invoke-interface { v1, v2 }, Ljava/util/Set;->add(Ljava/lang/Object;)Z
move-result v1
invoke-static { v0, v1 },  // v1 is boolean but used as integer
             Landroid/preference/MultiSelectListPreference;->access$076(Landroid/preference/MultiSelectListPreference;I)Z

the problem is caused by strict type calculation, because in java syntaxt, a boolean can not assign to an inteager. so dex2jar forbid merge type Z and I. It is simple to fix

• modify the dex by hand and add the following code after move-result v1

if-eqz v1, :LZERO
    const v1, 1
    goto :Lend
:LZERO
    const v1, 0
:Lend

• OR modify the dex2jar code. return Type I when merge I and Z at com.googlecode.dex2jar.ir.TypeClass.merge(TypeClass.java:100)
