I would argue it is definitely a good idea to use a ContentProvider even if you don’t intend to make it public. It’s good practice to provide the extra level of abstraction over your data to make it easier to change internally. What if you decide to change the underlying database structure at a later … Read more
Here is the answer. Dont forget to register the content observer with this method: registerContentObserver (Uri uri, boolean notifyForDescendents, ContentObserver observer) And then you can create it like this. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.getApplicationContext() .getContentResolver() .registerContentObserver( android.provider.CallLog.Calls.CONTENT_URI, true, new MyContentObserver(handler)); } class MyContentObserver extends ContentObserver { public MyContentObserver(Handler h) { super(h); } @Override … Read more
The SmsWriteOpUtils class uses reflection to access methods of the AppOpsManager Service in order to enable/disable a non-default SMS app’s write access to the SMS Provider in API Level 19 (KitKat). Once set, an app’s access mode will be retained until it is reset, or the app is uninstalled. Enabling an app’s write access allows … Read more
It is possible to expose a file stored in your apps private directory via a ContentProvider. Here is some example code I made showing how to create a content provider that can do this. Manifest <manifest xmlns:android=”http://schemas.android.com/apk/res/android” package=”com.example.providertest” android:versionCode=”1″ android:versionName=”1.0″> <uses-sdk android:minSdkVersion=”11″ android:targetSdkVersion=”15″ /> <application android:label=”@string/app_name” android:icon=”@drawable/ic_launcher” android:theme=”@style/AppTheme”> <activity android:name=”.MainActivity” android:label=”@string/app_name”> <intent-filter> <action android:name=”android.intent.action.MAIN” /> … Read more
The authority, as listed in android:authorities must be unique. Quoting the documentation for this attribute: To avoid conflicts, authority names should use a Java-style naming convention (such as com.example.provider.cartoonprovider). Typically, it’s the name of the ContentProvider subclass that implements the provider
Calling requestSync() will only work on an {Account, ContentAuthority} pair that is known to the system. Your app needs to go through a number of steps to tell Android that you are capable of synchronizing a specific kind of content using a specific kind of account. It does this in the AndroidManifest. 1. Notify Android … Read more

I wrote a simple CursorLoader that does not need a content provider: import android.content.Context; import android.database.Cursor; import android.support.v4.content.AsyncTaskLoader; /** * Used to write apps that run on platforms prior to Android 3.0. When running * on Android 3.0 or above, this implementation is still used; it does not try * to switch to the framework’s … Read more
Using FileProvider from support library you have to manually grant and revoke permissions(at runtime) for other apps to read specific Uri. Use Context.grantUriPermission and Context.revokeUriPermission methods. For example: //grant permision for app with package “packegeName”, eg. before starting other app via intent context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION); //revoke permisions context.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION); As a … Read more
