E/AndroidRuntime(14713): java.lang.RuntimeException: Unable to instantiate application com.android.mms.MmsApp: java.lang.ClassNotFoundException: Didn't find class "com.android.mms.MmsApp" on path: DexPathList[[zip file "/system/priv-app/SecMms_Candy/SecMms_Candy.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

In this block of stuff is the full error, but the line above is the major reason that it's failing.I see you've tried renaming the app, but have you modified the manifest? If not, the names will not match throwing this error.
