Android emulator won't mount SD card -


i'm running virtual machine in android studio. problem is never mounting sd card. in settings, i've tried studio-managed (100mb) creating 1 myself:

$ ./mksdcard -l sdcard 100m sdcard.img

the file in home folder r/w rights.

this configuration:

avd.ini.encoding=utf-8 avdid=devicec_api_17 playstore.enabled=false abi.type=x86 avd.ini.displayname=devicec api 17 disk.datapartition.size=800m hw.accelerometer=no hw.audioinput=yes hw.battery=yes hw.camera.back=emulated hw.camera.front=emulated hw.cpu.arch=x86 hw.cpu.ncore=4 hw.dpad=no hw.device.manufacturer=user hw.device.name=devicec hw.gps=no hw.gpu.enabled=yes hw.gpu.mode=auto hw.initialorientation=landscape hw.keyboard=yes hw.lcd.density=160 hw.mainkeys=no hw.ramsize=1536 hw.sdcard=yes hw.sensors.orientation=no hw.sensors.proximity=no hw.trackball=no image.sysdir.1=system-images/android-17/google_apis/x86/ runtime.network.latency=none runtime.network.speed=full sdcard.path=/home/user/sdcard.img showdeviceframe=no skin.dynamic=yes skin.name=800x600 skin.path=_no_skin skin.path.backup=_no_skin tag.display=google apis tag.id=google_apis vm.heapsize=48

as can see, hw.sdcard set yes.

honestly don't know in logcat. filtering mount saw this:

i've tried running in command line:

$ ./emulator -avd casio_api_17 -sdcard /home/mariano/sdcard.img

but don't see error. sd card won't mount.

this seems issue recent emulator version, possibly in relation older android versions (jelly bean, etc.).

downgrading sdk tools previous version solves issue.

it works example r25.2.5, can download windows, linux, or mac os x. if store tools outside of original sdk directory may need set android_sdk_root environment variable.

then use emulator executable shipped package start avd:

$ ./emulator -avd casio_api_17 -sdcard /home/mariano/sdcard.img

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
