I think the problem is that you need to close the db when your activity is destroyed. Try adding this to your activity: @Override protected void onDestroy() { super.onDestroy(); if (openHelper != null) { openHelper.close(); } if (cdh != null) { cdh.close(); } } and add this to your CallDataHelper class: public void close() { … Read more
You always have to specify a content provider when implementing a SyncAdapter, but that’s not to say it actually has to do anything. I’ve written SyncAdapters that create accounts and integrate with the “Accounts & sync” framework in Android that don’t necessarily store their content in a standard provider. In your xml/syncadapter.xml: <sync-adapter xmlns:android=”http://schemas.android.com/apk/res/android” android:accountType=”com.company.app” … Read more
In addition to those u can see the list of fields in sms content provider by using following code: private void displaySmsLog() { Uri allMessages = Uri.parse(“content://sms/”); //Cursor cursor = managedQuery(allMessages, null, null, null, null); Both are same Cursor cursor = this.getContentResolver().query(allMessages, null, null, null, null); while (cursor.moveToNext()) { for (int i = 0; i … Read more
It’s an old question, but I was looking at doing something similar recently. With the Build flavours, its really straight forward now. Specify the BuildConfigField in the gradle file: productFlavors { free { applicationId “com.example.free” buildConfigField ‘String’, ‘AUTHORITY’, ‘”com.example.free.contentprovider”‘ } paid { applicationId “com.example.paid” buildConfigField ‘String’, ‘AUTHORITY’, ‘”com.example.paid.contentprovider”‘ } Specify the provider authority in the … Read more
This question relates to batch operation on a content provider. The example is modified from this related question. When creating a batch of operations first create a list of operations to perform using: ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(); then apply them to the content provider using the applyBatch method. ContentProviderResult[] results = this.getContentResolver().applyBatch(FooBar.AUTHORITY, operations); That … Read more
It automatically schedules all your server-side and synchronization DB access in a background thread. However, in your application frontend, the Content Resolver/Provider will normally execute queries/transactions from the UI thread by default. You must perform all transactions asynchronously (i.e. using a CursorLoader) to ensure that your application runs smoothly on the UI side It localizes … Read more
If you are using contentProvider then you have to do it like count(*) AS count. If you use cursor.getCount(), that would not be as efficient as the above approach. With cursor.getCount() you are fetching all the records just to get counts. The entire code should look like following – Cursor countCursor = getContentResolver().query(CONTENT_URI, new String[] … 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
Did you call setNotificationUri(ContentResolver cr, Uri uri) on the Cursor before returning it in ContentProvider.query()? And did you call getContext().getContentResolver().notifyChange(uri, null) in the ‘insert’ method of your ContentProvider? EDIT: To get a ContentResolver call getContext().getContentResolver() in your ContentProvider.
My solution to this problem has actually been to avoid relying on a single FileProvider parsing multiple authorities. While this doesn’t directly address the question as stated, I’m posting it for posterity. I updated my library to leverage an empty subclass of FileProvider, so that the library’s updated manifest provider entry is now: <provider android:name=”.flow.email.screenshot.BugShakerFileProvider” … Read more
