Show Full Kernel Version and add mod version to Settings

Hey again

So after playing with the gingerbread leak, and seeing that samsung decided (so far, at least) to show the full kernel version in the "About Phone" menu in settings, I decided to fix it on normal vibrant froyo roms.

At the same time, I also added the CM style "mod version" string. Someone else (I forget who and when, and I sincerely apologize for that) attempted this before, but I don't know if they didn't finish, or if it just never took off, but regardless, I decided to add it too, lol. For developers, all you need to add to your build.prop is:

Code:

ro.modversion=Bionix-1.2.1

Obviously replace everything after the = with your personal mod version.
Anyway, to show the full kernel version string:
Decompile Settings.apk, open /smali/com/android/settings/DeviceInfoSettings.smali and replace the entire method "getFormattedKernelVersion" with the following code:

Code:

.method private getFormattedKernelVersion()Ljava/lang/String;
    .locals 11

    .prologue
    const/4 v8, 0x4

    const-string v6, "\n"

    const-string v9, "DeviceInfoSettings"

    :try_start_0
    new-instance v5, Ljava/io/BufferedReader;

    new-instance v6, Ljava/io/FileReader;

    const-string v7, "/proc/version"

    invoke-direct {v6, v7}, Ljava/io/FileReader;->(Ljava/lang/String;)V

    const/16 v7, 0x100

.end method

Then to add "Mod version" further down in the file, search for the following lines:

Code:

.line 74
    const-string v2, "kernel_version"

    invoke-virtual {p0, v2}, Lcom/android/settings/DeviceInfoSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;

    move-result-object v2

    invoke-direct {p0}, Lcom/android/settings/DeviceInfoSettings;->getFormattedKernelVersion()Ljava/lang/String;

    move-result-object v3

    invoke-virtual {v2, v3}, Landroid/preference/Preference;->setSummary(Ljava/lang/CharSequence;)V
    .line 77

and before the .line 77 add the following:

Code:

const-string v2, "mod_version"
const-string v3, "ro.modversion"
invoke-direct {p0, v2, v3}, Lcom/android/settings/DeviceInfoSettings;->setValueSummary(Ljava/lang/String;Ljava/lang/String;)V

Then add or change the following to /res/xml/device_info_settings.xml (I removed the "style="?android:preferenceInformationStyle" />" after Kernel version to ensure that it shows all three lines, since preferenceInformationStyle truncates at 2 lines by default)

Code:

and for the mod version, add the following to /res/values/strings.xml

Mod version
Unknown

and finally, declare the strings in /res/values/public.xml

Code:

    <public type="string" name="mod_version" id="0x7f090639" />
    <public type="string" name="mod_version_default" id="0x7f09063a" />

Please note, you might need to increment/decrement the last digit or two to fit with any other mods already present in your Settings.apk.
