How to Send and Receive Messages Android Wear

I'm trying to send String from my Moto 360 to Android App! but I don't understand how to implement the code in documentation, can anyone help me please with a little explanation of the steps to follow to send data !
http://developer.android.com/training/wearables/data-layer/messages.html

Take a look at a samples, this line exactly shows how to send a message:
http://developer.android.com/samples/DataLayer/Application/src/com.example.android.wearable.datalayer/MainActivity.html#l335
private void sendStartActivityMessage(String node) {
Wearable.MessageApi.sendMessage(
mGoogleApiClient, node, START_ACTIVITY_PATH, new byte[0]).setResultCallback(
new ResultCallback<SendMessageResult>() {
#Override
public void onResult(SendMessageResult sendMessageResult) {
if (!sendMessageResult.getStatus().isSuccess()) {
Log.e(TAG, "Failed to send message with status code: "
+ sendMessageResult.getStatus().getStatusCode());
}
}
}
);
}
If that's too much information, a simpler tutorial for MessageApi should be just a google search away. Try this one: http://www.binpress.com/tutorial/a-guide-to-the-android-wear-message-api/152 it looks reasonable.

How to get Tweets from Twitter of perticular User in Android ?(Want to show tweets(Done by signin User) in my list view)

I am integrating Twitter with my android Application for that I am using Twitter4j 3.0.3. till now everything is fine I have completed composing new Tweet,Upload Image,change profile picture. Now I want to show Tweets(composed by Signin User) .

I tried to find out solution but I have found same solution everywhere like

same issue like mine
they have shown the solution but I cant figure out where should I change in my code?
So I need one good example for Showing Tweets(which is done by User)in list view I have tried most examples as shown above, but I am getting error Invalid cookie
header: so please explain me in detail how should I fix these error?

I get Answer of My Question :)
Here it is .. :)
btn_getTweets.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tweets_list.clear();
TwitterLogin.mTwitter.getUserTweets();
if(tweets_list.size()==0)
{
Toast.makeText(getApplicationContext(),"You haven't tweeted yet.", Toast.LENGTH_SHORT).show();
}
else
{
tweetsAdapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,tweets_list);
listView.setAdapter(tweetsAdapter);
}
}
});
where TwitterLogin.mTwitter class has store my Credentials.
and TwitterLogin.mTwitter.getUserTweets() is method is in other class Like
public void getUserTweets(){
System.out.println("Showing public timeline.");
try {
List<Status> statuses = mTwitter.getUserTimeline();
for (Status status : statuses) {
System.out.println(status.getUser().getName() + ":"
+ status.getText());
ComposeTwit.tweets_list.add(""+ status.getText());
}
Log.d("tweets_list Size", ""+ComposeTwit.tweets_list.size());
} catch (TwitterException te) {
System.out.println("Failed to get timeline: "
+ te.getMessage());
System.exit(-1);
}
}

Error integrating Aurasma: Resource Integrity check failed

I am trying to Integrating Aurasma in my application. All application work well but on Aurasma part when I launch it on Button Click IT throws a message on splash screen as "An error is occurred" and on Log Cat It shows "Resource integrity check failed" I am wondering why this is happening, I integrate aurasma on a separate application without any click event, it launches directly then it works but in side of my application its not working, why. I am sure about these points:
Make sure the SDK tools are version 14 or above.
Check the Eclipse project to make sure that AurasmaKernel is set as required on the build path
Check that the AurasmaKernel package has built properly in Eclipse (also try building it manually)
Make sure that the kernel is correctly extracted, and that your resources don't clash with any of the packaged library
But yet it not working same error message.
Code for launching Aurasma is below:
aurasmaIntent = AurasmaIntentFactory.getAurasmaLaunchIntent(HomeActivity.this,
getString(R.string.app_name), getString(R.string.app_version));
} catch (AurasmaLaunchException e) {
Log.e("AKTest", "Error getting intent", e);
showDialog(DIALOG_ERROR);
return;
}
if (DELAY_START) {
AurasmaSetupCallback callback = new AurasmaSetupCallback() {
#Override
public void onLoaded() {
dismissDialog(DIALOG_PROGRESS);
startActivity(aurasmaIntent);
}
#Override
public void onLoadWarning(final int code) {
Log.w("AKTest", "Preload warning: " + code);
}
#Override
public void onLoadFail(final int code) {
Log.e("AKTest", "Preload error: " + code);
dismissDialog(DIALOG_PROGRESS);
showDialog(DIALOG_ERROR);
}
};
showDialog(DIALOG_PROGRESS);
AurasmaIntentFactory.startAurasmaPreload(getApplicationContext(), aurasmaIntent,
callback);
} else {
startActivity(aurasmaIntent);
}
}

