I am trying following:
- 1) On button Click select image from gallery
- 2) set Selected image to imageview
- 3) save Uri to shared Preference (when activity start i check sharedpreference value for selected image. if exist then set image to imageview)
Code to check path is already store in sharedpreference or not, if yes then set image to imageview:
sharedpreferences = getSharedPreferences(MyPREFERENCES,
Context.MODE_APPEND);
String uriImage = sharedpreferences.getString("imageUri", "");
if (!uriImage.equals(""))
{
if (Build.VERSION.SDK_INT < 19) {
//No Problem Here
}
else
{
try
{
//error occur here
parcelFileDescriptor = getContentResolver().openFileDescriptor(Uri.parse(uriImage), "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
fullImageView.setImageBitmap(image);
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
}
}
Code for pick image from gallery:
btn.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
Code for OnActivityResult of gallery
@SuppressLint("NewApi")
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = intent.getData();
String a = selectedImageUri.getPath();
if (Build.VERSION.SDK_INT < 19) {
try
{
String imageUri = selectedImageUri.toString();
parcelFileDescriptor = getContentResolver().openFileDescriptor(selectedImageUri, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
fullImageView.setImageBitmap(image);
catDialog.dismiss();
editor = sharedpreferences.edit();
editor.putString("imageUri", imageUri);
editor.commit();
editor.remove("AvailImagePath").commit();
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
}
else
{
try
{
String imageUri = selectedImageUri.toString();
parcelFileDescriptor = getContentResolver().openFileDescriptor(selectedImageUri, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
fullImageView.setImageBitmap(image);
editor = sharedpreferences.edit();
editor.putString("imageUri", imageUri);
editor.commit();
editor.remove("AvailImagePath").commit();
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
}
}
}
}
Permission in manifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />
Above Code Working fine in older version but problem occur only in kitkat
There is no problem during pick image....it working fine.
Problem occur When i use shared Preference value to set image: when application start again
Log displaying some security level exception.
