java - Error in just Samsung Galaxy S7 edge (maybe other unknown devices too) -


my project shared in this github link. though did run , test android app couple of devices successfully, there "stop working"/"keeps stop running" message in galaxy s7 edge. test cases sony xperia z3 , lg l70.

i tried send error message server via senderror service while catching exception in try/catch statement seems error out of statement , user(with s7 edge) reported problem has been existed.

so in general form, how can find what's wrong code while haven't got access specific device(which error occurs)? couldn't test app on every device(nor can buy s7 edge test app).

if saw code , chance know part causing happen, please notify me.

notice: error occurs in couple of seconds. guess happens in startactivity or mainactivity or versionupdate.

update: don't have log , can't use firebase crash reports because of sanctions.

a few things:

firstly, have sort of crash reporter embedded app? if not, recommend using firebase crash reports. way, can see crash reports , stack traces, device information, useful when app crashed due device-specific crash.

second, have complete crash log galaxy s7 edge? if so, please post here, impossible without details of crash

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
