Background
I know that we can get the network usage (total bandwidth used of mobile&Wifi so far, from some specific time) of a specified app by using something like that (asked in the past, here) :
private final static int[] NETWORKS_TYPES = new int[]{ConnectivityManager.TYPE_WIFI, ConnectivityManager.TYPE_MOBILE};
long rxBytes=0L, txBytes=0L;
final TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
final String subscriberId = telephonyManager.getSubscriberId();
final ApplicationInfo applicationInfo = context.getPackageManager().getApplicationInfo(packageName, 0);
final int uid = applicationInfo.uid;
for (int networkType : NETWORKS_TYPES) {
final NetworkStats networkStats = networkStatsManager.queryDetailsForUid(networkType, subscriberId, 0, System.currentTimeMillis(), uid);
final Bucket bucketOut = new Bucket();
while (true) {
networkStats.getNextBucket(bucketOut);
final long rxBytes = bucketOut.getRxBytes();
if (rxBytes >= 0)
totalRx += rxBytes;
final long txBytes = bucketOut.getTxBytes();
if (txBytes >= 0)
totalTx += txBytes;
if (!networkStats.hasNextBucket())
break;
}
}
}
Docs:
https://developer.android.com/reference/android/app/usage/NetworkStatsManager.html#queryDetailsForUid(int,%20java.lang.String,%20long,%20long,%20int)
It's also possible to get the global network usage (using TrafficStats.getUidRxBytes(applicationInfo.uid) and TrafficStats.getUidTxBytes(applicationInfo.uid) ), but that's not what this thread is all about.
The problem
It seems Android Q is planned to cause a lot of device-identity functions to stop working anymore, and getSubscriberId is one of them.
What I've tried
I tried to set the targetSdk to 29 (Q) and see what happens when I try to use this.
As expected, I got an exception that shows me that I can't do it anymore. It says :

Searching the Internet and here, I don't see this mentioned, but I have found about similar issues, of getting IMEI and other identifiers:
- I am getting IMEI null in Android Q?
- https://issuetracker.google.com/issues/130202003
- https://issuetracker.google.com/issues/129583175
- https://developer.android.com/preview/privacy/data-identifiers#device-ids
So for now I just made a bug report about it here (including a sample project) :
https://issuetracker.google.com/issues/134919382
The question
Is it possible to get network usage of a specified app on Android Q (when targeting to it) ? Maybe without subscriberId?
If so, how?
If not, is it possible by having root, or via adb?
EDIT:
OK, I don't know how to officially use this, but at least for root access it is possible to get the subscriberId, using this solution, found from here.
Meaning something like that:
@SuppressLint("MissingPermission", "HardwareIds")
fun getSubscriberId(telephonyManager: TelephonyManager): String? {
try {
return telephonyManager.subscriberId
} catch (e: Exception) {
}
val commandResult = Root.runCommands("service call iphonesubinfo 1 | grep -o \"[0-9a-f]\\{8\\} \" | tail -n+3 | while read a; do echo -n \"\\u\${a:4:4}\\u\${a:0:4}\"; done")
val subscriberId = commandResult?.getOrNull(0)
return if (subscriberId.isNullOrBlank()) null else subscriberId
}
It's not an official solution, of course, but it's better than nothing...
EDIT: the part of getting it via root is wrong. It doesn't help in any way.
