Im trying to start a simple app and i need to display on a SurfaceView the preview of the cam as soon as the App start.
i added the permission to the manifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
and my code:
Code:
import android.content.Context;
import android.hardware.Camera;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class MainActivity extends SurfaceView implements SurfaceHolder.Callback{
SurfaceView mSurfaceView;
private SurfaceHolder mHolder;
public Camera camera = null;
public MainActivity(Context context) {
super(context);
mSurfaceView = (SurfaceView) findViewById(R.id.surfaceView);
mHolder = mSurfaceView.getHolder();
mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
[user=439709]@override[/user]
public void surfaceCreated(SurfaceHolder holder) {
camera = Camera.open();
try{
camera.setPreviewDisplay(mHolder);
} catch(Exception e){
}
}
[user=439709]@override[/user]
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
Camera.Parameters params = camera.getParameters();
params.setPreviewSize(width,height);
camera.setParameters(params);
camera.startPreview();
}
[user=439709]@override[/user]
public void surfaceDestroyed(SurfaceHolder holder) {
camera.stopPreview();
camera = null;
}
}
Ive looked for many tutorial and all technically do the same or smiliart stuff. But the app crashes. I cant find a solution

On Eclipse i know how to show the windows of the LogCat, but cant really find it here on Android Studio.
Im a bit newby about this sorry, coming from PHP using just Notepad.
Guess i found it, added log cat
I saw some tutorial like this, im not sure why it doesnt start.
Is it for te onCreate method missing? but i saw that for other works anyway like this
Btw i've also triyed an other way, but stills give me errors. i could upload that one too, different logcat.
Hope one of the two could be solved

In Android you normally do not use the constructor of an Activity for anything.
Use the onCreate method instead.
EDIT: The log says that the constructor must be empty.

I thought about that (even if i saw video tutorial doing it) so i tried wht onCreate method and now it seams to give problem with the setParameters?
Ive uploaded the new code and logcats before
Ah. Check this: http://stackoverflow.com/questions/3890381/camera-setparameters-failed-in-android

i tryed that at th beggin, and didnt work, in fact i tried it again and still give me the same error apparently
While I'm still learning myself, it looks like you are getting a failed camera permission. And then it tries to pass in an invalid parameter to the camera.

But cant understand which one and how should i do. it ryed the 2 ways everybody does
What phone are you trying this on? Have you tried it in an emulator?
After getting home and I was able to try your second piece of code. It looks like it is a problem with <CODE>params.setPreviewSize(arg2, arg3);</CODE>, it doesn't like the width and height arguments. I found THIS(second answer). and after plugging it into your code it was working for me. If you like I can show you the modified code, altho its real easy to plug in.

i tryed his first example and finally i get his "distoted" image. When i'll have time ill try the rets thnk u very much
ill try this:
Code:
Camera.Size getBestPreviewSize(int width, int height, Camera.Parameters parameters) {
Camera.Size result=null;
float dr = Float.MAX_VALUE;
float ratio = (float)width/(float)height;
for (Camera.Size size : parameters.getSupportedPreviewSizes()) {
float r = (float)size.width/(float)size.height;
if( Math.abs(r - ratio) < dr && size.width <= width && size.height <= height ) {
dr = Math.abs(r - ratio);
result = size;
}
}
return result;
}
Code:
ublic void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
// Now that the size is known, set up the camera parameters and begin
// the preview.
if (isPreviewRunning) {
mCamera.stopPreview();
}
Camera.Parameters parameters = mCamera.getParameters();
List<Size> sizes = parameters.getSupportedPreviewSizes();
Size optimalSize = getBestPreviewSize( w, h, parameters);
parameters.setPreviewSize(optimalSize.width, optimalSize.height);
mCamera.setParameters(parameters);
mCamera.startPreview();
isPreviewRunning =true;
}
im not sure abot the 3rd parameter of the getBestPreviewSize method which one is it. Like this is still distorted
Yeah, I could never fix the distortion back when I was trying my camera app. But I think I will tinker with it again. Keep this updated if you find anything, I will also.

