-in my AndroidManifest.xml I got the uses-permission I really dont know whats wrong any opinion is welcomed, It seems like the app is somehow skipping initializeSpeechRecognizer();. The app is only supposed to repeat what I said so thats why my processResult method contains only speak("command");
The problem was that my virtual device for some reason didn't cooperate with PC mic, on real machine it works.

as mentioned in this answer i guess GooglePlayServiceClient and has become outdated so remove it and use GoogleApiClientinstead.Also LocationServices.API, and FusedLocationProviderApi were introduced.
Usage of GoogleApiClient :
To use GoogleApiClient the first thing to change is the interface, the activity or service is implementing
//old code of GooglePlayServiceClient :
public class LocationMonitoringService extends Service implements GooglePlayServicesClient.ConnectionCallbacks
//replace the above ^ code with this: new code for GoogleApiClient
public class LocationMonitoringService extends Service implements GoogleApiClient.ConnectionCallbacks
in GooglePlayServiceClient, mLocationClient was just a regular class constructor.
inGoogleApiClient a Builder is used like :
//old code of GooglePlayServiceClient :
LocationClient mLocationClient;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mLocationClient = new LocationClient(this, this, this);
mLocationClient.connect();
}
replace it^ with new builder code of GoogleApiClient :
GoogleApiClient mLocationClient;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mLocationClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mLocationClient.connect();
}
Examples :
Requesting location :
Old code was just a simple call like
mLocationClient.requestLocationUpdates(mLocationRequest, locationListener);
in GoogleApiClient we use FusedLocatonApi like :
LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, locationListener);
This post shows you a implementation of most of the methods like :onConnected onConnectionFailed onConnectionSuspended etc.
May I ask why my onResume() DialogInterface keeps looping non stop? I have reference the onResume() from this website: http://pulse7.net/android/android-delete-sms-message-from-inbox-in-android/
#Override
protected void onResume() {
super.onResume(); int i=0;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
if(i==0) {
if (!Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName)) {
AlertDialog.Builder builder = new AlertDialog.Builder(ActivityMain_txt.this);
builder.setMessage("This app is not set as your default messaging app. Do you want to set it as default?")
.setCancelable(false)
.setTitle("Alert!")
.setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#TargetApi(19)
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, getPackageName());
startActivity(intent);
dialog.dismiss();
}
});
builder.show();
i++;}
}
}
But when I add this part of the code, the DialogInterface for "setPositiveButton" keeps looping non-stop. I am trying to set my application to become the default message application, so I will be able to delete messages. As now it is not set to become the default application, I am unable to delete any messages successfully. Any help will be deeply appreciated. Thanks in advance.

You are using the variable i as a flag, but whenever you open your app the value of i will be 0 again. You should store your flag in a persistent database. Either use SQLite to set i or use any other method like create a file when the user says yes to your question and then check if the file exists or not. If you don't understand what I've told you, I can send you some code snippets.
OK, I assume you are using i as a flag to check if user has set your app as default or not, so I suggest you to use SharedPreferences to store the value of i so that later on you can check the value of i in a better manner. Add the following code in your onResume function:
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
Instead of i++ use:
editor.putInt(i, 1);
editor.commit();
And to check if i==0 use:
int check =sharedprferences.getInt(i);

