I am just running FlowDroid in the standard way, with the first argument as
"freegemas-android.apk" and second argument as "android.jar". BUT the
jimple body is correct (RefType) when I use the stub android.jar, and
incorrect (bottom_type) when I use the full android.jar (
http://repository.grepcode.com/java/ext/com/google/android/android/4.4.2_r1/android-4.4.2_r1.jar
):

<CORRECT Jimple when using stub android.jar>
void resume() {
        com.badlogic.gdx.backends.android.AndroidGraphics $r0;
        java.lang.Object $r1;
        java.lang.Throwable $r2;

        $r0 := @this: com.badlogic.gdx.backends.android.AndroidGraphics;
        $r1 = $r0.<com.badlogic.gdx.backends.android.AndroidGraphics:
java.lang.Object synch>;
        entermonitor $r1;

     label1:
        $r0.<com.badlogic.gdx.backends.android.AndroidGraphics: boolean
running> = 1;
        $r0.<com.badlogic.gdx.backends.android.AndroidGraphics: boolean
resume> = 1;
        exitmonitor $r1;

     label2:
        return;
}

<INCORRECT Jimples when using full android.jar>
void resume() {
        com.badlogic.gdx.backends.android.AndroidGraphics $r0;
        bottom_type $r1;
        java.lang.Object $r2;

        $r0 := @this: com.badlogic.gdx.backends.android.AndroidGraphics;
        $r2 = $r0.<com.badlogic.gdx.backends.android.AndroidGraphics:
java.lang.Object synch>;
        entermonitor $r2;

        $r0.<com.badlogic.gdx.backends.android.AndroidGraphics: boolean
running> = 1;
        $r0.<com.badlogic.gdx.backends.android.AndroidGraphics: boolean
resume> = 1;
        exitmonitor $r2;

        return;

        throw $r1;
}

The problem is that I want to use the full android.jar. Do you know how to
solve this problem? Thanks.