Hey guys!
I know most of you have never heard of this, but there's a organisation that provides many useful things to use in your app!
It's called "Parse"
Now, I will guide you trough the use of Parse, beginning with Parse Push. Let's get started, shall we?
Section 1:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Okay, so Parse Push is a "library" or service that makes it A LOT easier to send push notifications to the users of your app. I had searched for months on how to send push notifications, but I just never succeeded (And I can't afford a proper server ). But that's where Parse Push comes in!
The first thing you'll have to do to setup Parse Push is download and install the Parse SDK. This is how:
Step 1: Make an account at Parse.com and setup the app you want to include Parse in.
Step 2: Download the SDK: https://parse.com/downloads/android/Parse/latest
Step 3: Unzip it into a random folder
Step 4: Copy all the files in your projects "lib" folder. If your project doesn't have one, simply make one in the root of your directory (e.g /MyApp/lib/)
Step 5: Call the "initialize" method in your onCreate method, like this:
Code:
Parse.initialize(this, "Your application ID", "Your client key");
NOTE: You can find you application ID and client key here: https://parse.com/apps/YOUR-APP'S-NAME/edit#app_keys
NOTE: Be sure you also imported these calls:
Code:
import com.parse.Parse;
import com.parse.ParseAnalytics;
Step 6: Your app needs the android.permission.INTERNET and android.permission.ACCESS_NETWORK_STATE permission to work with Parse, so add these lines in your AndroidManifest.xml file, right before the <application> tag:
Code:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Also, add this between the <application> and </application> tag:
Code:
<service android:name="com.parse.PushService" />
<receiver android:name="com.parse.ParseBroadcastReceiver">
Step 7: Place this code in your onCreate method to track how many times your app has been opened:
Code:
ParseAnalytics.trackAppOpened(getIntent());
Step 8: It's testing time!
To test if your app has been setup the right way, add this code to your onCreate method:
Code:
ParseObject object = new ParseObject("TestObject");
object.put("name", "testname");
object.saveInBackground();
And run your app!
Step 9: Get your data trough a web browser! Go to this site: https://parse.com/apps/YOUR-APP'S-NAME/collections
Then it should say something like: TestObject (1), with the name testname
Step 10: Send a push notification: Goto https://parse.com/apps/YOUR-APP'S-NAME/push_notifications and click on + Send a push
Type in your message, hit Send notification at the bottom and your app will get a push notification!
That's it! You have now setup your app to receive push notifications
Okay, here we go, the next section
Section 2: Parse Users
So, the ParseUser class is a really useful thingy for people who want to have some more control over the people who use their apps.
You can (for example) set a username, and then when the user wants to post something in the app, instead of him having to type his name all over again, the app can just use the ParseUser.getCurrentUser().getUsername() method, and it will automatigally get the user's name for him!
Now I'll show you how to setup a ParseUser:
Step 1: Setup everything in the same way as you did in Section 1
Step 2: First we'll have to make a ParseUser, by signing up. Here's a quick signing up code snippet:
Code:
ParseUser signup = new ParseUser();
signup.setUsername("testuser");
signup.setPassword("testpassword");
signup.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Hooray! Let them use the app now.
// The user also is logged in now :)
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
// Mostly the problem is that the username is already taken
}
But, ofcourse the user wants to choose his own username and password. For that you can use an EditText:
Code:
EditText username = (EditText) findViewById(R.id.USERNAMEEDITTEXTiD);
EditText password = (EditText) findViewById(R.id.PASSWORDEDITTEXTiD);
ParseUser signup = new ParseUser();
signup.setUsername(username.getText().toString());
signup.setPassword(password.getText().toString());
signup.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Hooray! Let them use the app now.
// The user also is logged in now :)
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
// Mostly the problem is that the username is already taken
}
But, if the user didn't type in anything, signin up throws a IllegalArgumentException. You can avoid that by using try and catch claws, like in this example:
Code:
EditText username = (EditText) findViewById(R.id.USERNAMEEDITTEXTiD);
EditText password = (EditText) findViewById(R.id.PASSWORDEDITTEXTiD);
try {
ParseUser signup = new ParseUser();
signup.setUsername(username.getText().toString());
signup.setPassword(password.getText().toString());
signup.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Hooray! Let them use the app now.
// The user also is logged in now :)
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
// Mostly the problem is that the username is already taken
}
} catch (IllegalArgumentException IO {
// The user didn't type in anything, I suggest using a Toast to notify him
}
Now, if a user wants to post something using his account name, you can get his username using this:
Code:
ParseUser currentUser = ParseUser.getCurrentUser();
currentUser.getUsername();
If your user wants to login, you can use this:
Code:
EditText username = (EditText) findViewById(R.id.USERNAMEEDITTEXT);
EditText password = (EditText) findViewById(R.id.PASSWORDEDITTEXT);
ParseUser.logInInBackground(username.getText().toString(), password .getText().toString(), new LogInCallback() {
public void done(ParseUser user, ParseException e) {
if (user != null) {
// Hooray! The user is logged in.
} else {
// Signup failed. Look at the ParseException to see what happened.
// The main cause is that the user didn't type in a correct username or password
}
}
});
And if you want to log the user out, you can do it very simply by calling:
Code:
ParseUser.logOut();
And that's it! You just learned how to signup a user, log him in, get his username and log him out!
Now it's time for the next section!
Time for section 3!
Section 3: Parse Data
Huh, what is Parse Data? Well, that's a good question sir! P) Parse Data will let you save ParseObjects into the Parse Cloud. That will allow you to store all of your data, and if you want you can read it back too! This could be useful for games with highscores, forum apps and more! Another great part of Parse!
Let's start with saving a ParseObject to the cloud, shall we?
Step 1: Setup your app the same way you did in Section 1
Step 2: We'll start with a really simple ParseObject, for now it's going to be called "testObject"
Here's a quick example for a ParseObject that will save to the cloud:
Code:
ParseObject testObject= new ParseObject("testObject");
testObject.put("name", "TestObject's name");
testObject.put("random",true);
testObject.put("someint", 1337);
testObject.saveInBackground();
As you can see, we can put everything we want in it (e.g. testObject.put("ASDASDASDA", "ASDASDASD")
They don't always have to be strings, they can be booleans, ints, strings, JSON objects, java.util.Date, byte[] or ParseObjects(That's right, you can save a ParseObject inside a ParseObject )
You can also wait for the user untill he has an internet connection, and when he finally has, save the object:
Code:
ParseObject testObject= new ParseObject("testObject");
testObject.put("name", "TestObject's name");
testObject.put("random",true);
testObject.put("someint", 1337);
testObject.saveEventually();
For retreiving the object, you can do something like this:
Code:
ParseQuery<ParseObject> query = ParseQuery.getQuery("testObject");
query.getInBackground("YOUROBJECTID", new GetCallback<ParseObject>() {
public void done(ParseObject object, ParseException e) {
if (e == null) {
// everything went okay :D
} else {
// something went wrong D:
}
}
})
Updating a ParseObject is really simple, just use the same as you did before, but with new data in the testObject.put("somedata", "the data"); section
Deleting it is farely simple as well, just use this:
Code:
testObject.deleteInBackground();
You can also delete just one field:
Code:
testObject.remove("name");
testObject.saveInBackground();
And that's it for now!
And again, mine
Last one
This really is the last one!
Wow! Great. :good:
Thanks.
How much is the 1 GB per month which you get for free?
EDIT: Saw that this is the storage. You get 1,000,000 notifications for free.

