为什么Unity3D Application.CaptureScreenshot for Android不能工作？
为什么Unity3D Application.CaptureScreenshot for Android不能工作？
提问于 2015-02-24 01:08:40
我试过以下所有这些链接：
Not getting image from Persistant path in Android using unity3d
http://answers.unity3d.com/questions/731509/applicationcapturescreenshot-doesnt-save-anything.html
I need to set the path for saving the pictures with an application for Android and IOS with UNITY
http://answers.unity3d.com/questions/200173/android-how-to-refresh-the-gallery-.html#answer-893069
每次我构建一个apk，安装在Android设备上，什么都不会发生。日志不存在，所以我尝试了所有这些链接，然后转到/DCIM/Camera/查看它是否被保存，不，没有.
在iOS上，我做到了这一点，而且工作得很完美。
这是我卡住的代码..。否则Android上的东西就不能用了..。我不知道为什么文件夹中没有出现错误或者文件奇怪
void saveImage()
{
#if UNITY_ANDROID
string theFileName = "Screenshot_" + System.DateTime.Now.ToString("MM_dd_yyyy") +"_"+ System.DateTime.Now.ToString("hh_mm_ss") +".png";
// Many different test, trying to discovery witch will work...
Application.CaptureScreenshot( Application.dataPath + "_" + theFileName );
Application.CaptureScreenshot( "../../../../DCIM/Camera/pathroot_" + theFileName );
Application.CaptureScreenshot( "/storage/emulated/0/DCIM/Camera/" + theFileName );
Application.CaptureScreenshot( "file:///storage/emulated/0/DCIM/Camera/" + theFileName );
StartCoroutine(TakeScreenshot()); // Different test
#endif
#if UNITY_IPHONE
// This work... so, does not need to be here...
#endif
}这是"Coroutine“调用的方法(从上面的一个链接复制)：
private IEnumerator TakeScreenshot()
{
yield return new WaitForEndOfFrame();
//INITIAL SETUP
string myFilename = "Screenshot_" + System.DateTime.Now.ToString("MM_dd_yyyy") +"_"+ System.DateTime.Now.ToString("hh_mm_ss") +".png";
string myDefaultLocation = Application.dataPath + "/" + myFilename;
//EXAMPLE OF DIRECTLY ACCESSING THE Camera FOLDER OF THE GALLERY
//string myFolderLocation = "/storage/emulated/0/DCIM/Camera/";
//EXAMPLE OF BACKING INTO THE Camera FOLDER OF THE GALLERY
//string myFolderLocation = Application.persistentDataPath + "/../../../../DCIM/Camera/";
//EXAMPLE OF DIRECTLY ACCESSING A CUSTOM FOLDER OF THE GALLERY
string myFolderLocation = "/storage/emulated/0/DCIM/Camera/";
string myScreenshotLocation = myFolderLocation + myFilename;
//ENSURE THAT FOLDER LOCATION EXISTS
if(!System.IO.Directory.Exists(myFolderLocation)){
System.IO.Directory.CreateDirectory(myFolderLocation);
}
//TAKE THE SCREENSHOT AND AUTOMATICALLY SAVE IT TO THE DEFAULT LOCATION.
Application.CaptureScreenshot(myFilename);
//MOVE THE SCREENSHOT WHERE WE WANT IT TO BE STORED
System.IO.File.Move(myDefaultLocation, myScreenshotLocation);
//REFRESHING THE ANDROID PHONE PHOTO GALLERY IS BEGUN
AndroidJavaClass classPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject objActivity = classPlayer.GetStatic<AndroidJavaObject>("currentActivity");
AndroidJavaClass classUri = new AndroidJavaClass("android.net.Uri");
AndroidJavaObject objIntent = new AndroidJavaObject("android.content.Intent", new object[2]{"android.intent.action.MEDIA_MOUNTED", classUri.CallStatic<AndroidJavaObject>("parse", "file://" + myScreenshotLocation)});
objActivity.Call ("sendBroadcast", objIntent);
//REFRESHING THE ANDROID PHONE PHOTO GALLERY IS COMPLETE
//AUTO LAUNCH/VIEW THE SCREENSHOT IN THE PHOTO GALLERY
Application.OpenURL(myScreenshotLocation);
//AFTERWARDS IF YOU MANUALLY GO TO YOUR PHOTO GALLERY,
//YOU WILL SEE THE FOLDER WE CREATED CALLED "myFolder"

试试这个：(测试和工作)：
Application.CaptureScreenshot ("screenshot.png")；
存储屏幕截图: Application.persistentDataPath，"screenshot.png“，即数据/数据/包_name/file
void captureScreenshot(string result){
if (result == "true") {
StartCoroutine(CaptureScreen());
}
}
void OnGUI(){
if (GUI.Button (new Rect (20, 70, 100, 45), "Click"))
captureScreenshot ("true");
}
public IEnumerator CaptureScreen()
{
// Wait for screen rendering to complete
yield return new WaitForEndOfFrame();
Application.CaptureScreenshot ("screenshot.png");
string Origin_Path = System.IO.Path.Combine (Application.persistentDataPath, "screenshot.png");
Debug.Log ("Origin_Path save is " + Origin_Path);
// This is the path of my folder.
string Path = "/mnt/sdcard/" + "screenshot.png";
Debug.Log ("Path save is " + Path);
if (System.IO.File.Exists (Origin_Path)) {
System.IO.File.Move (Origin_Path, Path);
Debug.Log ("Path_move save is " + Path);
}
jo.Call<bool> ("screenshotHandler", "screenshot.png");
}如果您想在图库中存储而不再次移动，则可以使用：
Application.CaptureScreenshot (“././../DCIM/creshot.png”)；
如果错误: System.IO.File.Exists (Origin_Path)
//返回FALSE，即使在Origin_Path中存在文件。
请试试这个：
public IEnumerator CaptureScreen()
{
Application.CaptureScreenshot ("../../../../DCIM/"+fileName);
Debug.Log ("Sanky: Screen Captured");
while (!File.Exists (filePath)) {
Debug.Log ("Sanky: File exist at location"+filePath);
yield return 0;
}
/////// do whatever you want
