StartPreview не удалось, но не все устройства ⇐ Android

[Anonymous]

Я получаю ошибку startpreview, но не все устройства.
В Motorola Razr и Samsung Galaxy S3, он работает очень хорошо.
Некоторые люди сказали мне, что у них такая же проблема в других устройствах (Galaxy Sii Lite, Galaxy Ace Duos, Samsung y, и т. Д. Logcat < /p>

Изменить 1 - 06/20/2013 < /h2>

Я немного меняю свой код и теперь работает в моей Galaxy y, но мой Framelayout с камерой не работает. Я получаю черный экран на Framelayout.
Кто -нибудь знает, почему?this.holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
< /code>

Я изменил свой surfacecreated < /code> и surfacechanged < /code> на этот < /p>

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
try {
camera.stopPreview();
parameters = parametrosCamera();
camera.setParameters(parameters);
camera.setDisplayOrientation(90);
camera.setPreviewDisplay(holder);
camera.startPreview();
}
catch (IOException e) {
}
catch (Exception e){
}
}

@SuppressLint("NewApi")
@Override
public void surfaceCreated(SurfaceHolder holder) {
try {
camera = Camera.open(0);
camera.setPreviewDisplay(this.holder);
camera.startPreview();
} catch (IOException ioe) {
} catch (Exception e){
}
}
< /code>

p.s.

Я добавил несколько журналов, чтобы получить размер my setpreviewsize < /code> получается с помощью моего метода < /p>

private Parameters parametersCamera(){
Parameters parameters = camera.getParameters();
List sizes = parameters.getSupportedPreviewSizes();
if (sizes != null){
Size min = sizes.get(0);
for (Size size : sizes){
if (size.width < min.width){
min = size;
}else{
parameters.setPreviewSize(min.width, min.height);
parameters.setPictureSize(min.width, min.height);
Log.i("Ultima Camera Width: " + min.width, "Ultima Camera Height: " + min.height);
}
}
parameters.set("orientation", "portrait");
parameters.setRotation(90);
}
if (parameters.getFlashMode() != null){
parameters.setFlashMode(Parameters.FLASH_MODE_AUTO);
}
return parameters;
}
< /code>

и я добавил журнал в SurfaceChanged < /code>, чтобы получить ширину и высоту (я не использую эту ширину и высоту) и посмотрите, одинаково, и я получаю этот результат < /p>

Motorola razr HD (работает очень 573
method parametrosCamera: 640 x 480

Samsung Galaxy Y (don't show my preview)

surfaceChanged: 240 x 162 (W x H)
method parametrosCamera: 320 x 240

and in my Метод параметровкамеры я использую эти две строки < /p>

parameters.set("orientation", "portrait");
parameters.setRotation(90);
< /code>

Я думаю, что ответ на мой вопрос в этой части моего кода. < /p>
