I want to use old camera api in android M, but when I run my app I get this null pointer exception:
java.lang.RuntimeException: Unable to resume activity {com.in.ri.instacam/com.in.ri.in.Camera.ActivityCamera}: java.lang.NullPointerException: Attempt to invoke virtual method 'android.hardware.Camera$Parameters android.hardware.Camera.getParameters()' on a null object reference

My code is
private void setUpCamera(final int id) {
mCameraInstance = getCameraInstance(id);
Parameters parameters = mCameraInstance.getParameters();
// TODO adjust by getting supportedPreviewSizes and then choosing
// the best one for screen size (best fill screen)
if (parameters.getSupportedFocusModes().contains(
Parameters.FOCUS_MODE_CONTINUOUS_PICTURE)) {
parameters.setFocusMode(Parameters.FOCUS_MODE_CONTINUOUS_PICTURE);
}
mCameraInstance.setParameters(parameters);
int orientation = mCameraHelper.getCameraDisplayOrientation(
ActivityCamera.this, mCurrentCameraId);
CameraHelper.CameraInfo2 cameraInfo = new CameraHelper.CameraInfo2();
mCameraHelper.getCameraInfo(mCurrentCameraId, cameraInfo);
boolean flipHorizontal = cameraInfo.facing == CameraInfo.CAMERA_FACING_FRONT;
mGPUImage.setUpCamera(mCameraInstance, orientation, flipHorizontal, false);
}
Can I use an older camera api in android M? The same code works fine in below M(API 6) versions of android.