Well it's really good, as 100 push notifications is just 0.1 % of the whole 1 GB
So, it's enough for me

10 kB per message? Sounds good. Thanks.
ParseUsers section updated!
Ok. Just saw that you get 1,000,000 messages for free.
That is great for small apps but if you go beyond that, it will be very expensive. However, I cannot compare it to the price of a server.
Any experiences?

Yeah, well, the internet keeps getting more and more expensive. I don't like it either, but my app isn't that big so I can live with it
ParseData section updated!
Good job Maarten! So this is your method..! xD
Keep it up!

android:layout_height="match_parent"
android:id="@+id/mapFragment"
class="com.google.android.gms.maps.MapFragment"/>
My wear main activity implements OnMapReadyCallback :
Code:
@Override
public void onMapReady(GoogleMap map) {
SupportMapFragment fragment = ( SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment);
// Getting Google Map
GoogleMap googleMap = fragment.getMap();
Finally, i've got this error :

Is it really possible to display a map on a watch ? If yes, can you tell me how ?
Thanks in advance
I think that the Google Play Services on Android Wear doesn't have the Map API so java.lang.IllegalStateException was thrown. So no, you can't use the Map API directly on Wear devices
Thanks for your answer

Thanks for your answer. This application uses Google Maps Static API and apparently, the number of recovered images is limited :/
Can't you make an handled app that uses google map, with wear app synchronizing the displayed picture?
