[android-developers] BluetoothServerSocket.accept
I am trying to write a Bluetooth android application. I have used many
ideas from the samples and the bluetooth page in the android developers
site.
So, I put up a dialog that has the available bluetooth devices available,
there is only one, and when I pick it the dialog goes to a method to manage
the results of the dialog.
What I want to do is spawn a thread from this method that sits on a call
that blocks. I have the Thread and everything seems good, except the
dialog won't go away until the thread has been cancelled. But I can't
cancel it because I am stuck in a blocking dialog.
I have tried to create a Broadcast receiver to send myself a message,
hoping the dialog goes away before I get the message, but that doesn't work
either, the dialog still blocks until I remove it with a new instance that
doesn't fork the thread.
The question is, is there a good way to delay the thread running until the
dialog is down, whenever that is? Or is what I am doing supposed to work
and I have something else wrong.
//The dialog basically unchanged from the sample
public Dialog onCreateDialog(Bundle savedInstanceState) {
String[] deviceNames = getArguments().getStringArray("names");
int position = getArguments().getInt("position", -1);
if (position == -1) position = 0;
return new AlertDialog.Builder(getActivity())
.setTitle(R.string.select_device)
.setPositiveButton(R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
which) {
((BrewActivity)
getActivity()).connectChannel();
}
})
.setSingleChoiceItems(deviceNames, position,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
which) {
((BrewActivity)
getActivity()).setDevice(which);
}
}
)
.create();
}
}
//The connect channel method where I send myself the message
private void connectChannel() {
Log.w(TAG, "Connect Channel.");
mConnectIndicator.setText(mRes.getString(R.string.connected));
mDataIndicator.setImageLevel(1);
Intent intent = new Intent();
intent.setAction("madigan.android.action.CONNECT");
sendBroadcast(intent);
}
//The broadcast receiver that gets the message I send myself.
private final BroadcastReceiver mConnector = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.w(TAG, "Connect Receiver.");
final String action = intent.getAction();
if (action.equals("madigan.android.action.CONNECT" ) ){
connect();
}
}
};
// The method called with the success of the broadcast
private void connect() {
Log.w(TAG, "Connect.");
// Starts connection Thread.
AcceptThread aThread = new AcceptThread();
aThread.run();
BluetoothServerSocket socket = connectDevice(mBluetoothAdapter,
mDevice);
try {
socket.accept();
}
catch(IOException e){
Log.w(TAG, "Accept with Exception.");
}
Log.w(TAG, "Accept with No Exception.");
}
// and finally the thread
private class AcceptThread extends Thread {
private final BluetoothServerSocket mmServerSocket;
public AcceptThread() {
// Use a temporary object that is later assigned to
mmServerSocket,
// because mmServerSocket is final
BluetoothServerSocket tmp = null;
try {
// MY_UUID is the app's UUID string, also used by the
client code
tmp =
mBluetoothAdapter.listenUsingInsecureRfcommWithServiceRecord(mDevice.getName(),
UUID.randomUUID());
} catch (IOException e) { }
mmServerSocket = tmp;
}
public void run() {
BluetoothSocket socket = null;
// Keep listening until exception occurs or a socket is returned
while (true) {
try {
socket = mmServerSocket.accept();
} catch (IOException e) {
break;
}
// If a connection was accepted
if (socket != null) {
// Do work to manage the connection (in a separate
thread)
manageConnectedSocket(socket);
try {
mmServerSocket.close();
}
catch (IOException e){
break;

Dan,
I literally just worked through this error — mine was caused by adding the
Facebook SDK as a module dependency to a project in the latest version of
Android Studio. In my case, I saw a stack trace very similar to yours, but the
actual exception was further upstream, and the error was due to the fact that
the Facebook SDK uses a different version of the android support jar than my
primary project. I had to go into the Facebook SDK’s build.gradle file and
comment out its jar and use the other one that my primary project was using, as
follows:
dependencies {
//compile files('libs/android-support-v4.jar')
compile 'com.android.support:support-v4:18.0.0'
}
After fixing that, all problems disappeared. I don’t know if this is going to
help you even a little, but I’ve spent the day stumbling around in the spooky
Halloween land of undocumented tools and APIs, and thought I’d at least try to
lend a hand. Good luck, and let me know if you are able to make it through.
Cheers,
Brad

Re: [android-developers] Bluetooth connection
It seems that something like this would do the trick: http://www.miniinthebox.com/bluetooth-master-uart-board-wireless-transceiver-module-uart-interface-host-mode_p394547.html?currency=USD&litb_from=paid_adwords_shopping&gclid=CJbo1KSwwboCFdGe4AodKzQAzQ It's got a UART interface and lets you stick raw bytes, I'd assume.

Re: [android-developers] Simulating tens of thousands of android devices
Mukesh is right on this one. Stress testing your server won't be any different than testing any other sort of server. Just create a dummy that simulates what an Android device would do and throw thousands of requests at it. Ideally, if you're using some sort of service (e.g., Rails) you should Google how to test that type of thing and then do whatever it says.

[android-developers] TextUtils and DateUtils Stubed ?
Hi folks, I noticed that TextUtils and DateUtils are stubbed in the SDK (all theirs methods return a RuntimeException with the label "Stub!").

you could easily go with the load and stress test and it need not be on only from Mobile devices... :( any ways, to test the client and server, you could go with the following link. http://jmeter.apache.org/usermanual/jmeter_distributed_testing_step_by_step.pdf On Thu, Oct 31, 2013 at 12:24 PM, JavaSrvcs wrote: > I would like to know or explore ways to simulate tens of thousands of real > world devices hitting my server. > > I am interesting in things like sending GPS data per device (within a > region) such that device info is coming from geographic parameters I can > program. > I am also interested in simulating various battery level strength, wifi > signal strength and other parameters that can be gathered from an android > device. > > If there is a way to create a very low foot print virtualized android > device that would send this info, please let me know, I would need the > ability to run a simulation of a thousand devices per 8 core/64GB box if > possible, simulating various virtualized devices of a good mix of android > releases. > > -- > You received this message because you are subscribed to the Google > Groups "Android Developers" group. > To post to this group, send email to android-developers@googlegroups.com > To unsubscribe from this group, send email to > android-developers+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/android-developers?hl=en > --- > You received this message because you are subscribed to the Google Groups > "Android Developers" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to android-developers+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/groups/opt_out. > -- Warm Regards, *Mukesh Kumar*, Android Consultant/Freelancer, India,Hyderabad. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
