what to do,is there any refrence to it
Create a file and store the image in SD card as like the following:
// Declaration :
private Activity activity;
// Initialization :
activity = MainActivity.this;
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
File photo = new File(Environment.getExternalStorageDirectory()
+ "/.SomeWhereInSD", "photoToShare.png");
saveImage.setDrawingCacheEnabled(true);
saveImage.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
saveImage.post(new Runnable() {
public void run() {
Bitmap bitmap = null;
System.gc();
bitmap = Bitmap.createBitmap(saveImage.getDrawingCache(true));
saveImage.setDrawingCacheEnabled(false);
OutputStream outStream = null;
try {
outStream = new FileOutputStream(photo.getAbsolutePath());
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
myImage.setImageBitmap(myBitmap);
} catch (FileNotFoundException e) {
} catch (IOException e) {
} catch (OutOfMemoryError out) {
}
};
});
}
});
