问题
Is there a way that I can access the other sim in my android? I have an android Cherry Mobile Orbit which is a dual sim android phone. I want to develop an SMS application for my phone, but only the 1st sim will be access. I want to access the other sim, so that when i press enter to send the message, there will be a prompt, that which sim the message will be sent. I know that it's propreitary, but the phone manufacturer has no feedback about it. Is there any other way? tweaking or something?
回答1:
I think you can use dex2jar or apktool to reverse those app which runs on dual sim card devices, once you found the related "service manager", "telephony manager",some interface stub, or some key words like "Gemini" you can then use Java Reflection, reflects all of method of this class. Then you can achieve this goal.

Officially right now there is no API to support this, you have to contact the device manufacturer.

Assuming that you are developing the app for your own phone, and you are willing to go through the trouble of finding out the IDs (sim_id) assigned to each of your SIM cards (probably via checking the phone's log outputs, searching for sim_id, which was what I did), you can use the following code to set the default SIM for SMS sending:
int simId = <place desired SIM ID here>;
Intent simIntent = new Intent("android.intent.action.SMS_DEFAULT_SIM");
simIntent.putExtra("simid", simId);
sendBroadcast(simIntent);
Combined with some other UI prompt stuff (for actually 'picking' the preferred SIM), this should do the trick.
I'm not at all sure if this approach would work for you (although the code seems quite 'standard'); I figured it out with trial and error on my Mlais MX28 (with a customized ROM). But it's still worth a shot, I suppose. :)
UPDATE:
Strangely, the solution stopped working unexpectedly after a few updates to the app I was working on. But I came across another way (which seems to be more promising). (I believe this can be extended for other SIM selection scenarios as well, as the settings cache contains entries with names gprs_connection_sim_setting, voice_call_sim_setting, video_call_sim_setting and the like.)
ContentValues val = new ContentValues();
val.put("value", "here goes the preferred SIM ID");
getContentResolver().update(Uri.parse("content://settings/system"), val, "name='sms_sim_setting'", null);
(Unfortunately, this requires the android.permission.WRITE_SETTINGS permission.)
