getDependencies

public static java.lang.String[] getDependencies(java.lang.String soName,
                                                 java.io.File elfFile)

Throws:

java.io.IOException

getDependencies

                                                 ElfByteChannel bc)
                                          throws java.io.IOException

Throws:

java.io.IOException

useDepsFile

public static boolean useDepsFile(byte[] apkId,
                                  java.lang.String depsFilePath)
                           throws java.io.IOException

Enables fetching dependencies from a deps file and specifies the path to the deps file. If enabled, dependencies will be looked up in the deps file instead of extracting them from the ELF file. The file is read only once when getDependencies is first called. If dependencies for a specific library are not found or the file is corrupt, we fall back to extracting the dependencies from the ELF file.

Throws:

java.io.IOException
