) Did you ever get this problem resolved? I'm running into a very similar problem with a BT 2.0 Android app that was compiling fine and it seems that out of nowhere I started getting this same error. An internal error occurred during: "Launching com.APPNAME.BT_activity_root". java.lang.NullPointerException. Comments Did you ever get this problem resolved?

Moto110 Aspiring developer Posts: 205 Reg: Jul 26, 2011 Orlando, FL 8,700	01/29/13 02:37 PM (13 years ago) I figured it out about five minutes after posting. Here is how I fixed it. I deleted the project from Eclipse and added it back as an existing project. Changed the API to Google 2.2 as usual and after that it compiled fine.
