[Q] My bluetooth music a2dp doesn't work and i don't know why

Basically, I'd just managed to get this tablet to pick up my dmzmusic a2dp adapter, then I went to sleep and turned off Bluetooth.
I rebooted it in the morning because,hey, why not.
I open up quick settings and toggle Bluetooth on.. and it doesn't turn on. It doesn't even search for devices, nothing's connected to it as Bluetooth doesn't turn on.
I leaves it for a while and get the same result..
Then I take a logcat using play store app catlog and come crying for help like a baby. Is there anyone who can help me?

Camera Preview

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.

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.

Using setPixels makes the app crash

Hi everybody,
I'm new to android coding, so I'm just making same small tests with the API.
Right now I have a problem using setPixels, it makes my app crash when I use it.
Here is the beginning of the onCreate :
Code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
ImageView image = (ImageView) findViewById(R.id.sly);
Bitmap bMap = BitmapFactory.decodeResource(getResources(), R.drawable.pic793849);
final int bMapWidth = bMap.getWidth();
final int bMapHeight = bMap.getHeight();
int[] pixels = new int[bMapHeight*bMapWidth];
bMap.getPixels(pixels, 0, bMapWidth, 0, 0, bMapWidth, bMapHeight);
for(int i=0 ; i<bMapHeight; i++)
{
for(int j=0 ; j<bMapWidth; j++)
{
//pixels[ i + (j*bMapHeight)] ^= 77;
}
}
bMap.setPixels(pixels, 0, bMapWidth, 0, 0, bMapWidth, bMapHeight);
// image.setImageBitmap(bMap);
final View controlsView = findViewById(R.id.fullscreen_content_controls);
final View contentView = findViewById(R.id.fullscreen_content);
If I comment the setPixels line, the app runs fine, if I uncomment it, it crashed right away.
I don't get what I'm doing wrong, the bMap is allocated, the pixels too, I'm not out of bounds... any help would be appreciated !

Thanks in avance...

Caused by: IllegalStateException. http://developer.android.com/reference/android/graphics/Bitmap.html#setPixel(int, int, int) says: setPixel throws ISE
if the bitmap is not mutable. Conclusion: you need to make the bitmap mutable

Thank you very much, it works.
I added those lines :
Code:
BitmapFactory.Options options = new BitmapFactory.Options();
options.inMutable = true;
Bitmap bMap = BitmapFactory.decodeResource(getResources(), R.drawable.pic793849, options);

Random Media Pauses

I have a strange problem that started recently where media I'm listening to/watching will randomly pause. It happens both when playing on my phone and when playing over bluetooth to my car or headphones. Sometimes it happens when my phone is sitting on the counter and I'm not touching it. I've had it happen in both Pocket Casts and Youtube Vanced, but those are the only two media apps I use regularly.
I was able to grab a logcat where I started a podcast and then it paused a second or two after it started. I've tried to read through it but I can't really make sense of it. Here are two sections I think might be relevant, but I'm not really sure what it means:
Code:

I can't post a link to the full logcat because I'm a new user, but if anyone wants to look at it let me know.
If anyone has any ideas as to what would be causing this I'd love to hear!
Thanks!
