[英]Error E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException:: open failed: ENOENT (No such file or directory)
[英]BitmapFactory open failed: ENOENT (No such file or directory)
我正在嘗試使用 Android 相機意圖拍照,如本教程所示: http : //developer.android.com/training/camera/photobasics.html#TaskScalePhoto
照片是完美拍攝的,並且在給定的路徑上也是安全的。 但無論如何我收到以下錯誤:
06-25 14:46:02.228 9070-9070/de.ema.flo.grapp E/BitmapFactory:無法解碼流:java.io.FileNotFoundException:文件:/storage/emulated/0/Android/data/de.ema .flo.grapp/files/Pictures/IMG_20150625_144559002.JPG:打開失敗:ENOENT(沒有那個文件或目錄)
創建圖像:
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmssSSS").format(new Date());
File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = new File(storageDir, "IMG_" + timeStamp + ".JPG");
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
在 Intent 中拍攝照片后調用以下代碼
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == ACTION_TAKE_PHOTO_B && resultCode == Activity.RESULT_OK) {
if (mCurrentPhotoPath != null) {
ImageView mImageView = (ImageView) getActivity().findViewById(R.id.grillplatz_erstellen_image);
Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath);
// Associate the Bitmap to the ImageView
mImageView.setImageBitmap(bitmap);
mCurrentPhotoPath = null;
}
}
}
我也用這個嘗試過。 但結果是一樣的:FileNotFoundException...
try {
InputStream is = new FileInputStream(file);
Bitmap bitmap = BitmapFactory.decodeStream(is);
} catch (FileNotFoundException e) {
e.printStacktrace();
}
這段代碼有問題嗎? 我可以嘗試改變什么?
請檢查更新的代碼。
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmssSSS").format(new Date());
File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
if(!storageDir.isexist)
storageDir.mkdirs();
File image = new File(storageDir, "IMG_" + timeStamp + ".JPG");
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
讓我知道它是否對你有幫助。
