For what ever reason I can't fix this problem... (Mind you, I have
been messing with it and searching for about 3 hours even though it is
probably really simple)
I have 3 files, my wallpaper class, my wallpapersettings class, and my
wallpapersettings.xml
in my preference file I have:
<Preference
android:title="Background Image"
android:summary="Select an Image for the Background"
android:key="imagePref" />
in my wallpapersettings class I have: (inside of onCreate)
Preference customPref = (Preference) findPreference("imagePref");
if(customPref == null)
{
customPref = new Preference(getBaseContext());
}
customPref.setOnPreferenceClickListener(new
OnPreferenceClickListener()
{
public boolean onPreferenceClick(Preference preference)
{
/*Toast.makeText(getBaseContext(), "The custom preference
has been clicked", Toast.LENGTH_LONG).show();
SharedPreferences customSharedPreference =
getSharedPreferences("imagePref", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor =
customSharedPreference.edit();
editor.putString("imagePref","The preference has been
clicked");
editor.commit();
*/
startActivityForResult(new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI), 1);
return true;
}
});
and outside of onCreate:
@Override
public void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1)
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = data.getData();
Log.d("IMAGE SEL", "" + selectedImage);
// TODO Do something with the select image URI
SharedPreferences customSharedPreference =
getSharedPreferences("imagePref", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = customSharedPreference.edit
();
editor.putString("imagePref", getRealPathFromURI
(selectedImage));
Log.d("IMAGE SEL", getRealPathFromURI(selectedImage));
editor.commit();
}
}
in my wallpaper class I have:
String imageBg = mPrefs.getString("imagePref", "Bad Image");
Bitmap bm;
public void onSharedPreferenceChanged(SharedPreferences prefs, String
key)
{
imageBg = prefs.getString("imagePref", "Bad Image");
Log.d("CHECK PREF", prefs.getString("imagePref", "wtf"));
getBackground();
}
void getBackground()
{
File f = new File(Environment.getExternalStorageDirectory(),
imageBg);
FileInputStream is = null;
try
{
is = new FileInputStream(f);
}
catch (FileNotFoundException e)
{
Log.d("error: ",String.format( "ShowPicture.java file[%s]
Not Found", imageBg));
return;
}
bm = BitmapFactory.decodeStream(is, null, null);
}
When my code is ran, I get the correct file path in LogCat from the
wallpapersettings class. (it reports: /sdcard/DCIM/image.jpeg)
However, my wallpaper class says that it cannot find it when I try to
see what my Preference saved. Any one have any idea what im doing
wrong here? if I did not provide enough code for you to help me, let
me know
