telephonymanager

问题 I'm applying Android 6.0 runtime permissions into an app which listens to carrier data connection state changes. I first tried to just remove the READ_PHONE_STATE from the manifest to check where the app requires the permission. To my surprise the app didn't crash at all. After this I've tried the same installation on two pre 6.0 devices which did actually crash on it. To me it seems like Android 6.0 does no longer require the permission. Is there any way to confirm this? The line below is

问题 I am creating an android application in which I need to detect the target sim for an incoming call in dual sim phone. The Android API provides the access of only one SIM. I did googling about this but couldn't find the solution, All I found is that we can not detect the target SIM because this is depend upon the device manufactures. Is there any API available to detect the target SIM ? 回答1: in lollipop 22+ public class MessageReceiver extends BroadcastReceiver { @Override public void

问题 My app uses the TelephonyManager.ACTION_PHONE_STATE_CHANGED for some actions. But I want a different action while the phone rang when the user was present (screen was on) and different action when the user was not present (screen was off). I tried the isScreenOn() method just in the beginning of onReceive (because when screen is off and there is incoming call, the screen stays off for a short while). No luck however - sometimes it works, sometimes not. The broadcast is asynchronous with the

Also I think that it should be possible to poll the CellID of the current Base Station instead of having to listen to State Changes to determine int

问题 In Android (target 25) I have a background service and in onCreate function I have initialized a phone state listener. It works fine on Android versions that are before Nougat but in Nougat it doesn't work, even though the permissions are granted. public class Service extends IntentService { class PhoneListener extends PhoneStateListener { String TAG = getClass().getName(); @Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state,
