Issues

Activity class does not exist

Trying to install two applications and had various errors including:

Error: Activity class {com.sample/com.sample.BasicIntent} does not exist.

…and…

[2009-08-30 14:40:40 - BasicIntent] ActivityManager: Starting: Intent { comp={com.sample/com.sample.BasicIntent} }
[2009-08-30 14:40:40 - BasicIntent] ActivityManager: Error type 3
[2009-08-30 14:40:40 - BasicIntent] ActivityManager: Error: Activity class {com.sample/com.sample.BasicIntent} does not exist.
[2009-08-30 14:42:54 - com.android.ide.eclipse.common.project.AndroidManifestParser] Parser exception for /BasicIntent/AndroidManifest.xml: Element type "activity" must be followed by either attribute specifications, ">" or "/>".
[2009-08-30 14:42:54 - BasicIntent] Error in an XML file: aborting build.

Both applications had the same package name in the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sample"

To solve the issue, I used different package names for each application:

package="com.sample.app"
package="com.sample.intent"

Animation

There is a bug in the 1.5 version of the emulator. It needs to be re-started each time there is a change in the animation settings.

Debug Certificate expired

To solve this problem:

rm ~/.android/debug.keystore

For details, see Debug Certificate expired

Unable to resolve superclass…

If using the Google Map API, make sure you have included the following in your AndroidManifest.xml file:

    <uses-library
        android:name="com.google.android.maps" />
</application>

R cannot be resolved

Start by checking the Problems tab to make sure there are no errors in the XML files.

Eclipse sometimes likes to add an import android.R statement at the top of your files that use resources, especially when you ask Eclipse to sort or otherwise manage imports. This will cause your make to break. Look out for these erroneous import statements and delete them.

For details, see R cannot be resolved

If you create packages below the package shown in the manifest, then import the auto-generated R file e.g. import my.package.R

USB Driver for Windows
