[android-developers] Database design
I'm writing an app with a local SQLite DB stored on the device and I wanted to periodically have the app write data to a database located on a web host or Amazon's EC2. EC2 (e.g.) will store numbers from multiple users databases into one database, then crunch numbers from that database and store the statistics into a series of tables. My device will pull the data from these tables to display the statistics - most likely stored in another database located on the device. In short, User updates the database on the tablet or phone --- Tablet or phone sends data to EC2 (or other web host) --- EC2 crunches numbers and sends calculated data (statistics) to tables --- Tablet or phone pulls data from EC2 for display to user. Would I be looking at a content provider at EC2 (e.g.), or should I use a MySQL database on the EC2 end? What should my architecture be for this type of setup? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] NEWBIE needs help with Android Tab Widget tutorial
Chris, You should only add the intent-filter into one activity. Intents are communication channels between the layout and the code (to put it roughly). When you have an intent in an activity, that activity is the main communication point of the app. Here's an example from the Dashboard Demo at this site: http://blahti.wordpress.com/2011/03/14/build-dashboard-ui-for-android/. The application then calls the other activities from within the code. ?xml version=1.0 encoding=utf-8? manifest xmlns:android=http://schemas.android.com/apk/res/android; package=com.wglxy.example.dash1 android:versionCode=1 android:versionName=1.0 application android:theme=@style/Theme.D1 android:icon=@drawable/icon android:label=@string/app_name activity android:name=.HomeActivity android:label=@string/app_name intent-filter action android:name=android.intent.action.MAIN / category android:name=android.intent.category.LAUNCHER / /intent-filter /activity activity android:name=.F1Activity android:theme=@style/Theme.D1 android:label=@string/title_feature1 / activity android:name=.F2Activity android:theme=@style/Theme.D1 android:label=@string/title_feature2 / activity android:name=.F3Activity android:theme=@style/Theme.D1 android:label=@string/title_feature3 / activity android:name=.F4Activity android:theme=@style/Theme.D1 android:label=@string/title_feature4 / activity android:name=.F5Activity android:theme=@style/Theme.D1 android:label=@string/title_feature5 / activity android:name=.F6Activity android:theme=@style/Theme.D1 android:label=@string/title_feature6 / activity android:name=.AboutActivity android:theme=@style/Theme.D1 android:label=@string/title_about / activity android:name=.SearchActivity android:theme=@style/Theme.D1 android:label=@string/title_search / /application uses-sdk android:minSdkVersion=8 / /manifest *Joel C.

Jeff knows the value of the developer community. I'm sure he will be more open to the community at a later time.
