出现以上现象是：打开相机，拍摄视频后无法预览查看保存的视频；然后提示：
相机无法到连接，请确保已关闭会使用相机或闪光灯的应用程序。
出现以上提示的原因，因为客制化需求导致多修改了该相册其他的类，比如 PhotoPage.java类不用修改！还原修改即可
此需求是屏蔽相册里面的camera按钮，中间一个，右上角一个，当设置禁用相机，隐藏相机图标；当设置相机可用启用，恢复显示可使用。短信附件修改也是如此。
1.相册只需要修改此类：AlbumSetPage.java
/vendor/mediatek/proprietary/packages/apps/Gallery2/src/com/android/gallery3d/app/AlbumSetPage.java
private void showCameraButton() {
if (mCameraButton == null && !setupCameraButton()) return;
//*/ add set invisibility
int camValue = Settings.System.getInt(mActivity.getAndroidContext().getContentResolver(),"tyd_disable_camera", 0);
mCameraButton.setVisibility(camValue == 0 ? View.VISIBLE : View.GONE);
/*/
mCameraButton.setVisibility(View.VISIBLE);
//*/
}
@Override
protected boolean onCreateActionBar(Menu menu) {MenuItem cameraItem = menu.findItem(R.id.action_camera);
//*/add set invisibility
int camValue = Settings.System.getInt(mActivity.getAndroidContext().getContentResolver(),"tyd_disable_camera", 0);
cameraItem.setVisible(camValue != 1);
/*/
cameraItem.setVisible(GalleryUtils.isCameraAvailable(activity));
//*/FilterUtils.setupMenuItems(mActionBar, mMediaSet.getPath(), false);
2./vendor/mediatek/proprietary/packages/apps/Gallery2/src/com/android/gallery3d/app/AlbumPage.java
@Override
protected boolean onCreateActionBar(Menu menu) {//*/add setVisible
int camValue = Settings.System.getInt(mActivity.getAndroidContext().getContentResolver(),"tyd_disable_camera", 0);
menu.findItem(R.id.action_camera).setVisible(camValue != 1);
/*/
menu.findItem(R.id.action_camera).setVisible(
MediaSetUtils.isCameraSource(mMediaSetPath)
&& GalleryUtils.isCameraAvailable(mActivity));
//*/
3.短信只需要修改此类： AttachmentTypeSelectorAdapter.java
根据存值条件判断是否显示还是隐藏
/vendor/mediatek/proprietary/packages/apps/Mms/src/com/android/mms/ui/AttachmentTypeSelectorAdapter.java
protected static List<IconListItem> getData(int mode, Context context) {
List<IconListItem> data = new ArrayList<IconListItem>(8);
addItem(data, context.getString(R.string.attach_image),
R.drawable.ic_attach_picture_holo_light, ADD_IMAGE);
/*/add set camera invisible
addItem(data, context.getString(R.string.attach_take_photo),
R.drawable.ic_attach_capture_picture_holo_light, TAKE_PICTURE);
/*/
int camValue = android.provider.Settings.System.getInt(context.getContentResolver(),"tyd_disable_camera", 0);
if(camValue == 1){//隐藏不添加
}else {//显示添加
addItem(data, context.getString(R.string.attach_take_photo),
R.drawable.ic_attach_capture_picture_holo_light, TAKE_PICTURE);
}
//*/
addItem(data, context.getString(R.string.attach_video),
R.drawable.ic_attach_video_holo_light, ADD_VIDEO);
/*/add,set camera invisible
addItem(data, context.getString(R.string.attach_record_video),
R.drawable.ic_attach_capture_video_holo_light, RECORD_VIDEO);
/*/
int camValue2 = android.provider.Settings.System.getInt(context.getContentResolver(),"tyd_disable_camera", 0);
if(camValue2 == 1){ //隐藏不添加
} else { //显示添加
addItem(data, context.getString(R.string.attach_record_video),
R.drawable.ic_attach_capture_video_holo_light, RECORD_VIDEO);
}
//*/if (MmsConfig.getAllowAttachAudio()) {
addItem(data, context.getString(R.string.attach_sound),
R.drawable.ic_attach_audio_holo_light, ADD_SOUND);
}
差点点吓到我了，还以为真是有什么其他服务模块占用了相机，那就难以排查了，好在做了多方面的验证和测试，最终发现是之前需求修改导致的！
最后，如果log中发现“Fail to connect to camera service”
才表示相机的服务是被其他模块占用了，所以，应该在打开相机之前关闭掉其他服务，hhh, but i dont know how to close others service ！if you know,plaese tell me for studying relatively。
