camera2 を textureView と統合しました。すべてのデバイスで動作しますが、タブレットでは初めて画像をキャプチャするときにクラッシュし、次のログが表示されます。
Fatal Exception: java.lang.IllegalArgumentException: Surface had no valid native Surface.

次のコードは、画像をキャプチャするために使用されます。
protected void takePicture() {
if (getContext() == null || cameraDevice == null) return;
lockFocus();
CameraManager manager = (CameraManager) getContext().getSystemService(Context.CAMERA_SERVICE);
try {
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraDevice.getId());
if (characteristics != null) {
sizes = characteristics.get(CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP).getOutputSizes(ImageFormat.JPEG);
}
ImageReader reader = getImageReader();
if (reader == null) return;
List<Surface> outputSurfaces = getSurfaces(reader);
final CaptureRequest.Builder captureBuilder = getCaptureBuilder(reader);
final CameraCaptureSession.CaptureCallback captureListener = new CameraCaptureSession.CaptureCallback() {
@Override
public void onCaptureCompleted(CameraCaptureSession session, CaptureRequest request, TotalCaptureResult result) {
super.onCaptureCompleted(session, request, result);
}
};
cameraDevice.createCaptureSession(outputSurfaces, new CameraCaptureSession.StateCallback() {
@Override
public void onConfigured(CameraCaptureSession session) {
try {
session.capture(captureBuilder.build(), captureListener, null);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onConfigureFailed(CameraCaptureSession session) {
}
}, null);
} catch (Exception e) {
e.printStackTrace();
}
}
どんな助けでも大歓迎です。
