[Solved]-Project has no target set. Edit the project properties to set one-eclipse

Go to Project » Properties » Java Build Path » Libraries and remove all except the "Android X.Y" (in my case Android 1.5). click OK. Go to Project » Clean » Clean projects selected below » select your project and click OK. That should work.

It is also possible that you have a JAR file located somewhere in your project folders (I had copied the Admob JAR file into my src folder) and THEN added it as a Java Path Library. It does not show up under the Package Explorer, so you don't notice it, but it does get counted twice, causing the dreaded Dalvik error 1.

This is because you firstly put the project files in the resourse path. Try to put the project in another file, and reimport it. It will work!!!

I just resolved my issue by setting the higher target. go to windows->preference->android and check on higher API available and click apply.

might work for you also.

I got this error when I copied the project folder 'google-play-services_lib' alone after separating it from its actual folder structure into my workspace and referenced it in my project. But I could resolve the error by referencing the project folder 'google-play-services_lib' with out separating it from its actual folder structure. Actual folder structure: google_play_services > libproject > google-play-services_lib.

Hope this helps!!!!!-)

[2009-05-27 12:18:36 - DroidGap] Project has no target set. Edit the project properties to set one.

I was able to solve this on the Projects > Properties > Android screen by:

• first selecting Google APIs (which was incorrect for my setup)
• and then reselecting Android 1.5 (which is correct and had previously been selected).

I was immediately able to run the emulator following this change.

My problem was that the target specified inside the project.properties file was not installed. It was "target=android-3", which is the Cupcake target.

I solved it by increasing the number to 8 (Froyo API) which is the oldest API level I had installed in my environment.

I got this error on the command line when I ran ./android update project -p . Basically I had to specify a target like so in order for it to work: ./android update project -p . --target android-10