If you change some resource from Aurasma library(layout or string) you will get this error - "An error is occurred". Library checks resources on Aurasma start. Don't change or delete any files.
Another thing that can cause error is:
aurasmaIntent = AurasmaIntentFactory.getAurasmaLaunchIntent(HomeActivity.this,
getString(R.string.app_name), getString(R.string.app_version));
Here second parameter is userAgentName. This is the name of your app that you have from studio.aurasma.com. In "Make your own app" you can see the application name - this name is connected with your application but can be different.

check your minSdkVersion in the manifest
android:minSdkVersion="8"

Android: Monitoring Bluetooth Discovery - what does this compile error mean?

I'm learning Bluetooth programming on Android using the Wrox Professional Android 2 Application Development book. The discovery monitor example (pg 432) has this code snippet:
BroadcastReceiver discoveryMonitor = new BroadcastReceiver() {
String dStarted = BluetoothAdapter.ACTION_DISCOVERY_STARTED;
String dFinished = BluetoothAdapter.ACTION_DISCOVERY_FINISHED;
#Override
public void onReceive(Context context, Intent intent) {
if (dStarted.equals(intent.getAction())) {
// Discovery has started.
Toast.makeText(getApplicationContext(),
"Discovery Started...", Toast.LENGTH_SHORT).show();
}
else if (dFinished.equals(intent.getAction())) {
// Discovery has completed.
Toast.makeText(getApplicationContext(),
"Discovery Completed...", Toast.LENGTH_SHORT).show();
}
}
};
registerReceiver(discoveryMonitor,
new IntentFilter(dStarted));
registerReceiver(discoveryMonitor,
new IntentFilter(dFinished));
... and on each of the two registerReceiver calls at the end I get . . .
Syntax error on tokens, AnnotationName expected instead
Syntax error, insert "Type VariableDeclaratorId" to complete FormalParameterList
What's an annotationName and what's going wrong here?
Thanks in advance!!

Your problem is that you defined variables dStarted and dFinished as locals for discoveryMonitor BroadcastReceiver,
That way, you can't use them in registerReceiver(...)
You have to define them as global, or use
registerReceiver(discoveryMonitor, new
IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_STARTED));
instead.

Android - onClick errors in SMS app

I have a button that sends message - however the onClick feature in the onClickListener seems to give me a few errors when I tell it to disable the button when click, AND when I set toast to it. Oh, and the error underlines 'else' saying syntax error. (Other than that the code works fine and sends the SMS)
public void onClick(View v)
{
messageinfo mi = new messageinfo();
String message = txtMessage.getText().toString();
if (message.length()>0)
sendSMS(mi.SMSNO(), smsmessage);
Toast.makeText(getBaseContext(), "sending", Toast.LENGTH_SHORT).show();
myButton.setEnabled(false);
else
Toast.makeText(getBaseContext(), "enter your message", Toast.LENGTH_SHORT).show();
}
Is there an easy solution to this?

Through formatting your code I've noticed that it would appear that your if statement is failing.
You need to have { }s around the resulting code from an if statement, eg:
if(true){
line 1;
line 2;
line 3;
}
else {
line 1;
line 2;
line 3;
}
The only time you can miss out the { }s is when you've only got ONE statement following an if. This is always a bad idea however, its not much effort just to put in some { }s, and means that issues like this won't ever happen.
Clarification
The code in your question is running the if and if it matches it runs THE NEXT LINE. Then the code carries on OUTSIDE of the if clause (because of missing brackets)so then will run the next two lines REGARDLESS of the outcome of the if statement.
Then it encounters the else which its not expecting. Its supposed to be after either { .. } or directly after the FIRST statement after the if, so that's why it fails at the else.
