I have been trying to figure this out all day, as I would like to add an image depending on the outcome of the emotion may detect. Just wanted to add some some images but I'm still new to this. Can anyone help me with this one to.
btw here's my code:

FaceServiceClient faceServiceClient = SampleApp.getFaceServiceClient();
try {
publishProgress("Detecting...");
// Start detection.
return faceServiceClient.detect(
params[0], /* Input stream of image to detect */
true, /* Whether to return face ID */
true, /* Whether to return face landmarks */
new FaceServiceClient.FaceAttributeType[]{
FaceServiceClient.FaceAttributeType.Emotion,
});
} catch (Exception e) {
mSucceed = false;
publishProgress(e.getMessage());
addLog(e.getMessage());

Just would like to add some images like happy if that is the detected emotion. Please do help me. Any help is highly appreciated. Thank you :)
I would like to add that after the emotionInfo.
I guess detectWithStream is you want.
Official Doc: Faces.detectWithStream Method
From Java SDK, the List<DetectedFace> object will return if successful.
I am new to Java coding for android. I need to understand why does my code generate 2 threads. The problem that can be created over here is perhaps competition for Camera Resources which results in the camera not being used by the user. Kindly suggest a solution to my problem as well.
I have also attached a picture where there are 2 requests for a new activity. There is also proof by having 2 thread IDs active.
EDIT for clarity:
I want to generate a new thread which solely handles the activity to record the video, no other thread should be doing it. But there are two that are performing their own activity to record video.

Every time you tap on TextView, as you are using onTouchListener, it will be fired twice, once for ACTION_DOWN and ACTION_UP, so check for ACTION_UP as in
finger_on_sensor.setOnTouchListener(new View.OnTouchListener() {

In my project I download all the data of my project from a json.I download title and description as text and also download my icon and the file of games.
I can download them and also save in database and show in listview easily.
My QUESTION is about how to save that my file for game is beinng download or not?
I have two buttons. first is download button when user click it , it starts to download file.when download finish, my download button disappear and my play button appears.
I want to save this, when user for second time run the application,i save for example my second position downloaded before. and I have just my play button.
my database:
public class DatabaseHandler extends SQLiteOpenHelper {
public SQLiteDatabase sqLiteDatabase;
int tedad;
public DatabaseHandler(Context context) {
super(context, "EmployeeDatabase.db", null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
String tableEmp = "create table emp(PersianTitle text,Description text,icon text,downloadlink text,dl integer)";
db.execSQL(tableEmp);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
public void insertData(ArrayList<String> id, ArrayList<String> name, ArrayList<String> salary, ArrayList<String> roms,String
dl) {

try {
for (int i = 0; i < size; i++) {
ContentValues values = new ContentValues();
values.put("PersianTitle", id.get(i));
values.put("Description", name.get(i));
values.put("icon", salary.get(i));
values.put("downloadlink", roms.get(i));
values.put("dl", "0");
sqLiteDatabase.insert("emp", null, values);
}
} catch (Exception e) {

