Hi Peter,

That issue should be fixed now. Please update Soot.

Best regards,

  Steven

Betreff: Re: [Soot-list] (no subject)

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.

Hi,

When I run FlowDroid on an app (whose APK is here: https://drive.google.com/file/d/0B9KLXcAovVUHRVdaM0t1R01BaHM/view?usp=sharing), I get the following error. I'm using recent version of Soot (February 25, 2015) and FlowDroid (February 23, 2015). This issue also seems to have been raised elsewhere (Issue #358 in Github, Sable/Soot, type of throw statement is bottom_type when it should be an actual type). Do you know how I can get around this problem? Thanks.

Exception in thread "main" java.lang.IllegalStateException: UnitThrowAnalysis StmtSwitch: type of throw argument is not a RefType! It seems that the type of the processed throw statement is bottom_type instead of an actual type
