Main use cases

- * - *

These are the main use cases that drove the design of this library

- * - *
    - *

  1. Annotate an existing dex file - In this case, the intent is to document the structure of - * an existing dex file. We want to be able to read in the dex file, and then write out a dex file - * that is exactly the same (while adding annotation information to an AnnotatedOutput object)

    2. - * - *

  2. Canonicalize an existing dex file - In this case, the intent is to rewrite an existing dex file - * so that it is in a canonical form. There is a certain amount of leeway in how various types of - * tems in a dex file are ordered or represented. It is sometimes useful to be able to easily - * compare a disassebled and reassembled dex file with the original dex file. If both dex-files are - * written canonically, they "should" match exactly, barring any explicit changes to the reassembled - * file.

    - * - *

    Currently, there are a couple of pieces of information that probably won't match exactly - *

      - *
    • the order of exception handlers in the EncodedCatchHandlerList for a method
      • - *
    • the ordering of some of the debug info in the {@link org.jf.dexlib.DebugInfoItem} for a method
      • - *

    - * - * - *

    Note that the above discrepancies should typically only be "intra-item" differences. They - * shouldn't change the size of the item, or affect how anything else is placed or laid out

    3. - * - *

  3. Creating a dex file from scratch - In this case, a blank dex file is created and then classes - * are added to it incrementally by calling the {@link org.jf.dexlib.Section#intern intern} method of - * {@link DexFile#ClassDefsSection}, which will add all the information necessary to represent the given - * class. For example, when assembling a dex file from a set of assembly text files.

    - * - *

    In this case, we can choose to write the dex file in a canonical form or not. It is somewhat - * slower to write it in a canonical format, due to the extra sorting and calculations that are - * required.

    4. - * - * - *

  4. Reading in the dex file - In this case, the intent is to read in a dex file and expose all the - * data to the calling application. For example, when disassembling a dex file into a text based - * assembly format, or doing other misc processing of the dex file.

    5. - * - * - *

    Other use cases

    - * - *

    These are other use cases that are possible, but did not drive the design of the library. - * No effort was made to test these use cases or ensure that they work. Some of these could - * probably be better achieved with a disassemble - modify - reassemble type process, using - * smali/baksmali or another assembler/disassembler pair that are compatible with each other

    Main use cases

    + * + *

    These are the main use cases that drove the design of this library

    + * + *
      + *

    1. Annotate an existing dex file - In this case, the intent is to document the structure of + * an existing dex file. We want to be able to read in the dex file, and then write out a dex file + * that is exactly the same (while adding annotation information to an AnnotatedOutput object)

      2. + * + *

    2. Canonicalize an existing dex file - In this case, the intent is to rewrite an existing dex file + * so that it is in a canonical form. There is a certain amount of leeway in how various types of + * tems in a dex file are ordered or represented. It is sometimes useful to be able to easily + * compare a disassebled and reassembled dex file with the original dex file. If both dex-files are + * written canonically, they "should" match exactly, barring any explicit changes to the reassembled + * file.

      + * + *

      Currently, there are a couple of pieces of information that probably won't match exactly + *

        + *
      • the order of exception handlers in the EncodedCatchHandlerList for a method
        • + *
      • the ordering of some of the debug info in the {@link org.jf.dexlib.DebugInfoItem} for a method
        • + *

      + * + * + *

      Note that the above discrepancies should typically only be "intra-item" differences. They + * shouldn't change the size of the item, or affect how anything else is placed or laid out

      3. + * + *

    3. Creating a dex file from scratch - In this case, a blank dex file is created and then classes + * are added to it incrementally by calling the {@link org.jf.dexlib.Section#intern intern} method of + * {@link DexFile#ClassDefsSection}, which will add all the information necessary to represent the given + * class. For example, when assembling a dex file from a set of assembly text files.

      + * + *

      In this case, we can choose to write the dex file in a canonical form or not. It is somewhat + * slower to write it in a canonical format, due to the extra sorting and calculations that are + * required.

      4. + * + * + *

    4. Reading in the dex file - In this case, the intent is to read in a dex file and expose all the + * data to the calling application. For example, when disassembling a dex file into a text based + * assembly format, or doing other misc processing of the dex file.

      5. + * + * + *

      Other use cases

      + * + *

      These are other use cases that are possible, but did not drive the design of the library. + * No effort was made to test these use cases or ensure that they work. Some of these could + * probably be better achieved with a disassemble - modify - reassemble type process, using + * smali/baksmali or another assembler/disassembler pair that are compatible with each other
