I am trying to rebuild an Android 'framework.jar' from a 'framework.odex' file.

The ODEX file has been obtained using an Android terminal emulator of the Android SDK, emulating an Android v22 platform.

The ODEX file has been converted into a DEX file using baksmali and smali V2.0.3 to produce a framework.dex file.

I'm using dex-2-jar V2.1 nightly build #43.

I get the following error:

-- Landroid/preference/MultiSelectListPreference$1;.onClick(Landroid/content/DialogInterface;IZ)
V java.lang.RuntimeException: can not merge I and Z
--

The summary error file contains this:

    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)
