Android保存Bitmap图片到指定文件夹_android 将bitmap保存到根目录

        在内存中先读取到一张图片，格式为Bitmap，之后要将其保存到自己游戏安装目录下的某一文件夹中，代码如下（函数的参数为

一Bitmap的数据）：

public void save(Bitmap bitmap) {
		try {
			File file = new File(Environment.getExternalStorageDirectory()
					+ "/Android/data/com.XXX.XXX/files");
			if (!file.exists()) {
				file.mkdirs();
			}
			File myFaceFile = new File(
					Environment.getExternalStorageDirectory()
							+ "/Android/data/com.XXX.XXX/files/Name.png");
 
			if (myFaceFile.exists()) {
				return;
			}
			OutputStream stream = new FileOutputStream(myFaceFile);
			bitmap.compress(CompressFormat.PNG, 100, stream);
			stream.close();
			Intent intent = new Intent();
			intent.setAction(Intent.ACTION_MEDIA_MOUNTED);
			intent.setData(Uri.fromFile(Environment
					.getExternalStorageDirectory()));
			sendBroadcast(intent);
			this.runOnUiThread(new Runnable() {
				public void run() {
					Toast.makeText(ThisContext, "保存图片成功", Toast.LENGTH_SHORT)
							.show();
				}
			});
			UnityPlayer.UnitySendMessage("1PanelOfUserAccount", "ChangeFace",
					"Name.png");
		                } catch (Exception e) {
 
			this.runOnUiThread(new Runnable() {
				public void run() {
					Toast.makeText(ThisContext, "保存图片失败", Toast.LENGTH_SHORT)
							.show();
				}
			});
			e.printStackTrace();
		}
		try {
			File tempFile = null;
			tempFile.delete();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
