[Soot-list] Why the version of android.jar is changed during the processing of FlowDroid on the same app?

[Jin Li]

Hi, All

I found a very strange error that the version of android.jar that needed in
the analysis is changed.

The apk use android-18 as target sdk
<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

The corresponding output as follows.  FlowDroid use ...\android-18\android.jar
as android.jar in the previous analysis, however it use
...\android-17\android.jar'
as android.jar in the last analysis, which reslults an error.

com.example.asyncleakdemo.MainActivity
