Android -- Camera源碼簡析，啟動流程

boolean recordLocation = RecordLocationPreference.get(

mPreferences, getContentResolver());

mLocationManager.recordLocation(recordLocation);

//設(shè)置SD卡廣播

installIntentFilter();

mImageSaver = new ImageSaver();

//初始化Zoom

initializeZoom();

//mMediaProviderClient=媒體Provider對象

keepMediaProviderInstance();

//檢查硬盤

checkStorage();

//淡出retake和done的Button

hidePostCaptureAlert();

if (!mIsImageCaptureIntent) {

//如果不是第三方開啟，則更新縮略圖

updateThumbnailButton();

mModePicker.setCurrentMode(ModePicker.MODE_CAMERA);

}

}

復(fù)制代碼

4、surfaceDestroyed

stopPreview();

mSurfaceHolder = null;
