Android Development with Java 7 and Mac OS X.

First: yes it is possible to use Java 7 to develop Android. However there are two problems.

First Java 6 used a rather strange directory layout. Strange for the average UNIX™ user. Not so strange for unencumbered user as the names used are more readable and understandable.

Since a lot of tools got used to the Java 6 names we need two compatibility links:

pushd /Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home/
sudo ln -s jre/lib Classes
cd jre/lib
sudo ln -s rt.jar classes.jar
popd

Java 7 also comes with an new jar signer which by default uses a new algorithm. Android devices can't use that algorithm so you have to force the signer to use the old algorithm:

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jarsigner-plugin</artifactId>
        <executions>
          <execution>
            <id>signing</id>
            <goals>
              <goal>sign</goal>
            </goals>
            <phase>package</phase>
            <inherited>true</inherited>
            <configuration>
              <archive>target/${project.build.finalName}.apk</archive>
              <arguments>
                <argument>-sigalg</argument>
                <argument>MD5withRSA</argument>
                <argument>-digestalg</argument>
                <argument>SHA1</argument>
              </arguments>
              <sigfile>CERT</sigfile>
              <keystore>${env.HOME}/.keystore</keystore>
              <storepass>${env.KEY_STOREPASS}</storepass>
              <keypass>${env.KEY_KEYPASS}</keypass>
              <alias>${env.KEY_ALIAS}</alias>
            </configuration>
          </execution>
        </executions>
      </plugin>

You don't use Maven? Your loose, it is the best way to develop Android. And it is just not my opinion: ViewpageIndicator, AndroidAnnotations, Robotium — All the top Android developers use Maven.
