We create a BaseActivity which contains all the common functionality but we won't declare it in the AndroidManifest.xml file. The bottom region is a simple ImageButton. This use Android Download Manager to: download the file and added it to the Gallery. We will discuss more about it as we take up each case. This method can be used to download an image from the internet using a url in Android. We hide the widgets which are not applicable for a particular case. The center region is a ScrollView containing all the widgets required to handle the 3 cases. The top region of the screen is a RelativeLayout with a ImageButton and a Spinner. Here are some excerpts from the layout file. However, we will create separate Activity for each case to keep our code manageable. We will create a single layout file to handle the 3 cases since they are almost similar. I am getting these errors Can any one help me to resolve the errors.The app allows user to create a note, a checklist, and a snapshot. On click of buttonLoadPicture button, we need to trigger the intent for Image Gallery. We now need to write some Java code to actually handle the button click. Step 3: Android Java Code to trigger Image Gallery Intent Note that the id of Image view is imgView and that of Button is buttonLoadPicture. So our Android’s app UI is very simple, One LinearLayout to organize Image view and Button linearly.
