问题 I am using an image to set as the background for all my activities but it was causing a memory overflow issue and crash the app. Now I am unbinding my drawables on pause() and on Destroy() in my activity and now it shows blank screen on pressing back button. So how can I avoid this without using extra memory. protected void onPause(){ super.onPause(); unbindDrawables(findViewById(R.id.login_root)); } protected void onDestroy() { unbindDrawables(findViewById(R.id.login_root)); super.onDestroy(

问题 I have an app where I have downloaded an image file from the web and I save this file in external storage. Later, to add this image to the media store, I call: MediaStore.Images.Media.insertImage(getContentResolver(), fullPath, "IMG_"+System.currentTimeMillis(),null); However, my picture always adds to the end of the gallery - it thinks that the picture was taken in 1970.

问题 I'm trying to create an Android ListView that will look like Instagram pictures feed or Facebook's. I'm getting Out Of Memory Exception on my Galaxy Nexus after loading some images (only a few). I scaled them, but still, the number of images isn't fixed and theoretically can be unlimited. On Facebook and Instagram they load lots of images and other data and it works well. What do you think? Can i achieve those performances with native Android coding? If i'll create a HTML5 feed (like Facebook

问题 I'm trying to import a 600x600 PNG I made into my Android project so that I can use it as a full-sized image in an Activity. Dragging and dropping it onto my /res folder just puts it in that folder, which of course generates an "invalid resource directory name" error. I can drop it into any of the /res/drawable folders and that works fine, except then it's only in that one folder. Surely, there's an inbuilt tool which can take my image and scale it appropriately for each /res/drawable folder.
