Example 24 with DexFile

use of org.jf.dexlib2.iface.DexFile in project smali by JesusFreke.

the class DexInputCommand method loadDexFile.

/**
     * Parses a dex file input from the user and loads the given dex file.
     *
     * In some cases, the input file can contain multiple dex files. If this is the case, you can refer to a specific
     * dex file with a slash, followed by the entry name, optionally in quotes.
     *
     * If the entry name is enclosed in quotes, then it will strip the first and last quote and look for an entry with
     * exactly that name. Otherwise, it will perform a partial filename match against the entry to find any candidates.
     * If there is a single matching candidate, it will be used. Otherwise, an error will be generated.
     *
     * For example, to refer to the "/system/framework/framework.jar:classes2.dex" entry within the
     * "framework/arm/framework.oat" oat file, you could use any of:
     *
     * framework/arm/framework.oat/"/system/framework/framework.jar:classes2.dex"
     * framework/arm/framework.oat/system/framework/framework.jar:classes2.dex
     * framework/arm/framework.oat/framework/framework.jar:classes2.dex
     * framework/arm/framework.oat/framework.jar:classes2.dex
     * framework/arm/framework.oat/classes2.dex
     *
     * The last option is the easiest, but only works if the oat file doesn't contain another entry with the
     * "classes2.dex" name. e.g. "/system/framework/blah.jar:classes2.dex"
     *
     * It's technically possible (although unlikely) for an oat file to contain 2 entries like:
     * /system/framework/framework.jar:classes2.dex
     * system/framework/framework.jar:classes2.dex
     *
     * In this case, the "framework/arm/framework.oat/system/framework/framework.jar:classes2.dex" syntax will generate
     * an error because both entries match the partial entry name. Instead, you could use the following for the
     * first and second entry respectively:
     *
     * framework/arm/framework.oat/"/system/framework/framework.jar:classes2.dex"
     * framework/arm/framework.oat/"system/framework/framework.jar:classes2.dex"
     *
     * @param input The name of a dex, apk, odex or oat file/entry.
