| 18 | Signs all the APK files in a target-files zipfile, producing a new |
| 19 | target-files zip. |
| 20 | |
| 21 | Usage: sign_target_files_apks [flags] input_target_files output_target_files |
| 22 | |
| 23 | -s (--signapk_jar) <path> |
| 24 | Path of the signapks.jar file used to sign an individual APK |
| 25 | file. |
| 26 | |
| 27 | -e (--extra_apks) <name,name,...=key> |
| 28 | Add extra APK name/key pairs as though they appeared in |
| 29 | apkcerts.zip. Option may be repeated to give multiple extra |
| 30 | packages. |
| 31 | |
| 32 | -k (--key_mapping) <src_key=dest_key> |
| 33 | Add a mapping from the key name as specified in apkcerts.txt (the |
| 34 | src_key) to the real key you wish to sign the package with |
| 35 | (dest_key). Option may be repeated to give multiple key |
| 36 | mappings. |
| 37 | |
| 38 | -d (--default_key_mappings) <dir> |
| 39 | Set up the following key mappings: |
| 40 | |
| 41 | build/target/product/security/testkey ==> $dir/releasekey |
| 42 | build/target/product/security/media ==> $dir/media |
| 43 | build/target/product/security/shared ==> $dir/shared |
| 44 | build/target/product/security/platform ==> $dir/platform |
| 45 | |
| 46 | -d and -k options are added to the set of mappings in the order |
| 47 | in which they appear on the command line. |