}
}

how to make method in my database to do this?
If I understood you properly, you can add a table, user_games for example with User ID, Game ID and Status, then you can update status whenever an action is completed.
For example Status 1 for downloading, status 2 for Downloaded or Finished and you can even add statuses like download failed, to add a re-download button...
you can do something like
public void update_status(UserID,GameID) {
String update = "UPDATE games set status = 1 where id="+Game_ID+" and UserID = " + UserID);
db.rawQuery(update, null);
}
So I am doing a Create Your Own Adventure game/book in for an Android class for a final project. The way I have it set up is with two activities (A menu and a page layout). I have a "Master File" text file that has the relationships between each page (example below). I also have the "pages" setup in text files that need to be retrieved and then set to the TextView and the 3 buttons. (example below of how they are setup.
My question is how am I supposed to retrieve that information correctly.
I want to have it setup that when the Page class does an OnCreate it fills in the textview and the 3 buttons from the correct Page.txt file.
This is my page.class the code for the pages.
public class pages extends AppCompatActivity {
ArrayList<FileRelationship> fileRelationships;
FileRelationship selectedRelationship;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.page);
fileRelationships = new ArrayList<FileRelationship>();
String MasterLine;
InputStream inputStream = this.getResources().openRawResource(R.raw.MasterFile);
InputStreamReader inputreader = new InputStreamReader(inputStream);
BufferedReader buffreader = new BufferedReader(inputreader);
// Creates the arrayList of all the relationships for later use of retreival.
try {
while (( MasterLine = buffreader.readLine()) != null) {
String[] MasterLineArray = MasterLine.split(",");
String filename = MasterLineArray[0];
String choice1 = MasterLineArray[1];
String choice2 = MasterLineArray[2];
String choice3 = MasterLineArray[3];
FileRelationship fr = new FileRelationship(filename, choice1, choice2, choice3);
fileRelationships.add(fr);
}
} catch (IOException e) {
}
TextView storyText = (TextView) findViewById(R.id.storyText);
Button choice1 = (Button) findViewById(R.id.firstchoice);
choice1.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
findRelationship(selectedRelationship.firstLink);
finish();
startActivity(getIntent());
}
});
Button choice2 = (Button) findViewById(R.id.secondchoice);
choice2.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
findRelationship(selectedRelationship.secondLink);
finish();
startActivity(getIntent());
}
});
Button choice3 = (Button) findViewById(R.id.thirdchoice);
choice3.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
findRelationship(selectedRelationship.thirdLink);
finish();
startActivity(getIntent());
}
});
// **THIS IS THAT PART I NEED HELP WITH THE MOST** I dont know what
// to put in the setText part to have it retrieve the correct information.
storyText.setText();
choice1.setText();
choice2.setText();
choice3.setText();
}
public void findRelationship(String nextFileName) {
int pageIndex = fileRelationships.indexOf((new FileRelationship(nextFileName)));
selectedRelationship = fileRelationships.get(pageIndex);
}
}
This is my FileRelationship class, that I use to create the array in my page class.
public class FileRelationship {
String fileName;
String firstLink;
String secondLink;
String thirdLink;
public FileRelationship(String fileName) {
this.fileName = fileName;
}
public FileRelationship(String fileName, String firstLink, String secondLink, String thirdLink) {
this.fileName = fileName;
this.firstLink = firstLink;
this.secondLink = secondLink;
this.thirdLink = thirdLink;
}
public boolean equals(Object o) {
if(o == null) {
return false;
}
if(this == o) {
return true;
}
if(o instanceof FileRelationship) {
return this.fileName.equals(((FileRelationship)o).fileName);
}
return false;
}
}
This is how my MasterFile.txt is setup to define the relationships (Just an example)
Page1,Page2,Page3,Page4
Page2,Page5,Page6,Page7
Page3,Page8,Page9,Page10
And finally this is how my Page1,Page2,Page3 etc. will be setup (Again just an example)
This is a practice story line, my pages text will go into here and create the story in this way.
Choice 1
Choice 2
Choice 3
Is the best way to create a method that retrieves the information from the selectedRelationship and then puts all 4 of them into strings? If so how can this be done. I also am not sure if my FindRelationship method is correct either.
Any help would be appreciated. I feel like I have everything else correct, but I wasn't also sure if I am retrieving the MasterFile parts correctly and putting it into the array list correctly either. Any help would be much appreciated. Thanks!
How can I put the result of the QR "SCAN_RESULT" in different activity, this is my problem.
In the splash screen I need to go to the QRScanner (CaptureActivity), and then, to the ActivityQR who will send the info. to the SQLite.
The problem is: When I get de QRCode in string ("SCAN_RESULT") on "CaptureActivity.java", the app close because the app need "back" to the previous activity with this:
getIntent();
I try to modify this codeline, but this not solve my problem.
How can I put the "SCAN_RESULT" in the ActivityQR? I don't know how open other activity (this case ActivityQR) when the code had gottenm and put this String value on the ActivityQR
I Use "CaptureActivity" of ZXing (ZebraCrossing)
Thanks in advance.

your SplashScreen Java should look like this:
{
Intent mainIntent = new Intent().setClass(SplashScreenActivity.this, com.google.zxing.client.android.CaptureActivity.class);
// use startActivityForResult instead of startActivity
startActivityForResult(mainIntent)
}
but I guess you already solved you problem!
