I am using an custom view and in that i am using an canvas in which a user can draw anything and after that i want to save that image in sd card bt was not able to do that. Don't know what is going on.
else if(view.getId()==R.id.save_btn){
//save drawing
AlertDialog.Builder saveDialog = new AlertDialog.Builder(this);
saveDialog.setTitle("Save drawing");
saveDialog.setMessage("Save drawing to device Gallery?");
saveDialog.setPositiveButton("Yes", new DialogInterface.OnClickListener(){
private FileOutputStream fOut;
public void onClick(DialogInterface dialog, int which){
//save drawing
drawView.setDrawingCacheEnabled(true);
//attempt to save
String imgSaved = MediaStore.Images.Media.insertImage(
getContentResolver(), drawView.getDrawingCache(),
UUID.randomUUID().toString()+".png", "drawing");
//feedback
if(imgSaved!=null){
Toast savedToast = Toast.makeText(getApplicationContext(),
"Drawing saved to Gallery!", Toast.LENGTH_SHORT);
savedToast.show();
}
else{
Toast unsavedToast = Toast.makeText(getApplicationContext(),
"Oops! Image could not be saved.", Toast.LENGTH_SHORT);
unsavedToast.show();
}
drawView.destroyDrawingCache();
}
});
saveDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which){
dialog.cancel();
}
});
saveDialog.show();
}

I am always getting this message while trying to save image...."Oops! Image could not be saved.".....
I had this issue in the Emulator (Android 4.4) and turns out it's due to an Android bug, where it happens when the user hasn't taken a photo on the device before (i.e. gallery is empty and hasn't been initialized.). The workaround is to initialize the photo directory manually:
void fixMediaDir() {
File sdcard = Environment.getExternalStorageDirectory();
if (sdcard != null) {
File mediaDir = new File(sdcard, "DCIM/Camera");
if (!mediaDir.exists()) {
mediaDir.mkdirs();
}
}
}
Not sure if this is fixed in later versions of Android.
A bit late answer, but still...
Not sure which is line 238, but probably the reason is here:
String imgSaved = MediaStore.Images.Media.insertImage( getContentResolver(), drawView.getDrawingCache(), UUID.randomUUID().toString()+".png", "drawing");
Since the method is within a click listener getContentResolver
may be returning a Resolver different from the one for the application. Either save a private reference to the content resolver, or you could try replacing getContentResolver
with MainActivity.this.getContentResolver()
:
String imgSaved = MediaStore.Images.Media.insertImage( MainActivity.this.getContentResolver(), drawView.getDrawingCache(), UUID.randomUUID().toString() + ".png", "drawing");
Alternatively, it might be a permissioning problem. Make sure in the manifest you have:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
One final note, the result of insertImage
is an URI, imgSaved
is not the best name for that variable :)
