t-vk / android-svc Goto Github PK

Hi there! I've tried to follow the demo with a Google Pixel (sailfish). The device is rooted via Magisk, android-svc was built from master, then I've downloaded the sources with android-svc --adb download.

All seems to be fine as far as I can tell:

root@debian11:~/tmp# ./android-svc --adb list-packages | grep IAudioService
android.media.IAudioService
root@debian11:~/tmp# ./android-svc --adb list-methods android.media.IAudioService | grep MasterMute
boolean isMasterMute();
void setMasterMute(boolean mute, int flags, String callingPackage, int userId);
root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.isMasterMute()'
false

But when I try to mute/unmute, nothing happens:

root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.setMasterMute(true, 0, "com.termux", 0)'
root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.isMasterMute()'
false

I've also tried something else:

root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.isSpeakerphoneOn()'
false
root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.setSpeakerphoneOn(true)'
root@debian11:~/tmp# ./android-svc --adb call 'android.media.IAudioService.isSpeakerphoneOn()'
false

Any ideas?

Just give an example to explain the format of printed parcel data

x1q:/ $ service call phone 69  s16 'shell' s16 ''
Result: Parcel(
  0x00000000: 00000000 00000001 00000001 00000003 '................'
  ****HIDDEN SOME DATA****
  0x000000a0: 00000000                            '....            ')

the first and last 00000000 seems the open and close tags of the content, therefore just skip these chunks.

then for the 00000001 00000001 00000003, the first 00000001 seems to indicate a successful call. Here the expected call return is List<CellInfo>, hence the second 00000001 is the length of the list.

Since the encoding is using little endian, the 00000001 should be reversed to 01000000 then the Parcel can use readInt() correctly, in this case val count = parcel.readInt() , count indicates how many element in the return list.

To decode the CellInfo , it should call CellInfo.Creator.readFromParcel(parcel) and depends on the count, it should be called multiple times to fully decode them all

android-svc download downloads all of AIDL files for the current android version,

But after it succeeded I requested
commands such as android-svc list-module and android-svc call, It seemed not to enter offline mode and still took long time to fetch data from Internet.

Is the offline mode broken? Or some configurations required?

Hi,

I'm starting implementing services functions for a adbkit fork project.
In the beginning, I just want to access the phone number of a phone using ADB.

but I want a clean implementation.

so I start to implement a service mapping code.

Maybe we can share some code (I'm using typescript, in my version).

Now I can list services, get the android version, the download the corrects aidl files from android git.

About the Parcel response, I extract all data as a buffer, convert big-endian to little-endian, and then read the response as UTF-16-LE (nodeJS do not support big-endian UTF-16).

TODO:

• Extract calls name + parameter from aidl files.
• Generate the helper code.
• Parse Parcel response.

Question:
How can I get the android minor revision. (for now I will check if all minor version are the same)

I found some interesting code here

Installed Termux and android-svc_0.1.0_all.deb on a LineageOS 17 rooted phone, but when I try to run android-svc download, it says "Permission denied".

~ $ android-svc download
Permission denied
Failed to retrieve Android version in GetAndroidVersion