I am trying to accept BrainTree on my app. I don't understand the Async HTTP Client part.
Where do I place this in my app? Currently, I have it in the MainActivity and it is giving me errors for 'get', 'TextHttpResponseHandler' as well as 'clientToken'.
Any ideas?
package com.example.android.payments;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import com.loopj.android.http.*;
import com.braintreepayments.api.dropin.BraintreePaymentActivity;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://your-server/client_token", new TextHttpResponseHandler() {
#Override
public void onSuccess(String clientToken) {
this.clientToken = clientToken;
}
});
public void onBraintreeSubmit(View v) {
Intent intent = new Intent(context, BraintreePaymentActivity.class);
intent.putExtra(BraintreePaymentActivity.EXTRA_CLIENT_TOKEN, clientToken);
// REQUEST_CODE is arbitrary and is only used within this activity.
startActivityForResult(intent, REQUEST_CODE);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Your call to client.get() is not in a method body, so your code is not syntactically valid. Try putting it in a method (or constructor or initializer block - but it's a bad idea to do work in either of those places).
For example, you could put that statement in a new method called fetchClientToken():
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) { ... }
AsyncHttpClient client = new AsyncHttpClient();
public void fetchClientToken() {
client.get("https://your-server/client_token", new TextHttpResponseHandler() {
#Override
public void onSuccess(String clientToken) {
this.clientToken = clientToken;
}
});
}
public void onBraintreeSubmit(View v) { ... }
#Override public boolean onCreateOptionsMenu(Menu menu) { ... }
#Override public boolean onOptionsItemSelected(MenuItem item) { ... }
}
You then need to invoke fetchClientToken somehow, just like you would with any other method.
I am quite new to programming Android (7 months), and I am having a problem with creating an app.
What I am trying to do is create a "Person Detail" test app for my own Android learning, by having EditText on the Main Activity with TextViews next to them (displaying default values at first), open up another activity called EditData (with a button on the main) which displays the values the user entered into the EditText (via Parcelable), return back to the Main Activty (via another button) and have those entered values displayed in the TextViews next to the EditText (upon a "Update Info" button click) instead of the default ones. I have managed to get everything working right except for displaying the changed values. Everything checks out, no errors in LogCat, but when the user / I clicks the update button, what shows are the default values. Can someone help me?
Here is my Main Activity code:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
final Person firstPerson = new Person();
TextView displayName, displayAge, displayHeight, displayWeight;
EditText editName, editAge, editHeight, editWeight;
Button editActivity, update;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
instantiateUi();
editActivity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
firstPerson.setPersonName(editName.getText().toString());
firstPerson.setPersonAge(Integer.parseInt(editAge.getText().toString()));
firstPerson.setPersonHeight(Integer.parseInt(editHeight.getText().toString()));
firstPerson.setPersonWeight(Integer.parseInt(editWeight.getText().toString()));
Intent editIntent = new Intent(MainActivity.this, EditData.class);
editIntent.putExtra("First_Person_Data", firstPerson);
MainActivity.this.startActivity(editIntent);
}
});
update.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
displayName.setText(firstPerson.getPersonName());
displayAge.setText(String.valueOf(firstPerson.getPersonAge()));
// String.valueOf is needed to set int for TextViews
displayHeight.setText(String.valueOf(firstPerson.getPersonHeight()));
displayWeight.setText(String.valueOf(firstPerson.getPersonWeight()));
}
});
}
private void instantiateUi() {
editName = (EditText)findViewById(R.id.edit_name);
editAge = (EditText)findViewById(R.id.edit_age);
editHeight = (EditText)findViewById(R.id.edit_height);
editWeight = (EditText)findViewById(R.id.edit_weight);
displayName = (TextView)findViewById(R.id.display_name);
displayAge = (TextView)findViewById(R.id.display_age);
displayHeight = (TextView)findViewById(R.id.display_height);
displayWeight = (TextView)findViewById(R.id.display_weight);
editActivity = (Button)findViewById(R.id.edit_activity);
update = (Button)findViewById(R.id.update_info);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
}
My EditData activity code:
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class EditData extends ActionBarActivity {
TextView changedName, changedAge, changedHeight, changedWeight;
Button MainActivity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_activity);
Person incomingObject = getIntent().getParcelableExtra("First_Person_Data");
instantiateUi();
changedName.setText(incomingObject.getPersonName());
changedAge.setText(String.valueOf(incomingObject.getPersonAge()));
changedHeight.setText(String.valueOf(incomingObject.getPersonHeight()));
changedWeight.setText(String.valueOf(incomingObject.getPersonWeight()));
MainActivity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent EditActivity = new Intent(EditData.this, MainActivity.class);
EditData.this.startActivity(EditActivity);
}
});
}
private void instantiateUi() {
changedName = (TextView)findViewById(R.id.changed_name);
changedAge = (TextView)findViewById(R.id.changed_age);
changedHeight = (TextView)findViewById(R.id.changed_height);
changedWeight = (TextView)findViewById(R.id.changed_weight);
MainActivity = (Button)findViewById(R.id.main_activity);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.edit_data_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
And my Parcelable class used for transferring data values:
import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable{
String personName;
int personAge, personHeight, personWeight;
public Person(){
personName = "No Name!";
personAge = 0;
personHeight = 0;
personWeight = 0;
}
public Person(String pName, int pAge, int pHeight, int pWeight) {
personName = pName;
personAge = pAge;
personHeight = pHeight;
personWeight = pWeight;
}
public Person(Parcel in) {
personName = in.readString();
personAge = in.readInt();
personHeight = in.readInt();
personWeight = in.readInt();
}
public String getPersonName() {
return personName;
}
public void setPersonName(String personName) {
this.personName = personName;
}
public int getPersonAge() {
return personAge;
}
public void setPersonAge(int personAge) {
this.personAge = personAge;
}
public int getPersonHeight() {
return personHeight;
}
public void setPersonHeight(int personHeight) {
this.personHeight = personHeight;
}
public int getPersonWeight() {
return personWeight;
}
public void setPersonWeight(int personWeight) {
this.personWeight = personWeight;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(personName);
dest.writeInt(personAge);
dest.writeInt(personHeight);
dest.writeInt(personWeight);
}
public static final Parcelable.Creator<Person> CREATOR =
new Parcelable.Creator<Person>() {
#Override
public Person createFromParcel(Parcel in) {
return new Person(in);
}
#Override
public Person[] newArray(int size) {
return new Person[size];
}
};
}
Sorry if there are problems, this is my first question and I would very much appreciate what help you can give to a noob C0D3R :P
You shouldn't start variable names with capital letters. Your button MainActivity is very confusing. Better name it something like btMainActivity or something like that.
It think your problem is, that you forget to put an extra to your MainActivity, like you did when starting EditData:
editActivity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
firstPerson.setPersonName(editName.getText().toString());
firstPerson.setPersonAge(Integer.parseInt(editAge.getText().toString()));
firstPerson.setPersonHeight(Integer.parseInt(editHeight.getText().toString()));
firstPerson.setPersonWeight(Integer.parseInt(editWeight.getText().toString()));
Intent editIntent = new Intent(MainActivity.this, EditData.class);
editIntent.putExtra("First_Person_Data", firstPerson);
MainActivity.this.startActivity(editIntent);
}
});
MainActivity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent EditActivity = new Intent(EditData.this, MainActivity.class);
// put your extra here
EditData.this.startActivity(EditActivity);
}
});
For what you want, you could also use startActivityForResult. Take a look at it! You should also check out AndroidAnnotations. It can safe you a lot of code and time. I can't imagine making an Android app without it anymore.

My LogCat is displaying idsactly what I described. Would really appreciate a fix guys!
I've seen this for a number of months on my S3 and it's never appeared to cause any problems. The answer here sounds probable to me.
